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, are all of pagan origin, and sanctified by their adoption into the Church.[Cardinal Newman - Development of Christian Doctrine, pg 373]
