The Church of England passed the following motion in July 2018 at General Synod in York:

That this Synod, mindful that a faithful commemoration of the centenary of the 1918 Armistice must commit the Church afresh to peace building; and conscious that nuclear weapons, through their indiscriminate and destructive potential, present a distinct category of weaponry that requires Christians to work tirelessly for their elimination across the world:

(a) welcome the 2017 UN Treaty on the Prohibition of Nuclear Weapons and the clear signal it sends by a majority of UN Member States that nuclear weapons are both dangerous and unnecessary;
(b) call on Her Majesty’s Government to respond positively to the UN Treaty on the Prohibition of Nuclear Weapons by reiterating publicly its obligations under Article VI of the Nuclear Non-Proliferation Treaty and its strategy for meeting them; and
(c) commit the Church of England to work with its Anglican Communion and ecumenical partners in addressing the regional and international security concerns which drive nations to possess and seek nuclear weapons and to work towards achieving a genuine peace through their elimination.

Pope Francis: “There is an urgent need to work for a world free of nuclear weapons in full application of the Non-Proliferation Treaty, in letter and in spirit, with the goal of a complete prohibition of these weapons.” (25 September 2015)

Baptist, Methodist and United Reformed Church leaders: “Our churches urge the British Government to work tirelessly to rid the world of weapons of mass destruction … Replacing Trident would send the wrong message to aspiring nuclear powers. … Replacing Trident with a new system with a potential lifespan to 2050 flies in the face of commitments that the UK has made under the Non-Proliferation Treaty.”

In Wales, all the bishops of the Church in Wales, all the Welsh RC bishops, the leaders of the Presbyterian Church of Wales, the Baptist Church, the Methodist Church, the United Reformed Church, the Union of Welsh Independent Churches and the Religious Society of Friends: “We believe the proposal to spend £25bn on replacement of the Trident system is a denial of out Treaty obligations and an encouragement to more non-nuclear states to develop their own weapons.”

The Moderator of the Church of Scotland and Cardinal Keith O’Brien’s joint statement to the 2007 Non-Proliferation Treaty Meeting: “This planned renewal of Trident is contrary to international law and opposed by the majority of people in Scotland –is contrary to the objectives of the NPT –is contrary to the teachings of all the world’s faiths. We are deeply concerned.”
