In the 1928 Book of Common Prayer, the confession of sins says "We acknowledge and bewail our manifold sins and wickedness, Which we, from time to time, most grievously have committed, By thought, word, and deed, Against thy Divine Majesty, Provoking most justly thy wrath and indignation against us." Harsh words. I've heard it complained that they make it sound like we commit murder every week. And yes, they do, because we do.
My roommate Josh recently wrote a post over on his blog about hypocrisy. In that post, he talks about a distinction between the cynic and the hypocrite. The cynic is one who sees the flaws of the system he is a part of, withdraws from them, and claims for himself superiority. The hypocrite, on the other hand, is one who sees the flaws of his system, bewails them, strives to get out of them, all the time realizing that he is a part of them inescapably, and that because of this he will always be part of the system.
We live in a world of horrendous injustice, our entire economic system is tied in with the exploitation of the weak, the destruction of animals, the rape of our world. What is more, this side of the Resurrection, we live as fallen bodies oftentimes overwhelmed with desire that leads us to sin. We cannot withdraw, not until Christ returns and we are transformed. We must fight it, but we must, always, realize that we cannot escape it. We sin each day, even in ways we don't realize. I sin when I look at another person and put her into a box (vain Hollywood girl), I sin when I eat chocolate harvested by slaves, I sin when I sit in a car whose fumes are destroying the planet. There are even situations, as I have talked about before, where any action I can possibly take is wrong (kill the one, or let the many die?)
This isn't to say that I am some wicked or worthless person. I have been made in the image of God, and remade in the Resurrection of Christ. I have been sanctified and my sins are no longer held against me. I am beloved of God. When I bewail my wickedness, what I bewail is that I am not yet whole. I have been made clean, the seeds of the Resurrection have been planted in me, but they have not yet blossomed.
This is why we cannot judge. But for the irresistible Grace of God, what would we be?
