Someone might ask, “Why would a holy man desire baptism?” Listen to the answer: Christ is baptized, not to be made holy by the water, but to make the water holy, and by his cleansing to purify the waters which he touched. For the consecration of Christ involves a more significant consecration of the water.
For when the Savior is washed, all water for our baptism is made clean, purified at its source for the dispensing of baptismal grace to the people of future ages. Christ is the first to be baptized, then, so that Christians will follow after him with confidence. (St Maximus of Turin 423 AD).
