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.

But if a good meaning is to be here attached to the dipping, his ingratitude for that good was deservedly followed by damnation.
