Paedobaptism
PEE-doh-bap-tizmchurchThe 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 thingsThe 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-kutchurchThe office and territory of a patriarch, the senior bishop of one of the ancient sees: Rome, Constantinople, Alexandria, Antioch and Jerusalem.
Patristics
studyThe 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
salvationThe 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-sisGodThe 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.
Perseverance of the saints
salvationThe 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-teescriptureThe 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-shunsalvationThat 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 thingsThat Christ returns before the thousand years of Revelation 20, which are a future reign on earth.
Presbyterian
prez-bih-TEER-ee-unchurchChurch 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.
Presbytery
PREZ-bih-treechurchIn Presbyterian government, the court above the local session and below the general assembly, made up of ministers and elders from a region.
Preterist
PRET-er-istlast thingsThe reading that most or all of Revelation's prophecy was fulfilled in the first century, chiefly in the fall of Jerusalem in AD 70.
Roots: Latin praeter, past.
Prevenient grace
pre-VEEN-yentsalvationGrace 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-yentsalvationGrace 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.
Priesthood of all believers
churchThat 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.
Propitiation
pro-pish-ee-AY-shunsalvationA 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
GodGod'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-fahscriptureAncient 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 thingsIn 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.
