There is more to the Lord’s table than confession of sin. While we ought not harbor sin, if we are keeping short accounts, confessing and repenting and believing, then there is every reason for our remembrance of Him to be a serious celebration. We take His sacrifice seriously and we take our joyous participation in His sacrifice seriously.
Consider the context of Paul’s warning to the Corinthians regarding communion in his first letter. Why did he correct them in this way (1 Corinthians 11:17-34)? Because they were coming to the table selfishly, focused on themselves and not on the entire body. They were also treating the table more like a party.
We are not in, or anywhere near, the “communion as a party” ditch. That said, we may not be in the middle of the road either. We are still focused on the wrong thing: ourselves, just as the Corinthians were. We just feel better about it because at least we’re taking our sin seriously.
When the angels watch us take the bread and the cup, what impresses them? Does anything about it make them nervous? Are they confronted with the manifold wisdom of God as they see us sitting in our isolated conviction over sin? Or are they taken back with the manifold wisdom of God as they see us–sinners against God and against each other–singing together over the forgiveness and fellowship we have with God and with each other through the gospel of grace?
The Church–Jew and Gentile, slave and freeman, male and female, hands and feet, unlovely and unlikeable–together make a point to the universe. Christ Himself “is our peace, who has made us both one” (Ephesians 2:14). He has reconciled us “to God in one body through the cross” (2:16) and in Him, “the whole structure, being joined together, grows into a holy temple in the Lord. In him [we] also are being built together into a dwelling place for God by the Spirit” (2:21-22).
The Lord’s table is a purifying and unifying ordinance. We should get out of the ditch, whichever one we’re in, and participate accordingly.
