He shaped the Catholic Church's stance on nuclear weapons in the '80s. What he makes of this moment

Father J. Bryan Hehir, a top official in the Catholic Archdiocese of Boston, articulated a global off-ramp from nuclear apocalypse in a 1983 letter with the U.S. Conference of Catholic Bishops. That letter, which laid out a vision of slow global disarmament over time, served as a model for policy throughout the world.

Hehir joins WBUR's Morning Edition to discuss the war in Iran and the role of the Catholic Church in this moment.
