Christianity kept a hell of alot of the roman tradition alive... kept writing alive (in europe) throughout the dark ages... and a bazillion of the first people to get us our of the dark ages were christian.
The Byzantine empire (christian), the cathloics and the islamic empires kept eachother in check for about 700 years... if christiananity never existed... and islam kept on its path it was on before it smacked into christians... well... you would prolly be praying to mecca 5 times a day. Females couldnt go to school, and the only good technology is that which helps you kill the people who think that you should prey at 1:30 instead of 2:00. (or some other silly peety interdocturnal silly thing)
while the chinese were advanced... India was advanced... the americas were "advanced" in their own way (lovely calender, awesome architecture)... there was a reason there was a time where the sun never set in the british empire.
Ima not done with my post here... but Real Life calls for an hour or 2.
i just wrote a really ...rabid response. but decided you didnt need to be reamed.
christianity did the exact opposite of keeping the roman tradition alive. it erased it leaving only roman numerals, some history, and the knowledge of steel.
if christianity hadn't existed, millions of my people wouldnt have been murdered for papal greed and royal treachery. much less the millions of people who would have been saved by roman, jewish, or moorish medicine and hygeine during the bubonic plague.
it delayed the acceptance of arabic math and letters (what we use todays) invented a being called satan to scare the ignorant into being a afraid of them, bullied kings into wars of conquest and persecution. destroyed great works of art and achitecture to build cathedrals and palaces dripping with gold for men who had sworn to lives of poverty... thus depriving anyone else the chance to move up. it limited the education or people to the church. even aristocrats were illiterate... thats why stained glass windows ere created... to tell the story to people who couldnt read.
during the dark ages of europe (pre reformation... so only the catholic church) it was islam's golden age... which ended, surprisingly, when the christians invaded.
essentially what i am saying here is that without christianity, the roman empire would have survived, or the caliphate would have continued to make progress in the areas of poetry, science, art, mathematics and law, or the jews wouldn't be only .2% of the world population, with all their knowledge wasted on catholic kings. or the byzantine empire would have continued to create newer, fairer laws, that would only be forgotten until after secular governments were emplaced. the aztecs could have continued to advance and the native americans wouldnt have been slaughtered.
i can lay most of the evil done in the last thousand years to the arrogance and ignorance of the perverted christian relgion. and then i can turn around and say that most of the good done in the last 200 years was done by protestants (who rejected the catholic church's teachings).
ok, this still turned into a rant. im sorry.
jesus equals god, but the medieval christians equal the worst thing to happen to mankind... ever.
