Then came he to Simon Peter: and Peter said unto him, Lord, do you wash my feet?
All Commentaries on John 13:6 Go To John 13
John Chrysostom
AD 407
Though Peter was the first of the Apostles, yet it is possible that the traitor petulantly placed himself above him; and that this may be the reason why our Lord first began to wash, and then comes to Peter.
Some one will ask why none of them prevented Him, except Peter, this being a sign not of want of love, but of reverence. The reason seems to be, that He washed the traitor first, and came next to Peter, and that the other disciples were checked by the reply to Peter. Any of the rest would have said what Peter did, had his turn come first.
i.e. How useful a lesson of humility it teaches you, and how, directly this virtue leads to God.
He does not say on what account He performs this act of washing, but only threatens him. For Peter was not persuaded by the first answer: you shall know hereafter he did not say, Teach me then that I may submit. But when he was threatened with separation from Christ, then he submitted.
Or thus: When He calls them clean, you must not suppose that they were delivered from sin before the victim was offered. He means cleanness in respect of knowledge; for they were now delivered from Jewish error.
