A question now arises of greater moment both for our present purpose and for the wider interests of Comparative Religion. Was the purport and significance of the sacrificial act the same in the Western society as that which is revealed in the sacred literature of Babylonia? No part of the ancient religious system has been the theme of so much study and speculation in recent years as the ancient sacrifice. Robertson Smith in his epoch-making book, _The Religion of the Semites_, was the pioneer of a new theory; which has since been developed or modified by certain English and a few Continental scholars following on his track. The result of these labours has been to formulate and define various forms of sacrifice that prevailed in the Mediterranean area. Three main types appear to emerge: (_a_) the gift sacrifice, where an oblation is given over entirely to the deity, whether generally to win his favour, or in special circumstances--for instance, after sin has been committed--to appease his wrath, or as a thank-offering for favour received; (_b_) the communion sacrifice, where the community or the individual eat with the deity, strengthening their feeling of fellowship by a common meal; (_c_) the sacramental type, where the community or the individual may be said to “eat the god,” that is, to partake of food or drink made sacred by the infusion of the divine spirit or personality, which is thus communicated to the partaker. It is best for the present to regard these three as separate and independent, without trying to determine which is prior and which posterior.[235.1]
