In the Journal of Discourses, volume 1, page 46, is a sermon by President Brigham Young, from which the following extract is taken:

Now hear it, O inhabitants of the earth, Jew and Gentile, Saint and sinner! When our father Adam came into the garden of Eden, he came into it with a celestial body * *

When Adam and Eve had eaten of the forbidden fruit, their bodies became mortal from its effects, and therefore their offspring were mortal.

This declaration is generally accepted by leading men in our Church. A celestial body is a resurrected body (although a resurrected body does not necessarily belong to the celestial order); and the statement that Adam had Eve possessed immortal bodies, not subject to death, corresponds perfectly with the terms of the law which they broke, quoted above. One correspondent, with a show of impatience, declares it a contradiction of terms to say that Adam was immortal but became subject to death. Adam was immortal had he chosen to remain so, and he never would have died had he not so consented. The fact that he was immortal did not destroy his agency; it was his privilege to do that which would render him mortal. The Pearl of Great Price makes this clear:

Nevertheless thou mayest choose for thyself, for it is given unto thee, but remember that I forbid it. (Moses 3:17.)

When Adam and Eve left the celestial sphere in which they had formerly dwelt, and with their resurrected bodies took up their abode in the Garden of Eden, they lost the knowledge and intelligence they had formerly possessed, and, intellectually and spiritually, became as little children. It was the same with Jesus. When He left the courts of glory to dwell in the flesh He became as other mortal children in respect to the knowledge He had formerly possessed. "In His humiliation His judgment was taken away." (Acts 8:33.)
