"Old St. Patrick’s Church: A Chicago Renaissance Story" tells the story of how visionary leaders transformed the landmark Old St. Patrick’s Church from an empty church in a declining neighborhood into a Chicago hub of worship, culture, social life, education, and service. Old St. Patrick’s renaissance revitalized a then-struggling West Loop. The ongoing local vitality and global impact of this small urban church reveal the power of inspiration and imagination. Chicago Tonight will talk to the pastor who started the turn-around and the current priest who keeps the congregation growing.
