An altar cloth is used in the Christian liturgy to cover the altar. It serves as a sign of reverence as well as a decoration and a protection of the altar and the sacred vessels. In the orthodox churches is covered by the antimension, which also contains the relics of saints. Since the 2nd century the altar cloth has been seen as a symbol for the shroud of Jesus Christ; therefore it should be made of white linen. Another interpretation used two cloths and compared them with the body and soul of Christ. Christian altar cloths Western Churches Special cloths (not necessarily made of linen) cover the altar in many Christian churches during services and celebrations, and are often left on the altar when it is not in use. In the early 20th century the Catholic Church considered only linen or hemp to be acceptable as material for altar cloths, although in earlier centuries silk or cloth of gold or silver were used. The Anglican Communion had similar rules in that period. At that time, the Roman Rite required the use of three altar cloths, to which a cere cloth, not classified as an altar cloth, was generally added. This was a piece of heavy linen treated with wax (cera, from which "cere" is derived, is the Latin word for "wax") to protect the altar linens from the dampness of a stone altar, and also to prevent the altar from being stained by any wine that may be spilled. It was exactly the same size as the mensa (the flat rectangular upper surface of the altar). Above this were placed two linen cloths. Like the cere cloth, they were made of heavy linen exactly the same size as the mensa of the altar. They acted as a cushion and, with the cere cloth, prevented the altar from being dented by heavy vases or communion vessels placed on top. Instead of two cloths, a single long cloth folded so that each half covered the whole mensa was acceptable. The topmost cloth was the fair linen, a long white linen cloth laid over the two linen cloths. It had the same depth as the mensa of the altar, but was longer, generally hanging over the edges to within a few inches of the floor or, according to some authorities, it should hang over the ends of the mensa.
