Paul's Writings Underpin Western Thought

[Angrboda]

Christianity is far from a minority in the U.S.  Your contention is just silly.  Whether Constantine saw something in any supposed tide or that a minority that is not part and parcel of a larger majority might have influence, you've walked back from assertive claim into the land of speculative and far fetched nonsense.

Then why do so many theists point to Constantine as an important figure to the rise of Christianity?

You mean aside from his conversion and him legalizing Christianity at the time? Jesus Christ Brian.
