Yes, I read that in Newman. I still maintain that no form of paganism had any more than practices, sometimes elaborate, and inchoate notions, traditional stories and myths in an effort to understand and express reality, without direct revelation. I know Newman uses the word “doctrine”, but there simply wasn’t anything approaching the doctrinal, properly speaking, before Christianity. Where is Plato’s Creed? Is Gilgamesh a doctrinal statement? Is Antigone or OEdipus Rex? Paganism is just an entirely different kind of thing.
paganism is from Cain who made up the first man made religion despite God's instructions.
The Catholic church embraces every pagan religion that it comes across and thus, great confusion (Babel) ensues and a mystery religion. Hysop's Two Babylons will explain it for you
True there has been much research and discovery in the last hundred years since Newman but his basic contention, that the Catholic Church can pronounce the sow’s ear of pagan practices acceptable as the silk purse of Christian worship still is the position of the Catholic Church.
