About Diocese of Oakland

The Diocese of Oakland (Latin: Diœcesis Quercopolitana) is a Roman Catholic diocese in the San Francisco Bay Area serving Alameda and Contra Costa counties in California. Established on January 13, 1962, by Pope John XXIII, it was carved from the Archdiocese of San Francisco and is today a suffragan of that same archdiocese. The diocese is home to roughly 550,000 Catholics out of a total East Bay population of 2.8 million, and its striking Cathedral of Christ the Light on Lake Merritt — completed in 2008 — is one of the most architecturally celebrated modern Catholic churches in the United States. It is currently led by Bishop Michael C. Barber, S.J., a Jesuit and Navy Reserve chaplain who in 2013 became the first American bishop appointed by Pope Francis.

History of the Diocese of Oakland

The East Bay's Catholic roots run back to Mission San José, founded by Fermín de Lasuén in 1797 to evangelize the Ohlone (Chochenyo) people. After California became a U.S. state in 1850 and the Archdiocese of San Francisco was created in 1853, the East Bay remained part of that archdiocese for 109 years. Pope John XXIII erected the Diocese of Oakland on January 13, 1962 — carving Alameda and Contra Costa counties out of the San Francisco archdiocese and naming Auxiliary Bishop Floyd Begin of Cleveland as founding bishop. Bishop Begin chose the existing St. Francis de Sales Church as the cathedral, attended all four sessions of Vatican II, and saw the cathedral's music program become nationally known in the 1970s as the 'Oakland Cathedral Sound.' He died in 1977 and was succeeded by Bishop John Cummins, who shepherded the diocese through the catastrophic 1989 Loma Prieta earthquake. After 14 years and the decision to demolish the damaged cathedral, ground was finally broken in 2005 for the new Cathedral of Christ the Light on Lake Merritt, which was dedicated in September 2008. Bishops Vigneron, Cordileone, and the current bishop, Michael C. Barber, S.J., have led the diocese since 2003.

Cathedral of Christ the Light

The Cathedral of Christ the Light is the mother church of the Diocese of Oakland, sitting on a prominent two-block site overlooking Lake Merritt in downtown Oakland. Designed by Craig Hartman of Skidmore, Owings & Merrill and completed in 2008 at a cost of approximately $131 million, the 1,350-seat sanctuary is part of a 226,000-square-foot complex that includes a mausoleum (where Bishop Begin's remains are interred), conference center, administrative offices, the bishop's and clergy residences, a bookstore, café, parish hall, library, and parking. The building's plan is shaped like a vesica piscis — the ancient Christian symbol — and takes the form of an 'inner wooden vessel contained within a veil of glass.'

  • Architect: Skidmore, Owings & Merrill (Craig Hartman)
  • Form: vesica piscis — wooden vessel within a glass veil
  • Glulam structure: 52 curved Douglas fir ribs, 224 steel tension rods, 104 timber compression struts, 724 glulam louvers
  • Seismic engineering: 36 base isolators permit 30 inches of displacement; designed to withstand a 1,000-year earthquake just 2.9 miles from the Hayward Fault
  • Omega Window: 58-foot Christ image in anodized aluminum with 94,000 laser-cut perforations
  • Sustainability: fly-ash and slag concrete; daylight-only lighting except evenings; thermal mass radiant heating; designed for a 300-year life

He is a Knight of the Holy Sepulchre and a Magistral Chaplain of the Order of Malta, and speaks French, Samoan, Spanish, and Italian in addition to English.

Becoming Catholic (OCIA)

Through the Order of Christian Initiation of Adults (formerly RCIA), the Diocese of Oakland welcomes thousands of adults each year into a deeper relationship with God and into full communion with the Catholic Church. Parishes across the diocese offer OCIA formation for the unbaptized, those baptized in another Christian tradition, and already-Catholic adults seeking confirmation.

  • Sacraments of initiation at the Easter Vigil at the Cathedral of Christ the Light and at parish churches throughout the diocese

Faith Formation & Religious Education

The diocese's Faith Formation and Evangelization office supports lifelong Catholic education, coordinating religious instruction for over 45,000 students across the East Bay, youth ministry, adult formation, family life programs, and the Bishop's Ministries Appeal funding streams. The ethnic pastoral centers — African American, Asian Indian, Brazilian, Chinese, Eritrean, Ethiopian, Fijian, Filipino, Indonesian, Korean, Latino, Samoan, and Tongan — provide culturally rooted faith formation and Masses in more than a dozen languages.

Working through the diocese's parishes and pastoral centers, the Church delivers shelter, meals, counseling, refugee resettlement, housing counseling, school-violence intervention, senior services, job training, and emergency aid to more than 530,000 people of all faiths each year.

Safe Environment & Protection of Children

In the wake of the clergy sexual-abuse crisis, the Diocese of Oakland maintains a robust Safe Environment program. All clergy, employees, and volunteers with ongoing contact with minors must complete VIRTUS training, undergo Live Scan fingerprinting, and follow background-check protocols before beginning ministry, with retraining every three years. The Office of Victims Assistance provides counseling and support to survivors and their families. The diocese filed for Chapter 11 bankruptcy on May 8, 2023, in response to 330+ lawsuits filed under California Assembly Bill 218; a Plan of Reorganization filed November 8, 2024, would create a Survivors' Trust of $160–198 million for approximately 345 claimants, funded by diocesan cash, real-estate contributions (up to $81 million), insurance assignment, a $14.25 million contribution from the Roman Catholic Welfare Corporation/Schools, and outside loans. Catholic schools are separate legal entities and continued operating normally throughout the process.
