“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; ... 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. …
(Stephen E. Robinson, “Warring against the Saints of God,” Ensign, Jan. 1988, 38–39).2
The great religious leaders of the world such as Muhammad, Confucius, and the Reformers, as well as philosophers including Socrates, Plato, and others, received a portion of God’s light. Moral truths were given to them by God to enlighten whole nations and to bring a higher level of understanding to individuals . . .
Consistent with these truths, we believe that God has given and will give to all peoples sufficient knowledge to help them on their way to eternal salvation, either in this life or in the life to come . . .
Our message therefore is one of special love and concern for the eternal welfare of all men and women, regardless of religious belief, race, or nationality, knowing that we are truly brothers and sisters because we are sons and daughters of the same Eternal Father.5
