Their philosophy took its stand, as you all know, on certain ancient books of their people; histories, laws, poems, philosophical treatises, which all have one element peculiar to themselves, namely, the assertion of a living personal Ruler and Teacher, not merely of the Jewish race, but of all the nations of the earth. After the return of their race from Babylon, their own records give abundant evidence that this strange people became the most exclusive and sectarian which the world ever saw. Into the causes of that exclusiveness I will not now enter; suffice it to say, that it was pardonable enough in a people asserting Monotheism in the midst of idolatrous nations, and who knew, from experience even more bitter than that which taught Plato and Socrates, how directly all those popular idolatries led to every form of baseness and immorality. But we may trace in them, from the date of their return from Babylon, especially from their settlement in Alexandria, a singular change of opinion. In proportion as they began to deny that their unseen personal Ruler had anything to do with the Gentiles—the nations of the earth, as they called them—in proportion as they considered themselves as His only subjects—or rather, Him and His guidance as their own private property—exactly in that proportion they began to lose all living or practical belief that He did guide them. He became a being of the past; one who had taught and governed their forefathers in old times: not one who was teaching and governing them now. I beg you to pay attention to this curious result; because you will see, I think, the very same thing occurring in two other Alexandrian schools, of which I shall speak hereafter.
