Mark 14:23-25

V. 23. And He took the cup, and when He had given thanks, He gave it to them; and they all drank of it. V. 24. And He said unto them, This is My blood of the new testament, which is shed for many. V. 25. Verily I say unto you, I will drink no more of the fruit of the vine until that day that I drink it new in the kingdom of God.

He stated that the bread which He gave to them is His body.

Then He took the cup which I they had used during the meal, the third cup being known as the cup of blessing. Having given thanks to God over it, He gave it to them, passing from one to the other. And again He made a very clear statement regarding the contents of that cup: This is My blood of the covenant, which is poured out for many.

It is the New Testament which was herewith ushered in; the covenant which God makes with the world in and with Christ and His blood and through its shedding has brought salvation to all men, even though only a part of mankind will accept the offering of their redemption through the blood of Jesus. If we believe the words of Christ just as they were here spoken, taking our reason captive under the obedience of Scriptures, we shall always receive the full benefit of this Sacrament. We shall always take from it the assurance of the forgiveness of all our sins. We shall always be strengthened anew in our faith.

As the celebration of the first Passover strengthened the Israelites for their long journey through the wilderness, so the Lord's Supper is for the believers of the New Testament food on the way during their earthly pilgrimage. And incidentally, like the paschal meal, it points forward to the end of the journey, to the heavenly banquet, where the Lord will drink with us of the cup of salvation in all eternity.

To this the Lord refers when He says that He will henceforth not drink with them of the fruit of the vine. For this expression was the term by which the paschal wine was designated among the Jews, the term which they used in the blessing of, and in the thanksgiving over, the wine.

To argue that the Lord had used anything but true, fermented wine in the institution of the Eucharist, is to overthrow all historical and exegetical reasoning. Compare Matt. 26, 29. The Lord here instituted the second Sacrament of the New Testament.

"As in Baptism He loosed from the Old Testament circumcision the sacred washing which accompanied it, and made it the New Testament Sacrament of the covenant entered into, so also now He severed the breaking of the bread and the cup of thanksgiving from the Old Testament Passover, and made it a sacrament of the New Testament redemption" (Schaff, Commentary, Matthew, 469).
