What does Mormonism portray as the central religious experience?
Maybe its the achievement of Godhood in family, you could make an argument for that. Although that’s pretty remote and abstract. We don’t have any visuals or stories about that.
In the temple, and in our central book, the Book of Mormon, and in its central passages, the 3 Nephi narrative of Christ in the Americas, the central experience is seeing Christ, and hearing his voice, and pressing his wounds.
Note that D&C 130 (the one on marriage) implicitly combines these two.
