How can bodily eating and drinking do such great things? Certainly not just eating and drinking do these things, but the words written here: "Given and shed for you for the forgiveness of sins." These words, along with the bodily eating and drinking, are the main thing in the Sacrament. Whoever believes these words has exactly what they say: "forgiveness of sins." (Small Catechism)
In the Name + of Jesus. Amen. Whether your parents have a good reason or not for telling you to do something, they can usually justify it with these words: “Because I said so.” Those words mean there aren't any questions to be asked and answered. Something is the way it is because your parents, exercising their authority as parents, have said it. So, that's the way it is.
In the life of the church, there have been seemingly endless debates and arguments over the Lord's Supper and what it is. Some say it's just a symbol. Some say it's just about thinking about Jesus. Some people say the bread and wine are just there to remind us about Jesus. Some say that Jesus is there in the Supper, but only in some mystical way, since He's really up in heaven.
What a joy it is that the Catechism teaches us simply: The Lord's Supper IS the body and blood of Jesus and it gives us the forgiveness of sins. Why? Because Jesus said so! There is no more powerful argument or bit of wisdom or logic or anything else than the simple words of Jesus, the Son of God who can make, do, give, and accomplish what He says. He is the Lord and His Word does what it says.
So, if Jesus says that this bread and wine are His body and blood; if Jesus says that eating and drinking His body and blood give the forgiveness of sins; if Jesus says these things are so, then they are! No doubts! No uncertainty! No wavering! No wondering! Every argument and silly discussion is knocked down and done away with for this one simple reason: Jesus' words are Jesus' words. If they were our words or someone else's, maybe we could question them. But, these are the words of the Son of God.
When you go to receive the Sacrament of the Altar, rejoice in what you receive, according to Jesus' words. Rejoice and don't doubt, because His words tell you: Forgiveness of sins is the gift given there. In the Name of Jesus. Amen.
His Word proclaims and we believe That in this Supper we receive His very body as He said, His very blood for sinners shed. (LSB 634:4)
