John Stephen Cummins

On April 4, 2004, Cummins testified for the plaintiffs in a sexual abuse lawsuit against the Diocese of Oakland. The plaintiffs were two brothers, Bob and Tom Thatcher, who charged that Robert Ponciroli, a priest at St. Ignatius Parish in Antioch, California, molested them when they were minors in the early 1980s. Cummins said that he learned about allegations against Ponciroli in 1995, but did not notify police or try to find the victims. Cummins apologized for his failure to search for the victims. In 2016, Cummins published the book Vatican II, Berkeley and Beyond, a collection of reflections on the Vatican II Council and its effects on the church.

After reaching the mandatory retirement age of 75 for bishops, Cummins resigned as Bishop of Oakland on October 1, 2003. That same day, Saint Mary's College of California in Moraga, California, announced that Cummins would be working in the newly established John S. Cummins Catholic Institute for Thought, Culture and Action.

In February 1982, Cummins wrote to Cardinal Joseph Ratzinger, then head of the Congregation for the Doctrine of the Faith, forwarding a request from Stephen Kiesle, a priest in the diocese, to be laicized. Kiesle had been convicted of misdemeanor lewd conduct with a child in 1978 and had been suspended by the diocese from ministry. After a request from the Vatican in 1982 for more documentation, Cummins heard nothing from Ratzinger until 1985, when Cummins was told the matter would take more time. Kiesle was finally defrocked in 1987.

Cummins served as chairman of the USCCB Liturgy Committee (1981–84), the Laity Committee (1988–91), and the Migration and Refugee Services Committee (1995–98). From 1992 to 1995, he was co-chair of the Roman Catholic-Reformed-Presbyterian Dialogue Commission and a consultant of the Ecumenical and Religious Committee. Cummins was president of the California Catholic Conference from 1988 to 1997. He was chairman of the Catholic Legal Immigration Network, Inc. (CLINIC) from 1995 to 1999, and served as a delegate to several synods in Rome.

Cummins continued to serve as chancellor until 1971, when he was named executive director of the California Catholic Conference. In that capacity, he channeled the functions of the conference by providing liaison with state departments and with the California State Legislature, disseminating information to Catholic associations and organizations and to other state conferences and the United States Catholic Conference (USCCB) and coordinating interdiocesan activities in the areas of education and welfare.
