Interesting Point of History

According to Dr. Vic Pentz, the pastor at Peachtree Presbyterian Church in Atlanta, Georgia:

The historian, Ramsey McMollen[?], did a study on the growth of Christianity, beginning with the end of the first century, 100 AD. And Ramsey McMollen studied its mushrooming explosion across the Roman empire. The Christian faith added half a million people every generatin for two centuries — for every 20 years, there was another half a million people, until 300 AD. At that point, at 300 AD, Christians were a majority (or close to it) in many of the cities of the Roman Empire. And it was then that Constantine had his famous vision, and he went on to make an edict in which Chrisitanity became the official religion of the Roman empire.

I always thought that the incredible growth of early Christianity was after Constantine’s conversion, not before it.
