[1] Hope for man and the world. When I was a Christian, I thought we were all goners. It was always the end times, and we were all praying for Jesus to come again and destroy the earth. But now, I know that it is possible that man can go on until he evolves into something better, and then again.
[2] Freedom from bondage caused by the fear of damnation. Freedom from fear of hell. Freedom from fear of Satan. Freedom from fear of demons and devils. Freedom from fear of my own thoughts. Freedom from the belief that I may be forced to remain conscious for much more than trillions of years no matter how boring or unpleasant existence becomes.
[3] Freedom from the illusion of being constantly watched by an angry, judgmental, authoritarian, smiting, prudish overlord.
[4] When a cute little doe-eyed girl dies of leukemia sometime later today (and one will somewhere), you'll have the comfort of knowing that it was just rotten luck, and not something caused by or allowed to happen by any ghost.
[5] Respect for mankind, life, earth and the universe. Christianity teaches that animals are soulless meat bags to be exploited as man sees fit, and man a constitutionally diseased creature. Then it teaches that the whole material world including earth is made of a base substance - matter - which is only transitory. Christianity demeans mankind enough to make the phrase "the flesh" derogatory, and the material world enough to make the word "worldly" an insult.
[6] Freedom from an intellectual system that despises science and erudition, and robs the victim of the sense of the sense of mystery, grandeur, awe and connection that a scientific education entails. "We are stardust. We are golden. We are billion year old carbon."
[7] Freedom from an ethic that defines love in terms of torture and crucifixion, or a pardon from eternal torment by an infinitely evil devil created by an allegedly loving god. The moral structure is deformed: Faith, obedience, worship and piety are not virtues. Autonomy is a virtue, not submission. Becoming educated in the liberal arts is a virtue, not learning the Bible. Courage is a virtue, not meekness, Christianity has no use for most of those.
[8] Respect for mankind. Christianity teaches that man is unworthy, inherently flawed, retched, unworthy, worthy of punishment from birth, lucky to be tolerated by the god, and that his societies are to be shunned and despised. Christianity demeans man and his societies enough to make the phrases "the flesh" and "the world" insults.
[9] As suggested above, relief from thousands of hours spent in churches, praying, and reading the bible. I have learned much more reading unknown numbers of better books than that one. I had a nice Sunday morning today walking into the village with my wife and a third friend to enjoy breakfast in the plaza and pick up some DVDs while others were in the chapel doing what people in churches do on Sunday mornings. What's that worth?
