“In the entire first Christian Century, Jesus is not mentioned by a single Greek or Roman historian, religion scholar, politician, philosopher or poet.”
I guess the emperor was a fool making it the official religion of the Roman Empire.
You're off by a couple of centuries. Emperor Constantine did reign until 306 AD 337 AD. These guys are talking about 1 AD to 100 AD. . . Except they'd say 1 CE to 100 CE most likely, pretending the initiating event that established the zero year did not occur, being Atheists.
