The following was taken from a post by hoserb2k from reddit:
In case you were not watching confrence closely, near the end of Bednar’s “load” speech, he proclaimed that April 6th was known to be Jesus’s birthday by “revelation” (link, go to 15:28 )
The problem with this statement is that the April 6 date was not revelation, but rather mormon fokelore. While some point to D&C section 20 1) The revelation was given on April 10, not on the 6th like the scriptures claim and 2) The bit about April 6th was the addition of a scribe later on as an embellishment. What is the source of all this? Some terrible anti source like mormonthink.com? Try the church’s newspaper, Desert News
Well you say, there must have been some later revelation by a Prophet and Seer that confirms that the 6th really was the date. You would be incorrect, in fact Prophets and Seers are on the record as not agreeing. Here are some mormon luminaries weighing in on the issue:
James Talmage: April 6, meridian of time
J. Reuben Clark: Early December, 4 or 5 B.C.
Bruce R. McConkie: December 5 B.C.
In modern LDS history, both the clergy and the academics of the the church have pushed away from the 6th date as impossible (BYU Studies ).
I know that the general membership does not really care about this, but among the LDS historians and thinkers, this was a huge punch to the gut. The problematic april 6th date had been neatly solved for decades, and in a few seconds bednar again tears open the problem. You can head to the faithful sub and see how the debate will go (some upset, most rebuking them saying “how is this relevant to your salvation?”). A good friend of mine gasped when he heard bednar say this, and was convinced that it would be edited out of the conference report as an error. He was devastated when the report came out today and it remained in.
My point in bringing this up is that some LDS members really do care about facts, and do notice when events are misrepresented. As someone else posted, LDS editors notice when conference speakers steal quotes, and historians notice when you mess with history.
There you have it, B.S. from the pulpit in conference. Accountability? None.
