St. Mary's is here to bring Jesus Christ to His people and to bring His people to Him. Our parish is dedicated to proclaiming Jesus Christ in sacrament, word and deed. We are an active parish grounded in the Eucharist and immersed in the Gospel.  We are guided by Scripture and Tradition and directed by the Magisterium of the Church. Through these means we teach, preach and hold the Gospel of Jesus Christ.
