The teacher said many christian try to use evidence of a Jewish man called Josephus.
the teacher responce and research on this was this:
Another famous historian of the period was Flavius Josephus, who lived from around 37AD to 97 AD. (Look in the INDEX of The Christ Conspiracy and find the pages about Josephus’ works. See what she says). In his "Antiquities" he wrote two passages of interest, the first referring to James as "the brother of Jesus, who was called Christ." (20:9). The second reference is more explicit,
"At this time there was a wise man who was called Jesus. His conduct was good and (he) was known to be virtuous. And many people from among the Jews and the other nations became his disciples. Pilate condemned him to be crucified and to die. But those who had become his disciples did not abandon his discipleship. They reported that he had appeared to them three days after his crucifixion, and that he was alive; accordingly he was perhaps the Messiah, concerning whom the prophets have recounted wonders."
“ Now there was about this time Jesus, a wise man, if it be lawful to call him a man; for he was a doer of wonderful works, a teacher of such men as receive the truth with pleasure. He drew over to him both many of the Jews and many of the Gentiles. He was [the] Christ. And when Pilate, at the suggestion of the principal men amongst us, had condemned him to the cross, those that loved him at the first did not forsake him; for he appeared to them alive again the third day; as the divine prophets had foretold these and ten thousand other wonderful things concerning him. And the tribe of Christians, so named from him, are not extinct at this day.�
Our surviving sources for this passage are Greek manuscripts, the oldest of which dates from the 9th century. However there are citations in other writers of antiquity.
The first to cite this passage of Antiquities was Eusebius writing in about A.D. 324, who quotes the passage in essentially the same form. So it is clear that this passage existed in manuscripts of the Antiquities of the Jews at that time.
However, it is significant that Origen writing in about A.D. 240, fails to mention it, even though he does mention the less significant reference to Jesus as brother of James that occurs later in Antiquities of the Jews (book 20, ch. 9). This has given rise to the suggestion that the Testimonium Flavianum did not exist in the earliest copies, or did not exist in that form.
Those historians disposed to reject the passage suggest that passage 3.2 runs directly into passage 3.4, and that the thread of continuity is interrupted by this passage. The passage 3.3 also is supposed to fails a standard test for authenticity, in that it contains vocabulary not otherwise used by Josephus, according to the Complete Concordance to Flavius Josephus, edited by K. H. Rengstorf, 2002. Consequently these historians dismiss the Testimonium as an interpolation. It is also argued that 'He was [the] Christ.' can only be read as a profession of faith. If so, this could not be right, as Josephus was not a Christian.
the theologian Origen (about 185-254 AD) said that Josephus did not believe Jesus was the Messiah (Contra Celsum, 1:47). Edwin M. Yamauchi, Ph.D., says of this text, " Today there's a remarkable consensus among both Jewish and Christian scholars (religious sources. Unreliable) that the passage as a whole is authentic
Another writer, from around 52 AD, was Thallus. None of his works are extant, but some fragments are preserved by other writers. One was Julius Africanus, who wrote about 221(unreliable. Julius Africanus is writing about what about Thallus said 200 years later. How can anyone trust that as proof. Where are these origional writings of Thallus. Thallus works have been tampered with by Christians. Unreliable). He says:
"On the whole world there pressed a most fearful darkness; and the rocks were rent by an earthquake, and many places in Judea and other districts were thrown down. This darkness Thallus, in the third book of his History calls, as appears to me without reason, an eclipse of the sun." (Extant Writings, 18 in the Ante-Nicene Fathers) (Nowhere in the ancient world did anyone record an eclipse at this time except here and in the bible? Strange).
