1 Corinthians 10:16-18

WNT(i) 16 The cup of blessing, which we bless, does it not mean a joint-participation in the blood of Christ? The loaf of bread which we break, does it not mean a joint-participation in the body of Christ? 17 Since there is one loaf, we who are many are one body; we, all of us, share in that one loaf. 18 Look at the Israelites--the nation and their ritual. Are not those who eat the sacrifices joint-partakers in the altar?
