We, the First Presidency and the Council of the Twelve Apostles of The Church of Jesus Christ of Latter-day Saints, solemnly proclaim that marriage between a man and a woman is ordained of God and that the family is central to the Creator's plan for the eternal destiny of His children.
All human beings—male and female—are created in the image of God. Each is a beloved spirit son or daughter of heavenly parents, and, as such, each has a divine nature and destiny. Gender is an essential characteristic of individual premortal, mortal, and eternal identity and purpose.
Remembering that this whole statement is considered a "guide" and not a "revelation" by modern-day prophets, I will still approach this document as if it held weight as for reasons people believe homosexuality is bad.
In the first paragraph, it says nothing about homosexuality. It does say that marriage between man and woman is ordained of God, but it doesn't say that marriage between man and man or woman and woman is evil. It also says that the family is ordained of God, but does not specify what that family looks like. So I would have to say I agree full heartedly with those two statements.
Having said that, consider this: Say a woman was deceiving her husband during their time dating. Lets say that she led him to believe that she was a committed member of the church and believer in Christ. In fact, however, she never intended to stay in the church or raise a family in it. He, on the other hand, believed that she was on the same page and, like himself, was fully committed to the gospel. They get married in the Temple. A few short weeks later, the wife informs her husband she is leaving the church and doesn't want her family to be raised in it. They divorce. Now this was a man and a woman, married in the temple. Was it ordained of God? This is a true story. It is the story of one of my mission companions.
Another short story: A child grows up in an abusive home. His parents are a danger to his life. In order to survive, he literally has to run away. But his mother and father were his biological parents. Do you think that kid will smile at the news that he can be with his family forever?? No. Not a chance. That would be his hell. Was this family ordained of God?
My point here is that just because it states that marriage between man and woman is ordained of God and family is ordained of God doesn't mean that EVERY marriage and EVERY family is ordained by him. With the same reasoning, I would argue that just because it says that these two institutions are ordained of God, it doesn't mean that others are not.
Okay, now the second paragraph. First of all, I think that the wording is interesting. All humans- BOTH MALE AND FEMALE- are created in the image of God. Does anyone else find that interesting? How can both be in the image of God? I mean, we obviously have different parts right? Hmm... just something to think about, but I have no argument with it. Nor do i have a problem with the idea that God loves all of us.
One argument that is used against homosexuals that bothers me A LOT is a phrase within this paragraph. That phrase is "Gender is an essential characteristic of individual premortal, mortal, and eternal identity and purpose." Okay. That is fine. Being gay doesn't mean that I want to be a girl. I recognize and accept that I am a man and that it is part of my identity. I am in no way trying to reject that. So I have no argument with this either (when it comes to myself).
But now lets consider some people that don't fit inside this box we've so easily divided in half, females on one side, males on the other. What about those individuals with nondescript genitalia? What about those with both? How do you determine their gender? Does it need to be determined? Can you imagine being one of those individuals and reading this statement? Where do they fit in? What do you tell these people? In this document we are saying that gender is an essential characteristic, yet there are many who cannot be classified into male or female.
So my point is, first this idea of gender being an essential characteristic isn't any reason to justify the idea that homosexuality is inherently wrong. Second, obviously this document isn't all-inclusive and leaves out some individuals who God loves just as much as the next person.
