Some of the most exquisite stained glass windows in the United States filter light at the Saint Vincent De Paul Church in Bayonne, NJ. The Catholic church was predominantly constructed by Irish men and women in this working-class town, situated across the river from Manhattan, in 1894. During the 1920s, an innovative priest at the church hired a craftsman named Harry Clark from Ireland to design the 40 windows in the church, centered around the concept of suffering. The church's historian, Peter Keenen O'Brien, conversed with ReligionUnplugged.com's executive editor, Paul Glader, regarding the church and its windows.
