Will the Levites offer a literal blood sacrifice again in the last days? Has this already been performed?
Doctrine and Covenants 13:1 states:
Upon you my fellow servants, in the name of Messiah I confer the Priesthood of Aaron, which holds the keys of the ministering of angels, and of the gospel of repentance, and of baptism by immersion for the remission of sins; and this shall never be taken again from the earth, until the sons of Levi do offer again an offering unto the Lord in righteousness.
About this scripture, Joseph Smith taught:
“It is generally supposed that sacrifice was entirely done away when the Great Sacrifice [i.e.,] the sacrifice of the Lord Jesus was offered up, and that there will be no necessity for the ordinance of sacrifice in the future; but those who assert this are certainly not acquainted with the duties, privileges and authority of the Priesthood, or with the Prophets.
“The offering of sacrifice has ever been connected and forms a part of the duties of the Priesthood. It began with the Priesthood, and will be continued until after the coming of Christ, from generation to generation. …
“These sacrifices, as well as every ordinance belonging to the Priesthood, will, when the Temple of the Lord shall be built, and the sons of Levi be purified, be fully restored and attended to in all their powers, ramifications, and blessings. This ever did and ever will exist when the powers of the Melchizedek Priesthood are sufficiently manifest; else how can the restitution of all things spoken of by the Holy Prophets be brought to pass. It is not to be understood that the law of Moses will be established again with all its rites and variety of ceremonies; this has never been spoken of by the prophets; but those things which existed prior to Moses’ day, namely, sacrifice, will be continued.” (Teachings,pp. 172–73.)
To our knowledge this has not occurred. President Joseph Fielding Smith explained that:
“ . . . we are living in the dispensation of the fulness of times into which all things are to be gathered, and all things are to be restored since the beginning. Even this earth is to be restored to the condition which prevailed before Adam’s transgression. Now in the nature of things, the law of sacrifice will have to be restored, or all things which were decreed by the Lord would not be restored. It will be necessary, therefore, for the sons of Levi, who offered the blood sacrifices anciently in Israel, to offer such a sacrifice again to round out and complete this ordinance in this dispensation. Sacrifice by the shedding of blood was instituted in the days of Adam and of necessity will have to be restored.
“The sacrifice of animals will be done to complete the restoration when the temple spoken of is built; at the beginning of the millennium, or in the restoration, blood sacrifices will be performed long enough to complete the fulness of the restoration in this dispensation. Afterwards sacrifice will be of some other character.” (Doctrines of Salvation, 3:94.)
