Origen
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.
(t. xxxii. 2.) Mystically, dinner is the first meal, taken early in the spiritual day, and adapted to those who have just entered upon this day. Supper is the last meal, and is set before those who are farther advanced. According to another sense, dinner is the understanding of the Old Testament, the supper the understanding the mysteries hid in the New. Yet even they who sup with Jesus, who partake of the final meal, need a certain washing, not indeed of the top parts of their body, i. e. the soul, but its lower parts and extremities, which cleave necessarily to earth. (c. 4.). It is, And began to wash; for He did not finish His washing till afterwards. The feet of the Apostles were defiled now: All of ye shall be offended because of Me this night. (Matt. 26:31) But afterwards He cleansed them, so that they needed no more cleansing.
