So denuseri, are you claiming that the Catholic missionaries did not orchestrate the destruction of "pagan" temples and manuscripts (Mayan Codices, in particular)?
But it started long before that! From http://en.wikipedia.org/wiki/List_of...ning_incidents (yeah, not the best source, but at least it's not atheist!)

"The books of Arius and his followers, after the first Council of Nicaea (325), were burned for heresy. Arius was exiled and presumably assassinated following this, and Arian books continued to be regularly burned into the 330s."

"In 364, the Christian Emperor Jovian ordered the entire Library of Antioch to be burnt.[18] It had been heavily stocked by the aid of his non-Christian predecessor, Emperor Julian."

"Elaine Pagels claims that in 367, Athanasius ordered monks in the Coptic Orthodox Church of Alexandria in his role as bishop of Alexandria to destroy all "unacceptable writings" in Egypt, the list of writings to be saved constituting the New Testament."

And let's not leave Islam out of this! "Uthman ibn 'Affan, the third Caliph of Islam after Muhammad, who is credited with overseeing the collection of the verses of the Qur'an, ordered the destruction of any other remaining text containing verses of the Quran after the Quran has been fully collected, circa 650. This was done to ensure that the collected and authenticated Quranic copy that Uthman collected became the primary source for others to follow, thereby ensuring that Uthman's version of the Quran remained authentic."

The destruction of "heretical" or "treasonous" writings has long been a staple of autocratic, and theocratic, rulers. The RCC was no exception!

As for the Renaissance, there can be no argument that the Church is responsible for vast quantities of art and architecture. Of course, there were few outside of the Church and the nobility who could afford to sponsor such art. And naturally, as the buyer, the Church had the final say on the FORM of such art. Anything which clashed with Church teachings would be unlikely to be acceptable. And the artist who created such works would be lucky to simply be banished.

But the Church also conspired to keep the common people from reading the Bible. Few outside of the nobility and the Church could read their own language, much less Latin. Yet the Church condemned to death many people who translated the Bible into languages OTHER than Latin. This is not the act of an organization which wanted to revive learning, but of one which wanted to control it. Look up John Wycliffe and William Tyndale for verification. I don't want to point you to any atheist sites.
