1 Corinthians 11 v 23-24


1 Corinthians 11:23-24 
(23)  For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: 
(24)  And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. 


11:23-24. Paul proceeded to remind the Corinthians of what they knew but had denied by their actions. Whether this teaching came to Paul directly (by a vision; cf. Gal. 1:12) or indirectly (by men; 1 Cor. 15:1), it came with the Lord’s authority. The bread represented the incarnate body of Christ unselfishly assumed (Phil. 2:6-7) and unselfishly given on the cross for the benefit of others (2 Cor. 8:9; Phil. 2:8), that kept needing to be remembered (cf. 1 Cor. 4:8-13).
