Communion is also known as the Lord's Supper (Matt. 26:26-30, Mark 14:22-26, Luke 22:14-20, 1 Cor. 11:23-26). It is the breaking of bread (Acts 2:42, 46) and a time to give thanks (Luke 22:17, 19). It was originally instituted by Jesus (Matt. 26:26-29) on the night of the Passover meal which was an annual occurrence celebrating the "passing over" of the angel of death that claimed the firstborn of every house in Egypt (Exodus 12). The Lord's Supper, or communion, replaces the Passover meal with the "body and blood" (Mark 14:22-24) of Jesus. It is to be taken only by believers (1 Cor. 11:23-28).
