Being a Christian is believing in Christ just as being a Buddhist is believing in Buddha. I strong belief that my personal relationship with Christ/God enables me to make decisions about what I choose to believe. No one can tell me what Christ wants me to do. Christ/God speaks to me thru the Bible and personal experiences as well as what others have written.
I also strongly believe that churches do not have all the answers. They are organized by men and also have access to God but what they believe is also based on their interpretations of the Bible, personal experiences and what others have written.
I believe the Bible is inspired by God but so are many other writings and ideas. The Bible was written in a different century during different social expectations. What is important about the Bible are the principals it teaches.
During the time the time the Bible was written gay relationships were not only not accepted but were also scorned. I believe that teaching was against the teaching that God is love. You can find verses that teach about God's love and when you do I believe you'll find that God accepts gay relationships.
I know that many, many people believe that what I believe is heresy. I strongly believe that what I believe and do is between me and God. I am not responsible for my beliefs to any mortal on this earth. God will judge each of us. Christ specifically says not to judge.
