vibrant, Christian, and coherent civilization
Vibrant despite christianity, which spent an inordinate amount of effort trying to kill off or coopt any part of a culture which did not align with the interests of the clergy or the asinine prescriptions of antique cultists.
As for being coherent, there are no commonalities between the cultures from one side of Europe to the other. Not even christianity considering how much they differ between the catholic, protestant and orthodox variants, along with the centuries of war fought over religious differences in supposedly the same religion.
Christianity, along with the other monotheisms, is a blight on humanity, because it claims to be true, despite all the contradictions, the nonsense and the corruption it breeds. It does not accept the most fundamental of freedom, ie freedom of thought.
