The Venerable Pope Pius XII was one of the recognized leaders of the Roman Catholic Church who took charge at a time when the world was embroiled in a long, tumultuous and conflicting phase of World War II. His reign, which is the most controversial one in regards to the modern times, was marked by dealing with the ravages of World War II, facing the abuses of the Nazi, Soviet and Facist regime, confronting the challenges of post war period and above all, rising above them and balancing the spiritual and religious dogmas in tough times. Though criticized for his ‘public silence’, his ‘neutrality’ and his ‘inaction for the fate of Jews’, Pope Pius XII who had been a diplomat all through his life before becoming a pontiff, used the same to aid the victims of the war. In his diplomatic ways, he lobbied for peace and spoke out against the ill-fated death of innocents but not so strongly so as to offend the Nazi and further ignite the combat. Post war, he strongly advocated peace and reconciliation. Pope Pius XII was also an ardent opponent of Communism and came up with a doctrine that in effect could excommunicate Catholics who professed communism.
