Colors of vestments (and hangings, if kept) vary: no colour, red, or black are used in different traditions. The Catholic Church uses red vestments, symbolic of the blood of Jesus Christ, but in the pre-1970 form of the Roman Missal the priest wears black, changing to violet for the communion part of the service. In Anglican services, black vestments are sometimes used. In the United Methodist Church, black is the liturgical colour used on Good Friday. In the Lutheran churches, there is no liturgical color on Good Friday. Altars remain stripped and clergy wear no vestments on this day.
