Mateus 3

Mateus 3:13

[(as quoted by Jerome, AD 420)] Behold, the mother of our Lord and His brethren said to Him, John Baptist baptizes for the remission of sins; let us go and be baptized by him. But He said to them, what sin have I committed that I should go and be baptized by him? Unless, haply, the very words which I have said are only ignorance. — Against the Pelagians (Book III), Section 2
