Paul's Writings Underpin Western Thought

[Brian37]

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.

I think you miss the point that countless apologists point to that point in history as when the pagans fell as rulers and when the religion took off. There was nothing to the rise of Christianity other than marketing for it to get as big as it did. Constantine is widely pointed at as the point of when the world changed, according to Christians.

Constantine saw something in it, otherwise why adapt it? Be it genuine or tactical could care less. It could have been both. But back then if you were a king, you still play politics and you still use religion to play politics.
