Not pagan, mostly Gentile, and Christian.
Yeah, uh hu, sure.
“We need not shrink from admitting that candles, like incense and lustral water, were commonly employed in pagan worship and the rites paid to the dead. But the Church from a very early period took them into her service, just as she adopted many other things indifferent in themselves, which seemed proper to enhance the splendor of religious ceremonial. We must not forget that most of these adjuncts to worship, like music, lights, perfumes, ablutions, floral decorations, canopies, fans, screens, bells, vestments etc. were not identified with any idolatrous cult in particular; but they were common to almost all cults” (Catholic Encyclopedia, III, 246.)
