It [the Amica Exegesis] appeared February 28, 1527. The Frankfort Fair was the great book mart. Zwingli, like Luther, made nothing from his publications. In which respect he resembled most modern authors, only he expected nothing! He once wrote to Vadianus (May 28, 1525, vii., 398): “There was a man lately who said that I sold copies to the printers at a high price. That man lied against the Holy Spirit. It must not be permitted therefore that this can be said with truth. I ask nothing than that they commend me to the Lord Jesus Christ.”
Publishing for the sake of disseminating the truth. What. A. Concept. Writing to instruct rather than become rich and famous. Just. Imagine.
1Jackson is wrong about the date- the Amica Exegesis appeared on the 8th of February, not the 28th. Huldreich Zwingli: The Reformer of German Switzerland (1484–1531).
