Thanks. If you want to really blow your mind, read this article and think about how all religiously observant Jewish teachers today are descended from the Pharisees, how the Pharisees became known as rabbis, and indirectly why Jewish people feel pretty darn offended when Christians routinely trash Pharisees, whom the Jews largely regard as heroes for having guarded the practice of their faith after the destruction of the second temple.
