Augustine of Hippo
Catena Aurea · Johannesevangelium 13
Now before the feast of the passover, when Jesus knew that his hour was come that he should depart out of this world unto the Father, having loved his own which were in the world, he loved them unto the end. And supper being ended, the devil having now put into the heart of Judas Iscariot, Simon’s son, to betray him; Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God; He riseth from supper, and laid aside his garments; and took a towel, and girded himself. After that he poureth water into a bason, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded.
(Tr. lv. 7) He laid aside His garments, when, being in the form of God, He emptied Himself; He girded. Himself with a towel, took upon Him the form of a servant; He poured water into a bason, out of which He washed His disciples’ feet. He shed His blood on the earth, with which He washed away the filth of their sins; He wiped them with the towel wherewith He was girded; with the flesh wherewith He was clothed, He established the steps of the Evangelists; He laid aside His garments, to gird Himself with the towel; that He might take upon Him the form of a servant, He emptied Himself, not laying aside indeed what He had, but assuming what He had not. Before He was crucified, He was stripped of His garments, and when dead was wound up in linena clothes: the whole of His passion is our cleansing.
