Remigius of Auxerre
Catena Aurea · Matthäusevangelium 3
Then cometh Jesus from Galilee to Jordan unto John, to be baptized of him. But John forbad Him, saying, I have need to be baptized of Thee, and comest Thou to me? And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered Him.
Or thus; It becometh us to fulfil all righteousness, that is, to give an example of perfect justification in baptism, without which the gate of the kingdom of heaven is not opened. Hence let the proud take an example of humility, and not scorn to be baptized by My humble members when they see Me baptized by John My servant. That is true humility which obedience accompanies; as it continues, then he suffered Him, that is, at last consented to baptize Him.
