Do I need to be a contemporary to refer to Julius Caesar?
James was Jesus' brother. Jesus is in the book of Thomas, who was a disciple of His. You just referred to Washington, and I don't think you were a contemporary of Georges.
I was showing this to be incorrect:
I'm glad you brought that up.
Julius Caesar, like Jesus, was also worshipped as a God.
But we have a lot more attestations to his existence. We know what day he was born, (July 12, 100 BCE) and what day he died (March 15th, 44 BCE). We have statues of him that were created in his own lifetime. We have coins with his picture on them. We have contemporary writers who wrote about him. We have a century of rule by his family (The Julio-Claudian Dynasty, which ended with Nero.)
Now, for the Gospel of Thomas, which is considered apocryphal. No one believes it was written by the Thomas who was a disciple of Jesus. Just like we know the Apostle Matthew didn't write the Gospel of Matthew. (It would be silly, as Matthew heavily cribbed from Mark) We know, in fact, that most of these Gospels were written at best 50 years after the "death" Of Jesus and perhaps as much as 100 years later or more.
We also know that these Gospels (Not only the four canonical ones, but the dozens of others) contradict themselves on many key points, get things wrong, can't agree on a coherent timeline for Jesus' life.
I'll give you just one example
Matthew says Jesus was born in Bethlehem, but his family had to flee to Egypt to avoid Herod's decree to kill all the infants. (An incident that no other Gospel writer or historian mentions.) After Herod's death, Joseph and Mary settle in Nazareth in Galilee.
Luke says that Joseph and Mary lived in Galilee, but because Caesar Augustus declared a census for the whole world, all people were required to return to the towns of their ancestors. It mentions this happened when Cyraneus (Quirinius) was governor in Syria.
Now for the mind-bending part. Herod died in 4 BCE. Cyraneus didn't become governor of Syria until 6 AD. (Rome didn't officially annex Iudea until 6 AD, after Herod's son proved to be incompetent to rule.)
So now you have a TEN-YEAR gap between when Jesus was born, according to the bible.
They both can't be right.
