Altar (Catholicism) - Position

Position

In the ancient basilicas the priest, as he stood at the altar, faced the people. The basilicas of the Roman Empire were, as a rule, law courts or meeting places. They were generally spacious, and the interior area was separated by two, or, it might be, four rows of pillars, forming a central nave and side aisles. The end opposite the entrance had a semi-circular shape, called the apse, and in this portion, which was raised above the level of the floor, sat the judge and his assessors, while right before him stood an altar upon which sacrifice was offered before beginning any important public business.

When these public buildings were adapted for Christian assemblies, slight modifications were made. The apse was reserved for the bishop and his clergy; the faithful occupied the centre and side aisles, while between the clergy and people stood the altar. Later on the altar was placed, in churches, in the apse against, or at least near, the wall, so that the priest when celebrating faced the east, and behind him the people were placed. In primitive times there was but one altar in each church. Ignatius the Martyr, Cyprian, Irenaeus, and Jerome, speak of only one altar (Benedict XIV, De Sacr. Missae, no. 1, xvii). Some think that more than one altar existed in the Cathedral of Milan in the time of St. Ambrose, because he sometimes uses the word altaria, although others are of opinion that altaria in this place means an altar.

Towards the end of the sixth century we find evidence of a plurality of altars, for Gregory the Great sent relics for four altars to Palladius, Bishop of Saintes, France, who had placed in a church thirteen altars, four of which remained unconsecrated for want of relics. Although there was only one altar in each church, minor altars were erected in side chapels, which were distinct buildings (as is the custom in the Greek, and some Oriental Churches even at the present day) in which Mass was celebrated only once on the same day in each church (Benedict XIV, Ibidem). The fact that in the early ages of Christianity only the bishop celebrated Mass, assisted by his clergy, who received Holy Communion from the bishop's hands, is the reason that only one altar was erected in each church, but after the introduction of private Masses the necessity of several altars in each church arose.

In ceremonials there is mention of the right and left side of the altar. Before 1488, the epistle side was called the right side of the altar, and the gospel side the left. In that year, Augustine Patrizi, Bishop of Pienza, published a ceremonial in which the epistle side is called the left of the altar, and the gospel side the right, the denomination being taken from the facing of the crucifix, the principal ornament of the altar, not of the priest or the laity. This change of expression was accepted by Pope Pius V and introduced into the rubrics.
