When I say we are all filthy sinners, I mean everyone, everyone is guilty and in that sence equal (sinners). What I did not say which I took for granted, is that your relationship with God is personal. A priest are able to tell you a lot of useful stuff about the bible and help you understand the paradoxes involving when you believe in God, but he is in no sence above you when it comes to whom is closer to God, not even the Pope is closer to God (surely some will disagree)
I think you may have misunderstood me.
My view is that this idea that all are automatically guilty is a ploy by the priests etc to make themselves necessary to you. If you are in the grip of this morbid self-hatred that they promote, you are more likely to come to their churches, mosques, temples, synagogues etc, donate your money, and generally put yourself in their power.
