A false Christ is not a person. It is a false system of worship, a false church, a false cult that says: ’Lo, here is salvation; here is the doctrine of Christ. Come and believe thus and so, and ye shall be saved.’ It is any concept or philosophy that says that redemption, salvation, sanctification, justification, and all of the promised rewards can be gained in any way except that set forth by the apostles and prophets. (Millennial Messiah, pp. 47-48.)
“False Christs”
In speaking of the rise of false Christs in our own generation, Elder Bruce R. McConkie has written: “True there may be those deranged persons who suppose they are God, or Christ, or the Holy Ghost, or almost anything. None but the lunatic fringe among men, however, will give them a second serious thought. The promise of false Christs who will deceive, if it were possible, even the very elect, who will lead astray those who have made eternal covenant with the Lord, is a far more subtle and insidious evil.”
