In Short

In the Lord’s Supper we receive the forgiveness of sins.

“While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, ‘Take and eat; this is my body.’ Then he took a cup, and when he had given thanks, he gave it to them, saying, ‘Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins.'”
Matthew 26:26-28

“And he took bread, gave thanks and broke it, and gave it to them, saying, ‘This is my body given for you; do this in remembrance of me.’ In the same way, after the supper he took the cup, saying, ‘This cup is the new covenant in my blood, which is poured out for you.'”
Luke 22:19-20

“‘The days are coming,’ declares the LORD, ‘when I will make a new covenant with the people of Israel and with the people of Judah…I will forgive their wickedness and will remember their sins no more.'”
Jeremiah 31:31-34

Jesus’ true body and blood are present in the bread and the wine 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. So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. Everyone ought to examine themselves before they eat of the bread and drink from the cup. For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.”
1 Corinthians 11:23-29

We share a special fellowship with those who partake of the Lord’s Supper with us.

“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 share the one loaf.”
1 Corinthians 10:16-17

“They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer.”
Acts 2:42
