Catholic Social Teaching

War and Peace

“Peace is not merely the absence of war” (Compendium, no. 494). It is a universal duty, founded on a true understanding of the human person and on justice. The Church calls war a “scourge” and “the failure of all true humanism” (Compendium, no. 497), and she teaches that “a war of aggression is intrinsically immoral” (Compendium, no. 500).

A nation that is attacked has “the right and the duty to organize a defence,” but only under strict conditions (Compendium, no. 500). The Church sets the goal of “general, balanced and controlled disarmament” (Compendium, no. 508) and treats weapons of mass destruction as a particularly serious threat (Compendium, no. 509). Every piece below reads a real conflict against these conditions.

Quotations are from the Compendium of the Social Doctrine of the Church (Pontifical Council for Justice and Peace, 2004), cited by paragraph number.

From The Catholic Citizen

    A machine has no conscience and so bears no moral responsibility, tested against the UN and Red Cross appeal on autonomous weapons. The Catholic Citizen.
