Origen — as excerpted in the Catena Aurea on John 13:6-11

“Let those who refuse to allegorize these and like passages, say how it is probable that he who out of reverence for Jesus said, Thou shalt never wash my feet, would have had no part with the Son of God; as if not having his feet washed was a deadly wickedness. Wherefore it is our feet, i. e. the affections of our mind, that are to be given up to Jesus to be washed, that our feet may be beautiful; especially if we emulate higher gifts, and wish to be numbered with those who preach glad tidings.”
