Verified Claim · Ecclesiology
Irenaeus, Tertullian, and Clement of Alexandria all appeal to apostolic succession — the publicly known chain of bishops from the apostles — as the decisive test of orthodoxy against heretics who claimed secret apostolic traditions.
The doctrine of apostolic succession is not primarily about the validity of ordination — it is about the transmission of teaching. The early Fathers’s argument was epistemological: we know what the apostles taught because we can trace the public chain of those who received it from them. Anyone who claims a different teaching must show their chain of transmission.

Apostolic succession solves an epistemological problem: how do we know what the apostles taught? The Gnostics claimed secret traditions. The orthodox answer was: here is the public chain of those who received the teaching from the apostles and passed it on. The chain is verifiable. The Gnostics cannot produce one. The test is simple and decisive.
