1 Corinthians 11:25

²⁰Likewise, he took the cup after supper, saying, “This cup is the new covenant in my blood, which is poured out for you.

¹⁵For this reason he is the mediator of a new covenant, since a death has occurred for the redemption of the transgressions that were under the first covenant, that those who have been called may receive the promise of the eternal inheritance. ¹⁶For where a last will and testament is, there must of necessity be the death of him who made it. ¹⁷For a will is in force where there has been death, for it is never in force while he who made it lives. ¹⁸Therefore even the first covenant has not been dedicated without blood. ¹⁹For when every commandment had been spoken by Moses to all the people according to the law, he took the blood of the calves and the goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, ²⁰saying, “This is the blood of the covenant which God has commanded you.”

²⁰Now may the God of peace, who brought again from the dead the great shepherd of the sheep with the blood of an eternal covenant, our Lord Jesus,

⁶who also made us sufficient as servants of a new covenant, not of the letter but of the Spirit. For the letter kills, but the Spirit gives life.

¹⁴But their minds were hardened, for until this very day at the reading of the old covenant the same veil remains, because in Christ it passes away.

¹⁶The cup of blessing which we bless, isn’t it a sharing of the blood of Christ? The bread which we break, isn’t it a sharing of the body of Christ?

²⁷Therefore whoever eats this bread or drinks the Lord’s cup in a way unworthy of the Lord will be guilty of the body and the blood of the Lord. ²⁸But let a man examine himself, and so let him eat of the bread and drink of the cup.
