October 1, 1529 - Luther and Zwingli Debate

One dynamic of the Protestant Reformation was anyone and everyone could have an opinion on how to interpret Scripture instead of what the Church of Rome commanded. Two Protestant giants, Germany's Martin Luther and Switzerland's Ulrich Zwingli, squared off on October 1, 1529 for the Colloquy of Marburg to seek theological agreement on 15 points. While they agreed on 14 of 15 points, they could not be reached on the doctrine of substantiation and Luther stormed out and refused to shake Zwingli's hand.
