On the south side of the Altar is a small table or shelf, called the credence, on which are placed the elements of bread and wine until such time in the service as they are offered for consecration on the Altar. Here also the alms-basin is placed before the Offertory, and the cruets containing the wine and the water for the ablutions at the close of the service. When the communicants are not too many, a part of the wine from the cruet is poured into the chalice at the proper time; but if a large number are to communicate, the flagon, a large vessel of silver, is used to hold the wine and is placed on the credence.

Nothing should be placed on the Altar itself but the Altar-desk, for holding the book of the Altar-service, and the Altar-vessels. These are usually the paten, or plate for holding the bread at the Celebration, and the chalice, the cup for the wine. There is sometimes a spoon with a perforated bowl to use in case any foreign substance is found in the chalice. If possible these vessels should be of precious metal. They are sometimes adorned with jewels.

A rubric directs that at the time of the Communion the Altar shall be covered with a "fair white linen cloth" ("fair," that is, not only clean, but beautiful). Another "fair linen cloth," commonly called the "linen chalice veil," is also directed to be used for covering the consecrated elements after the communion of the people. To these custom has added other convenient and seemly appointments of linen and silk.

The "chalice veil" is a square of silk, embroidered and often fringed, used to cover the vessels before the consecration.

The "pall" is a square of cardboard covered with linen, used to cover the chalice during the Celebration.

The "corporal" is a square of linen spread upon the Altar at the Celebration, upon which the vessels are placed.

The "purificators" are small napkins of linen for cleansing the vessels after the service.

The "burse" is a square, stiff pocket of silk over cardboard, in which the Altar-linen is carried to and from the Altar.

The color of the chalice veil and the burse follows that of the season. The linen pieces are always white. They are supposed to represent the cloths which were wound around our Lord's sacred body and wrapped about His head at His burial.
