Beginning with Joseph Smith’s First Vision, the true knowledge of God has been restored in our day.
I am very grateful for the 1838 account of the first vision, in which the Father and the Son appeared to the youthful prophet and again restored to man the true knowledge of God.3
Through Joseph Smith’s First Vision, “the true knowledge of God” was restored.
It should be remembered that the entire Christian world in 1820 had lost the true doctrine concerning God. The simple truth which was understood so clearly by the apostles and saints of old had been lost in the mysteries of an apostate world. All the ancient prophets, and the apostles of Jesus Christ had a clear understanding that the Father and the Son were separate personages, as our scriptures so clearly teach. Through apostasy this knowledge was lost. … God had become a mystery, and both Father and Son were considered to be one unknowable effusion of spirit, without body, parts, or passions. The coming of the Father and the Son placed on the earth a divine witness who was able by knowledge to restore to the world the true nature of God.4
The 1838 account of the [first] vision of Joseph Smith made it clear that the Father and the Son are separate personages, having bodies as tangible as the body of man. It was further revealed to him that the Holy Ghost is a personage of Spirit, distinct and separate from the personalities of the Father and the Son [seeD&C 130:22]. This all-important truth staggered the world; yet, when we consider the clear expressions of holy writ, it is a most astounding and wonderful fact that man could have gone so far astray. The Savior said, “My Father is greater than I;” [John 14:28] and he invited his disciples, after his resurrection, to handle him and see that it was he, for, said he, “A spirit hath not flesh and bones, as ye see me have.” [Luke 24:39.] The apostles clearly understood the distinct entities of the Father, Son, and Holy Ghost, to which they constantly refer in their epistles; and Paul informed the Corinthians of the fact that when all things are subjected to the Father, “then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.” [1 Corinthians 15:28.]
In the 1838 account of the first vision,Joseph Smith beheld the Father and the Son; therefore he could testify with personal knowledge that the scriptures were true wherein we read: “So God created man in his own image, in the image of God created he him; male and female created he them.” [Genesis 1:27.] This was to be understood literally, and not in some mystical or figurative sense.5
Addendum: There are several (at least 4) different recorded accounts of the first vision given by Joseph Smith, which contain some contradictory information. Although the first vision occurred in 1820, the first recitation of the vision was not documented until 12 years later in 1832 , and subsequent version were recorded in 1835 , 1838 (most common) , and 1842. The personages appearing to Joseph in these encounters are different and the significance of this is debated. In 1832, Joseph reported that two unidentified personages appeared sequential (and not simultaneously) to him, that the second verbally referenced Jesus Christ, and that he thereafter saw many angels during the vision. In 1835, Joseph recorded that “the Lord” appeared to him without mention of the Father. The 1838 account is the one most commonly known and taught, and the 1842 account records the appearance of two personages of exact likeness.Meaning: From a secular perspective the discrepancies of accounts as well the prolonged time between when the vision occurred and when the vision was reported are problematic and suggest that the vision may have been changed over time and that is certainly less important (and perhaps unknown) in the early church than it currently taught. From a faithful perspective, the discrepancies may be explained by the difficulty of retelling a story so many years later. While acknowledging that historical discrepancies exist, the later emphasis of subsequent church leaders on the 1838 rendition highlights attention on the significance the Church wants members to place on God the Father and Jesus Christ as two separate personages.References:
