Our parish was established on January 1, 2015. Pope St. John XXIII, who promulgated the Roman Missal of 1962 which is used in our Masses, was chosen as our patron by Bishop Zubik. Previously, the “Latin Mass Community of St. Therese of Lisieux” was, since 1994, part of Holy Wisdom Parish.

The Institute of Christ the King Sovereign Priest is a Society of Apostolic Life of Pontifical Right whose goal is the honor of God and the sanctification of priests in the service of the Church and souls. Its specific aim is missionary: to spread the reign of our Lord Jesus Christ in all spheres of human life. Our work is carried out under the patronage of the Immaculate Conception, to Whom the Institute is consecrated.
At the gracious invitation of His Excellency, Bishop David Zubik, the Canons of the Institute of Christ the King have been providing for the pastoral care of St. John XXIII quasi-parish since October 15, 2018.
