Assumptions and dogmas I can not believe:

1.) That the bible, or any sacred text, is the inerrent "word of God", some special production overseen by the almighty, without error, or even divinely inspired. That during it's synthesis men were infallible conduits, and didn't interject their own false beliefs, prejudices and assumptions into it. That it has been handed down, translated and interpreted perfectly, without inherent limitations of words and language fundamentally affecting it's meaning. That men were, for some reason, closer to God in previous ages, and that God communicated with people back then in a way he/she doesn't today. The underlying assumption of every religion relying on "revealed truth" or sacred texts is a belief "a priori" in the special, divinely inspired status of the sacred texts, when there is no reason to believe that sacred texts are anything but the creation of men.

2.)That there were two "original people" in some utopian garden, and that these two people are the literal ancestors of all humans. Many Christians today, (though not all) have accepted that the Genesis story of a literal creation of the universe in six days, about six thousand years ago, is impossible to reconcile with what we know from science, and understand it as a metaphor. For some reason, that Adam and Eve might be a metaphor also seems harder to accept.

3.)That there was a "fall", that the two "original people" made a mistake that accounts for all the problems and suffering of humankind. That God would create a situation whereby a "fall" could happen. That there is such a thing as "original sin". That people have some inherent affinity for evil or tendency to do wrong, some intrinsic status from which they need to be "saved". The whole concept of a fall is rooted in mythology, nothing more than ancient man's attempt to reconcile a belief in the almighty with an imperfect world full of suffering and hardship. The ideas of "original sin" and man's inherent unworthiness is a guilt trip, a tool to manipulate people and have power over them.

4.) That there is an eternal, everlasting hell waiting for those who don't get it right in their brief existences here on Earth. That there is a "devil", a satanic demon who can thwart the will of God and who plots to lead people astray with temptations and trickery. Frankly, I think that a concept of eternal damnation, suffering, torment, pain and separation is the product of those lacking in love and understanding, and belief in "the devil" is the result of somewhat twisted, overactive, and perverse imaginations.

5.) That Jesus was God, born of a virgin, and preexisted the universe. That Jesus had miraculous powers.

6.) That upon death Jesus physically ascended up into "heaven". (I thought heaven was a spiritual realm?) That this fate portends all the believers who will be literally physically reconstituted in the end times, to rise up into the clouds physically to meet the lord. Surely this belief is a reaction to fear of mortal death. Surely, as long as we are imagining fantasies of immortality, we can come up with something more appealing than literal physical resurrection. Have people really thought about this most basic creed of the Christian doctrine???

7.)That there will be an "end of the world", that the physical body of Jesus will come down from the atmosphere (how this is supposed to happen literally, simultaneously to all believers all over the world, escapes me, although I am sure there is SOME answer for it). That all the believers will be literally whisked up into space, while the poor wretches left behind will undergo some sort of hell on Earth under the cloven hoofed one. That there will be a final struggle between good and evil, and that the tortured hallucinations recounted in Revelations are anything but just that. To read the bumper stickers of the believers confident in their special status, fully expecting to be raptured out of their seats as they drive down the highway, does not inspire confidence in me as to the sanity or rationality of a good portion of the human population.

Other than that, Christianity is fine - you know, the stuff about love your neighbor, forgive your enemies, and do unto others - all that (and I'm not even sure it can take credit for those ideas, either) .
