Every now and then one question which gets put to me is: “If God declared homosexuality to be OK would you say it’s OK?” It’s an interesting possibility but in order to me to say either ‘yes’ or ‘no, the question would be ‘What difference would it make to the world if God did declare same-sex sexual relationships to be OK?’ The answer to the second question, I find, makes the answer to the first not as straightforward as it might seem. Here’s why:
1) From what is known in the Scripture, who is permitted to participate in marriage and sexual union? Genesis 2:24: “Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh” (And yes, Jesus upheld this in Matthew 19:5-6; He never endorsed homosexuality). Marriage is for one man and one woman; not more than two members of each gender (polygamy) and not opposite sex partnering. No unions with animals, relatives, adults and children, premarital sex, rape, extra-marital sex, etc.
2) So why only male and female? The woman God created was given to the man she married in order to be a helper suitable/comparable to him (Gen 2:20); indeed, none of the animals can help the man sufficiently (Gen. 2:20). Yet the woman is not merely a helper (the animals, at some level, can help the man) but she is part of the solution to his loneliness (“Yahweh God said, ‘It is not good that the man should be alone; I will make a helper fit for him’”, Gen. 2:8). (She is only a part of the solution to the man’s loneliness because only God is the ultimate solution to that.) God did not provide him with another man or any other living or inanimate thing. It was a woman: someone who is equal but also different to him. Both genders that reflect the image of God. There is to be sameness in the marriage (both are flesh made out of dust in God’s image) but there is diversity. The man is like God in some ways; and the woman is like Him in others.
3) Therefore, in same-sex relationships there is lacking a diversity in their structure. It is all-male or all-female. It rejects the opposite sex (which is somewhat ironic given how emphatic GBLTI communities are about how they represent social ‘diversity’). While same-sex couples would not see the opposite sex necessarily as negative, in the practise of their relationships they redact the opposite-sex. Their relationships have no need for the opposite sex. They biologically cannot rear children because they lack the diversity and the gifts that both sexes bring to a marriage to make a family properly function, yet even if they could have children in their family (like today) two fathers cannot possibly even come close to doing the job of a father and a mother (a male and a female together). They are innately unworkable, not because of any social or external imposition but because they lack the basic essentials to operate.
4) The implications for creation? In order for God to make a universe where homosexuality could work, He would have no need to create two opposite genders. Indeed, opposite genders would make absolutely no sense. Indeed, he would not have made Adam a man (in fact, a man is not known as a ‘man’ unless he has an opposite other, a ‘woman’, in contrast. Light is not ‘light’ unless there is darkness in contrast). In other words, for homosexuality to work the universe would need to be genderless. That would mean a lack of diversity. Species could not reproduce. Interestingly in the Genesis account there would have, before the woman was made, presumably both male and female in lower creation (the animal world). But in Genesis 2:20 and following, it enters the human world too. Right throughout the rest of Scripture, God and Jesus are referred to as a husbands and Israel/the Church as a brides (e.g. Ezekiel, Ephesians 5). The male-female images are even spiritual, representing diversity and unity.
So if people are seeking a universe that permits homosexuality it really is looking at a world that has a large, gaping hole where diversity is meant to be. But do they really want a world with no diversity? Scripture says that in Christ worldly categories of diversity mean nothing (Jew, gentile, male, female, slave, free, etc (Colossians 3:11)) and yet it is also upheld on the last day (in Revelation (7:9) and other places we are told that in the Kingdom of Heaven there will be people of all nations, tribes, and tongues). But homosexuality and other forms of sexual immorality will NOT be a part of that diversity (Rev. 21:8). There will be diversity, yes, but not in the sense of any and every lifestyle coming in. But the point is that for God to create a universe where He permits same-sex unions is to be in a place where fundamental parts of what it means to be human (male and female, complimentary and diverse) is actually eliminated rather than fostered.
