Philip Fabian Flynn led a remarkable life, bearing witness to some of the most pivotal events of the twentieth century. Flynn took part in the invasions of Sicily and Normandy, the Battle of Aachen, and the Battle of the Hurtgen Forest. He acted as confessor to Nazi War Criminals during the International Military Tribunal at Nuremberg, assisted Hungarian revolutionaries on the streets of Budapest, and the waves of refugees arriving in Austria fleeing the effects of ethnic and political persecution during the Cold War.

The Priest Who Put Europe Back Together tells the story of this fascinating life. From solidly middle-class beginnings in Dorchester, Massachusetts, Flynn interacted with and occasionally advised some of the major political, military, and religious leaders of his era. His legacy as a Passionist priest, a chaplain in the US Army, and an official in the Catholic Relief Services was both vast and enormously beneficial. His life and career symbolized the coming of age of the United States as a global superpower, and the corresponding growth of the American Catholic Church as an international institution. Both helped liberate half of Europe from Fascist rule, and then helped to rebuild its political, economic, and social foundations, which led to an unprecedented period of peace and prosperity. His efforts on behalf of both his country and his Church to contain Communist influence, and to assist the refugees of its tyranny, contributed to its collapse. Flynn was one of the hundreds of Americans who put Europe back together after a period of horrendous self-destruction. In a twentieth century filled with villains and despots, Flynn played a heroic and vital role in extraordinary times.
