“(Ambrosiaster. Serm. xii. 4.) For, as we have said, when the Saviour was washed, then the water was cleansed for our baptism, that a laver might be ministered to the people who were to come. Moreover, it behoved that in Christ’s baptism should be signified those things which the faithful obtain by baptism.”
