Yes, the idea that a man or woman could know the mind of God, or what God would want any given person to do, and giving absolute statements concerning such things bothers me.
Why do people fall for it? We are social creatures, churches are social clubs. Having a faith or belief system is comforting, but only because it generally provides either the answers for you(without you having to think about anything), or it provides a self appointed mouth piece for the mind of God to answer the tough questions.
I have all kinds of faith in God, but my interpretations of scriptures do not fit into the mold of "Christian," and I do not go to church either; and for the same reason. I even hesitate to call myself a "Christian," for the stigma of the term. That does not mean, however, that my views of the Bible are not sane, reasonable, very well thought out; and capable of getting me burned at the stake in certain places in time.
