As ambassador, Díaz helped launch the Religion in Foreign Policy Working Group of the Secretary of State's Strategic Dialogue with Civil Society. The Working Group facilitates regular dialogue between the U.S. foreign policy establishment and religious leaders, scholars, and practitioners worldwide on strategies to build more effective partnerships on issues such as conflict prevention, humanitarian assistance and national security.[3]
On May 20, 2014, Loyola University Chicago announced that they intended to hire Díaz as a professor despite a University of Dayton harassment allegation. A spokesman for Loyola said in an email, "We have reviewed the allegations raised against Miguel Diaz and our offer to him stands." He became a professor at Loyola on July 1, 2014.[5]
Conservative news outlet Newsmax claimed that Díaz was rejected by the Vatican several times. However, Time magazine said that the story was false.[9]
He presented his credentials on October 2, 2009, and served until November 10, 2012.[10]
Theology
Building on the work of Karl Rahner, Díaz has placed extensive emphasis on the role of the Trinity in history.[11] Along with theologians such as Catherine LaCugna, Díaz argues that the life of God cannot be considered apart from history, but must be conceived as "for us, and for our salvation." In this vein, he has also asserted that in the contemporary American context, God can be seen vividly "in the face of migrants," who face the dangers of economic insecurity, violence, and social marginalization in search of a better life.[12]
He received several honorary doctorates while serving as ambassador. [citation needed]
After joining the University of Dayton, he was sought for analysis and comment[16] by the national news media, especially upon the resignation of Pope Benedict XVI in February 2013. He currently holds the John Courtney Murray University Chair in Public Service at Loyola University Chicago where he continues to be sought by multiple media outlets for analysis and commentary.[17]
