Three thousand years ago everyone each had their own ideas about God, until they all converted to one man when he came back down the mountain with the Law. A thousand years later there were diverse and squabbling sects and everyone each had his own ideas about God, until they all converted to one man when he rose from the dead. Now two thousand years later and they're at it again..
The Torah, Bible and Quran are 3 drafts of the same BS, with Islam having the distinction of being the most sadistic, and malevolent of all, by far.
"Until they ALL converted to the man who rose from the dead"? With the exception of a few individuals, the two squabbling sects did not, and have multiplied to even more squabbling sects of today.
