John Allen explores this question in a recent article. Archbishop Edwin F. O'Brien is the 15th archbishop of Baltimore, a New York native, and an affable man with a prayer life and a sense of humor. A former spiritual father of mine worked with the archbishop at the North American College (Rome) and spoke very highly of O'Brien's character, ability to work and his capacity for friendship.
Aside from heading America's premier diocese, O'Brien is a good shepherd, asking the hard questions and quickly becoming a significant voice for Catholics in America.
