Mater Misericordiæ meaning Mother of Mercy

Whether you are new, just seeking information, or even if you’ve been away from the Church, we warmly welcome you to our parish. Mater Misericordiæ 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.

Why the Extraordinary Form?

This liturgy was in use before the Second Vatican Council

Using the ancient liturgy as our well-spring, we form our priests in the traditions of the Church to serve at the altar and in the parish so that the fullness of Christ might enter the emptiness of the world”
