“I am deeply sorry for our becoming involved and readily accept the fact that I was the responsible one in our relationship,” Father O’Loghlen said in a five-page handwritten letter dated June 23, 1996. “Clearly, I was the one in power position. If I had not made a move nothing would have happened between us. I sincerely hope that there were some moments of joy for you in our relationship, but ultimately it caused you much significant pain.”

Father O’Loghlen goes on to say that since Ms. Malcolm filed her complaint, he has undergone psychological evaluations, which determined that he is “not a pedophile” or a “sexual predator.” But, he adds, “I do have a sexual addiction.”

Copies of the letter and other documents were provided to The New York Times by Joelle Casteix, the southwest director of the Survivors Network of those Abused by Priests, who had received them from Ms. Malcolm.

Father O’Loghlen, 74, was ordained in Ireland in 1961. He began teaching at Bishop Amat later that year and remained there for six years. In 1967, around the same time of his involvement with Ms. Malcolm, he moved to Damien High School, a boys’ school nearby, where he was vice principal and principal for more than 10 years.

In 1995, Father O’Loghlen became the provincial leader in the western region for the religious order of the Congregation of the Sacred Hearts of Jesus and Mary. After he contacted Ms. Malcolm in 1996, leaders in the Los Angeles Archdiocese and officials with the religious order based in Rome exchanged several letters.

According to copies of those letters, Father O’Loghlen admitted to molesting Ms. Malcolm and told his superiors that he was undergoing counseling. Msgr. Richard Loomis, then the vicar for clergy in Los Angeles, told officials in Rome that he would not remove Father O’Loghlen from the archdiocese but that his service should be limited.

Several months later, Monsignor Loomis removed all restrictions on Father O’Loghlen and, in a letter, thanked him for agreeing to serve on the sexual abuse advisory board. He writes that both he and Cardinal Mahony “feel that you will bring valuable insights to the work of the board.”
