The chasuble is the outermost liturgical vestment worn by clergy for the celebration of the Eucharist in Western-traition Christian Churches that use full vestments, primarily in the Roman Catholic Church, in "high church" and "broad church" Anglican congregations, and in some parts of the United Methodist and Lutheran Churches. It is also used as the primary Eucharistic vestment in many Lutheran parishes (see Apology of the Augsburg Confession, Article XXIV). In the Eastern Churches of Byzantine Rite, the equivalent vestment is the phelonion.
