1. My servant, Orson Hyde, was called by his ordination to proclaim the everlasting gospel, by the spirit of the living God, from people to people, and from land to land...reasoning with and expounding the scriptures unto them.2. And, behold and lo, this is an ensample unto all those who were ordained unto this priesthood, whose mission is appointed unto them to go forth--3. And this is the ensample unto them, that they shall speak as they are moved upon by the Holy Ghost.4. and whatsoever they shall speak when moved upon by the Holy Ghost shall be scripture, shall be the will of the Lord, shall be the mind of the Lord, shall be the word of the Lord, shall be the voice of the Lord and the power of God unto salvation.
At this point, Orson Hyde was a recently baptized convert, having been baptized only about one month prior to this calling and revelation. So it is not speaking of Apostles, which he later became, but of run-of-the-mill missionaries.
If whatsoever they speak is scripture, where is it recorded? Or is it somehow scripture only to the audience, and recorded only as a witness against them? Scripture will be one of the yardsticks against which we are measured when we face God at judgment, so perhaps what this means is that when we are judged, we will be faced with every spiritually inspired utterance that was ever spoken in our presence.
