McConkie (1915–85) said: “The titles church of the devil and great and abominable church are used to identify all … organizations of whatever name or nature—whether political, philosophical, educational, economic, social, fraternal, civic, or religious—which are designed to take men on a course that leads away from God and his laws and thus from salvation in the kingdom of God” (Mormon Doctrine, 2nd ed. [1966], 137–38).
