John Chrysostom (attributed)

In this he shews that Christ after this baptized John; which is expressly told in some apocryphal booksi. Suffer now that I fulfil the righteousness of baptism in deed, and not only in word; first submitting to it, and then preaching it; for so it becometh us to fulfil all righteousness. Not that by being baptized He fulfils all righteousness, but so, in the same manner, that is, as He first fulfilled the righteousness of baptism by His deeds, and after preached it, so He might all other righteousness, according to that of the Acts, All things that Jesus began both to do and to teach. (Acts 1:1.) Or thus, all righteousness, according to the ordinance of human nature; as He had before fulfilled the righteousness of birth, growth, and the like.
