Newman was hardly ridiculing Christianity but rather pointing out the origins of what the Catholic Church was practicing under the rubric of Christianity.
The pagan practices may have been brought into the Catholic Church but the Christianity of the Scriptures was a God given revelation
And at the same time saying it didn’t matter as bringing such pagan teaching and practice into the Catholic Church some how “sanctified” it.
In this Newman was quite in line with The Catholic Encyclopedia quote I posted.
What are you talking about? I said the freethinker movement of the 19th century ridiculed and dimissed Christianity as merely another superstitious pagan corn god myth -- it has the dying-and-rising again god, the passage about "unless the seed fall into the ground and die," and the identification of Christ's body with bread -- open and shut case for the freethinkers. They also maintained that the world as we know it had always existed and always would, without any superfluous Creator.
Newman had nothing to do with them. He was part of the Oxford Movement. Maybe you confused them, though it's hard to see how.

Nobody claimed otherwise -- well, except for the freethinker movement!

What pagan "teaching"? AFAIK, there never was anything in any form of paganism that amounted to "teaching" in any meaningful sense of the word. They had practices and customs and the inborn impulse to worship they knew not what, made up some stories to fill the gap.
And, yes, Newman is in line with the Catholic Encyclopedia. So don't celebrate Christmas (the New England Puritans forbade any celebration of it) or have a Christmas tree or wear a wedding ring or sing at church services (without a church building, because that's pagan in origin) if you feel so strongly about it. It's still a free country, sort of.
