Holy Ghost

The third member of the Godhead (1 Jn. 5:7; D&C 20:28). He is a personage of Spirit, not having a body of flesh and bones (D&C 130:22). The Holy Ghost is often referred to as the Spirit, or the Spirit of God.

The Holy Ghost performs several vital roles in the plan of salvation. (1) He bears witness of the Father and the Son (1 Cor. 12:3; 3 Ne. 28:11; Ether 12:41). (2) He reveals the truth of all things (John 14:26; 16:13; Moro. 10:5; D&C 39:6). (3) He sanctifies those who have repented and become baptized (John 3:5; 3 Ne. 27:20; Moses 6:64–68). (4) He is the Holy Spirit of Promise (D&C 76:50–53; 132:7, 18–19, 26).

The power of the Holy Ghost can come upon a person before baptism and witness that the gospel is true. But the right to have the constant companionship of the Holy Ghost, whenever one is worthy, is a gift that can be received only by the laying on of hands by a Melchizedek Priesthood holder after authorized baptism into the true Church of Jesus Christ.

Jesus taught that all sins could be forgiven except blasphemy against the Holy Ghost (Matt. 12:31–32; Mark 3:28–29; Luke 12:10; Heb. 6:4–8; D&C 76:34–35).
