“SACRED VESSELS AND ACCESSORIES
• For the celebration of Holy Mass the priest needs two Sacred Vessels – the PATEN and the CHALICE. The Paten is a small plate of gold or gilded silver, on which is placed the HOST. The Chalice, also made of precious metal, contains the WINE. The Host is made of pure wheat flour and is baked between two irons. The Wine is unadulterated juice of the grape naturally fermented. In preparation for Mass the priest places on the cup of the Chalice a small linen cloth. It is used to wipe the Chalice before the Wine is put into it, and wipe it again after Communion. This cloth is called the PURIFICATOR.
• Over the Purificator the priest places the Paten, on the top of which he puts the PALL – a small square of stiff linen which prevents dust or other impurities from falling into the Chalice during Mass.
• Completely covering the Chalice is the CHALICE VEIL. It is a square of silk, fashioned of the same material and having the same colour as the vestments the priest wears. On the Veil is placed the BURSE in which is carried the CORPORAL. The Corporal is a Linen Cloth, approximately a foot square, that serves as a small tablecloth on which the Sacred Vessels rest during the Mass.
• The CIBORIUM is a vessel made of precious metal. It is usually larger than the Chalice and is covered with a lid. In it are kept the Sacred Hosts reserved for Holy Communion.
• For Exposition of the Blessed Sacrament and Benediction of the Blessed Sacrament the MONSTRANCE is used. It is made of precious metal and is designed to hold the Blessed Sacrament in public view for adoration and to be raised in blessing the Faithful. It contains the LUNETTE, a crescent-shaped device of gold or silver used for holding the Host in an upright position.”
