Does The Utah Doctrine And Covenants Section 121 Pass This Test?

The text that now comprises section 121 of the Utah Mormon Doctrine and Covenants was taken from a letter signed by Joseph Smith, Hyrum Smith, Lyman Wight, Caleb Baldwin, and Alexander McCrae while they were imprisoned in the Liberty jail. This letter was first published in Vol. I, Number 7 of the Times and Seasons in May of 1840. It did not become part of the Utah Mormon canon of scripture until 1876, and when the differences between the two printings are compared, it is not difficult to see why. Consider the following:

It has never been established who the author of these changes to the text of the original was, but one thing is certain, Joseph Smith was not. The original printing of this letter occurred early enough in the Nauvoo period for Joseph Smith to have made any corrections. However, the evidence is clear that due to the nature of the changes which were made to this letter, it is difficult to comprehend why Joseph would have allowed the text to read as it did in the original if he really believed in the concept of many gods. The fact that Joseph Smith taught the concept of only one God during his life should sufficiently prove that he was not responsible for the changes to this text.
