A Place
for Everyone

With 58 churches, 5 centers and 36 schools within our diocese, we have a seat for you.

Our vibrant community of 1.3 million Catholics is on a journey of faith together – growing closer to God and another as we explore, experience, and share the mystery of Christ. Under the leadership of Bishop Kevin W. Vann, the OC Diocese works to establish and support dynamic, vibrant parishes and schools welcoming all to live the Gospel with faith, joy, charity and unity. We joyfully welcome you as part of this journey!

Visit the St. Callistus Chapel and Crypts

The final phase of Christ Cathedral’s transformation has been completed with the opening of the St. Callistus Chapel and Crypts! The chapel is named in honor of the original St. Callistus parish, which moved to Christ Cathedral when the property was acquired by the diocese.

The Romano-Byzantine-style chapel, located beneath Christ Cathedral, was blessed and dedicated on October 14, the feast day of St. Callistus I. The chapel and crypts is now open to the public. Book a tour at the link below!

Fr. Ian's Homilies: "The Father's Loud Cry"

“And beginning with Moses and all the prophets, [Jesus] interpreted to them in all the Scriptures the things concerning Himself” (Luke 24.27)—and in doing so, Jesus shows us that the scriptures are about Himself. Convicted by this truth, Fr. Ian preaches every weekend the mystery of Christ as revealed in the Sunday readings. It is Jesus who we seek—and in these homilies, Fr. Ian hopes to provide a glimpse of Him. Father Ian is a Roman Catholic Priest serving at Christ Cathedral in the Diocese of Orange in California.

Laura recently authored a book entitled “Guided by Grace – A Catholic Journey Through Wills, Trusts and Estate Planning.” This book was borne out of a medical crisis with her firstborn son that challenged the Meier family to the core. You are sure to be inspired by her compelling story. Please share this podcast!
