because we are commanded only to drink the blood of our Lord.
1 Corinthians 10:16
the cup of blessing which we bless, is it not a participation in the BLOOD OF CHRIST?
Catholics have answered this question “yes” for 2,000 years.
I guess there are some who would answer Paul “No, it only REPRESENTS the blood of Christ”.
Do you know and understand the story to which I am referring?
Did He call it THE BLOOD OF CHRIST...No ..."The cup of blessing—answering to the Jewish "cup of blessing," over which thanks were offered in the Passover. It was in doing so that Christ instituted this part of the Lord's Supper (Mt 26:27; Lu 22:17, 20)
we bless—"we," not merely ministers, but also the congregation. The minister "blesses" (that is, consecrates with blessing) the cup, not by any priestly transmitted authority of his own, but as representative of the congregation, who virtually through him bless the cup.".Jamieson-Fausset-Brown Bible Commentary
Paul called it "the cup" (as did Jesus..) and he called it bread (as dd Jesus)
