I have a question: THere is the book of Mormon, D&C......and what else is considered set in stone? Because so much of what Mormon's believe is NOT in the BOM, does it come from subsequent revelations of J.Smith? ie) God was once a man.
When I was active LDS, all published or broadcast General Conference talks were considered "scripture." Those can be found in the Church Magazines.
In the earlier days the talks of the Prophets were recorded in the Journal of Discources. Now we see that the Church is repudiating them as "unofficial."
There are actually only three official Mormon publications that no Mormon will refute. The D&C, Book of Mormon and the Pearl of Great Price. They can be purchased in one book called the triple combination.
The P of GP has had new light shed on it in recent years. This is the supposed Joseph Smith translation of Egyptian papyri...the Book of Abraham etc. It appears that the papyri was just a simple funerary piece that was included in a sarcophagus w/ a mummy.
