The Lord was Baptized, not to be cleansed Himself, but to cleanse the waters, so that those waters, cleansed by the flesh of Christ which knew no sin, might have the power of Baptism.

Blessed, plainly, is that life which is not valued at the estimation of outsiders, but is known, as judge of itself, by its own inner feelings. It needs no popular opinions as its reward in any way; nor has it any fear of punishments. Thus the less it strives for glory, the more it rises above it. For to those who seek for glory, that reward in the shape of present things is but a shadow of future ones, and is a hindrance to eternal life, as it is written in the Scriptures: 'Truly I say to you, they have received their reward'

For you read that he said: 'God, Who knows the hearts of men, bore witness, giving them the Holy Spirit, even as was given to us; and He made no distinction between us and them, purifying their hearts by faith' (Acts 15:8-9). In which is to be considered, that as Christ is the Cornerstone, Who joined together both peoples into one, so, too, the Holy Spirit made no distinction between the hearts of each people, but united them.
