BLB(i)
26 For as often as you may eat this bread and may drink the cup, you proclaim the Lord’s death until He should come.
27 Therefore whoever should eat the bread or should drink the cup of the Lord unworthily will be guilty of the body and of the blood of the Lord.
28 But let a man examine himself, and in this manner let him eat of the bread, and let him drink of the cup.
