History unveils what and where the origin of it comes from...
Cardinal Newman lists many examples of things of "pagan origin" which the papacy brought into the church "in order to recommend the new religion to the heathen: He stated, "in order to recommend the new religion to the heathen:" "The use of temples, and these dedicated to particular saints, and ornamented on occasions with branches of trees; incense, lamps, and candles; holy water; asylums [hermitages, monasteries and convents]; [pagan] holy-days, processions, sacerdotal vestments, the tonsure, the ring in marriage, turning to the East, images, . . . and the Kyrie Eleison."--Cardinal J. H. Newman, An Essay on the Development of Christian Doctrine, 1920 edition, p.373 [Roman Catholic].
Cardinal Newman admits in his book that; the "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, ...the ecclesiastical chant, and the Kyrie Eleison, are all of pagan origin, and sanctified by their adoption into the Church. {374}" -An Essay on the The Development of the Christian Doctrine John Henry "Cardinal Newman" p.359 (Also see According to Dr. E. D. Clarke, Travels, vol. i. p. 352.)
"The [Catholic] Church took the pagan philosophy and made it the buckler of faith against the heathen. She took the pagan Roman Pantheon, temple of all the gods, and made it sacred to all the martyrs; so it stands to this day. She took the pagan Sunday and made it the Christian Sunday. She took the pagan Easter and made it the feast we celebrate during this season . . . The Sun was a foremost god with heathendom . . . The sun has worshipers at this hour in Persia and other lands . . . Hence the Church would seem to say, 'Keep that old pagan name [Sunday]. It shall remain consecrated, sanctified.' And thus the pagan Sunday, dedicated to Balder, became the Christian Sunday, sacred to Jesus"--William L. Gildea, "Paschale Gaudium," in The Catholic World, 58, March, 1894, p. 809 [A Roman Catholic weekly].
"The mighty Catholic Church was little more then the Roman Empire baptized."-- A. C, Flick, The Rise of the Mediaeval Church, 1909 edition, p. 148.
From ancient Babylon came the cult of the virgin mother-goddess, who was worshiped as the highest of gods--see S. H. Langdon, Semitic Mythology, 1931 edition.
This worship was taken over as Mary-worship by Rome. Heathen sun-worship on Sunday was likewise adopted by the Roman apostasy.
"In order to attach to Christianity great attraction in the eyes of the nobility, the priests adopted the outer garments and adornments which were used in pagan cults." -Life of Constantine, Eusabius, cited in Altai-Nimalaya, p. 94
"The Church did everything it could to stamp out such 'pagan' rites, but had to capitualet and allow the rites to continue with only the name of the local diety changed to some Christian saint's name." -Religious Tradition and Myth. Dr. Edwin Goodenough, Professor of Religion, Harvard University. p. 56, 57
"From the foregoing, which treats merely of the more important solar festivals, it is clear that these products of paganism are as much in force at present ... as they ever were, and that Christianity countenances, and in many cases has actually adopted and practiced, pagan rites whose heathen significance is merely lost sight of because attention is not called tot the source whence these rites have sprung. So heavy was this infiltration that Sir Samuel Dill exclaims: "Christianity is only a sect of the Mithraists." -Roman Society from Nero to Marcus Aurelius, p. VII
"In short, sun worship, symbolically speaking, lies at the very heart of the great festivals which the Christian Church celebrates today, and these relics of heathen religion have, through the medium of their sacred rites, curiously enough blended with practices and beliefs utterly antagonistic to the spirit which prompted them." -Sun Lore of All Ages, Olcott, p. 248
"When the zealots of the primitave Christian Church sought to Christianize paganism, the pagan initiates retorted with a powerful effort to paganize Christianity. The Christians failed but the pagans succeeded. With the decline of paganism the initiated pagan hierophants transferred their base of operations to the new vehicle of primitive Christianity, adopting the symbols of the new cult to conceal those eternal verities which are ever the priceless possession of the wise." -The secret teachings of all ages, Manley P. Hall p. CLXXXV
The Christians failed because Christ would have no agreement with such error. He would never sanction mixing truth with error. Deuteronomy 12:29-32 confirms that perfectly!
"...The world, cloaked with a form of righteousness, walked into the church. Now the work of corruption rapidly progressed. Paganism, while appearing to be vanquished, became the conqueror. Her spirit controlled the church. Her doctrines, ceremonies, and superstitions were incorporated into the faith and worship of the professed followers of Christ." Ellen G.White, -The Great Controversy, p. 50
"The belief in miracle-working objects, talismans, amulets, and formulas was dear to Christianity, and they were received from pagan antiquity . . . The vestments of the clergy and the papal title of 'pontifex maximus' were legacies from pagan Rome. The [Catholic] Church found that rural converts still revered certain springs, wells, trees, and stones; she thought it wiser to bless these to Christian use then to break too sharply the customs of sentiment . . . Pagan festivals dear to the people, reappeared as Christian feasts, and pagan rites were transformed into Christian liturgy . . . The Christian calendar of saints replaced the Roman 'fasti' [gods]; ancient divinities dear to the people were allowed to revive under the names of 'Christian saints' . . . Gradually the tenderest features of Astarte, Cybele, Artemis, Diana, and Isis were gathered together in the worship of Mary"--Wil Durant, The Age of Faith, 1950, pp. 745-746.
Langdon tells us that Mary worship came from ancient Babylon where the virgin mother-goddess was worshiped under the name "Ishtar." Elsewhere in the Near East, the mother-goddess was called "Astarte, Ashtoreth, Persephone, Artemis, [Diana] of Ephesus, Venus, and Isis." This goddess, considered to be greater than any god, was called by these heathen the "virgin mother, merciful mother, Queen of Heaven, and my lady" [which is what "Madonna" means in Italian]. Langdon says she was often sculptured in mother-and-infant images, or as a "mater dolorom" [sorrowful mother] interceding for men with a wrathful god. And thus ancient paganism was brought into the churches and lives of Christians.--see S.H. Langdon, Semitic Mythology, 1931 edition, pp. 12-34, 108-111, 341-344.
Laing mentions several other corruptions by which the mother-goddess was worshiped by heathens, that Rome adopted into Christianity: holy water, votive offerings, elevation of sacred objects [lifting of the host], the priest's bells, the decking of images, processions, festivals, prayers for the dead, the worship of relics and the statues of saints.--see Gordon J. Laing, Survivals of Roman Religion, 1931 edition, pp. 92-95, 123-131,238-241.
Two dominant elements brought into Christianity from paganism by Rome were Sun worship symbols and the religious practices of ancient Babylon] "The solar theology of the Chaldaeans [Babylonians], had decisive effect . . . [upon the] final form reached by the religion of the pagan Semites, and following them, by that of the Romans when [the Roman emperor] Aurelian, the conqueror of Palmyra, had raised 'Sol Invictus' [the invincible sun-god] to the rank of supreme divinity in the Empire"--The Cambridge Ancient History, vol. 11, pp. 643, 646-647. From Palmyra he transferred to the new sanctuary the images of Helios [the sun-god] and Bel, the malaise patron god of Babylon--see Cumont, The Oriental Religions In Roman Paganism, 1911 edition, pp. 114-115, 124.
