For this is my blood of the new covenant, which is shed for many for the remission of sins.
All Commentaries on Matthew 26:28 Go To Matthew 26
John Chrysostom
AD 407
And how were they not confounded at hearing this? Because He had before told unto them many and great things touching this. Wherefore that He establishes no more, for they had heard it sufficiently, but he speaks of the cause of His passion, namely, the taking away of sins. And He calls it blood of a New Testament, that of the undertaking, the promise, the new law. For this He undertook also of old, and this comprises the Testament that is in the new law. And like as the Old Testament had sheep and bullocks, so this has the Lord's blood. Hence also He shows that He is soon to die, wherefore also He made mention of a Testament, and He reminds them also of the former Testament, for that also was dedicated with blood. And again He tells the cause of His death, which is shed for many for the remission of sins; and He says, Do this in remembrance of me. Do you see how He removes and draws them off from Jewish customs. For like as you did that, He says, in remembrance of the miracles in Egypt, so do this likewise in remembrance of me. That was shed for the preservation of the firstborn, this for the remission of the sins of the whole world. For, This, says He, is my blood, which is shed for the remission of sins.
But this He said, indicating thereby, that His passion and His cross are a mystery, by this too again comforting His disciples. And like as Moses says, This shall be to you for an everlasting memorial, Exodus 12:14 so He too, in remembrance of me, until I come. Therefore also He says, With desire I have desired to eat this passover, Luke 22:15 that is, to deliver you the new rites, and to give a passover, by which I am to make you spiritual.
And He Himself drank of it. For lest on hearing this, they should say, What then? Do we drink blood, and eat flesh? And then be perplexed (for when He began to discourse concerning these things, even at the very sayings many were offended), therefore lest they should be troubled then likewise, He first did this Himself, leading them to the calm participation of the mysteries. Therefore He Himself drank His own blood. What then must we observe that other ancient rite also? Some one may say. By no means. For on this account He said, Do this, that He might withdraw them from the other. For if this works remission of sins, as it surely does work it, the other is now superfluous.
As then in the case of the Jews, so here also He has bound up the memorial of the benefit with the mystery, by this again stopping the mouths of heretics. For when they say, Whence is it manifest that Christ was sacrificed? Together with the other arguments we stop their mouths from the mysteries also. For if Jesus did not die, of what are the rites the symbols?
