WLC Q.168: What is the Lord’s supper?
The Lord’s supper is a sacrament of the New Testament, (Luke 22:20) wherein, by giving and receiving bread and wine according to the appointment of Jesus Christ, his death is shewed forth; and they that worthily communicate feed upon his body and blood, to their spiritual nourishment and growth in grace; (Matt. 26:26–28, 1 Cor. 11:23–26) have their union and communion with him confirmed; (1 Cor. 10:16) testify and renew their thankfulness, (1 Cor. 11:24) and engagement to God, (1 Cor. 10:14–16,21) and their mutual love and fellowship each with the other, as members of the same mystical body. (1 Cor. 10:17)
Our Lord Jesus, in the night wherein He was betrayed, instituted the sacrament of His body and blood, called the Lord’s Supper, to be observed in His Church, unto the end of the world, for the perpetual remembrance of the sacrifice of Himself in His death; the sealing all benefits thereof unto true believers, their spiritual nourishment and growth in Him, their further engagement in and to all duties which they owe unto Him; and, to be a bond and pledge of their communion with Him, and with each other, as members of His mystical body. (1 Cor. 11:23–26, 1 Cor. 10:16–17,21, 1 Cor. 12:13)
