Question 75: How does the Lord’s Supper signify and seal to you that you share in Christ’s one sacrifice on the cross and in all His gifts?
Answer: In this way: Christ has commanded me and all believers to eat of this broken bread and drink of this cup in remembrance of Him. With this command He gave these promises: First, as surely as I see with my eyes the bread of the Lord broken for me and the cup given to me, so surely was His body offered for me and His blood poured out for me on the cross. Second, as surely as I receive from the hand of the minister and taste with my mouth the bread and the cup of the Lord as sure signs of Christ’s body and blood, so surely does He Himself nourish and refresh my soul to everlasting life with His crucified body and shed blood. (Matt. 26:26-28; Mark 14:22-24; Luke 22:19, 20; I Cor. 11:23-25)
