Mormon doctrine,

This work on Mormon Doctrine is designed to help persons seeking salvation to gain that knowledge of God and his laws without which they cannot hope for an inheritance in the celestial city.Since it is impossible for a man to be saved in ignorance of God and his laws, and since man is saved no faster than he gains knowledge of Jesus Christ and the plan of salvation, it follows that men are obligated at their peril to learn and apply the true doctrines of the gospel.This gospel compendium will enable men, more effectively, to "teach one another the doctrine of the kingdom"; to "be instructed more perfectly in theory, in principle, in doctrine, in the law of the gospel, in all things that pertain unto the kingdom of God, that are expedient" for them "to understand." (D. & C. 88:77-78.)
