The Most Reverend John O. Barres, STD, JCL is the fifth Bishop of the Diocese of Rockville Centre (Long Island, NY). Previously, he served as the Bishop of the Diocese of Allentown (PA) from 2009 to 2016. He is a graduate of Phillips Academy (Andover), Princeton University, and the New York University Graduate School of Business, and holds advanced theological degrees from The Catholic University of America and the Pontifical University of the Holy Cross in Rome. Bishop Barres serves as the Vice Chair of the Board of Trustees of The Catholic University of America. His Episcopal motto “Holiness and Mission” is taken from Pope Saint John Paul II’s encyclical Redemptoris Missio, which emphasizes the universal call to holiness and mission in the Catholic Church. It also expresses Bishop Barres’ commitment to Pope Leo XIV’s emphasis on global Catholic missiology and evangelization and the call for a “missionary conversion” of Catholic parishes and every dimension of Catholic life and witness to the world.
