1 Corinthians 11:26-28

New International Version

²⁶ For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes.^(A)

²⁷ So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord.^{(B) 28} Everyone ought to examine themselves^(C) before they eat of the bread and drink from the cup.
