 In spite of the majority opinion of modern  scholars,[1]  Abner probably was not a Kabbalist before his conversion to Christianity. This mistake is based essentially on two sources: the fact that some of Abner’s arguments for the Trinity and Incarnation can be interpreted as deriving from Kabbalistic sources, and the existence of another Rabbi Abner (not a common name for Jews of his time), a Kabbalist whom Rabbi Isaac of Acre cited many times. In my opinion, Abner’s argument for the Trinity and Incarnation is not based on Kabbalistic sources, but stems from his Neo-Platonic and standard Christian scriptural  background.[2]  Additionally, Abner (the apostate) did not use many important Kabbalistic  sources.[3]  His opinions are not the same as the other Rabbi Abner’s (the one that Rabbi Isaac of Acre quotes), and we can see that the two authors do not share the same background, nor do they use the same sources, with Abner utilizing almost entirely sources taken from the Jewish philosophical and traditional rabbinic  corpuses.[4]  almost all of Rabbi Abner’s sources are taken from the commentary of Nahmanides to the Torah, a book that Abner the apostate almost never quoted.
