As I have pointed out in recent talks, if you were to be taught by an angel of God it would be a lesson in the scriptures. (See, e.g., JS-H 1: 36-41.) The day the Lord was resurrected He spent the better part of the day expounding the scriptures to two of His followers. (Luke 24: 13-32.)
I teach from the scriptures because they contain everything needed to support, explain, justify and make clear those doctrines which are needed for your salvation. Even the deepest of material I’ve given to you is anchored in the scriptures.
If angels and our Lord all found the scriptures a sufficient text to use in teaching truths, then we should look there, searching deeply for any truths we want to learn. We shouldn’t move our attention away from the scriptures to learn what is needed for salvation and exaltation. No matter how much a topic glitters and begs you to notice it, the scriptures should form a shield to keep away what is unnecessary and save you from unreliable error.
The more exotic the “spiritual” information, the more important it is to find a home in the scriptures. This is because if it cannot be found there, then it does not belong to Christ’s Gospel.
In the traditions of the church, we have added speculation to conjecture, and contradiction to supposition, until the present array of approved topics through the correlation process has been adopted to try to bring an end to the chaos of opinions. Earlier teachings that were thought to be critical to salvation have been abandoned. Earlier practices that were taught as necessary for exaltation are now condemned. Earlier positions on practices and church government are now renounced. It has become an embarrassment to the institution to allow this foolishness to continue. They have resorted to correlation and the current practice of saying “only the living mouthpiece is reliable.” This is anti-historical and renders each leader almost entirely irrelevant as soon as he dies. Mormonism has been reduced to the medieval shout: “The king is dead! Long live the king!” each time a church president dies. Through this means, the church is attempting to bring stability to a reed so thin it cannot be leaned upon at all for your salvation. It will break because it cannot support the weight of your salvation.
Look to the scriptures. They testify of Christ. They were given by Him to teach you of Him. Because if you are to be saved at all, it will be through the knowledge which can be found in the scriptures.
Anyone attempting to save souls who neglects to anchor their teaching in the scriptures offends common sense, and is attempting the impossible. Angels and the risen Lord used them. You should therefore find them sufficient for your own study unto salvation.
