Join Mater Dei


The Mater Dei Community has the use of the historic St. Lawrence Chapel in downtown Harrisburg. Bishop Rhoades also appointed a full-time chaplain, assigned from the Priestly Fraternity of St. Peter, to provide for the pastoral needs of the Mater Dei Community. With the ministry of this chaplain, the Community has the offering of the Holy Sacrifice of the Mass on a daily basis, as well as the celebration of all the sacraments and the other rites of the Church according to the Missal and ritual books of Pope Saint John XXII.
