The Lord’s Supper, also called Holy Communion or the Sacrament of the Altar, is the true body and blood of our Lord Jesus Christ, under the bread and wine, instituted by Christ himself, for us Christians to eat and to drink. The benefit which we receive from such eating and drinking is shown us by these words: “Given and shed for you for the remission of sins,” namely, that in the Sacrament forgiveness of sins, life and salvation are given us through these words. For where there is forgiveness of sins, there is also life and salvation.
We believe that all who join in the Sacrament of the Lord’s Supper receive the true body and blood of Christ in, with, and under the bread and wine (1 Corinthians 10:16). This is true because, when the Lord instituted this sacrament, he said, “This is my body. This is my blood of the covenant, which is poured out for many for the forgiveness of sins” (Matthew 26:26,28). We believe that Christ’s words of institution cause the real presence—not any human action. As believers receive his body and blood, they also receive the forgiveness of sins (Matthew 26:28) and the comfort and assurance that they are truly his own. Unbelievers also receive Christ’s body and blood, but to their judgment (1 Corinthians 11:29).
