It looks like to me there are page references. Notice the numbers before the “NCBE” which follows some of the words. Also, there are other ending letters which are also duplicated. These endings must be a reference to a page out of some obscure book he had. Then what he did was take a sentence and each letter was assigned a letter in the alphebet.
—Just my guess.
I think the reference to a book is the key. Find the book and the code will break Maybe NCBE is a book? What book has four words in the title with each word starting with NCBE? New Christian Bible ???
