Revelation to Joseph Smith, jr. Oliver Cowdery, and John Whitmer. Given at Harmony, Penn. July, 1830.
Behold I say unto you, that you shall let your time be devoted to the studying of the scriptures, and to preaching, and to confirming the church at Colesville; and to performing your labors on the land, such as is required, until after you shall go to the west, to hold the next conference and then it shall be made known what you shall do. And all things shall be done by common consent in the church, by much prayer and faith; for all things you shall receive by faith. Amen.
Shortly after we had received the above revelations, Oliver Cowdery returned to Mr. Whitmer's, and I began to arrange and copy the revelations which we had received from time to time; in which I was assisted by John Whitmer, who now resided with me. Whilst thus (and otherwise at intervals) employed in the work appointed me, by my heavenly father, I received a letter from Oliver Cowdery, the contents of which gave me both sorrow and uneasiness. Not having that letter now in my possession, I cannot, of course, give it here in full, but merely an extract of the most prominent parts, which I can yet, and expect long to remember. He wrote to inform me that he had discovered an error in one of the commandments: Book of Doctrine and Covenants, Sect. 2d, page 7th-"And truly manifested by their works that they have received of the spirit of Christ unto the remission of their sins." The above quotation, he said, was erroneous, and added, I command you in the name of God to erase these words, that no priestcraft be amongst us!! I immediately wrote to him in reply, in which I asked him by what authority he took upon him to command me to alter or erase, to add or diminish to or from a revelation or commandment from Almighty God. In a few days afterwards I visited him and Mr. Whitmer's family, were [where] I found the family, in general, of his opinion concerning the words above quoted; and it was not without both labor and perseverence [perseverance] that I could prevail with any of them to reason calmly on the subject. However Christian Whitmer at length got convinced that it was reasonable, and according to Scripture, and, finally, with his assistance, I succeeded in bringing, not only the Whitmer family, but also Oliver Cowdery, to acknowledge they had been in error, and that the sentence in dispute was in accordance with the rest of the commandments. And thus was their error rooted out, which having its rise in presumption and rash judgment, was the more particularly calculated (when once fairly understood) to teach each and all of the necessity of humility and meekness before the Lord, that he might teach us of his ways, that we might walk in his paths, and live by every word that proceedeth forth from his mouth.
