The Bible says: “The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ?” (I Corinthians 10:16)
Luther explains: “What is the benefit of this eating and drinking? These words, ‘Given and shed for you for the forgiveness of sins,’ show us 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.”
Salvageable adds: If the bread were merely a reminder of Christ’s body and the wine a reminder of Christ’s blood, then eating and drinking the Lord’s Supper would be something we do for Jesus, a way to show that we remember him. Indeed, many Protestant Christians focus on the words, “Do this in remembrance of me,” and they consider the Lord’s Supper a work they do for Jesus. Luther and Lutherans focus on the words, “Given and shed for you for the forgiveness of sins.” They focus also on Paul’s word, “participation”—also translated as communication, fellowship, or communion. We participate with people, not with pictures. We have fellowship with people, not with reminders. In Holy Communion, our link is to Jesus himself, not to reminders of what Jesus did.
Jesus said, “Do this in remembrance of me,” wanting us to remember him every time we eat and drink the Sacrament. Otherwise, we are just going through the motions of religion. God hates seeing his people going through the motions of religion. He disparaged the sacrifices offered in the Old Testament, even though he had commanded those sacrifices. He spoke bitterly about those sacrifices because his people were going through the motions of religion without faith in God and his promises. Likewise, Jesus wants people to eat and drink the sacrament thinking about him, believing his promises, and claiming what he offers—namely, the forgiveness of sins.
Even though we are Christians, we sin often. We need forgiveness often. We repent daily, renewing the relationship established with God through Holy Baptism. We confess often, hearing the absolution and being assured that all our sins are forgiven. We receive Holy Communion often, coming as close to Jesus as is possible before the new creation, since he says that his body and his blood are truly present when we eat and drink at his Table.
“Where there is forgiveness of sins,” Luther says, “there is also life and salvation.” The three come as a package. We cannot have eternal life without the forgiveness of our sins. We cannot be rescued from sin and from all our enemies without the forgiveness of our sins. But when our sins are forgiven, eternal life is guaranteed to us and we share Christ’s victory over all our enemies.
