In some church traditions all of the altar coverings and decorations are removed after the Eucharist is celebrated on Maundy Thursday. Psalm 22 is sometimes either read or sung while the altar paraments are being removed. Since the altar in these traditions symbolize the Christ, the "stripping of the altar" symbolizes the abandonment of Jesus by his disciples and the stripping of Jesus by the soldiers prior to his crucifixion. This, like the darkness often incorporated into a Good Friday service, represents the humiliation of Jesus and the consequences of sin as a preparation for the celebration of new life and hope that is to come on Resurrection Day. Some churches only leave the altar bare until the Good Friday Service, when the normal coverings are replaced with black.
