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

“Jesus was unwilling to wash hands, and despised what was said of Him in this respect: Thy disciples wash not their hands when they eat bread. (Matt. 15:2) And He did not wish the head to be submerged, in which was apparent the image and glory of the Father; it was enough for Him that the feet were given Him to wash: Jesus answered and said, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.”
