VATICAN CITY (CNS) -- Entrusting to God's mercy all of their comrades-in-arms who have died serving their countries and defending peace, Pope Francis urged Catholic members of the military to let their faith inform their service. "The world needs you, especially at this dark moment in our history. We need men and women of faith capable of putting weapons at the service of peace and brotherhood," said the papal message to thousands of soldiers, sailors, marines, airmen and cadets making a pilgrimage to the Shrine of Our Lady of Lourdes in France.
