Altar cloth

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 Orthodox churches it 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.

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 18 inches (46 cm) over the ends of the mensa. On an altar without antependium and consisting of the mensa resting on columns or made after the fashion of a tomb the topmost linen did not have to overhang the edges at the sides. It could be trimmed with lace on the ends and could be ornamented with figures of chalices, hosts and the like. Five small crosses might be embroidered on the fair linen – one to fall at each corner of the mensa, and one in the middle of the front edge. These symbolised the five wounds of Jesus. The fair linen should be left on the altar at all times. When removed for replacement, it should be rolled, not folded. It symbolized the shroud in which Jesus was wrapped for burial.

The present rules of the Roman Rite are much less detailed, stating only:

Out of reverence for the celebration of the memorial of the Lord and for the banquet in which the Body and Blood of the Lord are offered, there should be, on an altar where this is celebrated, at least one cloth, white in colour, whose shape, size, and decoration are in keeping with the altar's structure.
