The extant manuscripts of the writings of the 1st-century Romano-Jewish historian Flavius Josephus include references to Jesus and the origins of Christianity. Josephus' Antiquities of the Jews, written around 93–94 AD, includes two references to the biblical Jesus Christ in Books and and a reference to John the Baptist in Book .
Scholarly opinion varies on the total or partial authenticity of the reference in of the Antiquities, a passage that states that Jesus the Messiah was a wise teacher who was crucified by Pilate, usually called the Testimonium Flavianum. The general scholarly view is that while the Testimonium Flavianum is most likely not authentic in its entirety, it is broadly agreed upon that it originally consisted of an authentic nucleus, which was then subject to Christian expansion/alteration. Although the exact nature and extent of the Christian redaction remains unclear, there is broad consensus as to what the original text of the Testimonium by Josephus would have looked like.
Modern scholarship has largely acknowledged the authenticity of the reference in of the Antiquities to "the brother of Jesus, who was called Christ, whose name was James" and considers it as having the highest level of authenticity among the references of Josephus to Christianity.
Almost all modern scholars consider the reference in of the Antiquities to the imprisonment and death of John the Baptist also to be authentic and not a Christian interpolation.
The references found in Antiquities have no parallel texts in the other work by Josephus such as the Jewish War, written 20 years earlier, but some scholars have provided explanations for their absence. A number of variations exist between the statements by Josephus regarding the deaths of James and John the Baptist and the New Testament accounts. Scholars generally view these variations as indications that the Josephus passages are not interpolations, for a Christian interpolator would have made them correspond to the New Testament accounts, not differ from them.
