Elder Bruce R. McConkie (1915–85) of the Quorum of the Twelve Apostles indicated what comprised the true doctrine of Christ: “The true doctrine of Christ is that all men must come unto him, gain faith, repent, be baptized, receive the Holy Ghost, and endure in faith to the end in order to gain salvation. (2 Ne. 31:17–21; 3 Ne. 11:29–41; D.&C. 10:67; 68:25.)” (Mormon Doctrine, 2nd ed. [1966], 204).
President Boyd K. Packer, President of the Quorum of the Twelve Apostles, made this statement regarding the power of true doctrine:
“True doctrine, understood, changes attitudes and behavior.
“The study of the doctrines of the gospel will improve behavior quicker than a study of behavior will improve behavior. … That is why we stress so forcefully the study of the doctrines of the gospel” (in Conference Report, Oct. 1986, 20; or Ensign, Nov. 1986, 17).
