There remains open the fascinating problem as to whether some if not all of the more notable teachings may not be the utterances of one teacher of commanding originality, whose sectaries were either unable to appreciate or unable to keep separate his doctrine. [862] Undoubtedly some of the better teachings came first from men of superior capacity and relatively deep ethical experience. The veto on revenge, and the inculcation of love to enemies, could not come from commonplace minds; and the saying preserved from the Gospel According to the Hebrews, "Unless ye cease from sacrificing the wrath shall not cease from you," has a remarkable ring. [863] But when we compare the precept of forgiveness with similar teachings in the Hebrew books and the Talmud, [864] we realize that the capacity for such thought had been shown by a number of Jewish teachers, and that it was a specific result of the long sequence of wrong and oppression undergone by the Jewish people at the hands of their conquerors. The unbearable, consuming pain of an impotent hate, and the spectacle of it in others--this experience among thoughtful men, and not an unconditioned genius for ethic in one, is the source of a teaching which, categorically put as it is in the gospels, misses its meaning with most who profess to admire it; the proof being the entire failure of most Christians in all ages to act on it. To say nothing of similar teaching in Old Testament books and in the Talmud, we have it in the most emphatic form in the pre-Christian "Slavonic Enoch." [865]
