I believe that the great and fundamental heresy of the apostasy is the removal of the Father as an actual Father from Christian theology - someone His children can emulate and grow to approximate. I believe the great correction of the Restoration, imo, is the reinstatement of the Father as our ultimate, eternal objective. I believe the great addition of the Restoration is the inclusion of women in this eternal vision - by positing the existence of a Mother.
No matter the actual nature of Godhood, I believe strongly that the belief in individual exaltation and the effort required to reach perfection (completion of growth) is critical to the Atonement of Jesus as taught in the Gospels. Explicitly including women in that construct by juxtaposing a Mother at the side of a Father is deeply profound, in my humble opinion, regardless of whether it is an "accurate" depiction of the afterlife. The temple (and now "A Family: The Proclamation to the World") is a good example of how our ideal differs from the modification that is practiced in the fallen world, and too many people (even members) don't understand the power of our truly unique theology as it relates to men and women.
