Let me suggest that, as the Reformation quincentennial approaches, Catholics ought to try to think about why so many, then and now, felt the necessity of the Reformation. Conversely, Protestants ought to consider why Catholics, then and now, have perceived it as tragic. That might not answer all questions, mend all divisions. But it might not be a bad place to start.
But, esteemed reader, let me close with a question: how do you think the Reformation ought to be commemorated in 2017?
