“Tacitus is no better then the gospels, he was writing 200 years after the fact and only repeating rumors that he heard, that there was some cult following a guy named Christus.”
Wikipedia: The part of Tacitus’ annals that mentions Jesus was written in 116 AD. So we go from 200 years after the fact to less than 100. And for what it’s worth, “Overall the vast majority of scholars conclude that the passage is authentic and not a later interpolation.”
Regarding Josephus from Wiki: “Today almost no scholar holds that position: however, many writers claim that Josephus did write something about Jesus which has been corrupted in the surviving Greek text.”
Read the entry “Josephus on Jesus” for yourself - it’s pretty enlightening. The reality is that what Josephus said about Jesus is under dispute, and calling ‘beyond a shadow of a doubt a forgery’ evidences some… well. Grasping at straws. Josephus’ writings on Jesus are inconclusive - and there are two possible references to Christ in his writing according to the wikipedia, rather than just one.
As for the gospels: “Most critical scholars agree on the dating of the majority of the New Testament, except for the epistles and books that they consider to be pseudepigraphical (i.e., those thought not to be written by their traditional authors). For the Gospels they tend to date Mark no earlier than 65 and no later than 75. Matthew is dated between 70 and 85. Luke is usually placed within 80 to 95. The earliest of the books of the New Testament was First Thessalonians, an epistle of Paul, written probably in 51, or possibly Galatians in 49 according to one of two theories of its writing. Of the pseudepigraphical epistles, Christian scholars tend to place them somewhere between 70 and 150, with Second Peter usually being the latest.”
So ‘no better than the gospels’ would place our earliest known NT manuscripts within a few decades of Christ’s death (and resurrection ).
In other words, the history of Jesus has this to say: The quoted claims are extraordinarily off-base. Either by intention or accident.
