Joseph Smith had another opinion:
“God: Creator And Ruler Of Many Worlds. — While it is true that evolutionists may be divided between theistic and atheistic groups, yet most of those professing belief in God consider him to be an indefinable force, essence, or power of an incomprehensible nature. According to revelation, however, he is a personal Being, a holy and exalted Man, a glorified, resurrected Personage having a tangible body of flesh and bones, an anthropomorphic Entity, the personal Father of the spirits of all men. (D. & C. 130:22- 23; Moses 6:51, 57; Abra. 3:22-24; Jos. Smith 2:16-19.)”
So as not to seem to be a tricky “anti” the answer to the question posed is Yes.
“God: Creator And Ruler Of Many Worlds. — While it is true that evolutionists may be divided between theistic and atheistic groups, yet most of those professing belief in God consider him to be an indefinable force, essence, or power of an incomprehensible nature. According to revelation, however, he is a personal Being, a holy and exalted Man, a glorified, resurrected Personage having a tangible body of flesh and bones, an anthropomorphic Entity, the personal Father of the spirits of all men. (D. & C. 130:22- 23; Moses 6:51, 57; Abra. 3:22-24; Jos. Smith 2:16-19.)”
FYI, the above passage does not say that God was ever a sinful man. Just as Christ was born and became a man, though he was still God, He was sinless. Christ is a resurrected Personage having a tangible body of flesh and bones.
If you also believe that Christ(God) became man, then why is it a problem if Mormons say the same of God the Father? If you believe that Christ and the Father are one being, then you technically also believe that God the Father became a man and was resurrected but did not sin. Saying that only Chirst became a man would be like saying my left foot became a Baptist but the rest of me is a Mormon.
