Wuerl is the fifth Archbishop of Washington elevated to cardinal since the archdiocese was created out of the Archdiocese of Baltimore. The others were Patrick A. O'Boyle, William W. Baum, James A. Hickey and Theodore E. McCarrick.Wuerl joined the archdiocese in 2006 after 18 years as bishop of Pittsburgh. In 2008, he hosted Benedict during the pope's visit to Washington. Last month, he released Disciples of the Lord: Sharing the Vision, a pastoral letter calling upon Catholics to renew their faith as part of a new evangelization. Earlier this week, he announced the archdiocese will open a new seminary next fall to accommodate an increase in the number of seminarians in college and pre-theology studies.
