Rav Avraham Abulafia's approach to Jesus is important because it establishes a certain amount of legitimacy to him within the context of Torah.

I mean, people can think of lots of things, but those things are not necessarily with the context or borders of Authentic Torah.  In fact, most of what passes today as authentic Torah is anything but that.

[Rishonim means "first ones" [After Rav Hai Gaon until Rav Joseph Karo as opposed to Ahronim ["later ones"--after Rav Joseph Karo.]
