These requirements of relative perfection on the part of the victim were in accord with the fact that the slaughter of animals as a priestly rite by Divine direction was in pre-figurement of the then future sacrifice of the Christ Himself, whose atoning death would mark the consummation of His ministry in mortality. While the animal victims slain on Israel's altars figuratively bore the sins of the people, who by their observance of the sacrificial rite sought propitiation for their offenses, or reconciliation with God, from whom they had become estranged through transgression, Jesus Christ actually bore the burden of sin and provided a way for a literal reconciliation of sinful man to God. The principal sacrifice in the Mosaic dispensation was that of the Passover; and the superseding of the type by the actual is forcefully expressed by Paul: "For even Christ our pass-over is sacrificed for us." (1 Cor. 5:7.) Theologians, Bible scholars generally, and ethnologists as well, admit the absence of all record both in the Bible and in profane history concerning the origin of sacrifice. The writer of the article "Sacrifice" in one of our Bible Dictionaries (Cassell's), which article is in line with other learned commentaries, says, following an array of facts: "On these and other accounts it has been judiciously inferred that sacrifice formed an element in the primeval worship of man; and that its universality is not merely an indirect argument for the unity of the human race, but an illustration and confirmation of the first inspired pages of the world's history. The notion of sacrifice can hardly be viewed as a product of unassisted human nature, and must therefore be traced to a higher source and viewed as a Divine revelation to primitive man." That "Divine revelation to primitive man" is now before the world; and the much-talked-of historical difficulty as to the origin of sacrificial rites is definitely solved by revelation from God to man in the current age, whereby parts of the ancient Scriptures not contained in the Bible have been restored to human knowledge. As the natural and inevitable consequence of his transgression, Adam forfeited the high privilege of holding direct and personal association with God. In his fallen state the man was commanded by the voice of the Lord to offer in sacrifice the firstlings of his flocks. "And after many days an angel of the Lord appeared unto Adam, saying: Why dost thou offer sacrifices unto the Lord? And Adam said unto him: I know not, save the Lord commanded me. And then the angel spake, saying: This thing is a similitude of the sacrifice of the Only Begotten of the Father, which is full of grace and truth. Wherefore, thou shalt do all that thou doest in the name of the Son, and thou shalt repent and call upon God in the name of the Son for evermore." (Pearl of Great Price, p.20.)
