The pontifical vestments, also referred to as episcopal vestments or pontificals, are the liturgical vestments worn by bishops in the Roman Catholic, Eastern Orthodox, Eastern Catholic, Anglican, and some Lutheran churches, in addition to the usual priestly vestments for the celebration of the Mass and the other sacraments.
