Bible is essentially the sole source, a novel of historical fiction. Just enough reality tossed in to make it all real. You’d think news that a dude running around magically healing people, or magically creating food and wine, would have spread like wildfire and the authorities would have snatched him up immediately and made him serve the wealthy and powerful on demand. Greed hasn’t changed in thousands of years, there would have been official Roman records of magical deeds. But no, it wasn’t the magic that bothered the authorities, it was bucking the system.
