I'm saying that the Christian church is full of members, all sincere in their efforts to understand and embrace a value structure based on their sense of God (which I refer to the mythology of God, not because it's false, but because it will always be unprovable).

There is great variety of belief in the Christian church.    I don't have a litmus test for who qualifies as a Christian and who doesn't, it's not my place to make that judgement.   I hope my faith shapes at least some of my social values, but I don't need a flag, or a cross, to justify my opinion.  To give credit to my readers, I try to let them know my motivation.

As you've noticed, I do have an opinion. I will argue for my beliefs.   I don't claim perfect knowledge.  I don't claim to speak/write only the truth.   I am an imperfect human being, full of mistakes, that believes grace and forgiveness are qualities of both god and the human species.  

If not, I'm screwed!  :-)
