DC 85:21b And I give unto you a commandment, that you shall teach one another the doctrine of the kingdom; teach ye diligently and my grace shall attend you, that you may 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 is expedient for you to understand;
DC 94:3d that they may be perfected in the understanding of their ministry; in
theory; in principle and in doctrine; in all things pertaining to the kingdom of God on the earth, the keys of which kingdom have been conferred upon you.
