Other than the Bible, which I have been told is considered corrupted, the Book of Mormon is the key source of spirituality or am I wrong???
The Bible was not completly translated correctly so, Joseph Smith went back through and with the power of God was able to fix the errors in the book. The Book of Mormon is our key book for spirtual guidence, but we use the Bible as well
Article of Faith 8:
We believe the aBible to be the bword of God as far as it is translated ccorrectly; we also believe the the dBook of Mormon to be the word of God.
How important is the Pearl of Great Price to Mormons and their doctrines?
The Pearl of Great Price is important to our doctrine. In Moses, it gives us the reason for the creation on top of the creation itself. In Abraham, it is a record of Abraham, The first patriarch in the Jewish religion, that same man.
Is there a third book that is spiritually important or is it only two?
Yes, the books were study out of are: The Book of Mormon, The Bible (KJV), The Pearl of Great Price and The Doctrine and Covenants. We each hold them in the same regard as each other. All is doctrine.
Also, on top of that, the words of our modern day prophets are considered scripture so we read their talks in a magazine called the Ensign(aimed for adults), New Era (aimed for youth), and the Friend (aimed for kids)
