So, in the discussion recorded in John 6:52-65, Jesus was not talking about the world of mankind as the ones to drink his blood as well as eating his flesh, figuratively, during his millennial reign. He was talking about believers whom he would bring into the new covenant. (Jer. 31:31-34; Rev. 20:4-6) These would become spiritual Israelites. That is why, when Jesus inaugurated the “Lord’s evening meal,” he said to his Israelite apostles: “This cup means the new covenant by virtue of my blood, which is to be poured out in your behalf.” (Luke 22:20; 1 Cor. 11:20, 25) Or, according to Matthew 26:27: “Drink out of it, all of you; for this means my ‘blood of the covenant,’ which is to be poured out in behalf of many for forgiveness of sins.” The 11 faithful apostles who accepted the unleavened bread and the cup of wine at Jesus’ hands that Passover night of 33 C.E. were taken into the new covenant on the day of Pentecost, the fifty-second day from the Passover.

So, too, at the Memorial the cup of wine that symbolizes the “blood of the covenant” is spoken of as “the cup of Jehovah.” When the spiritual Israelites drink from this cup, they become sharers with Jehovah respecting Christ’s blood that validates the new covenant. By this gesture the spiritual Israelites show that they worship Jehovah as their God and do not idolize any demon as god. Jehovah accepts Christ’s blood as that which puts the new covenant in force. Likewise the drinkers of the Memorial cup accept Christ’s blood as the life that he poured out in sacrifice for them to get God’s forgiveness of sins through that covenant.
