The Church of Jesus Christ of Latter-day Saints
Members of the Church of Jesus Christ of Latter-day Saints (LDS Church) believe that the Holy Ghost is the third member of the Godhead, and is a personage of spirit, without a body of flesh and bones. Unlike in many other denominations, the term "Holy Ghost" remains much more common than "Holy Spirit" in LDS contexts. Nevertheless, the Holy Ghost is sometimes referred to as the Spirit, the Holy Spirit, the Spirit of God, the Spirit of the Lord, or the Comforter. Latter-day Saints believe in a kind of social trinitarianism and subordinationism, meaning that the Father, the Son, and the Holy Ghost are understood as being unified in will and purpose, but not in substance. The Holy Ghost is believed to be subordinate to the Father and the Son and operates under their direction. The Holy Ghost, like all intelligent beings, is believed to be fundamentally eternal, uncreated, and self-existent.
