P. Andrew Sandlin's article on weekly Communion provides a needed contrast:
In some churches, communion is a time of fear and lamentation and even trembling over sins committed. But the Lord’s Supper is all about God’s overcoming our sins in the atoning death and victorious resurrection of Jesus. So, there is joyous music, laughter, tears and hope — because of what God has done, is doing, and will do in His Son Jesus. The Lord’s Supper is (among other things) a celebration of our victory in Jesus.
