Where I do slightly disagree with him through is in this:
"Your entire religion is founded on an obsession with “sin”, with punishment and with atonement."
I object because I am not at all sure we are obsessed with sin, I think it would be more accurate to say we are obsessed with grace. I admit I think sin is serious and shouldn't be ignored. I admit I think God is going to punish the world on the last day, and yes I do think atonement is central to a correct understanding of the cross... but I am obsessed with grace. Grace is something so unexpected and so un-religious that it blows my mind. Religion says "be good and God will love you" grace says "God in Christ loves us more than we can know and repentance and faith not good deeds are the key to getting hold of that love."
