But if it not be true, the myth itself requires to be explained, and every principle of philosophy and common sense demand that the explanation be sought, not in arbitrary allegorical categories, but in the actual facts of ritual or religious custom to which the myth attaches.

Even the highest forms of sacrificial worship present much that is repulsive to modern ideas, and in particular it requires an effort to reconcile our imagination to the bloody ritual which is prominent in almost every religion which has a strong sense of sin.

But, strictly speaking, this mythology was no essential part of ancient religion, for it had no sacred sanction and no binding force on the worshippers.
