Theological Vocabulary

The words worth knowing

Theology has a working vocabulary, and most of it is less intimidating than it sounds. Propitiation is a word about anger being turned away. Eschatology just means last things. Here is what each one means, where it came from, and where you will run into it. Where traditions use a word differently, the entry says so.

150 words

A

Accommodation

scripture

The idea that God speaks down to our capacity, as a parent uses small words with a child. Calvin's image was of a nurse lisping.

You will hear it: In discussions of why Scripture describes the world the way its first readers saw it, with a solid sky and a stationary earth.

Traditions use it differently

How far accommodation extends is one of the real questions behind debates over inerrancy and over Genesis. All sides use the principle; they disagree about whether it covers only the manner of speaking or also the incidental furniture of an ancient worldview.

Adoption

salvation

Being made a child of God with full legal standing, not a servant and not a guest. In the Roman world an adopted son was an heir in every sense, sometimes more securely than a natural one.

You will hear it: In Romans 8 and Galatians 4. J. I. Packer called it the highest privilege the gospel offers, higher even than justification.

Romans 8:15See also justification, union with christ

Allegory and the fourfold sense

scripture

The medieval method of reading a passage on four levels: literal, allegorical (what it says about Christ and the faith), moral (how to live), and anagogical (what it says about the end). A rhyme summarized it for students.

Traditions use it differently

The Antiochene fathers pushed back against Alexandrian allegory in the fourth century, and the Reformers largely rejected the fourfold method for the plain sense, though Luther kept using allegory when it suited him. Modern scholarship has been reconsidering premodern reading rather than simply dismissing it, on the grounds that the Fathers were often asking better questions than they are given credit for.

Amillennialism

ay-mil-EN-ee-ul-izmlast things

That the thousand years are the present church age, symbolic rather than a future period, with Christ reigning now.

You will hear it: The majority view in Catholic, Orthodox, Lutheran, Reformed and Anglican teaching.

Annihilationism

last things

The view that the finally lost cease to exist rather than suffering forever. Usually called conditional immortality by those who hold it, since the claim is about what immortality is rather than about how severe the punishment is.

You will hear it: In the long argument over hell, and in the phrase the second death.

Traditions use it differently

A minority position with a real pedigree, held in the early church by Arnobius, defended in the modern era by John Stott tentatively, John Wenham, Edward Fudge, and Anglican evangelicals among others. The traditional view of eternal conscious punishment remains the majority across Catholic, Orthodox, and Protestant teaching, and several confessions rule the alternative out by name.

Anthropomorphism

God

Speaking of God in human terms: his arm, his eyes, his changing his mind, his walking in the garden.

You will hear it: Whenever someone asks whether God really has hands, or really regretted making humanity in Genesis 6.

Traditions use it differently

How far the language reaches is a genuine question, not a dodge. Classical theology treats it as accommodation, God speaking in a register creatures can hear. Open theists argue that some of it, especially texts where God relents or is grieved, reports something real about how God relates to time and to us rather than being figurative.

Genesis 6:6See also immutability, impassibility

Apocrypha

uh-POK-rih-fuhscripture

Books included in the Greek Old Testament but not in the Hebrew Bible: Tobit, Judith, Wisdom, Sirach, Maccabees and others.

Roots: Greek apokryphos, hidden away.

Traditions use it differently

Catholics and Orthodox receive most of them as Scripture and call them deuterocanonical, a second canon rather than a lesser one. Protestants generally do not, though the King James printed them in a separate section and Luther called them useful to read.

Apostasy

salvation

Falling away from the faith. Not doubt, and not a season of struggle, but a settled abandonment.

Roots: Greek apostasia, a standing away or defection.

Traditions use it differently

Whether a true believer can commit it is precisely the perseverance question. The warning passages in Hebrews are the battleground, and every tradition has to do something with them.

Apostolic succession

church

The claim that authority in the church passes down through an unbroken line of bishops from the apostles, by the laying on of hands.

Traditions use it differently

Catholic, Orthodox, and Anglican traditions hold it, and disagree about whose lines are valid. Rome declared Anglican orders invalid in 1896; Anglicans dispute the reasoning. Most Protestant traditions substitute succession in apostolic teaching for succession in office, arguing that faithfulness to the apostles' doctrine is what the New Testament actually requires.

Apostolic succession

app-uh-STOL-ikchurch

The claim that bishops stand in an unbroken line of ordination reaching back to the apostles, and that this is what makes their ministry valid.

You will hear it: Central to Catholic and Orthodox understandings of ministry.

Traditions use it differently

Anglicans generally maintain it; most Protestant bodies hold that succession is in apostolic teaching rather than in a chain of hands.

See also episcopal

Arianism

Christ

The fourth-century teaching that the Son is the highest creature, made by the Father before all ages but not eternal. Its slogan: there was when he was not.

You will hear it: The reason the Nicene Creed says begotten not made, and one substance with the Father. Every clause of that section was written to be unsignable by Arius.

Traditions use it differently

Condemned at Nicaea in 325 and again at Constantinople in 381, and rejected by every historic tradition since. Worth knowing accurately: Arius was not a fool, and his concern was to protect God's oneness. The council judged that his solution cost more than it saved, because a creature cannot save.

Arminianism

ar-MIN-ee-un-izmsalvation

The stream named for Jacob Arminius, holding that God's saving grace goes before us and enables a genuine response, and that it can be resisted.

You will hear it: Methodist, Wesleyan, Pentecostal, Free Will Baptist and many others.

Traditions use it differently

Often caricatured as salvation by human effort. Arminians reply that no one seeks God unaided and that prevenient grace does the enabling.

Ascension and session

Christ

Christ's going up, and his sitting down. The ascension is his departure in the body; the session is his continuing reign at the Father's right hand, from which he intercedes.

You will hear it: In every creed, and badly neglected in preaching. Hebrews is largely about what Christ is doing now.

Hebrews 7:25See also parousia, incarnation

Aseity

ay-SEE-ih-teeGod

God's self-existence. He does not depend on anything, was not caused, and would lack nothing if the universe had never been.

Roots: Latin a se, from himself.

You will hear it: Behind the name given at the burning bush, and behind Paul telling the Athenians that God is not served by human hands as though he needed anything.

Acts 17:24-25See also divine simplicity, immutability

Assurance

salvation

Knowing that you are right with God, and how you could know it.

You will hear it: In pastoral conversations more than in academic ones. It is the doctrine people actually lose sleep over.

Traditions use it differently

The Reformers made assurance ordinary and expected, against a late medieval piety in which it was presumptuous. Catholic teaching still holds that no one has infallible certainty of final perseverance apart from special revelation, while affirming confident hope. Wesley located assurance in the witness of the Spirit. Puritan practice, in trying to test it, sometimes produced the anxiety it meant to cure.

Atonement

salvation

The restoring of a broken relationship between God and people through Christ's death.

Roots: Coined in English, literally at-one-ment, one of the few theological terms that began in English rather than Greek or Latin.

You will hear it: Everywhere. How it works is one of the questions with its own article in this hall.

Autocephalous

aw-toh-SEF-uh-luschurch

Self-headed: an Orthodox church that governs itself and appoints its own head, while remaining in full communion with the others.

Roots: Greek autos, self, and kephale, head.

You will hear it: The Greek, Russian, Serbian and Romanian churches are each autocephalous.

See also episcopal

Autocephaly

aw-toh-SEF-uh-leechurch

The status of being self-governing, held by each of the national Orthodox churches while remaining in full communion with the rest.

B

Beatific vision

last things

Seeing God face to face. In Catholic and much classical Protestant theology, the final and complete happiness of the redeemed.

Traditions use it differently

Orthodoxy affirms the substance while refusing the term as the West uses it, since the divine essence is held to be unknowable even in glory; what is seen is the uncreated light. Aquinas and Palamas are the usual names attached to the two accounts, and the disagreement is old and unresolved.

1 Corinthians 13:12See also theosis, new creation

Begotten

bih-GOT-unChrist

Born of, rather than made. The creeds say the Son is begotten of the Father, not created, to insist he is of the same being as the Father rather than the first and greatest of his works.

Roots: Old English, the past participle of beget. The Greek is monogenes, only-begotten or one of a kind.

You will hear it: Nicene Creed: begotten, not made, of one substance with the Father.

Traditions use it differently

Whether monogenes means only-begotten or unique is debated; many modern translations render it one and only. The creedal point does not rest on that translation.

C

Calvinism

KAL-vin-izmsalvation

The Reformed stream, named for John Calvin, holding that salvation is entirely God's work from beginning to end and that his choice of whom to save is unconditional.

You will hear it: Presbyterian and Reformed churches, and a substantial minority of Baptists.

Traditions use it differently

The five points summarised at Dort were an ANSWER to the Arminian articles, not a summary Calvin wrote. Many who hold the theology dislike the label.

Catholic

church

Universal. When lowercase in a creed it means the whole church everywhere, which is why Protestants can say it without hesitation.

Roots: Greek katholikos, according to the whole.

Cessationism

sess-AY-shun-izmchurch

The view that the miraculous gifts, tongues and prophecy and healing, ceased with the apostles or with the completion of Scripture.

Traditions use it differently

Continuationists reply that no text says so, and that the case rests on inference. The question barely existed before 1906.

Chrismation

kriz-MAY-shunchurch

Anointing with holy oil, given in Orthodoxy immediately after baptism, including to infants. The Eastern counterpart of confirmation.

Roots: Greek chrisma, an anointing; the same root as Christ, the anointed one.

See also sacrament

Church government

church

How a church is governed. Episcopal means by bishops, presbyterian means by a council of elders, congregational means by the local congregation.

You will hear it: The words name structures, not denominations, though several denominations are named after theirs.

Concupiscence

kon-KYOO-pih-sensesalvation

Disordered desire. The pull toward what is wrong that remains in a person even after baptism and conversion.

Traditions use it differently

Catholic teaching holds that baptism removes original sin's guilt but leaves concupiscence, which is not itself sin though it inclines toward it. The Reformers rejected that distinction and insisted the remaining disorder is genuinely sin, which is why Luther described the Christian as simultaneously justified and a sinner.

Confession

kun-FESH-unchurch

A longer, detailed doctrinal statement that defines a tradition. Westminster, Augsburg, and the Belgic Confession are examples. The same word also means admitting sin.

Roots: Latin confiteri, to acknowledge or declare.

You will hear it: Confessional churches require ministers to subscribe to one.

Traditions use it differently

How binding it is varies enormously: some require full subscription, some subscription to the system of doctrine, and some treat confessions as descriptive only.

See also creed

Congregational

kong-gruh-GAY-shun-ulchurch

Church government in which each local congregation governs itself and no outside body can bind it.

You will hear it: Baptist, Congregationalist, most non-denominational churches.

Connexional

kuh-NEK-shun-ulchurch

Methodist government, in which churches belong to a connexion and ministers are appointed to congregations by it rather than called by them.

Roots: An older spelling of connectional, kept as a term of art.

Consubstantiation

kon-sub-stan-she-AY-shunchurch

A term often used for the Lutheran view that Christ's body and blood are present along with the bread and wine.

Traditions use it differently

Lutherans generally reject the word. They affirm a real presence in, with and under the elements while declining to explain the mechanism, and consubstantiation names an explanation they did not offer.

Continuationism

kun-tin-yoo-AY-shun-izmchurch

The view that the gifts described in Acts and 1 Corinthians are for the whole church age and are available now.

You will hear it: Pentecostal and charismatic churches, and a growing number of others.

See also cessationism

Covenant

scripture

A binding relationship with obligations, sworn rather than merely agreed. The organizing idea of the whole Bible, which is why its two halves are called Testaments, an older word for the same thing.

You will hear it: Noah, Abraham, Moses, David, and the new covenant in Christ are the usual five.

Traditions use it differently

How the covenants relate is one of the deepest dividing lines in Protestant theology. Covenant theology reads them as successive administrations of one covenant of grace, which is why it baptizes infants. Dispensationalism reads them as distinct arrangements with a lasting distinction between Israel and the church. Most Catholic and Orthodox theology works with neither system.

Covenant theology

KUV-uh-nuntscripture

Reading the whole Bible as one continuous covenant story, with the church continuous with Israel rather than a separate programme.

You will hear it: Reformed and Presbyterian churches; the reason they baptise infants on the pattern of circumcision.

Traditions use it differently

Dispensationalism divides history into distinct eras and keeps Israel and the church permanently distinct. The disagreement drives much of how each side reads prophecy.

Credobaptism

KRED-oh-bap-tizmchurch

Baptism only of those who can profess faith for themselves.

Roots: Latin credo, I believe.

Creed

KREEDchurch

A short, fixed statement of belief said together. The Apostles' and Nicene Creeds are the two most Christians share.

Roots: Latin credo, I believe, which is the first word of both.

You will hear it: Recited in worship in most historic traditions.

Traditions use it differently

Some traditions, particularly Baptist and Restorationist, decline to use creeds as tests of fellowship, holding that Scripture alone should bind. They usually still agree with the content.

Creed and confession

study

A creed is a short, universally received statement of faith, like the Nicene. A confession is a longer, denominationally specific document, like Westminster, Augsburg, or the Belgic.

You will hear it: Some traditions call themselves confessional, meaning their ministers subscribe to a particular document, not merely that they have opinions.

Traditions use it differently

Some churches describe themselves as having no creed but the Bible. Critics note that this is itself a creedal statement, and that every church teaches something in particular.

D

Dead Sea Scrolls

scripture

Manuscripts found at Qumran from 1947 onward, dating from roughly the third century BC to the first century AD, including the oldest copies of nearly every Old Testament book.

You will hear it: In any argument about whether the text has been changed. The great Isaiah scroll is a thousand years older than the previously oldest Hebrew Isaiah and is substantially the same document.

Traditions use it differently

They also complicate the picture, since some scrolls agree with the Septuagint against the Masoretic Text, showing more than one Hebrew text form circulating. That is a finding about textual history, not about reliability.

Deification

day-ih-fih-KAY-shunsalvation

The Latin word for what Orthodoxy calls theosis: being transformed into the likeness of God by grace, without becoming God in essence.

You will hear it: Common in Orthodox writing, and present in the Fathers of both East and West.

Deuterocanonical

scripture

The books Catholic and Orthodox Bibles include in the Old Testament and Protestant Bibles do not: Tobit, Judith, Wisdom, Sirach, Baruch, 1 and 2 Maccabees, and additions to Esther and Daniel. Orthodox canons include several more.

Roots: Second canon, meaning recognized later, not second-rate. Protestants call the same books Apocrypha, meaning hidden, which is why the label you use already signals your answer.

You will hear it: In every discussion of why Catholic Bibles are thicker. The 1611 King James included these books, printed between the Testaments.

Traditions use it differently

Trent defined them as canonical in 1546. Protestants followed Jerome's preference for the Hebrew canon. Orthodoxy accepts them without having defined the list as tightly. Worth knowing: Jesus and the apostles quote the Septuagint, which contained them, but never quote these particular books as Scripture.

Dispensationalism

study

A system, developed from the 1830s, that divides history into distinct eras in which God deals with humanity in different ways, and maintains a lasting distinction between Israel and the church.

You will hear it: Behind the Scofield Reference Bible, most American prophecy preaching, and the Left Behind novels.

Traditions use it differently

Covenant theology, the older Reformed alternative, reads the covenants as one unfolding plan and sees the church as continuous with Israel. Progressive dispensationalism has moved substantially toward that position. Catholic and Orthodox theology work with neither framework.

Dispensationalism

dis-pen-SAY-shun-ul-izmlast things

A framework dividing history into distinct eras in which God deals with people differently, and holding Israel and the church to be permanently distinct.

You will hear it: Bible churches, much of American evangelicalism, and the source of the popular rapture timeline.

Traditions use it differently

Covenant theology reads Scripture as one continuous covenant story and sees the church as continuous with Israel. The disagreement drives much of how each side reads prophecy.

Divine simplicity

God

That God is not assembled out of parts. His attributes are not components he possesses but ways of naming the one undivided reality he is, so that God does not have love, he is love.

You will hear it: In classical theism from the Fathers through Aquinas, and in a lively modern argument about whether it can be squared with the personal God of the narratives.

Traditions use it differently

Affirmed across Catholic, Orthodox, and confessional Protestant tradition. Orthodoxy qualifies it with the essence and energies distinction. A number of modern analytic and evangelical theologians have challenged it as more Greek than biblical, and others have defended it as the only way to keep God from becoming one more item in the universe.

Docetism

DOH-seh-tizmChrist

The early teaching that Christ only appeared to have a body and only seemed to suffer, since a truly divine being could not be subject to flesh and death.

Roots: Greek dokein, to seem.

You will hear it: 1 John is written partly against it, which is why it insists on what the apostles heard, saw, and touched.

Traditions use it differently

Rejected by every historic tradition, but worth knowing because the instinct behind it keeps returning: a piety that finds the physical embarrassing, that treats the body as a container for the real you, or that cannot say God actually died. The creeds insist on suffered, died, and was buried for exactly this reason.

Dogma and dogmatics

study

A dogma is a teaching a church has formally defined as binding. Dogmatics is the discipline of setting such teaching out in order.

Traditions use it differently

How much is dogma varies enormously. Catholicism has a defined and countable set. Orthodoxy treats the seven councils as dogmatic and resists adding. Most Protestant bodies have confessions rather than dogmas, and the difference in how binding those are is itself a difference between traditions.

E

Ecumenism

study

Work toward unity among Christian traditions.

Roots: Greek oikoumene, the inhabited world. The same root gives us ecumenical councils, meaning councils of the whole church.

Traditions use it differently

Vatican II committed the Catholic Church to it. The World Council of Churches has pursued it since 1948. Critics across traditions worry that unity purchased by vagueness is not worth having, and some conservative bodies decline to participate on that ground. The 1999 Joint Declaration on justification is the usual example of what it can achieve.

Eisegesis

eye-suh-JEE-sisstudy

Reading into the text what you brought with you. The opposite of exegesis, and the thing everyone accuses everyone else of.

Roots: Greek eis, into, against ex, out of.

You will hear it: In seminary classrooms and in comment sections, with roughly equal precision.

Episcopal

ee-PISS-kuh-pulchurch

Church government by bishops. From the Greek word for overseer, episkopos.

Roots: Greek episkopos, overseer, one of the New Testament words for a church leader.

You will hear it: Catholic, Orthodox, Anglican, and some Lutheran and Methodist bodies.

Eschatology

es-kuh-TOL-uh-jeelast things

The doctrine of last things: death, judgment, resurrection, and the age to come.

Roots: Greek eschatos, last.

Ex opere operato

eks OH-peh-ray oh-peh-RAH-tohchurch

From the work worked. That a sacrament is effective because of what Christ does in it rather than because of the worthiness of the minister or the intensity of the recipient.

You will hear it: In Catholic sacramental theology, and often misquoted as if it meant sacraments work automatically regardless of faith, which the doctrine explicitly denies for adults.

Traditions use it differently

Its point was pastoral: a corrupt priest cannot invalidate your baptism. The Donatists had argued otherwise in the fourth century and Augustine answered them. Protestant traditions accepted that answer while rejecting the wider framework built on it.

Exclusive psalmody

SAHM-uh-deechurch

The practice of singing only the biblical psalms in worship, and in stricter forms without instruments.

You will hear it: Some Scottish Presbyterian and Reformed churches.

Traditions use it differently

It follows from the regulative principle, that worship should include only what Scripture positively commands. Those who disagree hold that Scripture's silence permits rather than forbids.

See also liturgy

Expiation

eks-pee-AY-shunsalvation

The removal or covering of sin. Distinguished from propitiation, which is about turning away wrath: expiation acts on the sin, propitiation on the one offended.

Traditions use it differently

Which word translates the Greek hilasterion is a live argument, and translations differ. It is not merely lexical: it bears on whether the cross deals with guilt, with wrath, or with both.

Romans 3:25See also propitiation, atonement
F

Filioque

fil-ee-OH-kwayGod

The Latin phrase and the Son, added in the West to the Nicene Creed's statement that the Spirit proceeds from the Father.

Roots: Latin filioque, and from the Son.

You will hear it: One of the two stated causes of the split between East and West in 1054.

Traditions use it differently

The East objects both to the theology, holding that it confuses the persons, and to the procedure, that the West altered a creed agreed by an ecumenical council without one.

See also trinity, schism
G

General and special revelation

God

General revelation is what can be known of God from creation and conscience, available to everyone. Special revelation is what God has disclosed in particular: to Israel, in Scripture, and supremely in Christ.

You will hear it: In the first chapters of most systematic theologies, and in every argument about whether someone who never heard the gospel can know anything true about God.

Traditions use it differently

How much general revelation yields is disputed. Aquinas held that reason can establish God's existence. Barth resisted natural theology fiercely, holding that God is known only where he speaks. Calvin allowed a sense of divinity in all people while insisting sin distorts it.

Romans 1:20See also apologetics, theodicy

Gentile

study

Anyone who is not Jewish. Not a nationality and not a religion, simply the category of everyone outside Israel.

Roots: Latin gentilis, of a nation, translating Hebrew goyim and Greek ethne, both of which mean the nations. The same Greek word is rendered nations, Gentiles or pagans depending on the verse and the translator.

You will hear it: Constantly in Acts and the letters, where whether Gentiles could be included without becoming Jewish first is the central controversy of the early church.

Acts 15:1-21

Gnosticism

NOS-tih-sizmchurch

A family of second-century movements teaching that the material world is a mistake made by a lesser deity, and that salvation comes through secret knowledge.

Roots: Greek gnosis, knowledge.

You will hear it: Much of 1 John and Colossians reads as an answer to early forms of it, and the insistence in the creeds that God made heaven and earth is aimed at it.

Grace

salvation

God's favor given freely, not earned and not owed.

Roots: Greek charis, which also gives us charisma, gift.

Traditions use it differently

Traditions differ over whether grace can be resisted, whether it is given to all, and whether it works through the sacraments. Nobody disagrees that salvation is by grace.

H

High priest

study

The chief priest, the only person permitted into the most holy place, and then only on the Day of Atonement.

You will hear it: In the trial narratives, where the office had become a Roman political appointment. This is why the Gospels can refer to more than one high priest at the same time: Caiaphas held the post, and his father-in-law Annas, deposed by the Romans years earlier, still carried the title and the influence.

Traditions use it differently

Hebrews applies the title to Christ at length, which is a deliberate difficulty, since he was from Judah and not from Levi. The letter answers it by appealing to Melchizedek, a priest who appears in Genesis with no genealogy at all.

Hebrews 4:14-16See also most holy place, atonement

Higher and lower criticism

scripture

Lower, or textual, criticism asks what the original wording was. Higher criticism asks about sources, authorship, date, and how a book came together. The names describe the order of the questions, not their value.

Traditions use it differently

Textual criticism is used by everyone, including the most conservative translators. Higher criticism is where the fights are, especially the documentary hypothesis for the Pentateuch and questions of which letters Paul wrote. Traditions range from wholesale rejection to full adoption, and there are careful scholars at most points on that line.

Hypostatic union

hy-poh-STAT-ikChrist

That in Christ two natures, divine and human, are united in one person, without being mixed together and without either being diminished.

Roots: Greek hypostasis, an individual reality or person.

You will hear it: The Definition of Chalcedon, 451, is where the wording was settled.

I

Immersion

ih-MUR-zhunchurch

Baptism by going fully under the water, as against pouring or sprinkling.

Traditions use it differently

Baptists and others hold the Greek word baptizo means to immerse and that the mode is part of the meaning; others hold the mode is indifferent.

Immutability

God

God does not change in character, purpose, or being.

Traditions use it differently

How to hold this alongside passages where God is said to relent or to be grieved is an old question. Classical theism reads those as accommodated language; other approaches take them more directly.

Impassibility

God

That God is not acted upon from outside, and does not suffer as creatures do. Classically it means God's love is not a reaction he undergoes but an act he is.

Traditions use it differently

One of the sharpest reversals in modern theology. The tradition affirmed impassibility nearly unanimously. After the twentieth century's catastrophes, Moltmann and many others argued for a God who suffers with the world, and much contemporary preaching assumes it. Defenders of the older view reply that a God who is moved by suffering is a God who might be overcome by it, and that the cross is God acting rather than God being damaged.

Imputation

salvation

Crediting something to someone's account. In Reformed theology, Christ's righteousness credited to the believer and their sin credited to him.

You will hear it: In Reformed discussions of justification, and in the phrase the great exchange.

2 Corinthians 5:21See also justification, union with christ, merit

Indulgence

salvation

In Catholic teaching, the remission of temporal punishment for sins whose guilt is already forgiven. Not, as often assumed, permission to sin or the purchase of forgiveness.

You will hear it: The sale of them was the immediate trigger of Luther's ninety-five theses in 1517.

Traditions use it differently

Catholic doctrine retains indulgences while the Council of Trent abolished the sale of them and condemned the abuses. Protestant and Orthodox traditions reject the underlying account of a treasury of merit. Being accurate about what the doctrine claims is worth more than the caricature, since the actual sixteenth-century abuse was bad enough on its own terms.

See also purgatory, merit

Inerrancy and infallibility

scripture

Inerrancy usually means Scripture contains no errors of any kind in what it affirms. Infallibility usually means Scripture does not fail in its purpose of teaching what is necessary for salvation.

Traditions use it differently

The distinction matters. Some traditions affirm both, some affirm infallibility while declining the stronger term, and the words are used loosely enough that it is always worth asking what a particular speaker means.

Intermediate state

last things

The name theologians give to the stretch between a person's death and the general resurrection. Whether anything is experienced during it is exactly what is disputed.

You will hear it: Whenever a funeral raises the question of whether grandma is already with the Lord or waiting for the last day.

Traditions use it differently

Paul says to depart and be with Christ is far better, and that he would prefer to be absent from the body and at home with the Lord, which most traditions read as conscious fellowship immediately at death. Others point out that the New Testament calls the dead asleep more than fifteen times, that Paul's comfort to the bereaved in 1 Thessalonians 4 is the resurrection rather than an intermediate reunion, and that from the sleeper's side no time passes at all. Catholic teaching adds purgation for those who die in grace but imperfect.

Irenic and polemic

study

Two registers of theological writing. Irenic aims at peace and understanding; polemic aims at refutation. Both have their place, and confusing which one you are reading causes a lot of unnecessary anger.

Roots: Greek eirene, peace, and polemos, war.

J

Justification

juss-tih-fih-KAY-shunsalvation

Being declared right with God. A courtroom word: the verdict is not guilty, and the standing is restored.

Roots: Latin iustificare, to make or declare righteous, translating a Greek word from the law courts.

You will hear it: At the center of the Reformation, and of Romans and Galatians.

Traditions use it differently

Protestants have generally understood it as God declaring a sinner righteous on account of Christ, with righteousness credited rather than infused. Catholic teaching describes it as God making a person actually righteous, a process rather than a single verdict. The 1999 Joint Declaration between Lutherans and the Catholic Church found substantial agreement while leaving real differences.

K

Kenosis

ken-OH-sisChrist

The self-emptying of Christ described in Philippians 2, where he did not grasp at equality with God but took the form of a servant.

Roots: Greek kenoo, to empty.

Traditions use it differently

What exactly was emptied is disputed. Some hold he set aside the independent use of divine attributes; others that he added humanity without subtracting anything. The text says he emptied himself and does not specify of what.

Philippians 2:7See also incarnation, hypostatic union
L

Latria and dulia

LAT-ree-uh, DOO-lee-uhchurch

Latria is worship, due to God alone. Dulia is honour, given to saints. Catholic and Orthodox teaching holds the two to be different in kind, not degree.

Roots: Greek latreia, service or worship, and douleia, service of a servant.

Traditions use it differently

Protestants have often argued the distinction collapses in practice. Catholics and Orthodox reply that it is precisely the distinction the commandment turns on, and that they observe it.

Levite

study

A member of the tribe of Levi, set apart for service at the sanctuary. The priests were Levites, but most Levites were not priests.

Roots: From Levi, one of Jacob's sons. The distinction matters: priests descend specifically from Aaron, while other Levites did the music, the gatekeeping, the teaching and the carrying.

You will hear it: In Chronicles, which is far more interested in them than Samuel and Kings are, and in the parable of the good Samaritan, where a priest and a Levite both pass by.

Traditions use it differently

The Levites received no land, and were told the LORD was their inheritance instead, which is where the phrase comes from when the psalms apply it to anyone.

Numbers 18:20-24See also high priest

Liturgy

church

The set order of public worship.

Roots: Greek leitourgia, meaning public service or a work done for the people.

You will hear it: Often used as though it meant formal worship as opposed to informal, though every church has a liturgy in the sense of a pattern, whether printed or not.

Logos

LOH-gossChrist

Word. John opens his gospel by calling Christ the Logos who was with God and was God, deliberately using a term loaded with meaning for both Jewish and Greek readers.

Roots: Greek logos: word, reason, account, the rational principle ordering the cosmos in Stoic thought, and close to the Jewish figure of Wisdom in Proverbs 8.

You will hear it: In the prologue of John, and in every discussion of how the earliest Christians could confess a man as God.

John 1:1See also incarnation, hypostatic union
M

Magisterium

maj-iss-TEER-ee-umchurch

The teaching office of the Catholic Church: the pope and the bishops in communion with him, understood as authorized to interpret Scripture and tradition definitively.

Roots: Latin magister, teacher.

Traditions use it differently

Catholics distinguish levels: solemn definitions demand assent of faith, ordinary teaching demands religious submission, and most teaching is neither infallible nor trivial. Orthodoxy locates authority in the whole church expressed through councils, with no single see having the final word. Protestants hold sola scriptura, which does not mean rejecting tradition but denying it independent authority.

Marks of the church

church

How you tell a true church from something else. The creed names four: one, holy, catholic, apostolic. The Reformers proposed a shorter working test: the word rightly preached and the sacraments rightly administered.

Traditions use it differently

The two lists are answering different questions, which is why they coexist without resolving anything. The creedal marks describe what the church is; the Reformation marks were meant to let a congregation know whether to stay. Some traditions add church discipline as a third mark.

Masoretic Text

mass-oh-RET-ikscripture

The standard Hebrew text of the Old Testament, preserved and vowel-pointed by Jewish scribes called the Masoretes between roughly the seventh and tenth centuries.

You will hear it: In footnotes reading Hebrew, or MT, usually where it differs from the Septuagint or the Dead Sea Scrolls.

Traditions use it differently

It is the base text for nearly all Old Testament translation, and its accuracy was dramatically confirmed by the Dead Sea Scrolls. Where it differs from the Septuagint, translators must choose, and Orthodox tradition weights the Septuagint more heavily than Western churches do.

Merit

salvation

Whether and how a person's actions can deserve anything from God.

Traditions use it differently

The medieval distinction was between condign merit, which strictly deserves a reward, and congruent merit, which God graciously counts as fitting. The Reformers rejected the category for justification entirely. Catholic teaching holds that merit itself is a gift, since God crowns his own gifts in us, a line from Augustine that Trent quotes. Much Protestant polemic aims at a version of merit that Catholic theology also rejects.

Messiah

Christ

The anointed one. In Hebrew mashiach, in Greek christos, which is why Christ is a title and not a surname.

You will hear it: Kings, priests, and prophets were anointed. The expectation grew into hope for a coming deliverer from David's line.

See also logos, typology

Miaphysite

my-AH-fih-siteChrist

The Oriental Orthodox confession that Christ is one incarnate nature FROM two, fully God and fully human, without confusion or change.

Roots: Greek mia, one, and physis, nature.

Traditions use it differently

Historically labelled monophysite, one nature, by opponents. These churches reject that label, and recent joint declarations with Rome and Constantinople have affirmed a shared faith in different words.

Millennium

last things

The thousand years of Revelation 20. Premillennial, postmillennial, and amillennial name where Christ's return falls relative to it.

You will hear it: This hall has an article laying out all three.

Monergism and synergism

salvation

Two words for who is working. Monergism: God alone effects salvation. Synergism: God and the person work together, with God's grace always first and decisive.

Roots: Greek monos, alone, and syn, with, both joined to ergon, work.

Traditions use it differently

Reformed theology is monergistic about regeneration. Wesleyan, Arminian, Catholic, and Orthodox theology are synergistic in some form, though Orthodoxy means something particular by it and would reject the charge that grace is thereby made a junior partner. The labels get used as insults more often than as descriptions.

Monophysite

muh-NOF-ih-siteChrist

One nature. A label applied after Chalcedon to churches that would not accept its two-natures wording.

Traditions use it differently

The Oriental Orthodox churches reject the label as a misdescription and say miaphysite, one incarnate nature FROM two, fully God and fully human. Recent joint declarations with Rome and Constantinople affirm a shared faith in different words.

Most holy place

study

The innermost room of the tabernacle and temple, entered by one man on one day of the year. Older translations call it the holy of holies.

Roots: A Hebrew superlative built by repetition, holy of holies, the same construction as king of kings and vanity of vanities. It means the holiest, not two separate holy things.

You will hear it: In Leviticus 16, and in the accounts of the curtain tearing at the crucifixion. Worth knowing that throughout the second temple period this room was empty, because the ark never came back from Babylon.

Leviticus 16:2See also tabernacle, atonement
N

Nestorianism and monophysitism

Christ

The two errors Chalcedon steered between. One is charged with dividing Christ into two persons who cooperate; the other with merging his divinity and humanity into a single new nature.

Traditions use it differently

Both labels are contested by the churches they were applied to. The Assyrian Church of the East rejects the Nestorian label, and the Oriental Orthodox churches describe their position as miaphysite, one incarnate nature of the Word, not monophysite. Modern dialogues have produced joint statements finding that much of the split was about vocabulary rather than substance, though the churches remain separate.

New creation

last things

The renewal of heaven and earth that Scripture ends with. Not the destruction of the material world but its healing, with a city in it and the nations walking by its light.

You will hear it: Increasingly, in place of going to heaven, which is not how the New Testament describes the final hope.

Traditions use it differently

Traditions differ on how much continuity there is between this creation and the next, and on whether the present earth is renewed or replaced. 2 Peter 3:10 has been read both ways, and depends on a textual variant: some manuscripts say the earth will be burned up, the earliest say it will be found or laid bare.

Revelation 21:1-5See also resurrection, eschatology
O

Omniscience

God

God knows all things.

Traditions use it differently

Open theists argue that the future free choices of creatures are not yet there to be known, and that this limits nothing about God. The overwhelming majority of Christian traditions reject that and hold that God knows the future exhaustively.

Ordinance

OR-dih-nuncechurch

The word many Baptist and free-church traditions prefer to sacrament, for baptism and the Lord's Supper.

Traditions use it differently

The choice of word is the point: ordinance stresses obedience to a command, sacrament stresses that God is doing something through it.

See also sacrament

Original sin

salvation

The doctrine that what went wrong in Eden did not stay in Eden. Every person since is born into a condition of estrangement from God, not merely into a bad example.

Roots: The Latin phrase peccatum originale is Augustine's. The East had been describing the same wound for centuries without that vocabulary.

Traditions use it differently

The great East and West divide. Western theology after Augustine has generally held that guilt as well as corruption is inherited, which is why infant baptism was pressed so hard. Eastern Orthodoxy speaks of ancestral sin: we inherit mortality and a damaged nature, but not another person's guilt. Both agree we cannot heal ourselves. Pelagius denied the doctrine altogether and was condemned in 418.

Orthodox

church

Right belief or right worship. Lowercase it means holding sound doctrine; capitalized it names the Eastern Orthodox churches.

Roots: Greek orthos, straight, and doxa, opinion or glory.

P

Paedobaptism

PEE-doh-bap-tizmchurch

The baptism of infants, on the covenant pattern by which children of believers are included in the community.

Roots: Greek pais, child.

Parousia

pa-ROO-see-uhlast things

The second coming of Christ.

Roots: Greek for arrival or presence, used in the ancient world for the state visit of a king or emperor to a city.

Patriarchate

PAY-tree-ar-kutchurch

The office and territory of a patriarch, the senior bishop of one of the ancient sees: Rome, Constantinople, Alexandria, Antioch and Jerusalem.

Patristics

study

The study of the church fathers, roughly the first eight centuries of Christian writers.

You will hear it: Whenever an argument turns on what the early church actually believed, which it often does and which is usually more complicated than either side wants.

Pelagianism

salvation

The teaching, condemned in the fifth century, that human beings can take the first step toward God by their own will without grace.

You will hear it: Often thrown as an accusation. Semi-Pelagian is the milder charge, that grace is needed but the first move is ours. Arminians are frequently accused of it and consistently deny it.

Perichoresis

peh-rih-koh-REE-sisGod

The mutual indwelling of the three persons of the Trinity. Each fully in the others, without confusion and without separation.

Roots: Greek, roughly a going around. The Latin equivalent is circumincession.

You will hear it: Often glossed as the divine dance, which is a later and looser translation than the word supports but has stuck.

John 17:21See also trinity, hypostatic union

Perseverance of the saints

salvation

The teaching that those God truly saves will be kept by him to the end. Popularly, and misleadingly, once saved always saved.

You will hear it: The P in TULIP. Also every argument about whether someone who walked away was ever really in.

Traditions use it differently

Reformed and most Baptist theology affirm it. Wesleyan, Arminian, Catholic, and Orthodox teaching hold that a person can finally fall away, pointing to Hebrews 6 and the sheer number of New Testament warnings. Note that the Reformed version is not once saved always safe: it insists that the genuinely converted will in fact persevere in faith, which is a claim about evidence as much as about security.

Perspicuity

per-spih-KYOO-ih-teescripture

The clarity of Scripture. The claim that what a person needs for salvation is plain enough in the text to be understood without an authorized interpreter.

Traditions use it differently

A Reformation doctrine, and carefully limited even by those who hold it: the Westminster Confession says not all things are alike clear, and that the plain things are the main things. Catholic and Orthodox critics point at the number of Protestant denominations as evidence against it. Defenders reply that the core is agreed across all those denominations, and that the disputes are at the edges.

Predestination

pree-dess-tih-NAY-shunsalvation

That God determined beforehand who would be saved. What that determination rests on, and whether it can be resisted, is the argument.

You will hear it: Ephesians 1 and Romans 9 are where it is fought out.

Traditions use it differently

Calvinists hold election to be unconditional and grace finally irresistible; Arminians hold that God's choice takes foreseen faith into account and that grace can be refused; Lutherans affirm election to salvation but decline to teach a decree of reprobation.

Premillennialism

pree-mil-EN-ee-ul-izmlast things

That Christ returns before the thousand years of Revelation 20, which are a future reign on earth.

Revelation 20:1-6The millenniumSee also amillennialism

Presbyterian

prez-bih-TEER-ee-unchurch

Church government by elected elders sitting in graded courts, with no bishops. From the Greek for elder.

Roots: Greek presbyteros, elder.

You will hear it: Presbyterian and Reformed churches; also the name of the family itself.

Acts 15:6See also episcopal, congregational

Presbytery

PREZ-bih-treechurch

In Presbyterian government, the court above the local session and below the general assembly, made up of ministers and elders from a region.

1 Timothy 4:14See also presbyterian, synod

Prevenient grace

pre-VEEN-yentsalvation

Grace that comes before. The work God does in a person prior to any turning toward him, enabling a response that would otherwise be impossible.

Roots: Latin praevenire, to come before or go ahead of.

You will hear it: Central to Wesleyan and Arminian theology, which uses it to hold together real human choice and total dependence on grace.

Traditions use it differently

Everyone affirms that God moves first. The question is whether that first move can be finally resisted. Arminians say yes, which is what makes the choice real. Calvinists say the grace that saves is effectual, and distinguish it from a general grace that can be refused.

Prevenient grace

pree-VEEN-yentsalvation

Grace that goes ahead of us: God at work in a person before they are aware of it, making a free response possible.

Roots: Latin praevenire, to come before.

You will hear it: The Wesleyan answer to how free will and total inability fit together.

See also arminianism, grace

Priesthood of all believers

church

That every Christian has direct access to God and a priestly calling, without needing a human mediator besides Christ.

Traditions use it differently

A Reformation rallying cry, and frequently overread. Luther used it to deny a spiritual caste, not to abolish ordained ministry, which he continued to insist on. Catholic teaching affirms a common priesthood of the baptized alongside the ministerial priesthood, and Vatican II says they differ in kind and not only in degree.

1 Peter 2:9See also sacrament, ecclesiology

Propitiation

pro-pish-ee-AY-shunsalvation

A sacrifice that turns away wrath. In Christian usage, Christ's death dealing with the just anger of God against sin.

Roots: Latin propitiare, to appease. Translating the Greek hilasterion, the word used for the mercy seat on the ark.

You will hear it: In Romans 3 and 1 John. Some translations render the same word as expiation, meaning the removal of sin rather than the turning away of wrath, and the choice reflects a real theological disagreement.

Traditions use it differently

Whether the New Testament word carries the sense of appeasing wrath, or only of cleansing sin, has been argued since the mid twentieth century. Most evangelical translations use propitiation; several mainline ones use expiation or a phrase.

Providence

God

God's ongoing governance of creation and history, including through ordinary causes.

You will hear it: In discussions of suffering, of guidance, and of the book of Esther, where God is never named and providence is the whole point.

Pseudepigrapha

soo-deh-PIG-rah-fahscripture

Ancient Jewish and Christian writings attributed to figures who did not write them: 1 Enoch, Jubilees, the Testaments of the Twelve Patriarchs, and many more. Not the same as the deuterocanon.

You will hear it: Jude quotes 1 Enoch by name, which has occupied commentators ever since. The Ethiopian Orthodox Church includes Enoch and Jubilees in its canon, which is why its Bible is the largest in Christendom.

Purgatory

last things

In Catholic teaching, a state of purification after death for those who die in God's grace but are not yet fully purified.

Traditions use it differently

Catholic doctrine. Orthodoxy holds a different and less defined account of prayer for the dead. Protestant traditions reject it, and the sale of indulgences connected to it was the immediate trigger of the Reformation.

R

Rapture

last things

Believers being caught up to meet the Lord, from the Latin rapturo used to translate 1 Thessalonians 4:17.

Traditions use it differently

That believers meet the Lord is common ground. Whether that is a distinct event before a tribulation, as dispensational teaching holds, or another way of describing the second coming itself, as most other traditions hold, is the disagreement. The distinct pre-tribulation version dates from the nineteenth century.

1 Thessalonians 4:17

Real presence

church

That Christ is genuinely present in the Lord's Supper, not merely remembered. What genuinely means is the whole argument.

Traditions use it differently

Catholic teaching: transubstantiation, the substance changes while the appearances remain. Orthodoxy affirms the change and generally declines to explain the mechanism. Lutherans: Christ is truly present in, with, and under the bread and wine. Reformed: a true spiritual feeding on Christ by faith, with Calvin insisting this is no less real for being spiritual. Zwinglian and most Baptist practice: a memorial. This is one of the few places where the Reformation split among itself as sharply as it split from Rome.

Remonstrance

rih-MON-struncesalvation

The five articles published in 1610 by followers of Arminius objecting to strict predestination. The Synod of Dort answered with five points of its own.

You will hear it: The origin of the five points on both sides of the Calvinist-Arminian argument.

Repentance

salvation

A change of mind that turns into a change of direction. Not primarily feeling sorry.

Roots: Greek metanoia, literally a change of mind.

You will hear it: The first word of both John the Baptist's and Jesus' preaching.

Reprobation

rep-roh-BAY-shunsalvation

The counterpart of election: God's passing over, or decree concerning, those not chosen for salvation.

Traditions use it differently

Strict Calvinists teach a double decree, election and reprobation. Others hold single predestination, that God elects to save and simply leaves the rest to their choice. Lutherans affirm election and explicitly refuse to teach reprobation.

Resurrection

last things

Bodily rising from death. The Christian hope is not that you survive as a ghost but that God raises you, body and all, into a renewed creation.

You will hear it: In every creed, and argued at length in 1 Corinthians 15, where Paul insists that if there is no resurrection the whole message collapses.

Traditions use it differently

That the dead will be raised bodily is held by every historic tradition. What is argued is how resurrection relates to the soul: whether the soul is naturally immortal and waits consciously for its body, whether immortality is a gift given at the resurrection rather than a property we already own, or whether the dead rest unconscious until that morning. All three have long Christian histories.

S

Sacrament

church

A rite instituted by Christ that conveys or signifies grace. Augustine's phrase, a visible sign of an invisible grace, is still the usual starting point.

Traditions use it differently

Catholic and Orthodox traditions count seven. Most Protestants count two, baptism and the Lord's Supper, and many prefer the word ordinance to avoid implying that the rite itself conveys grace.

Sanctification

sank-tih-fih-KAY-shunsalvation

Being made holy over time. The lifelong process of actually becoming what God has declared you to be.

You will hear it: Usually paired with justification. A common summary: justification is a verdict, sanctification is a journey.

1 Thessalonians 4:3See also justification, theosis, concupiscence, union with christ

Schism

SIZ-um, or SKIZ-umchurch

A split in the church over authority or practice rather than over doctrine. Distinguished from heresy, which is a departure in belief.

Roots: Greek schisma, a tear or division.

You will hear it: The Great Schism of 1054 is the usual referent.

See also creed

Schism and heresy

church

Two different failures. Schism is breaking communion; heresy is teaching something the church has judged incompatible with the faith. A person can be one without being the other.

Traditions use it differently

Who is in schism from whom is exactly what the divisions are about, and every side of 1054 and 1517 has an account in which it stayed and the others left. Modern usage has softened: most traditions now speak of separated brethren rather than of heretics, and the Catholic and Orthodox mutual excommunications of 1054 were lifted in 1965.

Sensus plenior

SEN-sus PLEN-ee-orscripture

Fuller sense. A meaning God intended in a text that the human author did not fully grasp, usually invoked to explain how the New Testament reads the Old.

You will hear it: In every discussion of Matthew quoting Hosea 11:1, a verse about the exodus, and applying it to Jesus.

Traditions use it differently

Some hold that a text means what its author meant, full stop, and that the New Testament writers are drawing typological connections rather than uncovering hidden meanings. Others hold that divine authorship makes a fuller sense possible in principle. The practical stakes are high, since the answer governs whether readers today may find such meanings themselves.

Septuagint

SEP-too-uh-jintscripture

The ancient Greek translation of the Hebrew Scriptures, made from the third century BC onward. Abbreviated LXX.

Roots: Latin for seventy, from a tradition that seventy or seventy-two scholars produced it.

You will hear it: It matters because it is usually the version the New Testament writers quote, which is why a quotation sometimes does not match the Hebrew wording in your Old Testament.

Shekhinah

sheh-KEE-nahstudy

God's settled, visible presence dwelling with his people. The cloud on the tabernacle, the glory filling the temple.

Roots: Hebrew shakan, to dwell or settle. The noun itself is rabbinic rather than biblical, so the word will not be found in a concordance of the Old Testament, though the idea it names plainly is.

Traditions use it differently

Used freely across the traditions as shorthand. It is worth being precise that this is a later Jewish term adopted into Christian usage, not a biblical title, which matters when someone builds an argument on the word rather than on the passages.

Exodus 40:34-35See also tabernacle

Sheol, Hades, Gehenna

last things

Three different words that English Bibles have all rendered hell, which is the single largest source of confusion in this whole area. Sheol is the Hebrew grave or realm of the dead, where everyone goes. Hades is its Greek equivalent. Gehenna is a real valley outside Jerusalem, used by Jesus as an image of final destruction.

Roots: Gehenna transliterates ge-hinnom, the Valley of Hinnom, where children had been sacrificed under Ahaz and Manasseh and which later became a byword for defilement.

You will hear it: Anywhere someone argues about whether the Old Testament teaches hell. Much of that argument dissolves once you see that sheol is usually just the grave.

Traditions use it differently

Translators differ on whether to render these words or transliterate them. The King James uses hell for all three, which flattens a real distinction. Most modern translations keep them separate or footnote them.

Shunning

church

Withdrawing ordinary social contact from a member under discipline. Called the ban or Meidung among the Amish.

You will hear it: The strictness of its application is what divided the Amish from the Mennonites in 1693.

1 Corinthians 5:11

Sola scriptura

church

Scripture alone as the final authority. The Protestant formal principle.

Traditions use it differently

Widely misunderstood on both sides. The Reformers did not mean Scripture is the only authority, nor that creeds and councils are worthless, and they quoted the Fathers constantly. They meant Scripture is the only infallible norm, to which every other authority answers. The stronger position, that a Christian needs nothing but a Bible, is sometimes distinguished as solo scriptura and was not the Reformation's claim. Catholic and Orthodox critics reply that the canon itself was recognized by the church, so Scripture cannot be self-authenticating.

Soul

last things

In Scripture, most often the whole living person rather than a part of one. The Hebrew nephesh and the Greek psyche can mean life, breath, appetite, self, or creature, and are used of animals as well as of people.

Roots: Old English sawol, used to translate nephesh and psyche. The modern English sense of a detachable inner self owes as much to Plato as to either biblical language.

You will hear it: Wherever someone says save souls, or asks what happens to the soul at death.

Traditions use it differently

This is a live argument, and the vocabulary itself is part of it. Classical theology, Catholic, Orthodox, and much of Protestantism, teaches that God creates each soul immortal, so that it survives death consciously and is reunited with a raised body at the end. A second stream holds that immortality belongs to God alone and is given to us at the resurrection, so the soul is not naturally deathless. A third holds that the biblical writers are describing whole persons throughout, and that asking which part of you survives is asking a question the text does not ask. Genesis 2:7 is instructive: the man does not receive a soul, he becomes a living soul.

Supersessionism

study

The view that the church has replaced Israel as the people of God. Also called replacement theology, usually by people who reject it.

Traditions use it differently

The label is disputed by nearly everyone it is applied to. Most traditions historically taught some form of it. After the Holocaust, Catholic teaching in Nostra Aetate and much Protestant theology explicitly affirmed that God's covenant with the Jewish people has not been revoked, citing Romans 11:29. Where the argument now sits is over what that means concretely, not over whether antisemitism is compatible with the gospel, which no responsible body now defends.

Synod

SIN-udchurch

A formal assembly of church leaders that decides things. The word is used for both a one-off council and a permanent governing body.

Roots: Greek synodos, a coming together.

You will hear it: The Synod of Dort settled the Reformed answer to Arminianism; Lutheran bodies use it as a name, as in the Missouri Synod.

Systematic and biblical theology

study

Two ways of organizing the same material. Systematic theology arranges it by topic: what does the whole Bible teach about God, sin, salvation. Biblical theology follows the storyline, asking how a theme develops from Genesis forward.

You will hear it: In the titles of about half the books in any theological library.

T

Tabernacle

TAB-er-nak-ulstudy

The portable tent sanctuary Israel carried through the wilderness, and the pattern every later temple was built on. Also called the tent of meeting.

Roots: Latin tabernaculum, tent. The Hebrew mishkan is from a root meaning to dwell, and the related word shakan lies behind the later term Shekhinah for God's settled presence.

You will hear it: In Exodus, which gives its specification more space than it gives the creation of the world, and in Hebrews, which argues that it was a copy of something else.

Exodus 25:8-9See also most holy place, shekhinah

The descent into hell

Christ

The clause in the Apostles' Creed saying Christ descended. What it means has been read at least four ways: that he went to the realm of the dead, that he suffered hell's abandonment on the cross, that he preached to the dead, or that he simply died and was buried.

Roots: The Latin descendit ad inferos, to the lower places, which is not the same word as the place of punishment.

Traditions use it differently

Orthodoxy makes it the central Easter image: Christ shattering the gates and pulling Adam and Eve out by the wrists, which is what the Resurrection icon actually depicts. Catholic teaching holds he freed the righteous dead. Calvin read it as the cross's anguish. Some Reformed and evangelical churches omit the clause entirely.

Theodicy

thee-ODD-ih-seeGod

An attempt to justify the goodness of God given the existence of evil.

Roots: Coined by Leibniz in 1710, from Greek theos, God, and dike, justice.

You will hear it: In any serious conversation about suffering. Job is the Bible's own long engagement with the question, and notably it does not end with an explanation.

Theosis

THEH-oh-sissalvation

Deification, or divinization. The Orthodox account of salvation as genuine participation in the life of God, becoming by grace what God is by nature.

Roots: Greek theos, God. Athanasius: God became man so that man might become god, a line every Orthodox writer eventually quotes.

Traditions use it differently

Central and non-negotiable in Eastern Orthodoxy. Often misheard in the West as claiming we become gods, which it denies: the distinction between God's essence, which is unknowable, and his energies, which are shared, is the safeguard. Catholic theology has a real equivalent in sanctifying grace and the beatific vision. Protestants have recently rediscovered it, and there is a body of work arguing Luther taught something close to it.

Total depravity

salvation

Not that people are as bad as they could be, but that no part of a person is untouched by sin, including the will and the mind. The word total describes the extent of the damage, not its intensity.

You will hear it: The T in the TULIP acronym for the five points of Calvinism.

Traditions use it differently

Reformed and Lutheran theology affirm it strongly. Arminian theology also affirms it, then adds prevenient grace, which restores enough freedom to respond. That is the actual difference, and it is smaller than the shouting suggests. Catholic and Orthodox theology describe a wounded rather than wholly incapacitated nature.

Transubstantiation

tran-sub-stan-she-AY-shunchurch

The Catholic teaching that at communion the bread and wine become the body and blood of Christ in substance, while the appearances of bread and wine remain.

Roots: Latin, a change of substance. The vocabulary is borrowed from Aristotle.

Traditions use it differently

Lutherans affirm a real presence without adopting this explanation; Reformed churches hold Christ is present spiritually and received by faith; most Baptists and others hold the meal to be a memorial.

Trinity

God

One God in three persons: Father, Son, and Holy Spirit. Not three gods, and not one person wearing three masks.

Roots: Latin trinitas, coined by Tertullian around AD 200. The word is not in the Bible; the doctrine is the church's summary of what the Bible says.

You will hear it: In every historic creed. The two errors it rules out are tritheism, three gods, and modalism, one person appearing in three modes.

Typology

study

Reading an earlier person, event, or institution as a pattern that anticipates a later fulfillment. Passover as a type of the cross, for example.

Traditions use it differently

Everyone agrees the New Testament does this. How far a modern reader may extend the practice without inventing connections is genuinely argued.

U

Union with Christ

salvation

The New Testament's most frequent way of describing a Christian: someone who is in Christ. Paul uses the phrase or its equivalents more than 150 times, and it is the root from which justification, sanctification, and adoption all grow.

You will hear it: Everywhere in Paul, and increasingly in preaching that wants to get past a merely transactional account of salvation.

Traditions use it differently

Traditions weight it differently. Eastern Orthodoxy makes participation in God the whole point and calls it theosis. Calvin made union the organizing idea of his soteriology, which is often forgotten by his heirs. Lutheran theology has worried that emphasizing union can blur the sharp exteriority of justification.

Galatians 2:20See also theosis, justification, adoption

Universal reconciliation

last things

The hope, or in stronger forms the claim, that God will finally save everyone. Distinguished from the idea that all religions lead to God, which is a different question.

Roots: Sometimes called apokatastasis, Greek for restoration, from Acts 3:21.

Traditions use it differently

Held by Origen and Gregory of Nyssa in the early church, which is why it cannot be dismissed as modern. The Second Council of Constantinople in 553 condemned a form of it, and Catholic, Orthodox, and Protestant teaching have overwhelmingly rejected it since. Modern versions are usually stated as hope rather than certainty, as with Hans Urs von Balthasar, who argued Christians may hope that all are saved without claiming to know it.

V

Vulgate

scripture

Jerome's Latin translation, made from the late fourth century, which was the Bible of the Western church for over a thousand years.

Roots: Latin vulgata, the common version, because it was in the ordinary language of its readers, which is worth remembering before dismissing vernacular translation.

You will hear it: Behind much English theological vocabulary, since words like justification, sanctification, and propitiation all come to us through Latin rather than directly from Greek.

Several of these words name whole arguments. The ones Christians answer differently have their own articles →
