Zaffiroborant,
Here is the support, straight from pure doctrinal sources:
Moses 1:6 And I have a work for thee, Moses, my son; and thou art in the similitude of mine Only Begotten; and mine Only Begotten is and shall be the Savior, for he is full of grace and truth; but there is no God beside me, and all things are present with me, for I know them all…
32 And by the word of my power, have I created them, which is mine Only Begotten Son, who is full of grace and truth.
33 And worlds without number have I created; and I also created them for mine own purpose; and by the Son I created them, which is mine Only Begotten.
Moses 2:1 And it came to pass that the Lord spake unto Moses, saying: Behold, I reveal unto you concerning this heaven, and this earth; write the words which I speak. I am the Beginning and the End, the Almighty God; by mine Only Begotten I created these things; yea, in the beginning I created the heaven, and the earth upon which thou standest.
Moses 5:9 And in that day the Holy Ghost fell upon Adam, which beareth record of the Father and the Son, saying: I am the Only Begotten of the Father from the beginning, henceforth and forever, that as thou hast fallen thou mayest be redeemed, and all mankind, even as many as will.

57 For they would not hearken unto his voice, nor believe on his Only Begotten Son, even him whom he declared should come in the meridian of time, who was prepared from before the foundation of the world.
Moses 6:52 And he also said unto him: If thou wilt turn unto me, and hearken unto my voice, and believe, and repent of all thy transgressions, and be baptized, even in water, in the name of mine Only Begotten Son, who is full of grace and truth, which is Jesus Christ, the only name which shall be given under heaven, whereby salvation shall come unto the children of men, ye shall receive the gift of the Holy Ghost, asking all things in his name, and whatsoever ye shall ask, it shall be given you.
D & C 76:13 Even those things which were from the beginning before the world was, which were ordained of the Father, through his Only Begotten Son, who was in the bosom of the Father, even from the beginning;…
25 And this we saw also, and bear record, that an angel of God who was in authority in the presence of God, who rebelled against the Only Begotten Son whom the Father loved and who was in the bosom of the Father, was thrust down from the presence of God and the Son,…
Alma 5: 48
48 I say unto you, that I know of myself that whatsoever I shall say unto you, concerning that which is to come, is true; and I say unto you, that I know that Jesus Christ shall come, yea, the Son, the Only Begotten of the Father, full of grace, and mercy, and truth. And behold, it is he that cometh to take away the sins of the world, yea, the sins of every man who steadfastly believeth on his name.
Alma 9: 26
26 And not many days hence the Son of God shall come in his glory; and his glory shall be the glory of the Only Begotten of the Father, full of grace, equity, and truth, full of patience, mercy, and long-suffering, quick to hear the cries of his people and to answer their prayers.
I think you may have noticed when I responded to BartBurk that I had not thought in much depth about the differentiation between “Only Begotten Son in the flesh” and “Only Begotten Son”. I had thought I was making it clear, and if not then I hope I am making it clear to you now that I believe the words as given in the scriptures–the Bible as well as those cited above–give true doctrine, and the words “in the flesh” are not included and thus there is a differentiation that means more than “in the flesh.” The words mean exactly what they say.
As far as Zipporah, anyone who simply goes to the internet looking for religious truth is going to be “tossed to and fro, and carried about with every wind of doctrine” and until anyone in that kind of situation sincerely seeks the voice of the Good Shepherd and the confirming influence of the Holy Ghost, then nothing I would write in this forum would help them past a smidgen and they would still be “carried about with every wind of doctrine” until such time as they stopped using the internet as their source.
Reminder to other readers: please, when reading words that are sacred language talking about God and His Son, do so with reverence toward using those words–I assume most feel that reverence but it is hard to convey in a conversation without the personal voice being heard by the reader. Peace to all.
