In the context of the Tridentine Mass of the Catholic Church, a Pontifical High Mass, also called Solemn Pontifical Mass, is a Solemn or High Mass celebrated by a bishop using certain prescribed ceremonies. The term is also used among Anglo-Catholic Anglicans. Although in modern English the word "pontifical" is almost exclusively associated with the Pope, any bishop may be properly called a pontiff. Thus, the celebrant of a Pontifical High Mass may be the pope, any bishop or any other prelate who is allowed to wear pontificals.
