Magnifica Humanitas §29

²⁹ What we now call the “Social Doctrine of the Church” is not a spontaneous product of the modern age. Instead, it is the fruit of receiving and structuring a long tradition of ecclesial reflection on life in society, rooted in Sacred Scripture, the Church Fathers and the theological and legal developments of the Middle Ages and modern era. Although the expression “Social Doctrine of the Church” was coined by Pius XII in 1950, its content began to take shape as an organic corpus of social teaching with Leo XIII’s Encyclical Rerum Novarum . Confronted with the “new things” of his time — the conflict between capital and labor, the question of the workforce, and economic and social transformations — Leo XIII did not limit himself merely to acknowledging the unrest, but saw these situations as an area for the Church’s pastoral mission. He exposed them to rigorous discernment, illuminating their causes and possible solutions in the light of the Gospel and an integral vision of the human person created in the image of God. Saint John Paul II regarded this approach as a “lasting paradigm” of Social Doctrine: an exemplary practice through which the Church, when faced with historical changes, exercises her right and duty to examine social realities, make pronouncements about them and indicate paths for finding just solutions. In this way, the perennial contents of the faith and ancient ecclesial wisdom find expression in a living doctrine that remains faithful to the Gospel while growing in response to the “new things” of every era.
