As in physics, so in politics: for every action there is a reaction, perhaps not equal nor precisely opposite, but reliably contrary nonetheless.
–David M. Kennedy, Freedom From Fear: The American People in Depression and War, 1929-1945 (1999), p. 339
The Vatican is an imposing enough place to speak, especially for a Southern Baptist, so I guess I can plead that my mind was distracted with nervousness. I waited in line with several friends and colleagues of various communions and denominations to enter the center of the Church of Rome to attend a gathering, called by Pope Francis, of religious leaders from around the world to talk about marriage and family. Going through security, I fished in my coat pocket for my passport. The problem was that I had worn the same suit the week before, lecturing on the Protestant Reformation at an Evangelical seminary. Without thinking, I pulled out what I took to be my passport, only to find that I was handing the Swiss Guard a pocket-size copy of Martin Luther’s 95 theses.
As I made a fumbling attempt to put the little booklet away and find the right documentation, I wondered which of my grandparents would be more ashamed of me: my Roman Catholic grandmother, for my ushering the tumult of the 16th century right there to the pope’s door; my Baptist-preacher grandfather, for entering the Vatican at all; or all of my grandparents together — Evangelicals and Catholics alike — for my violation of southern manners. My awkwardness was all my own, though. The Swiss Guards didn’t recognize the 95 theses, and my American Catholic colleagues roared with laughter. At least I didn’t nail anything to a door.
