Do all Mormons reject the idea of social mobility in the afterlife?

In Mormon theology, it is taught that Jesus Christ’s atonement guarantees the universal, physical resurrection of all humankind. When Jesus physically died on the cross his mortal suffering ceased and his spirit departed from his body. On the third day after his death his spirit re-inhabited his body and he was thereby the first to be resurrected, receiving a perfected, immortal, physical body. Mormon theology holds that all who have ever lived on earth will one day be resurrected. Following resurrection, individuals are subject to judgment by Jesus Christ as part of the Final Judgment. Mormon cosmology describes three possible post-mortem eternal realms, and that the assignment to one of these kingdoms is to be determined at the Final Judgment. These realms are called the the celestial, the terrestrial and the telestial kingdom. (Joseph Smith articulated this conception of the afterlife primarily on the basis of a vision he reportedly experienced with Sidney Rigdon in 1832. This doctrinal exposition is canonized within the Latter-day Saint scriptural corpus as section 76 of the Doctrine and Covenants.) We can succinctly describe these different realms: * The celestial kingdom is reserved for those who have lived righteously, accepted the fullness of Jesus Christ’s teachings and respected all holy covenants. \* * The terrestrial kingdom is an intermediate kingdom. It includes individuals considered honorable in their conduct yet who, during mortality, rejected the "fullness of the gospel." This rejection is explicitly attributed not to inherent malice but to external deception, characterized as being "blinded by the craftiness of men." It also includes individuals who repudiated "the testimony of Jesus in the flesh" (i.e., during their mortal lives), and accepted that testimony in the post-mortal spirit world. In the terrestrial kingdom we also find individuals who did accept the gospel testimony during their earthly lives. but failed to demonstrate sufficient commitment or zeal. * The telestial kingdom constitutes the lowest of the three degrees of glory. Its inhabitants are described as including those who, during mortal life, “received not the gospel of Christ, nor the testimony of Jesus.” It also includes "liars, and sorcerers, and adulterers, and whoremongers and cloakers". We also find murderers, and idolaters in this realm. * A small subset of individuals will not be assigned to any of these realms. Though they will be resurrected, they will be in realm or state of “outer darkness”. Those described as “sons of perdition” are traditionally portrayed as residing in this state, dwelling in company with Satan and his attendant spirits. Many ex-Mormons have reported profound existential anxiety and genuine dreaded angst at the prospect of being assigned to a different eternal dwelling place than loved ones. It is not clear to me – however – whether all Latter Day Saint movements view these assignments as eternal, or whether individuals from lower realms universally (among Mormons) are denied communication with individuals from higher-order higher-status realms. Does the LDS Church or any other Latter Day Saint movement teach a notion of possible social mobility between these realms, in the afterlife? To make it concrete: if one’s parents were assigned to the terrestrial kingdom, one’s siblings to the celestial kingdom, and one’s cousins to the telestial kingdom, according to Mormon theology, will there be any possibility of those relatives ever meeting again? Does the answer differ to this question depending on which Latter-day Saint tradition one considers? To my knowledge, the dogma of hierarchical visitation is accepted by The Church of Jesus Christ of Latter-day Saints ([D&C 88:22-24](https://www.churchofjesuschrist.org/study/scriptures/dc-testament/dc/88?lang=eng&id=22-24#22) and [D&C 76:86-88](https://www.churchofjesuschrist.org/study/scriptures/dc-testament/dc/76?lang=eng&id=86-88#85)) , but the Community of Christ has largely moved away from the literal, detailed cosmology of D&C 76 and D&C 88. --- \* "All men who become heirs of God and joint heirs with Jesus Christ will have to receive the fulness of the ordinances of his kingdom; and those who will not receive all the ordinances will come short of the fulness of that glory" – Joseph Smith
