My recent posts on Paul haven't proven too popular, but I'm still pursuing the topic. I noticed Elder D. Todd Christofferson's use in General Conference of terms drawn from Pauline theology to explain the LDS view of the Atonement:
Our witness is this: We know that justification, or forgiveness of sins, through the grace of our Lord and Savior Jesus Christ is just and true. And we know also that sanctification, or purification from the effects of sin, through the grace of our Lord and Savior Jesus Christ is just and true to all those who love and serve God with all their mights, minds, and strength.
Justification and sanctification — these are the terms that conservative Christians use to explain their doctrinal views. These terms don't appear in the gospels, which suggests that Jesus did not use such terms during his own ministry. It is terminology Paul employed to explain his views. Elder Christofferson appears to be making an effort to state the LDS view of the Atonement in the Pauline terms familiar to conservative Christians.
Just before the passage quoted above, Elder Christofferson explained the Atonement in terms more familiar to Latter-day Saints:
Repentance exists as an option only because of the Atonement of Jesus Christ. It is his infinite sacrifice that bringeth about means unto men that they may have faith unto repentance. Repentance is the necessary condition and the grace of Christ is the power by which mercy can satisfy the demands of justice.
In that passage, Elder Christofferson is quoting Alma 34:15 from the Book of Mormon:
And thus he shall bring salvation to all those who shall believe on his name; this being the intent of this last sacrifice, to bring about the bowels of mercy, which overpowereth justice, and bringeth about means unto men that they may have faith unto repentance.
Defining justification as "forgiveness of sins" and sanctification as "purification from the effects of sin" is just a starting point for an LDS discussion of how Paul used these terms and of how we should use these terms, which have not featured prominently in prior LDS discussion of the Atonement. For example, the doctrinal handbook True to the Faith, published by the Church, does not have entries for "justification" or "sanctification." There is a lengthy entry for "Atonement of Jesus Christ," but neither term appears anywhere in that discussion.
Did you notice any other discussions of Pauline terms or theology in Conference?
