Celestial Kingdom

On February 16, 1832, in Hiram, Ohio, Joseph Smith and Sidney Rigdon reported receiving a vision together while working on a revision of the Bible, prompted, according to Smith's own account, by a question that arose while they were reading John 5:29 about a resurrection to life and a resurrection to damnation. What they described afterward, recorded as Doctrine and Covenants section 76 and often simply called the Vision, expanded a two-part afterlife into a graded structure of three kingdoms of glory, each compared in the text's own language to a different heavenly body: the Celestial to the sun, the Terrestrial to the moon, and the Telestial to the stars, echoing a comparison Paul makes in 1 Corinthians 15 without spelling out three named destinations the way the revelation does.

The Celestial Kingdom, in this account, receives those who accept the fulness of the gospel, are baptized by proper priesthood authority, and continue faithful, becoming, in the revelation's language, gods themselves, sons and daughters of God with all that the Father has. It was a striking departure from the era's more common Protestant framework of a single heaven and hell, and Smith later described the vision itself, along with a companion 1836 vision recorded in section 137 concerning who would ultimately be saved, as having reshaped his own understanding of the scope of salvation available to different kinds of people, including those who die without ever hearing the gospel preached.

Within Latter-day Saint doctrine, simply qualifying for the Celestial Kingdom is not the same as receiving its highest blessing. Section 131 of the Doctrine and Covenants, recorded a decade after the original vision, teaches that the Celestial Kingdom itself contains three further degrees, and that reaching the highest of the three, called exaltation, requires a person to have entered the new and everlasting covenant of marriage, sealed for eternity rather than only for mortal life, typically inside a temple. Without that sealing, the revelation states, a person may still inherit a glory within the Celestial Kingdom but cannot receive its full increase, phrased in the text as being unable to have an increase of posterity in the eternities that follow.

For members, this doctrine is why temple marriage carries weight beyond a wedding ceremony: it is presented as the ordinance that makes exaltation, the fullest possible destiny the faith describes, available at all. Families sealed in this way are taught that the relationship can continue as an eternal unit rather than ending at death, framed by the church as one of the most distinctive and consequential differences between Latter-day Saint theology and the theology of most other Christian traditions, most of which do not treat marriage as an ordinance capable of extending past the grave.
