D'Arcy attended the Pontifical University of St. Thomas Aquinas in Rome from 1965 to 1968, earning a doctorate in spiritual theology.
But Bishop D'Arcy's 1984 letter to Archbishop Bernard Francis Law about Geoghan’s history of abusing young boys did no good.
In March 2009, D'Arcy declared he would boycott the May graduation ceremony at the University of Notre Dame because President Barack Obama would be delivering the commencement speech and receiving an honorary degree.
"[2] Pope Benedict XVI accepted D'Arcy's resignation as bishop of Fort Wayne-South Bend on November 14, 2009.
John D'Arcy died on February 3, 2013, in Fort Wayne, Indiana, from lung and brain cancer at age 80.
