Not at all; if one follows the Scripture and omits his own "views", he has a perfect body of knowledge for doctrine, reproof, instruction in righteousness, etc. Scripture is never wrong, but man is more wrong than right.
Tell me -- of the Baptists, Methodists, Lutherans, Congregationalists, Catholics, Greek Orthodox, Russian Orthodox, and Copts ... how did they have such a much harder time figuring out correct doctrine? You seem to have it all nailed down pretty firmly ...
