Hyper-Calvinism is a branch of Protestant theology that places strong emphasis on supralapsarianism, or salvation from eternity, where the atonement of Christ was and is difficult for the non-elect to understand, where man has little to do with his salvation, there being nothing man can do to resist being saved, wherein evangelism was given lower emphasis as compared to traditional Calvinism, and where assurance of salvation was felt within a person, identified by introspection.
