The annual Priests’ Alumni Mass at St. Charles Borromeo Seminary drew scores of priests of the Philadelphia Archdiocese — many celebrating 25 years, 50 years or more — to St. Martin’s Chapel at the seminary on Thursday, May 2. Archbishop Charles Chaput was the main celebrant for the Mass, and he joined priests for a meal after the Mass. See our list of the men celebrating the anniversary of their priestly ordination here.
