The great religious teachers are men who see the spiritual landscape from a certain point of view, including whatever is visible from their station, excluding whatever is not. The religion which they originate is thus both inclusive and sharply exclusive. What they see with their rapt eyes they describe with a trenchancy and fitness never thereafter to be equaled.[7] But in order to progress in religion it is necessary to advance toward a different station, to reach a different, a higher eminence, and from that to look forth anew upon the spiritual landscape, comprehending the outlook of one’s predecessors in a new perspective, seeing what they saw and much besides. Religious growth may also be compared to the growth of a tree. To expect that development shall continue along the Hebrew or Christian lines is like expecting that a tree will continue to develop along one of its branches. There is a limit beyond which the extension of a branch cannot go. Then growth must show itself in the putting forth of a new branch. But let me now state with somewhat greater particularity the reasons that compelled me to depart from the faith of Israel, and to leave my early religious home, cherishing pious memories of it, but nevertheless firmly set in my course towards new horizons.[8] 1. The difficulty created by the claim that Israel is an elect people, that it stands in a peculiar relation to the Deity. This claim, at the time when it was put forth, was neither arrogant nor unfounded. It was not arrogant because the mission was understood to be a heavy burden not a privilege: or if a privilege at all, then the tragic privilege of martyrdom, a martyrdom continued through generations. And the claim was not unfounded or preposterous at the time when it was put forth because the Hebrews were in reality the only people who conceived of morality in terms of holiness. It was not absurd for them to assert their mission to be the teachers of mankind in respect to the spiritual interpretation of morality, since there was something, and that something infinitely important, which they actually had to teach. Moral thinking and moral practices of course had existed from immemorial times everywhere, but the conception of morality as divine in its source, as spiritual in its inmost essence,—this immense idea was the offspring of the Hebrew mind. On the other hand, I asked myself, has not the task of Israel in this respect been accomplished? Have not its Scriptures become the common property of the civilized nations? And does not that teacher mistake his office who attempts to maintain his magisterial authority after his pupils have come to man’s estate, and are capable of original contributions? The “nations” are not to be looked upon in the light of mere pupils. The ethical message of Israel so far as it is sane is universalistic. It is founded on the conviction that there is a moral nature in every human being, and that the moral nature is a spiritual nature.
