Our faith has its root in the word of God recorded in Genesis 1:2 (Inspired Version) "I am the Beginning and the End; the Almighty God. By mine Only Begotten I created these things."
A series of lectures were delivered by the Prophet Joseph Smith, Jr. to the priesthood of the Church prior to the Kirtland endowment of 1836 and were published as part of the Doctrine and Covenants until 1894. They were known as the Lectures of Faith. In these lectures the prophet had the following to say about God and the Godhead:
"We here observe that God is the only supreme governor and independent being in whom all fullness and perfection dwells; who is omnipotent, omnipresent, and omniscient; without beginning of days or end of life; and that in him every good gift, and every good principle dwells; and that he is the Father of Lights. In him the principle of faith dwells independently; and he is the object in whom the faith of all other rational and accountable beings center for life and salvation." (Lectures Of Faith, section 2, p. 12)
Joseph Smith, Jr. went on to describe the character of God as:
"First, that he was God before the world was created, and the same God that he was after it was created. Second, that he is merciful and gracious, slow to anger, abundant in goodness, and that he was so from everlasting, and will be to everlasting. Third, that he changes not, neither is there variableness with him; but that he is the same from everlasting to everlasting, being the same yesterday, today, and forever; and that his course is one eternal round, without variation. Fourth, that he is a God of Truth and cannot lie. Fifth, that he is no respecter of persons, but in every nation he that fears God and works righteousness is accepted of him. Sixth, that he is love." (Lectures Of Faith, section 3, p.52)
The prophet said that when we speak of the Godhead we mean the Father, Son, and Holy Ghost. He further said:
"There are two personages who constitute the great, matchless, governing, and supreme power over all things—by whom all things were created and made that are created and made, whether visible or invisible; whether in heaven, on earth, or in the earth, under the earth, or throughout the immensity of space. They are the Father and the Son: the Father, a personage of spirit, glory, and power, possessing all perfection and fullness. The Son, who was in the bosom of the Father, a personage of tabernacle, made or fashioned like unto man, or being in the form and likeness of man, or rather, man was formed after his likeness and in his image. He is also the express image and likeness of the personage of the Father, possessing all the fullness of the Father, or the same fullness with the Father, being begotten of him; and was ordained from before the foundation of the world to be a propitiation for the sins of all those who should believe on his name; and is called the Son because of the flesh—and descended in suffering below that which man can suffer, or in other words, suffered greater sufferings, and was exposed to more powerful contradictions than any man can be. But notwithstanding all this, he kept the law of God; and remained without sin; showing thereby that it is in the power of man to keep the law and remain also without sin. And also, that by him a righteous judgment might come upon all flesh, and that all who walk not in the law of God, may justly be condemned by the law, and have no excuse for their sins. And he being the Only Begotten of the Father, full of grace and truth, and having overcome, received a fullness of the glory of the Father—possessing the same mind with the Father; which mind is the Holy Spirit that bears record of the Father and the Son; and these three are one, or in other words, these three constitute the great, matchless, governing, and supreme power over all things; by whom all things were created and made, that were created and made; and these three constitute the Godhead and are one; the Father and the Son possessing the same mind, the same wisdom, glory, power, and fullness; filling all in all—the Son being filled with the fullness of the Mind, glory, and power; or in other words the Spirit, glory, and power of the Father—possessing all knowledge and glory, and the same kingdom; sitting at the right hand of power, in the express image and likeness of the Father—a Mediator for man—being filled with the fullness of the Mind of the Father, or in other words, the Spirit of the Father; which Spirit is shed forth upon all who believe on his name and keep his commandments; and all those who keep his commandments shall grow up from grace to grace, and become heirs of the heavenly kingdom, and joint heirs with Jesus Christ; possessing the same mind, being transformed into the same image or likeness, even the express image of him who fills all in all; being filled with the fullness of his glory, and become one in him, even as the Father, Son, and Holy Spirit are one." (Lectures Of Faith, section 5, pp. 73-75)
Joseph Smith III said, "It is impossible for finite minds to comprehend God, but when fully obedient and receiving a fullness of glory, man shall see God as he is." (Saints' Herald, Vol. 45, No. 11, 1898, p. 162)
Israel A. Smith in an article entitled "The Godhead Dogma and the 'Iron Bedstead'" warned the saints of the dangers of establishing dogma and said, "We must admit that the question of the Godhead is a difficult one. However, there is no doctrine of salvation involved." (Saints' Herald, Vol. 101, Feb. 1, 1954, p. 7). F. Henry Edwards wrote, "Distinctions within the Godhead are possibly better understood as diversities of divine operations rather than as differences in the divine nature." (Question Time, Vol.1, p. 25-26). We would be wise to trust in the word of counsel and await the day when "...if your eye be single to my glory, your whole bodies shall be filled with light, and there shall be no darkness in you, and that body which is filled with light comprehendeth all things. Therefore, sanctify yourselves that your minds become single to God, and the days will come that you shall see him: for he will unveil his face unto you, and it shall be in his own time, and in his own way, and according to his own will." (Doctrine and Covenants 85:18)
While there are many who speculate and even at times argue the nature of the Godhead we would be wise not to establish dogma but to rest our belief in harmony with the words of the prophet Joseph Smith, Jr. as preserved in the seven lectures given in the School of the Prophets at Kirtland, Ohio.
Briefly, we would say then that the Remnant Church's belief regarding the Godhead is summarized as: "...the Father, the creative genius of all; the Son, the manifestation of God in the flesh; the Holy Spirit, the manifestation of the power of God through which the Father and the Son are made comprehensible." (Question Time, Vol. 3, p. 30)
