1 Corinthians 11:23-29
For I received from the Lord what I also handed on to
you, that the Lord Jesus, on the night he was handed
over, took bread, and, after he had given thanks, broke
it and said, "This is my body that is for you. Do this in
remembrance of me." 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." For as often as you eat this
bread
and drink the cup, you proclaim the death of the Lord
until he comes. Therefore whoever eats the bread or
drinks the cup of the Lord unworthily will have to answer
for the body and blood of the Lord. A person should
examine himself, and so eat the bread and drink the
cup. For anyone who eats and drinks without discerning
the body, eats and drinks judgment on himself.
