My family and I are on a three-week vacation in the Republic of Ireland and Northern Ireland. As we planned our trip, my wife and I felt somewhat nervous upon realizing that we and our two young daughters would be staying in the resort coastal town of Portrush, near Giant’s Causeway and the Old Bushmills Distillery in County Antrim, on the 12th of July.

The 12th is the annual commemoration by Protestants in Northern Ireland of William of Orange’s victory over James II. Tension and conflict have accompanied the marches, especially during the 30-year-long Troubles. After the Good Friday Agreement in 1998, the violence decreased significantly. But after centuries of mutual fear and antipathy, change takes time.

They say that everyone has an Ian Paisley story. My own memorable encounter with the leader of the Democratic Unionist Party occurred in 2000 at Storemont in Belfast. Gordon Shea and I were there with 20 students from Simpson College, and we had a private audience with Paisley to hear his perspective on the Troubles.
