A belt, especially if a cord or rope, is called a girdle if it is worn as part of Christian liturgical vestments, or in certain historical, literary or sports contexts. Girdles are used to close a cassock in Christian denominations, including the Anglican Communion, Catholic Church, Methodist Church and Lutheran Church. The girdle, in the 8th or 9th century, was said to resemble an ancient Levitical Jewish vestment, and in that era, was not visible. In 800 AD, the girdle began to be worn by Christian deacons in the Eastern Church.
