Rev. Robert Drinan, an internationally known human rights advocate, Jesuit priest, lawyer, and former U.S. Congressman, died Sunday after a long illness. He was 86.

Father Drinan, professor at the Georgetown University Law Center, authored thirteen books, including  Can God and Caesar Coexist?: Balancing Religious Freedom and International Law and The Mobilization of Shame: A World View of Human Rights, published by Yale University Press.

He was awarded the American Bar Association Medal in 2004, the organization’s highest honor for service to the cause of American jurisprudence, and received the Distinguished Service Award last May from then-Speaker Dennis Hastert and then Minority Leader Nancy Pelosi on behalf of the U.S. House of Representatives.

Former U.S. President Jimmy Carter wrote of “The Motivation of Shame” – “Father Drinan’s credentials as a humanitarian, religious leader, and thinker are unassailable. . . . His astute grasp of practical solutions to world problems enables him to debate policy as a scholar and practitioner, as well as a religious leader.”
