The Church of Jesus Christ of Latter-day Saints teaches that all human beings, male and female, are beloved spirit children of heavenly parents, a Heavenly Father and a Heavenly Mother. This understanding is rooted in scriptural and prophetic teachings about the nature of God, our relationship to Deity, and the godly potential of men and women.1 The doctrine of a Heavenly Mother is a cherished and distinctive belief among Latter-day Saints.2
