What is Doctrine?

David A Bednar Quorum of the Twelve Apostles

A gospel doctrine is a truth of salvation revealed by a loving Heavenly Father.  Gospel doctrines are eternal, do not change, and pertain to the eternal progression and exaltation of Heavenly Father's sons and daughters.  Doctrines such as the nature of the Godhead, the plan of happiness, and the Atonement of Jesus Christ are foundational, fundamental, and comprehensive.

Gospel doctrines answer the question "why?" For example, the doctrine of the plan of happines answers the questio of why we are here upon the earth. . . .

A gospel principles is a doctrinally based guideline for the righteous exercise of moral agency. Principles provide direction. Correct principles always are based upon and arise from doctrines, do not change, and answer the question of "what?"  Many principles can grow out of and be associated with a single doctrine. . . A principle is not a behavior or a specific action. Rather, principles provide basic quidelines for behavior and action.  (Act in Doctrine [2012], pp. xiv-xv)
