EVERYTHING he provided you was both credible and accurate. You calling quotes from mormon prophets not credible moves you to an even higher level of heresy.
This book is on my bookshelf, my father recently called me to ask to borrow my copy to prepare for a talk in Sacrament Meeting because he could not use find his copy.
“Christ was Begotten by an immortal Father in the same way that mortal men are begotten by mortal fathers” (Bruce McConkie, Mormon Doctrine, 1966, pg.547).
Ezra Taft Benson was a recent LDS prophet who died about 25 years ago:
“The Church of Jesus Christ of Latter-day Saints proclaims that Jesus Christ is the Son of God in the most literal sense. The body in which He performed His mission in the flesh was sired by that same Holy Being we worship as God, our Eternal Father. Jesus was not the son of Joseph, nor was He begotten by the Holy Ghost” (The Teachings of Ezra Taft Benson, pg.7).
And I cannot claim to have a specific recollection of this very lesson, but I had family home evening with my family growing up each week (including 1972) and I was taught this:
Now, we are told in scriptures that Jesus Christ is the only begotten Son of God in the flesh. Well, now for the benefit of the older ones, how are children begotten? I answer just as Jesus Christ was begotten of his father …Jesus is the only person who had our Heavenly Father as the father of his body" (Family Home Evening Manual, 1972, Joseph F. Smith, pp.125,126).
I read this book in the weeks before going on my mission:
“There is no need to spiritualize away the plain meaning of the scriptures. There is nothing figurative or hidden or beyond comprehension in our Lord’s coming into mortality. He is the Son of God in the same sense and way that we are the sons of mortal fathers. It is just that simple” (The Promised Messiah, pg.468).
And if God the Eternal Father is not the real Father of Jesus Christ, then are we in confusion; then is he not in reality the Son of God. But we declare that he is the Only Begotten of the Father in the flesh. Mary told the story most beautifully when she said that an angel of the Lord came to her and told her that she had found favor in the sight of God, and had come to be worthy of the fulfilment of the promises heretofore made, to become the virgin mother of the Redeemer of the world. She afterwards, referring to the event, said: “God hath done wonderful things unto me.” “And the Holy Ghost came upon her,” is the story, “and she came into the presence of the highest.” No man or woman can live in mortality and survive the presence of the Highest except by the sustaining power of the Holy Ghost. So it came upon her to prepare her for admittance into the divine presence, and the power of the Highest, who is the Father, was present, and overshadowed her, and the holy Child that was born of her was called the Son of God. (Bruce R. McConkie, The Promised Messiah, p.472 - p.473)
And this is from one of the few books missionaries are allowed to read on their mission:
Their testimony is that Mary’s son is God’s Son; that he was conceived and begotten in the normal way; that he took upon himself mortality by the natural birth processes; that he inherited the power of mortality from his mother and the power of immortality from his Father—in consequence of all of which he was able to work out the infinite and eternal atonement. This is their testimony as to his generation and mission. (James E. Talmage, Jesus the Christ, Ch.5, p.43)
"For Latter-day Saints, the paternity of Jesus is not obscure. He was the literal, biological son of an immortal, tangible Father and Mary, a mortal woman (see Virgin Birth). Jesus is the only person born who deserves the title “the Only Begotten Son of God” (John 3:16; Benson, p. 3; see Jesus Christ: Only Begotten in the Flesh). He was not the son of the Holy Ghost; it was only through the Holy Ghost that the power of the Highest overshadowed Mary (Luke 1:35; 1 Ne. 11:19).
