We invite you to join the entire Cathedral High School community to celebrate Mass to launch our academic year in prayer. The Mass of the Holy Spirit is a centuries-old tradition in Catholic educational institutions when we pray for the guidance and wisdom of the Holy Spirit for our students and faculty and school.

All parents, alumni, benefactors, partners, and neighbors are warmly welcomed. The Mass of the Holy Spirit will be celebrated by Very Rev. Kevin J. O’Leary, rector of the Cathedral and school trustee at 10 a.m. in Our Lady’s Chapel on the lower level of the Cathedral of the Holy Cross. We highly recommend guests arrive early as seating is limited due to the renovations at the Cathedral.
