We've all (except BCSpace) noticed that the church has been repudiating its past teachings with alarming regularity in recent years, calling the words of past Prophets, Seers, and Revelators the speculative teachings unsupported by scriptural doctrine.
You've never provided any examples. The Adam God hypothesis never panned out for example.
Stapley: The Papers’ General Editors wrote in the introduction to Journals 1 that the project “gathered every known Joseph Smith document” for publication. I noticed in note 30 of page 61 that it indicated that several patriarchal blessings delivered by Joseph Smith will be published in future volumes. Will the Patriarchal Blessing Book have a volume of its own? Note 47 on page 67, which introduced the Kirtland Egyptian Papers (KEP), did not carry a similar indication. Will the KEP be published, and if not why would they not be considered a Joseph Smith Document? The Nauvoo Council of Fifty Minutes are another document that folks (myself included) have pointed to as not being definitively commented on for inclusion.
Mark: We classify the patriarchal blessings given by Joseph Smith Jr. as Joseph Smith texts and will include them in the Documents series. Some of the KEP material has Joseph Smith handwriting and therefore meets our criteria for document inclusion. So this material will also appear in the Documents series. Other KEP manuscripts do not contain Joseph Smith’s handwriting and are of uncertain authorship. Because these documents do not meet our criteria they will not be included in the Documents series. It is possible that they will appear later down the road as auxiliary material in a Book of Abraham volume in the Revelations and Translations series. We haven’t gotten that far yet. Same with the Council of 50 minutes.
Not including manuscripts that "do not contain Joseph Smith’s handwriting and are of uncertain authorship" is a pretty poor excuse. Anything that was recorded by a clerk or secretary in the Council of Fifty was undoubtedly done under the direct supervision of Joseph Smith. Are the First Presidency embarassed by the teachings of Joseph Smith in the Council of Fifty minutes? If not, then why sit on them and never allow them to see the light of day?
