“In relation to the kingdom of God, the devil always sets up his kingdom at the very same time in opposition to God” (Joseph Smith, in History of the Church, 6:364).
Elder Bruce R. McConkie (1915–85) of the Quorum of the Twelve Apostles defined the great and abominable church: “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).
One commentator explained that the great and abominable church consists of more than one entity:
“Actually, no single known historical church, denomination, or set of believers meets all the requirements for the great and abominable church: it must have formed among the Gentiles; it must have edited and controlled the distribution of the scriptures; it must have slain the Saints of God, including the Apostles and prophets; it must be in league with civil governments and use their police power to enforce its religious views; it must have dominion over all the earth; it must pursue great wealth and sexual immorality; and it must last until close to the end of the world. No single denomination or system of beliefs fits the entire description. Rather, the role of Babylon has been played by many different agencies, ideologies, and churches in many different times. …
“Can we, then, identify the historical agency that acted as the great and abominable church in earliest Christianity? Such an agent would have had its origins in the second half of the first century and would have done much of its work by the middle of the second century.
“This period might be called the blind spot in Christian history, for it is here that the fewest primary historical sources have been preserved. We have good sources for New Testament Christianity; then the lights go out, so to speak, and we hear the muffled sounds of a great struggle. When the lights come on again a hundred or so years later, we find that someone has rearranged all the furniture and Christianity has become something very different from what it was in the beginning” (Stephen E. Robinson, “Warring against the Saints of God,” Ensign, Jan. 1988, 38–39).
