Here’s a neat little paragraph succinctly summarizing one of the many problems with the passage in the works of the Jewish historian Josephus used to “prove” the historicity of Jesus Christ, called the “Testimonium Flavianum”:
“Its brevity disproves its authenticity. Josephus’ work is voluminous and exhaustive. It comprises 20 books. Whole pages are devoted to petty robbers and obscure seditious leaders. Nearly forty chapters are devoted to the life of a single king. Yet this remarkable being, the greatest product of his race, a being of whom the prophets foretold ten thousand wonderful things, a being greater than any earthly king, is dismissed in a dozen lines.”
John Remsburg, The Christ (29)
There is much more, of course, although one would think this argument alone would suffice to prove this passage is fake in toto. Yet, because it often contended that the TF is the “best evidence” for Christ’s historicity, it is fought for tooth and nail. Hence, the existence of the world’s most famous man essentially rests on a brief and palpably bogus forgery.
