Whether you are new to or visiting our area, seeking information on the Catholic Church, or if you’ve been away from the Church for a long time, we warmly welcome you to Mater Misericordiæ parish. Mater Misericordiæ (Mother of Mercy) glorifies God, uniting its members in faith, hope and charity through profession of the One Holy Catholic and Apostolic Faith and through participation in the Sacraments and Traditional Rites of the Missale Romanum of 1962, under the governance of the Bishop of the Roman Catholic Diocese of Phoenix and the Priestly Fraternity of Saint Peter.
