It follows that it is hopeless to attempt to understand the sacrificial teaching of the Old Testament without some grasp of the meaning of sacrifice in the ancient world. Failure to attain this has led to the idea that the sacrifice of Christ must mean the appeasing of an offended Deity by blood and death. But this view of sacrifice is not merely a heathen, but a late and debased heathen conception. "Shall I give my first-born for my transgression, the fruit of my body for the sin of the soul?" was the cry of the King of Moab, and it marks the lowest depth into which the pagan idea of sacrifice had sunk. It is a genuine instance of deterioration in ethnic religion. The primitive view was far loftier and more spiritual than this. Recent researches, dependent on the comparative method, into the earliest forms of religion have brought to light two principles which underlay the conception of sacrifice, and which to a great extent can be discerned more clearly in the most ancient period than in later times. Now these two principles which, taken together, constitute the primitive theory of sacrifice, which make up the fundamental idea of it, however little prehistoric man may have been capable of giving distinct and logical expression to them, were these: 1. Death is necessary to the attainment of the fulness of life. 2. Man is, by his very nature, capable of sharing in, becoming a partaker of, the Divine life. The earliest known form of sacrifice is the killing of the sacred animal of the tribe, the animal which was held to be the representative of the tribal god, followed by the sacred tribal meal upon the victim. There, in this earliest _totem_ rite, we have already implicit the two great ideas of sacrifice, the communion of man with God by actual participation in the Divine life (the feast on the sacrifice), and that this communion is rendered possible by the death of the sacred victim. These ideas were very largely obscured in ancient times by the conception of sacrifice as a gift, a tribute, or a propitiation. But these ideas, though they bulk largely in modern minds unacquainted with the recent researches of specialists in comparative religion, were, in fact, of later growth. They are accretions which, by a very natural and intelligible process, have overlain the oldest and really fundamental ideas which lie at the root and origin of sacrifice.
