QUOTE : And herein lay a tension of paradox. For a high priest to sufficiently mediate between god and man, he would have to be sinless. But only a god could have such perfection. But a god could not represent man because he was wholly other, separate. Thus the repeated need for the high priest to be forgiven before he could perform his mediation. It was a weakness of the system that Caleb had thought could only be permanently overcome by a being of both deity and humanity, a kind of “god-man” that could become an eternal sacrifice. But he thought his imagination got away from him, for such a thing seemed impossible indeed.
