The Holy Spirit is the Author of the Book that informs us of the identity of the real, historical Jesus. Scripture works hard to set forth the real Christ. The creeds are merely attempts to preserve this biblical portrait and to protect it from distortions. When a person says, “All I need to know is Jesus – doctrine isn’t important,” we should immediately ask in reply, “Who is Jesus?” The moment a person begins to answer that question; the person is inescapably involved with doctrine.
