I would even go further, God does not approve of anything anyone does.
All of us have become like one who is unclean,
and all our righteous acts are like filthy rags;
we all shrivel up like a leaf,
and like the wind our sins sweep us away.
Is. 64:6
I think we should all be very careful how we judge others, especially in things that are not explicitly prohibited by the 10 Commandments. Nothing in the 10 commandments speaks to the topic of homosexuality. This does not mean that it is not wrong, but it does mean we need to be extremely careful deciding whether it is or not.
The only clear thing the 10 commandments says about sexuality is that we should not commit adultery. In other words, all sexual relations should be confined to a single partner to whom we are committed in a marriage relationship. Since Christian gays advocate the same, we need to be very cautious about condemning them, and even then we probably need to keep it to ourselves, and leave it to God to convince gays of their wrongdoing, if it is wrongdoing.
There are many things the OT says are wrong, outside the 10 commandments, including homosexuality, but we need to be extremely wary of clinging to such prohibitions uncritically. There are also OT laws that prohibit menstruating women from having contact with others lest they cause them to become unclean, planting more than one kind of seed in a field, and wearing clothing woven of more than one kind of cloth. Interestingly, there is no prohibition against polygamy, which would seem to be against the 7th Commandment.
Obviously, we have made choices regarding these additional OT laws as to which should be followed and which are no longer relevant. Have we made the right choice in all cases? Some would argue that the SDA adherence to the Levitical laws concerning clean and unclean foods was a poor choice. Most Christians seemed convinced we have made the right choice to consider homosexuality wrong, but even in this determination we need to stop a moment and consider whether the so-called “ick” factor may be part of what has convinced us homosexuality is wrong. I would suggest we not be so quick to condemn something just because Christians have long condemned it, or that we do so just because it automatically leaps out at us as “unnatural.”
I think there is a reason Jesus said,
"“Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? 42 How can you say to your brother, ‘Brother, let me take the speck out of your eye,’ when you yourself fail to see the plank in your own eye? You hypocrite, first take the plank out of your eye, and then you will see clearly to remove the speck from your brother’s eye.” Luke 6: 41-42
I think Jesus is saying we all have a speck in our eye, and I dare say it is a lot more difficult to remove than many of us seem to believe. Thus, our set point should be, “judge not,” period. In the case of homosexuality, I think we must, if we are to follow Christ’s intent, just love and accept. As long as homosexuals are willing to adhere to the 7th Commandment (and remember, we heterosexuals are bound to do the same), I think we MUST accept them. Have personal reservations if you like, but keep them to yourself. Many gays have enough doubts about whether they are right before God or not. They do not need the rest of us to try and set them straight.
To love as Jesus loved, is to love in word and action.
