Stafford Carson says

we believe that planting our feet on any foundation other than the Bible is a dangerous and perilous place to stand.

And I agree with him. It is important for ‘orthodox’ Christians to understand that many gay Christians believe exactly the same thing. Our disagreement is not in the foundation of what we believe, it is that one group believes that the Bible teaches one thing, and another group believes that it teaches another. Neither side ignores parts of the Bible, or decided that they know better than God.
