The credence table is usually placed near the wall on the epistle (south) side of the sanctuary, and may be covered with a fine linen cloth. It is sometimes tended by an altar server, and contains on it the implements that are used in the Eucharistic celebration, which may include the bread and wine prior to their consecration, a bowl, ewer and towel for the lavabo and the ablutions after Holy Communion, etc. The wafers for the communion of the faithful may be stored in a host box (sometimes erroneously referred to as a pyx). The wine and water for the chalice will be in cruets. The chalice, and paten, covered with their cloths and veil (see chalice cloths for details) may be placed on the credence from the beginning of the service until the Offertory, at which time they are moved to the altar.
In the traditional Roman Catholic Mass, the chalice, and paten, covered with their cloths and veil (see chalice cloths for details) are placed on the credence from the beginning of the service until the Offertory.
During the Offertory, the subdeacon, deacon or priest places the sacred vessels on the altar. The wine and water are taken in their cruets to the altar to be poured into the chalice. After the altar has been incensed (if it is a High Mass), two servers wash the priest's hands. The priest will hold his hands over the lavabo bowl and the first server (if there are two) will pour water over the priest's hands; the second server then hands the priest the lavabo towel for him to dry his fingers. During the washing, the priest says the words of . When a bishop is serving, a larger and more ornate basin and ewer are used to wash his hands.
After Communion, when the priest or deacon consume the remaining elements in the chalice
Traditionally, at Low Mass, the credence was not used, but a niche in the wall was used instead.
In the Eucharist of the Anglican Communion the ceremonial regarding the use of the credence table is not so elaborate. Depending upon local custom, the chalice and paten may already be on the altar from the beginning of the service. Normally the server will bring the wine, water and wafers to the priest at the offertory, and then wash his hands.
The term credence table is not normally found in use among the Eastern Orthodox. All of the items for the celebration of the Divine Liturgy are normally placed on the Table of Oblation. There is, however, an ancillary table on which other items, such as the lists containing the names of the faithful living and departed whom the priest will commemorate, will be placed. Other items, such as incense and a bowl and towel for the washing of hands may be there also.
