OldHippie,
well, there was a Man who was more than just a man and whose name was Jesus, and who was backed by some might forces, God and The Holy Spirit - and I guess that combination could produce slightly more growth than could early Mormonism or sociologic calculations assumptions .........
Actually, this factor could be considered in ANY debate that involves god as it's one that cannot be disproved.
If god could make christians flourish at that time....why didn't he prevent the persecution?
