[Naaman] dipped himself," it says, "seven times in Jordan." It was not for nothing that Naaman of old, when suffering from leprosy, was purified upon his being baptized, but as an indication to us.

Irenaeus of LyonsThe glory of God is a human being fully alive; and to be alive consists in beholding God.
Irenaeus of LyonsIt is not necessary to seek the truth among others which it is easy to obtain from the Church; since the apostles, like a rich man [depositing his money] in a bank, lodged in her hands most copiously all things pertaining to the truth.
Irenaeus of LyonsHe [Jesus] fought and conquered. On the one hand, he was man who struggled for his fathers and through his obedience cancelled their disobedience. On the other hand, he bound the strong one and freed the weak and bestowed salvation on his handiwork by abolishing sin. For he is our compassionate and merciful Lord who loves mankind ... Had not man conquered man's adversary, the enemy would not have been conquered justly. Again, had it not been God who bestowed salvation we would not possess it securely.
Irenaeus of LyonsHe who was the Son of God became the Son of man, that man ... might become the son of God.
Irenaeus of Lyons
