Abstract

At the forefront of almost all governmental and ecclesiastical policies on peace and war is the question of what to do about nuclear weapons. While this question remains unresolved in the world today, New Zealand's response in the 1980s has recently gained traction again as the new Nuclear Weapon Ban Treaty was passed in July 2017. New Zealand proposed its answer in 1987 when it enacted its 'Nuclear Free Zone, Disarmament and Arms Control Act'. The impetus for that legislation was the popular support for Prime Minister David Lange's Oxford Union address in 1985. Lange's speech moved the nation's position beyond the political sphere into social, ethical and religious circles. This paper revisits that speech and the rationale behind New Zealand's decision in light of fundamental Catholic moral theology. It highlights common moral ideals between the New Zealand Catholic Church and government, points of agreement between the Catholic Church's moral teaching and New Zealand's nuclear-free policy, from the time of New Zealand's nuclear-free movement as early as the late 1950s, through David Lange's Oxford Union address, and the government's enactment of its nuclear-free legislation in 1987, up until today. Specifically, it seeks to exhibit how the logic of Prime Minister Lange's position corresponds to Catholic moral thought, evidencing an example of political - religious unity and a common church - state purpose for those people who are interested in moral, social, and political - religious cohesion. No critical analysis of arguments for and against nuclear weapons is intended, but rather simply the evidence of a positive co-relation between New Zealand's government and the Catholic Church on the nature and potential use of nuclear weapons.
