Q.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?
A. 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:1 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.
Q.What does it mean to eat the crucified body of Christ and to drink His shed blood?
A. First, to accept with a believing heart all the suffering and the death of Christ, and so receive forgiveness of sins and life eternal.1 Second, to be united more and more to His sacred body through the Holy Spirit, who lives both in Christ and in us.2 Therefore, although Christ is in heaven3 and we are on earth, yet we are flesh of His flesh and bone of His bones,4 and we forever live and are governed by one Spirit, as the members of our body are by one soul.5
Q.Where has Christ promised that He will nourish and refresh believers with His body and blood as surely as they eat of this broken bread and drink of this cup?
In the institution of the Lord’s supper:
The Lord Jesus, on the night He was betrayed,
took bread, and when He had given thanks,
He broke it and said,
“This is My body, which is for you;
Do this in remembrance of Me.”
In the same way, after supper He took the cup, saying,
“This cup is the new covenant in My blood;
Do this, whenever you drink it,
in remembrance of Me.”
For whenever you eat this bread and drink this cup,
you proclaim the Lord’s death
until He comes (1 Corinthians 11:23-26).
This promise is repeated by Paul where he says:
Is not the cup of thanksgiving for which we give thanks
a participation in the blood of Christ?
And is not the bread that we break
a participation in the body of Christ?
Because there is one loaf,
we, who are many, are one body,
for we all partake of the one loaf (1 Corinthians 10:16, 17).
