== Concupiscence == 

 I'm sorry, but citing a Roman Catholic encyclopedia that might allege that some Protestants thought concupiscence was the Original Sin doesn't cut the mustard.  If any Protestant or anyone else ever said such a thing, you should be able to cite exactly who it was.   AFAIK No Church has ever held such a doctrine, no Church Father has, no Christian writer has, but yet you are pushing it in the article as a "uniquely Christian doctrine" which is hardly the case.  That will have to be reworded, because it is simply a falsehood to call that a "uniquely Christian doctrine" when no Christians have ever even said any such thing.
