I don't get to call heresy. The Church does; we are discussing Christianity here. Any departure from Christianity is heresy at least. For that matter, your belief that Jesus is disembodied might be considered heretical or at least mistaken by many Christians.
And? That does not make it so. Heresy is declared by the Church.
This says that Jesus is merely the Firstborn, and we are exactly as Jesus, only subordinate to Him. As Jesus was born (or created) so are all humans.
I would strike the words merely, exactly, and created. Even then, the statement would not be an adequate summary of what Mormons believe about Jesus Christ.
This is not about you. What does LDS doctrine say?
This teaches that if I attain this level, I will have my own universe and become a god over it.
I cannot find the word universe in the text of the Bible, Book of Mormon, Doctrine and Covenants, or Pearl of Great Price. The word appears in the study aids attached to the Bible, but these are not considered canonical. So far as I can tell, the idea of multiple universes is to be found nowhere in the LDS scriptures. That does not mean the idea is untrue, only that God has not revealed it to us. I would expect God to reveal it if and when He considers it important for us to know.
Neither is the term biological diversity, yet the people of that time practiced it with their animals and in their revulsion towards human incest. If one attaining the celestial heaven is to become a god and have all power, then there must some compartment or universe that he has all power over.
No doubt you can find Mormons who would agree with your interpretation of D&C 132. However, it is not the only possible interpretation. I personally do not believe it.
The point is, what is the official doctrine?
I will admit that I cannot find anything about virtual ownership of women by the husbands or eternal pregnancy in the BoM or the D&C, only in the JoD, which seems to have fluctuating levels of authority depending upon the mood of the day.
You are unlikely to find either doctrine in the LDS scriptures. You might find something in the Journal of Discourses, but that has nev er been considered scripture by the Latter-day Saints.
What is the JoD, then? What is its purpose?
Which church? Christianity encompasses many different churches and denominations, which often disagree with each other on what constitutes heresy and orthodoxy.
If your particular church or denomination considers my beliefs heretical . . . well, I can live with that.
Still, I would like to know which branches of Christianity believe that Christ is disembodied. Perhaps someone will enlighten me.
The point is, what is the official doctrine?
I am not aware that the LDS Church has ever declared an official doctrine on such things as multiple universes or daily life in the celestial kingdom. In the absence of an official declaration (or direct revelation), we are free to draw our own conclusions.
There is no harm in that, so long as our speculations do not distract us from the truly important matters, such as faith, hope, and charity. I trust that everything will be revealed to those who endure faithfully to the end.
13 ¶ Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.14 For God shall bring every awork into judgment, with every secret thing, whether it be good, or whether it be evil. (Ecclesiastes 12:13-14)
