D&C 52

As the Lord declares that he will give unto a "a pattern in all things", in regards to teaching the gospel, he instructs -

"...let them journey from thence preaching the word by the way, saying none other things than that which the prophets and apostles have written, and that which is taught them by the Comforter through the prayer of faith."  (Doctrine and Covenants 52:9)

"...according to the revelations and truths which I have given you."  (Doctrine and Covenants 52:17)

"...declaring none other things than the prophets and apostles, that which they have seen and heard and most assuredly believe,"  (Doctrine and Covenants 52:36)

I becomes clear that the Lord wants us to teach that which is in scripture and modern day apostles and prophets.
