Speeches and texts
- H.E Paul Richard Gallagher Archbishop, Holy See representative to the United Nations, International Day for Elimination of Nuclear Weapons, September 2018.
“The world is not safer with nuclear weapons; it is more dangerous,” Archbishop Gallagher said. “A policy that relies on the possession of nuclear weapons,” he said, “is contradictory to the spirit and purpose of the United Nations because nuclear weapons cannot create for us a stable and secure world, and because peace and international stability cannot be founded on mutually assured destruction or on the threat of total annihilation.”
- H.E Paul Richard Gallagher Archbishop, Holy See representative to the United Nations, on signing of Nuclear Weapon Ban Treaty , September 2017
The Holy See has signed the Treaty on the Prohibition of Nuclear Weapons and has already deposited its ratification, because it believes that it is an important contribution in the overall effort toward complete nuclear non-proliferation and disarmament, an advance toward the fulfilment of the commitment of the States Parties to the NPT “to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament,” and a step toward negotiating a “general and complete disarmament under strict and effective international control.”[24]
Environmental, humanitarian consequences
- H.E. Archbishop Bernardito Auza Permanent Observer of the Holy See to the United Nations, Statement to NPT meeting, April 2015
The very possession of nuclear weapons will continue to come at an enormous financial cost… Pope Francis put it strongly in his message to the President of the Vienna Conference on the humanitarian consequences of nuclear weapons: “Spending on nuclear weapons squanders the wealth of nations. To prioritize such spending is a mistake and a misallocation of resources which would be far better invested in the areas of integral human development, education, health and the fight against extreme poverty. When these resources are squandered, the poor and the weak living on the margins of society pay the price.”
- Pope Francis message to the Vienna Conference on Humanitarian Impact of Nuclear Weapons, December 2014
” Nuclear deterrence and the threat of mutually assured destruction cannot be the basis for an ethics of fraternity and peaceful coexistence among peoples and states. The youth of today and tomorrow deserve far more…Spending on nuclear weapons squanders the wealth of nations.
