My point to Rainy was that the source of Truth is God in three forms, the Father, the Son, and the Holy Ghost. Rainy said the Bible is the one source of truth. It is not the Bible that is the source of truth but the God that provided those revelations that we read in the Bible. In some way, we can equate the Bible to Christ, because Christ is the Word that we read in the Bible.
It is incorrect to say that the Bible is the source of truth. It is the Eternal Word who is Christ that is the source of all truth, some of that truth we are lucky enough to read in the Bible.
What you are writing is another subject I would have to know some of what these other books are saying before I could respond to you.
