As most of my readers will be aware, Martin Luther nailed his Ninety-Five Theses to the door of a Church in Wittenberg, Germany on this day, five hundred years ago.
No informed Catholic should deny that there were very serious problems in the Church in the time leading up to the Reformation. To see this, we need only read what Teresa of Avila, John of the Cross, or any of the other Counter-Reformation saints had to say about the abuses they saw and the opposition they faced when they tried to correct them. We could also look at the reforms of the Council of Trent, or the biographies of Renaissance Popes for examples of corruption within the Church.
On the other hand, no serious Protestant should deny that the Reformation led to a fracturing of the Church and a proliferation of conflicting theologies that none of the original Reformers would agree with. I don’t think many Protestants would want to defend the purity of Henry VIII’s motives in breaking the Church of England away from Rome. And Luther, Calvin, and Zwingli soon found themselves divided against each other almost as much as against Rome.
Also, everyone hated the Anabaptists.
