Isaac of Troki (AD 1533-1594)

The defunct unofficial CSBRQA's Chancellery's ex-Chairman Libor (Nissim ben Abraham" Valko's "European Karaite Judaism" and other such groups promote a book about Judaism called "Hizzuk Emunah"  (Faith Fortified) which academics have alleged was authored by Isaac Troki. But let us consider for a moment, how do we know that book was written by Isaac Troki? The simple answer is that we don't! Moreover there is plenty in that book which can be used to show that it was not written by Karaites at all! For example:

1.) The book makes not even one reference to the sevel ha-Yerushah, nor to Anan ben David, nor to Karaites nor any background about Isaac Troki.
2.) Although reflecting Karaite opposition to the apostles, it does not at all reflect the uniquely Karaite traditions on Christ's reincarnation as his own step-nephew, HaNotzri Ben Pandera who lived during the reign of Queen Helene of Adiabene and her sons Monobazuz and Constantine Izates. It is very strange that the only substantial alleged Karaite critique on the alleged work of HaNotzri would overlook all mention of what is perhaps the most uniquely Karaite tradition surrounding the issue. As Shapshal made clear, Jesus was an human Christ but never as a divine Messias. A Mashiakh but not the Moshia'. We are the Minim followers of Christ's reincarnation HaNotzri and who survived the attempts of the Rabbinical Jews to convert us away from our respect for HaNotzri into gentile Notzrim.

To be clear, despite the commissions, there is nothing in the Hizzuk Emuna which is objectionable to Karaites. Indeed it portrays the traditional Karaite position towards the accuracy of the Christian New Testament.

Stories about Zerah ben Nathan Troki and Joseph Malinovski Troki being turned away by pious Babylonian Jewish publishers could be dismissed as fictitious. 

It is likely that some work of Isaac Troki landed in the hands of a Babylonian Jew but was redacted or edited and expanded by an unknown Babylonian Jewish author who sought to protect his fellow Babylonian Jews from any backlash by attributing it to the small but fierce, isolated, fortified, warrior community of Judaized Gazarians who were anyway despised as heretics by Babylonian Judaism. Secondly that if it did not result in any backlash then the Judaized Gazarians of Troki might be pushed all the way into full mainstream Ashkenazi conversions if they believed this was a posthumous work of one of their own sages. Blaming the book on a Khazar called Isaac Troki was a win win situation... 

...and the Khazars have been blamed for everything else ever since!
