I keep hearing that Christianity was a hindrance on the progress of humanity and caused the dark ages, is this true?
Here are some previous threads about the topic while you wait for new discussion.
How did the catholic church influence sciences during Middle age and Renaissance?
How truly anti-science has Christianity been historically?
How long have the followers of the Christian church been at odds with the science of their time?
I think further details are required here why do you think Christianity "was a hindrance on the progress of humanity"? What have they done, and to whom? Why did they do it?
