Nor is there need of very many arguments, dearest brother, to prove that baptism is always indicated by the appellation of water, and that thus we ought to understand it, since the Lord, when He came, manifested the truth of baptism and the cup in commanding that that faithful water, the water of life eternal, should be given to believers in baptism, but, teaching by the example of His own authority, that the cup should be mingled with a union of wine and water. For, taking the cup on the eve of His passion, He blessed it, and gave it to His disciples, saying, "Drink ye all of this; for this is my blood of the New Testament, which shall be shed for many, for the remission of sins. I say unto you, I will not drink henceforth of this fruit of the vine, until that day in which I shall drink new wine with you in the kingdom of my Father." In which portion we find that the cup which the Lord offered was mixed, and that that was wine which He called His blood. Whence it appears that the blood of Christ is not offered if there be no wine in the cup, nor the Lord's sacrifice celebrated with a legitimate consecration unless our oblation and sacrifice respond to His passion. But how shall we drink the new wine of the fruit of the vine with Christ in the kingdom of His Father, if in the sacrifice of God the Father and of Christ we do not offer wine, nor mix the cup of the Lord by the Lord's own tradition?
