Really, you don't understand the sources where revelations are recorded in the Church? I thought you said you were a returned missionary. Oh well.
Revelations are recorded in the Church in four books. We refer to them as the Standard Works: The Holy Bible, The Book of Mormon, Doctrine and Covenants, and The Pearl of Great Price. Within the pages of those books you will find very little regarding the topics you raised. You will find more commentary and ****ysis of those revelations in books such as Gospel Principles, but Gospel Principles is not a book of revelations. That is why I say that very little has been revealed. Hope that helps.
