1 Corinthians 11:25-27

Revised Standard Version Catholic Edition

²⁵ In the same way also the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” ²⁶ For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.

Partaking of the Supper Unworthily

²⁷ Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord.
