Irenaeus' Refutation

Irenaeus is relatively brief in his refutation of his opponents. Basically:

(1) He questions their hermeneutic, applying it to Homer to show what ridiculous results could be reached.
(2) He also refers to the apostolic tradition, the faith he claims is common to all churches of his time in all languages.
(3) In Irenaeus, although he does not use this terminology, we see a distinction made between the faith, which is considered unique, and its formulations, which may vary according to the skills and the approach of different theologians.
