'...the Bible's sober anthropology rejects the apparently commonsense assumption that only freely chosen acts care morally culpable. Quite the reverse: the very nature of sin is that it is not freely chosen. That is what it means to live "in the flesh" in a fallen creation. We are in bondage to sin but still held accountable to God's righteous judgment of our actions. In the light of this theological anthropology, it cannot be maintained that a homosexual orientation is morally neutral because it is involuntary.'
