A sampling of the 12,000 pages suggests that Cardinal Mahony and other top church officials dealt with the accusations of abuse regularly and intimately throughout the last several decades. It often took years to even reach the realization that a priest could no longer simply be sent to a rehabilitation center and instead must be removed from ministry or even defrocked.

In one case, the Rev. José I. Ugarte was accused by a doctor of having drugged and raped a young boy in a hotel in Ensenada and of taking boys every weekend to a cabin in Big Bear. But rather than turn Father Ugarte over to the authorities, Cardinal Mahony decided to send him back to Spain, made him sign a document promising not to return to the United States without permission for seven years, not to celebrate Mass in public and to seek employment in “a secular occupation in order to become self-supporting.”

The current archbishop, José H. Gomez, who succeeded Cardinal Mahony when he retired two years ago, took the unusual if not unprecedented step on Thursday night of censuring his predecessor, calling the documents he released late Thursday “brutal and painful reading” and announcing that he was removing him from administrative and public duties. He also accepted the resignation of one of his auxiliary bishops, Thomas Curry.

But in an extraordinary public confrontation between bishops, Cardinal Mahony adamantly defended himself on Friday, posting on his blog a letter he had sent to Archbishop Gomez. The cardinal insisted that his approach to sexual abuse evolved as he learned more over the years, and that his archdiocese had been in the forefront of reforms to prevent abuse and respond to victims.

Cardinal Mahony implied that his successor’s censure of him was unexpected and unwarranted: “Not once over these past years did you ever raise any questions about our policies, practices or procedures in dealing with the problem of clergy sexual misconduct involving minors.”
