At the time of the coming of Christ, ‘They who have slept in their graves shall come forth, for their graves shall be opened; and they also shall be caught up to meet him in the midst of the pillar of heaven—They are Christ’s, the first fruits, they who shall descend with him first, and they who are on the earth and in their graves, who are first caught up to meet him; and all this by the voice of the sounding of the trump of the angel of God’ [ D&C 88:97–98]. These are the just, ‘whose names are written in heaven, where God and Christ are the judge of all. These are they who are just men made perfect through Jesus the mediator of the new covenant, who wrought out this perfect atonement through the shedding of his own blood’ [ D&C 76:68–69].
Following this great event, and after the Lord and the righteous who are caught up to meet him have descended upon the earth, there will come to pass another resurrection. This may be considered as a part of the first, although it comes later. In this resurrection will come forth those of the terrestrial order, who were not worthy to be caught up to meet him, but who are worthy to come forth to enjoy the millennial reign… .
All liars, and sorcerers, and adulterers and all who love and make a lie, shall not receive the resurrection at this time, but for a thousand years shall be thrust down into hell where they shall suffer the wrath of God until they pay the price of their sinning, if it is possible, by the things which they shall suffer.
These are the ‘spirits of men who are to be judged, and are found under condemnation; And these are the rest of the dead; and they live not again until the thousand years are ended, neither again, until the end of the earth’ [ D&C 88:100–101]
