The opening as it read in 2005

A sanctuary lamp is a red light which is hung or displayed in the Churches of those Christian faiths who believe in transubstantiation . It is placed, often in a gold or brass candelabrum in or near the vicinity of the altar , indicating that anyone approaching the altar should genuflect (i.e., bow by bending the knee and inclining the head), to show respect for Christ , who according to the theology behind substantiation, is present in the communion wafers in the Tabernacle . The belief that Christ is physically and not just symbolically present in the tabernacle is called the Real Presence . A sanctuary lamp in a Roman Catholic Church1
