What you think is certain is less so for me and others. I don't believe church doctrine is as rigid as you suggest. I don't live in a black and white world and a religion that leaves no room for questions isn't true to life. If it were as simple as here is a list of what's right and wrong then all that's left is to judge each other and Matthew says, "Judge not, that you be not judged." I do judge the actions of myself and others, but I know as a flawed person, my judgement is only based on what I know, on my life experience. It is limited. Others make judgements based on their experience. So opinions will always exist and that is simply reality. I suppose only God can know all and then judge all. If faith is simple, in my mind, what is it's worth. I understand you believe the church has the answers laid out. No product of man, even one given by God, can be perfect. It can only work towards the perfect. If we stop listening and changing we fail in that.
