The most common argument I hear against homosexuality is that the Bible forbids it. It is true that there are Bible verses forbidding homosexual acts. However, having read almost the entire Bible, I still don't feel like homosexuality is wrong. I believe that the Bible is the word of God, and I try to live my life by the principles I find in it, the most important one being to love God and other people. The old testament forbids many things that Christians today do not follow, so the old law most Christians don't enforce anyway. There is a new testament verse or two condemning homosexual acts, but the new testament also says women should say silent in church; however, I know most Christians also support women pastors, although there is still debate going on about that. The new and old testament were also used to support slavery, which was clearly wrong, and no one would say that slavery is a good thing today. I don't think the Bible was written so we could use it to condemn groups of people. I feel that the issue with homosexuality is very similar to these issues. It doesn't mean we should ignore the Bible or that what it says doesn't matter, I just think it's important to read it with love and justice in mind.
The Bible was also and still is used to condemn scientific principles that are discovered about our world and universe that we live in. As someone who loves both theology and science, I don't think that has to be the case at all. The Bible is not a science textbook. People used to think it was heresy to say the earth revolved around the sun, because there are Bible verses saying the earth doesn't move. However, I think most people now accept that the earth moves around the sun and believe in God without experiencing conflicting feelings.
I do know many Christians who say they love homosexual people they just disagree with the choices they're making. I also hear people say homosexuality isn't natural. There are increasing amounts of scientific evidence that being homosexual or bisexual isn't a choice. That makes sense to me, because I don't recall ever making a choice to be attracted to men. I just am naturally attracted to them. I have talked to homosexual Christians who have struggled so much with trying to not be attracted to the "wrong" sex, but they eventually come to the realization that the gender they are attracted to isn't a choice. So I have a hard time believing that something that isn't a choice would be a sin.
This leads me into just a short tie in with depression. I feel empathy for homosexual Christians, because I feel like as a Christian with a mental illness I have been wrongfully condemned for my "sin" and bad choices I make to be depressed or anxious. There are also Bible verses used against my illness where people say the Bible says to not be depressed or anxious, and tell me my feelings are sinful and my fault. I grew up thinking that, and it's been very difficult for me to pull away from that belief, as people still tell me things like this frequently. After having depression and anxiety for 7 years though, meeting many other people with depression, and seeing scientific research that has been done, I've concluded that me and many others have a disease which was not our fault or choice and therefore isn't a sin. I'm not at all trying to say homosexuality is like an illness, just that I feel sad for those who are told being homosexual, or having depression is sinful, because I feel like the Bible and Christianity are being used to hurt rather than help people.
One last thing I was going to say was just to request that if you disagree with anything I've said, that you would discuss it in a calm manner.
Peace.
