Sexuality has a prominent role within the theology of The Church of Jesus Christ of Latter-day Saints (LDS Church), which teaches that gender is defined in the premortal existence, and that part of the purpose of mortal life is for men and women to be sealed together, forming bonds that allow them to progress eternally together in the afterlife. It also teaches that sexual relations within the framework of opposite-sex marriage is healthy, necessary, and ordained of God. In contrast with some orthodox Christian movements, sexuality in the Church's theology is neither a product of original sin nor a "necessary evil".
