Indicating the non-Christian origin of many of apostate Christendom’s doctrines, ceremonies, and practices, 19th-century Roman Catholic cardinal John Henry Newman wrote in his Essay on the Development of Christian Doctrine: “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 [the song “Lord, Have Mercy”], are all of pagan origin, and sanctified by their adoption into the Church.”
Rather than sanctify such idolatry, “Jehovah the Almighty” admonishes Christians: “Get out from among them, and separate yourselves, . . . and quit touching the unclean thing.”—2 Corinthians 6:14-18.
