In my book The Jesus Paradigm, I devote an entire chapter to the Anabaptists, those radical reformers of the 16th century. I've learned a great deal from these valiant believers, not least that there comes a time when you have to become your own teacher, your own guide, even your own pastor. The word of God alone is your best authority. We must therefore develop a healthy distrust of the experts. The Anabaptists turned away from Zwingli not because they disrespected him but because they respected God's word more.
