WFS: I think your incorrect in saying there are only 2 reliable sources. What makes them very reliable is the time when they were written, the reliability of the people who wrote them, and if that style written is consistent all the way through with that person (don't want fogeries). A dozen of them were written in the first century . Some of the best known writers are Plinoy, Jocepius, Tacitus and Suetonius. I'm am unsure if there are multiple copies of them, but i would assume so, this is something I'll look into too (some of them were written as texts). I only know that the dating for them is very early and shouldnt be discredited due to lack of copies. If there were only one or two accounts this wouldnt be possible, but since there are a dozen reliable people writing about this man, in a way they corroborate the existence of Jesus Christ in history.
Quoted Quoted by Craig L. Bloomberg
(10) A dozen or so non-Christian writers or texts confirm a remarkable number of details in the Gospels about Jesus' life-that he was a Jew living in the first third of the first century, born out of wedlock, a self-styled teacher who became very popular, selected certain men as his inner core of disciples, disregarded Jewish dietary laws and ate with the despised, enraged certain Jewish leaders, even though believed to be the Messiah by others, was crucified by Pontius Pilate but believed to have been raised from the dead by some of his followers who began a fledgling religion that never died out. Some might argue that this does not seem like a lot of detail but in a world in which almost all historical and biographical writing focused on kings, emperors, military generals, people in institutional positions of religious power, famous philosophers whose "schools" had long outlived them, and, more generally, the well-to-do and influential, it is remarkable that Jesus gets mentioned at all by first-through-third century non-Christian writers. Before the legalization of Christianity in the fourth century, who would have expected this obscure, crucified rabbi to produce a following that would one day become the religion adopted by the greatest percentage of people on earth?
