Reformation 500: Zwingli’s turn to ‘sola scriptura’

When I was younger, I gave myself overmuch to human teaching, like others of my day, and when about seven or eight years ago I undertook to devote myself entirely to the Scriptures I was always prevented by philosophy and theology. But eventually I came to the point where led by the Word and Spirit of God I saw the need to set aside all these things and to learn the doctrine of God direct from his own Word. Then I began to ask God for light and the Scriptures became far clearer to me.
