In the Roman Catholic, Lutheran, and Anglo-Catholic rites, a cross or crucifix (not necessarily the one that stands on or near the altar on other days of the year) is ceremonially unveiled. (In pre-1955 services, other crucifixes were to be unveiled, without ceremony, after the Good Friday service.) In the Catholic ritual, clergy traditionally begin the service prostrate in front of the altar. Mass is not celebrated on Good Friday and the communion distributed at the Celebration of the Lord's Passion is consecrated on Holy Thursday, hence the pre-1955 name "Mass of the Presanctified". In Anglican churches, there is no prayer of consecration on Good Friday, and the Reserved Sacrament is distributed at services on that day.
