The example set by St. Gregory in an age of persecution was impetuously followed when a time of peace succeeded. In the course of the fourth century two movements or developments spread over the face of Christendom, with a rapidity characteristic of the Church; the one ascetic, the other ritual or ceremonial. We are told in various ways by Eusebius [Note 16], that Constantine, in order to recommend the new religion to the heathen, transferred into it the outward ornaments to which they had been accustomed in their own. It is not necessary to go into a subject which the diligence of Protestant writers has made familiar to most of us. The use of temples, and these dedicated to particular saints, and ornamented on occasions with branches of trees; incense, lamps, and candles; votive offerings on recovery from illness; holy water; asylums; holydays and seasons, use of calendars, processions, blessings on the fields; sacerdotal vestments, the tonsure, the ring in marriage, turning to the East, images at a later date, perhaps the ecclesiastical chant, and the Kyrie Eleison [Note 17], are all of pagan origin, and sanctified by their adoption into the Church. {374}
