This is a Daniel Quinn argument, but i really like it.

if the teachings of Christ and those documented in the Bible are meant to be taken as natural law, then why do they have to be repeated so many times to Christians? Why do Christians have to constantly be reminded WHAT and WHY they have faith in?
Its like the law of gravity: you are only told it once in your life and thats it, thats all you have to know and understand...but christianity, you may be taught or told the same thing over and over. I feel that the repition needed to implicate the relivance of this religion denotes the flaw in the very far-fetched teachings.

Also, the concept of "salvation" seems to be the over-riding theme of christianity....why? shouldnt an individual be more concerned about the just and right way they live instead of the consequences of the way they live?
Why were the books at the end, ala Revelations, tacked on so late after the completition of the bible? was it just THAT hard to take Christianity without a negative paroble?

Why do Christians seem to be the ONLY faith who have little to no respect for other faiths? I have failed to see an Evangelistical jew or hindu. The Islam doods on the corner selling fruit and their papers leave you alone as soon as you say your not interested, but despite being told time and time again Christians keep coming back and treating those "unconverted" like fools and idiots...why? it is akin to the mentallity that colonial whites had toward native peoples of america and those inslaved from africa, that they were just too stupid to grasp the "correct" way to live so they should be forced to...
why do christians cry for an atrocity when christians living in Islamic states are denied the ability to worship but never say a thing when they go to countries like Tibet, Pakistan, India, etc...and destroy the age-old societal religions with demeening "missionary" revivals?

If it is a truthfull and non-mythological religion, then why does it have to be morphed and tailored to fit so many individuals comfort zones, from the Unitarians to the southern Baptists to the Episcopals to the Methodists to the catholics to the protestants to the quakers to the "sunday morning screamers"?
Why does god need money?
Why does donating money or giving money to a CHURCH make you a better christian? Is the physicall "church" more important than an individuals own spirituality?

anyway...
