I'd like to carefully read the proclamation on the family one paragraph at a time. My aim is not some authoritative interpretation but an attempt to examine my current thoughts about it.
1. 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.
This seems fairly obvious. This is a main point of church doctrine that refutes some ideas in many Christian traditions that marriage is lesser than celibacy. Families are more important.
2.
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.
This one is interesting. It's about gender identity. Gender extends to the spirit world. We know that this world is imperfect and flawed. There are definitely cases of physiological gender ambiguity, and that means that spiritual gender does not always translate perfectly to birth gender. So it seems to me that it's possible that there could be mismatches between birth gender and physical gender. Maybe this could be one cause of gender dysphoria.
3.
In the premortal realm, spirit sons and
daughters knew and worshipped God as their Eternal Father and accepted
His plan by which His children could obtain a physical body and gain
earthly experience to progress toward perfection and ultimately realize
their divine destiny as heirs of eternal life. The divine plan of
happiness enables family relationships to be perpetuated beyond the
grave. Sacred ordinances and covenants available in holy temples make it
possible for individuals to return to the presence of God and for
families to be united eternally.
This is pretty straightforward explanation of doctrine. It's unfortunate that many people have been denied the blessings of temple ordinances for a variety of reasons. Life's unfair that way. But if life were always fair, we wouldn't have to learn patience and longsuffering, and thus wouldn't be able to become like our Father in Heaven. And in the end, everyone will have ample opportunities, even if they are denied in the short term.
4.
The first commandment that God gave to
Adam and Eve pertained to their potential for parenthood as husband and
wife. We declare that God’s commandment for His children to multiply and
replenish the earth remains in force. We further declare that God has
commanded that the sacred powers of procreation are to be employed only
between man and woman, lawfully wedded as husband and wife.
This is the first paragraph that deals directly with the Law of Chastity. I noticed that it is worded to make sure plural marriage is not disallowed. There is ample evidence in the scriptures that chastity is extremely important to Christ, and those that feel the church should "stay out of the bedroom" haven't carefully studied Christ's teachings. However, the "only between man and woman" part is modern doctrine, or at least newly explained policy. The references to homosexuality in the Bible are all in places where cultural context makes their modern applicability questionable. And there are no references to homosexuality at all in the other standard works. Either homosexuality is a new problem that didn't exist back then or the Lord didn't feel it was important enough to comment on it in the past, which is possible. It could be a misinterpretation, or possibly it's just a doctrine for today. The word of wisdom is such a doctrine, as there is nothing inherently immoral about drinking alcohol. Christ himself drank wine. The word of wisdom is a commandment for our day, given "In consequence of evils and designs which do and will exist in the hearts of conspiring men in the last days." In all honesty, the commandment against homosexuality feels more like the ban on those of African heritage from holding the Priesthood than an eternal doctrine. Maybe it could be lifted. I don't know. Even if it is lifted, the Law of Chastity would still be in force and proscribe sex outside of marriage.
5.
We declare the means by which mortal life
is created to be divinely appointed. We affirm the sanctity of life and
of its importance in God’s eternal plan.
This is an important distinction of doctrine, because it flies in the face of much of traditional Christianity where sexual intercourse is vilified and marriage is a punishment for those who don't practice celibacy. The phrase "born in sin" is usually a reference to this tradition.
6.
Husband and wife have a solemn responsibility to love and care for each other and for their children. “Children are an heritage of the Lord” (Psalm 127:3).
Parents have a sacred duty to rear their children in love and
righteousness, to provide for their physical and spiritual needs, and to
teach them to love and serve one another, observe the commandments of
God, and be law-abiding citizens wherever they live. Husbands and
wives—mothers and fathers—will be held accountable before God for the
discharge of these obligations.
If parents bring children into the world, they have an obligation to provide for them, not just physically but also emotionally, socially, intellectually, and spiritually. The neglect of these obligations is morally reprehensible. Parents of LGBTQ+ children are not excepted from this duty.
7.
The family is ordained of God. Marriage
between man and woman is essential to His eternal plan. Children are
entitled to birth within the bonds of matrimony, and to be reared by a
father and a mother who honor marital vows with complete fidelity.
Happiness in family life is most likely to be achieved when founded upon
the teachings of the Lord Jesus Christ. Successful marriages and
families are established and maintained on principles of faith, prayer,
repentance, forgiveness, respect, love, compassion, work, and wholesome
recreational activities. By divine design, fathers are to preside over
their families in love and righteousness and are responsible to provide
the necessities of life and protection for their families. Mothers are
primarily responsible for the nurture of their children. In these sacred
responsibilities, fathers and mothers are obligated to help one another
as equal partners. Disability, death, or other circumstances may
necessitate individual adaptation. Extended families should lend support
when needed.
I mean, if children are important and chastity is important, marriages between men and women are rather essential. However, there are many couples who are incapable of having children. Their marriages shouldn't be relegated to side-note status. Ideally, children will be born to parents who are faithful to each other and care for their needs. But in this fallen world, there are broken marriages, orphans, neglected children, etc. Single parents, adoptive parents, and other alternate care-giving situations deserve strong support from members of the church if the well-being of children is truly valued.
8.
We warn that individuals who violate
covenants of chastity, who abuse spouse or offspring, or who fail to
fulfill family responsibilities will one day stand accountable before
God. Further, we warn that the disintegration of the family will bring
upon individuals, communities, and nations the calamities foretold by
ancient and modern prophets.
Again, parents of LGBTQ+ children who fail in their obligation to care for those children will stand accountable before God. The breakdown of the family is of definite concern to members of the church, but I think it's easy to be distracted by the "gay marriage movement." That movement does little to contribute to the breakdown of the family as compared to things like children being born outside of marriage, spousal abuse, spousal infidelity, and other such problems. Yet the first thing I often hear about in Elder's Quorum when the breakdown of the family is mentioned is gay marriage.
9.
We call upon responsible citizens and
officers of government everywhere to promote those measures designed to
maintain and strengthen the family as the fundamental unit of society.
I am wholly behind strengthening families, as they are the fundamental unit of society.
In general, the family proclamation is very reasonable and a succinct statement on the value placed on families by the church. I question the focus put on fighting gay marriage, but I see where it is coming from. In many eyes, couples living together having children outside of marriage is remediable simply by encouraging them to get married, so it's seen as not as bad as gay marriage; but I think that's misguided because of the propensity for children to be harmed in the former rather than the latter.
Members who use the proclamation as their reason for opposing gay marriage need to read the whole document and take a look at where their efforts would be best used. Activism against "abuse [of] spouse or offspring" gets short shrift compared to the efforts of members decrying homosexuality, and that's too bad.
