text: While Christianity did not actively prescribe slavery, as Islam does, it did not forbid it, either. It accepted the existing social order ("render unto Caesar what is Caesar's"), it did not set off to revolutionize it. So there was nothing specific that prohibited it, as a traditional social institution that existed in societies all over the world, it was accepted. For centuries it did not occur to anyone to rebel against it.
  
  But while the New Testament says nothing about slavery as an institution, it does say that in the eyes of God there is no slave or free man, male or female, etc., all are equal, and slaves were part of early Christian converts.
  
  Over time, this belief, along with tenets to "do unto others as you would want them to do unto you", and the growing importance of the value of "freedom" in western society, led to a social movement spearheaded by devout Christians, based on Christian principles, to abolish it. It was successful, and now we consider slavery abhorrent.
