316 The Faith of Our Fathers [333] undertone. And this was the system of worship God ordained in the ancient dispensation, as we learn from the Old Testament and from the first chapter of St. Luke. The Priest offered sacrifice and prayed for the people in the sanctuary, while they prayed at a distance in the court. In all the schismatic churches of the East the Priest in the public service prays not in the vulgar, but in a dead language. Such, also, is the practice in the Jewish synagogues at this day. The Rabbi reads the prayers in Hebrew, a language with which many of the congregation are not familiar. But is it true that the people do not understand what the Priest says at Mass? Not at all. For, by the aid of an English Missal, or any other Manual, they are able to follow the officiating clergyman from the beginning to the end of the service. You also observe lighted tapers on the altar, and you desire to know for what purpose they are used. In the Old Law the Almighty Himself ordained that lighted chandeliers should adorn the tabernacle.428 Assuredly, that cannot be improper in the New Dispensation which God sanctioned in the Old. The lights upon our altars have both a historical and a symbolical meaning. In the primitive days of the Church Christianity was not tolerated by the Pagan world. The Christians were, consequently, obliged to assemble for public worship in the Catacombs of Rome and other secret places. These Catacombs, or subterranean rooms, still exist, and are objects of deep interest to the pious stranger visiting the Eternal City. As these hidden apartments did not admit the light of the sun, the faithful were [334] obliged to have lights even in open day. In commemoration of the event the Church has retained the use of lights on her altars. Lighted candles have also a symbolical meaning. They represent our Savior, who is "the light of the world," "who enlighteneth every man that cometh into the world," without 428 Exod. xxv. 31, and seq.
