The Lord's Supper — 1 Corinthians 11:23-26

1Cor 11:23-26 hands on the words of institution: "this is my body... this cup is the new covenant in my blood... do this in remembrance of me." The meal proclaims the Lord's death "until he comes."

Thomas Aquinas — Summa Theologiae, which John Calvin — Institutes of the Christian Religion. Catholic Church — Catechism of the Catholic Church. The Supper has been the central sacramental dividing line of the church.

The "new covenant in my blood" fulfills Jer 31:31 and the Passover of Exod 12:23. The shared loaf expresses the one body of 1Cor 12:12.
