The “great and abominable church” or “church of the devil” are expressions “used to identify all churches or organizations of whatever name or nature-whether political, philosophical, educational, economic, social, fraternal, civic, or religious which or designed to take men on a course that leads away from God and his laws and thus from salvation in the kingdom of God.” Further: “Any church or organization of any kind whatever which satisfies the innate religious longings of man and keeps him from coming to the saving truths of Christ and his gospel is therefore not of God.” (Mormon Doctrine, pp. 137-38.)
