Give me a break:
As I wrote in my post, I think it’s the RamBam who added the last level, “Yisroel”.(but I’m not sure) I would be more careful before I call the Rambam an “egotistical Jew”, especially since all you’re doing is displaying your ignorance. If you have never heard of a concept, it doesn’t mean it was “made up.”
This is a concept i learned in school several times, but since i’m out of school for a while, I don’t remember the source. Maybe some of the Talmidei chachamim on this blog can help me out here and take “Mr. break” out of his ignorance. I will also, bez”h try to research it.
