Bishops, in succession
Authority runs through bishops who stand in continuity with the apostles, and who ordain, teach, and guard the unity of the church.
What it claims
This is the structure the church actually had as soon as we can see it. Ignatius of Antioch, writing around AD 110 within living memory of the apostles, assumes a bishop in every church and treats it as unremarkable. The New Testament shows the pattern forming: apostles appoint, Timothy and Titus are left with authority to appoint elders and correct churches, and the Jerusalem council decides for congregations that were not present. Someone has to be able to say what the church teaches, or every congregation becomes its own denomination within a generation. Succession is not magic. It is accountability with a memory.
Who holds it
, , Anglican, and most Methodist and Lutheran churches. Between them, the large majority of Christians in the world.
The texts it stands on
- Titus 1:5 Left in Crete to appoint elders in every town, which is authority over multiple congregations
- Acts 15:22-29 A council binding churches that were not in the room
- 1 Timothy 5:19-22 Timothy receives charges against elders and lays on hands, which is oversight
- 2 Timothy 2:2 Entrust to faithful men who will be able to teach others, a chain of transmission
Strongest case
It has by far the best historical claim, since it is demonstrably what the church looked like within a generation of the apostles and remained for fifteen centuries. It also solves the problem of doctrinal drift better than the alternatives, and its critics tend to concede this while objecting on other grounds.
Hardest question
Concentrated authority has been catastrophically abused, and the abuse scandals of recent decades are structural as much as personal, since the same office investigated itself. The New Testament also uses elder and overseer interchangeably, which suggests a plurality of elders rather than one bishop over them, and the monarchical bishop looks like a development rather than an institution.
How it answers that
The abuse charge is granted without qualification and has been addressed by these churches with public admissions of failure. The structural response is that oversight failed, not that oversight is wrong, and a church with an abusive pastor has fewer remedies rather than more, since there is nobody above him. On the vocabulary, the position agrees the terms overlap in the New Testament and says the office differentiated as the apostles died, which is exactly what you would expect and exactly what Ignatius describes so early that a long development is not available.
