When you say that he “rejected” these books, what do you mean?
He wanted them removed from the Bible all together along with the deuterocanicals. He did not believe they were the inspired word of God.
The only thing that kept him from removing them was his personal council of advisors.
He had is own idea as to what was inspired by God and what was not.
The book of James was detrimental to his “Sola Fide” stance because of the “Faith without Works is Dead” statement.
Revelation was even more detrimental since Jesus was more concerned about works than faith.
