We affirm that marriage is necessary for the accomplishment of God’s plan to provide the approved setting for mortal birth and to prepare family members for eternal life. Knowledge of God’s plan gives Latter-day Saints a unique perspective on marriage and children. We look on the bearing and nurturing of children as part of God’s plan and a sacred duty of those given the power to participate in it. We believe that the ultimate treasures on earth and in heaven are our children and our posterity. And we believe that we must contend for the kind of mortal families that provide the best conditions for the development and happiness of children—all children.
