Bishop of Lyon

Irenaeus was born in Asia Minor, and became bishop of Lyon. St.Irenaeus is know as the father of catholic dogma.

He denounced the Gnostics and supported the primacy of the bishop of Rome. Against the Gnostics (dualistic sects that maintained that salvation is not from faith but from some esoteric knowledge) Irenaeus urged that Catholic teaching was verified because a continuous succession of teachers, beginning with the Apostles, could be demonstrated.
