Mormonism teaches:
Heavenly Father/Elohim
Jesus Christ/Jehovah
Holy Ghost
D. God is the Supreme Being in the universe.
1. God the Father is greater than all (see Ephesians 4:6; John 10:29).
2. As the Supreme Being, God the Father should be the object of our love and worship (see D&C 18:40; 20:29; Joshua 22:5; Mark 12:30; D&C 4:2; Luke 4:8).
3. God created all things through His Son (see Hebrews 1:12; Moses 1:3233; 2:1).
E. The Father presides over the Godhead.
1. The Father, the Son, and the Holy Ghost are the members of the Godhead (see Articles of Faith 1:1; 1 John 5:7; Alma 11:44).
2. Each member of the Godhead is physically separate and distinct from the others (see D&C 130:22; Matthew 3:1617; Acts 7:5556).
3. The members of the Godhead are united in Their attributes, power, and purpose (see John 17:2021; D&C 20:28; 35:2; 2 Nephi 31:21; 3 Nephi 11:27).
4. The Father is the supreme member of the Godhead (see John 14:26, 28, 31; 2 Nephi 31:7, 12; 3 Nephi 28:11).

B. God is the father of all mankind.
1. ■ God the Eternal Father, whom we designate by the exalted name-title Elohim, is the literal Parent of our Lord and Savior Jesus Christ, and of the spirits of the human race (The Father and the Son: A Doctrinal Exposition by the First Presidency and the Twelve, in James E. Talmage, The Articles of Faith, 466).
If you concede that we are His children, you must allow that God is our Father (Boyd K. Packer, in Conference Report, Oct. 1984, 82; or Ensign, Nov. 1984, 6667).
■ God made man in his own image and certainly he made woman in the image of his wife-partner (Spencer W. Kimball, The Teachings of Spencer W. Kimball, 25).
C. God is perfect in His person, character, and attributes.
D. God is the Supreme Being in the universe.
E. The Father presides over the Godhead.

■ Everlasting covenant was made between three personages before the organization of this earth, and relates to their dispensation of things to men on the earth; these personages, according to Abrahams record, are called God the first, the Creator; God the second, the Redeemer; and God the third, the witness or Testator (Smith, Teachings, 190).
