It is indeed only a few sentences, and by suggesting there's no such passage, as some kind of a fact(!), you're turning a fringe opinion into a fact. Shameless. Fact: There is a passage of a few sentences prior to the reference to James, and it's in Chapter 18. What you've done without realizing it is leave the implication that there was originally such a passage in Chapter 18 after all, except that the original was corrupted and "sanitized". Guess what? That's the same guess we find in a whopping majority of today's professional secular scholars -- Duh.

Yet there is that report that "Vossius, in the 16th century, possessed a manuscript of Josephus which contained no mention of Jesus" and the fact that people who should have used the Testimonium Flavium didn't.
Why didn't Justin Martyr (c100 - c165), Theophilus (d. 180), Irenaeus (c120 - c203), Clement of Alexandria (c150-c215), Origen (c185-c254), Hippolytus (c170 - c235), Minucius Felix (d. c250), Anatolius (230-280), Chrysostom (c347-407), Methodius (9th century), and Photius (c820-891) use the Testimonium Flavium in their arguments against detractors?
The Greek word used in the passage for Christ is χριστος which does appear the Old Testament...the problem is that appears to mean ointment rather than anointed one. Which would leave the poor Roman audience Josephus was writing for scratching their head in befuddlement.
More over why does the passage right after the Testimonium Flavium say "And about the same time another terrible misfortune confounded the Jews ...” and the whole section flow better if you remove the Testimonium Flavium entirely?
The funny thing is when Remsburg wrote The Christ even Christian scholars were dismissing the Testimonium Flavium as a fake. How did the discovery of a 10th-century Arabic version result in such a sea change? The forgery is thought to have happened in the 4th century so a copy some six centuries older doesn't prove anything about the passage existing.
One gets less the impression of actual scholarly work and more the kind of mindset Miner satirized in a "Body Ritual among the Nacirema".
