Question: How do LDS temple covenants relate to biblical covenants such as the Sinai Covenant, Davidic Covenant, and Abrahamic Covenant that appear so prominently in the theology of Isaiah?
Answer: While temple covenants are in the nature of individual covenants that Latter-day Saints make, the covenant made at baptism—in which we take upon ourselves the name of Jesus Christ—is in the nature of a collective covenant in which a person joins the “body of Christ.”
That covenant forms a part or extension of the Sinai Covenant, a collective covenant in which Israel elected to become a people of God. It is the same covenant King Benjamin’s people made that was an integral part of the Sinai Covenant, yet taking upon themselves the name of Christ.
At Jesus’ coming to the Nephites, that covenant developed further, beyond the Law of Moses, until—with the restoration of the gospel through the prophet Joseph Smith—it ultimately grew into what we know today as membership in the Church of Jesus Christ of Latter-day Saints.
Individual temple covenants, on the other hand, are manifestations of both the Davidic and Abrahamic Covenants and depend on a person’s faithfulness in keeping the covenants’ terms. Understanding these biblical covenants goes a long way toward understanding temple covenants.
In regards to your post: How do LDS temple covenants relate to biblical covenants such as the Sinai Covenant, Davidic Covenant, and Abrahamic Covenant that appear so prominently in the theology of Isaiah?
I do not see in the Sinai Covenant, Davidic Covenant, or Abrahamic Covenant anything that would lead me to believe that it was right to consecrate ourselves to an institution. In your opinion how does the covenant of consecration as given in our present day temple endowment have any relation to these biblical covenants?
