At the heart of Quezon City lies the Vicariate of the Holy Family, a dynamic cluster of parishes under the Diocese of Cubao dedicated to fostering faith-filled families and vibrant Christian communities. Named after Jesus, Mary, and Joseph, the Vicariate embodies the Church’s mission to nurture the family as the “domestic Church”—a small yet powerful sanctuary where faith begins, grows, and is lived out daily. A church under this vicariate is the Immaculate Conception Cathedral of Cubao, the mother church and seat of the Diocese.
