Chapter 29 summarizes Presbyterian beliefs about the Lord's Supper. It states that the sacrament is to be observed in the church until 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."
