Links please. I've certainly never heard any reputable source call Josephus a fraud.
Josephus isn't a fraud, the passage alleging Jesus is a fraud put into Antiquities AFTER then 9th century AD.
The passage in question translates to;
{About this time, there lived Jesus, a wise man, if indeed one ought to call him a man. For he was one who wrought surprising feats and was a teacher of such people as accept the truth gladly. He won over many Jews and many of the Greeks. He was the Messiah. When Pilate, upon hearing him accused by men of the highest standing amongst us, had condemned him to be crucified, those who had in the first place come to love him did not give up their affection for him. On the third day he appeared to them restored to life, for the prophets of God had prophesied these and countless other marvelous things about him. And the tribe of the Christians, so called after him, has still to this day not disappeared. }
{Why is this Jesus testimony considered a later insertion?
1. Josephus was a Pharisee. Only a Christian would call Jesus the Christ. Josephus would have had to renounce his pharisaical beliefs to say Jesus was the Christ. Josephus died a pharisee.
2. Josephus habitually writes chapter upon chapter about the most insignificant people and events. The Jesus testimony consists of three sentences. Why would JosephusÂ’ Christ be given only three brief sentences? ?
3. The paragraphs before and after the Jesus testimony describe Romans killing Jews. The paragraph following the Jesus testimony begins "About the same time another sad calamity put the Jews in disorder". Would the "sad calamity" refer to the appearing of the "doer of wonderful works" or Romans killing Jews? The Jesus Testimony is clearly out of context having every appearance of a later insertion.
4. Finally, and most convincing had Josephus actually written the Jesus testimony, church fathers in the following 200 years would surely refer to it in fending off critics of JesusÂ’ being just another myth. But, not once does Justin, Irenaeus, Tertullian, Clement of Alexandria, or Origen ever refer to JosephusÂ’ Jesus testimony. We know Origen read Josephus because OrigenÂ’s writings criticize Josephus for attributing the destruction of Jerusalem to the killing of James rather then Jesus. The church fathers made no reference to JosephusÂ’ Jesus testimony because Josephus never wrote it.}
