Quote:Why did christianity emerge so rapidly, with such power?
It apparently did not.
So not only does this asshole have to demonstrate that the the laws of nature were suspended ( the definition of a 'miracle') so that someone could "come back from the fucking dead" but he must also show evidence ( and not bible-based bullshit) that this particular cult of idiots did emerge rapidly.
Xtianity, when it unfortunately for the rest of us, backed the right horse during the Constantine-Maxentius civil war, was handed the keys to power. Every indication we have from historical sources is that it was still a fairly minor cult at that time as these things were reckoned in the Roman empire. Estimates are 5 to 10% of the population were xtian by the time of Constantine and most of those were in the East. If you contrast that with the rapid spread of islam in the first 2 centuries after it was concocted you'll see that xtianity was quite the laggard.
You seem overly impressed with the bullshit these people put out but taking their claims critically instead of literally would be a good way to start.
