Was sacrifice in its origin "a human invention or a divine institution; and whether any of the sacrifices before the law, or under the law, were sacrifices of expiation. Eminent and numerous are the authorities on both sides of these questions; but the balance of theological opinion preponderated greatly for the affirmative in each of them. On the lower point, however, (viz., were the sacrifices sacrifices of expiation) most of those who deny that there was an expiatory sacrifice before the law, admit its existence under the law; and on the first, those who hold that sacrifice was of divine origin, but became much corrupted, and was restored by the Mosaic law, do not in substance differ much from those who hold it to have been a human invention, formally recognized, and remodelled by the law of Moses." Kitto's "Cyclopedia of Biblical Literature," Art. "Sacrifices." The difficulty and doubt in respect of both questions presented by these authorities is overcome by the passage which follows in the text from the Book of Moses.] "And Adam and Eve, his wife, called upon the name of the Lord, and they heard the voice of the Lord from the way toward the Garden of Eden, speaking unto them, and they saw him not; for they were shut out from his presence. And he gave unto them commandments, that they should worship the Lord their God, and should offer the firstlings of their flocks, for an offering unto the Lord.[A] And Adam was obedient unto the commandments of the Lord. 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 forevermore. And in that day the Holy Ghost fell upon Adam, which beareth record of the Father and the Son, saying: I am the only begotten of the Father from the beginning, henceforth and forever, that as thou hast fallen thou mayest be redeemed, and all mankind, even as many as will."
