This false idea that the church caused the "Dark Ages" just has to be corrected AGAIN. The Dark Ages were caused by the simple reversion of Europe to its USUAL condition of darkness after the Roman Empire fell and its influence was no longer strong in Europe.
This seems to ignore the fact that at the same time the Spanish Caliphate was a bustling and tolerant civilization with the largest metropolitan areas in all of Europe such as Cordoba, with running water, with health care, with universities and a far higher standard of living, with Christian Monasteries and Nunneries.
That left the barely established European Church as the only civilizing influence, and that is how it functioned, more and more as it grew over the centuries. It was a force for order and morality among the warring tribes, and it preserved much of the works of civilization.
What? Barely established? The only civilizing influence? It was the Church that carried out many of the barbarities of the era. You yourself admit that it became a political power, but then you retreat into your "not real Christians" copout and defense. That is an interesting tactic but seems really selfserving. They were Christians, not very good Christians but Christians none the less. To connect the Dark Ages with Protestant Revolution (or Reformation depending on your POV) is just silly.
The Dark Ages extended from around 400CE to around 1000CE. The Protestant Revolution was a 16
th. Century event. Just as with the fall of the Soviet Union, communication led to the end of the Dark Ages. Travelers and in particular Monks and Nuns returning from Caliphate Spain brought back both the knowledge to be found there as well as tales of the wonderous cities and universities and running water and plumbing and the world of ideas and free thought and Jews and Muslims and Christians living together and debating as equals and teh markets and foods found under the rule of the Caliphs.
But that did not change the fact that the driving force of the Christian Church, throughout much of history was the destruction of the civilizations it found, as can be seen in this painting "The Truimph of Christianity."
