Tractates on the Gospel of John

³ But it was not then, as some thoughtless readers suppose, that Judas received the body of Christ. For we are to understand that the Lord had already dispensed to all of them the sacrament of His body and blood, when Judas also was present, as very clearly related by Saint Luke; and it was after this that we come to the moment when, in accordance with John's account, the Lord made a full disclosure of His betrayer by dipping and holding out to him the morsel of bread, and intimating perhaps by the dipping of the bread the false pretensions of the other. For the dipping of a thing does not always imply its washing; but some things are dipped in order to be dyed. But if a good meaning is to be here attached to the dipping, his ingratitude for that good was deservedly followed by damnation.
