THIS IS FOR THE OP & MAY BE OF INTEREST TO CHRISTIANS BUT NOBODY IS OBLIGED TO READ OR COMMENT.
Op, the Old Testament was God-breathed and written by people who lived by certain guidelines, many cultural. Much of the OT was written in story form, conveying a truth, eg Adam and Eve, the Tree of Knowledge and Good and Evil. The idea behind that was to foster respect and awe for God, and a degree of obedience. However there are not many left who believe in a literal Adam and Eve, or that the world was created in six days (some do).
In the NT St Paul, for example, was very much a man of his time and his aim was that no Christian could be accused of any scandal; at that time, the society mores did consider many things to be beyond the pale, homosexual relationships was one. However none of the people then knew what we know now, their science was not developed for a start.
Human life has evolved and there have been many surprises/revelations along the way. Most people no longer think as they did in Biblical times, even fifty years ago. A homosexual is not someone who has chosen a wrong path, he or she was born that way. In this day and age they are able to form solid relationships, which most want, without fear of ostracisation or, worse, imprisonment.
Outrages have been committed against people in the name of religion, all or most religions, not just Christianity, which are quite shameful. A loving God, personified in His son, Jesus, did not want that but we have free will and must work things out for ourselves. That takes time and there are casualties along the way. Homosexuality and/or homosexual practice is just one example, divorce is another, having a child out wedlock yet another.
We are fairer now, we see integrity in everyone and are aware that we all fall short of perfection. In the Western world we are fortunate but there will always be people, and groups, who home in on issues that don't align with their own prejudices; they often influence others who are not by nature prejudiced.
Many Anglican and Catholic churches are inclusive. They accept gay people and couples, however, though the clergy may embrace this, the hierarchy still bans marriage in church. Marriage in church isn't everything even for a Christian, a legal marriage is quite valid, so is a civil partnership, also a less formal commitment between two people.
God sees each of us as a whole person, not just our sexuality.
Sorry this is a bit long. I shall say no more.
