Magnifica Humanitas §30

³⁰ Leo XIII ’s Encyclical Rerum Novarum constitutes a milestone in the development of the Church’s social teaching. The document places the dignity of work and of workers at the forefront of its reflection; affirms the right to a fair wage for oneself and one’s family; recognizes that persons have a fundamental value that takes precedence over capital and profit; defends private property along with its indispensable societal role; esteems workers’ associations; and proposes forms of cooperation between the different components of society as an alternative to the mentality of class struggle. It is not surprising, then, that Pius XI defined it as the “ Magna Carta ” of Christian social action. In Rerum Novarum , the Church’s ancient wisdom regarding the human person and life in society took on a new form capable of responding to the industrial age and offering the first major systematic framework for the Social Doctrine that would be further developed in the following decades. While many of the historical conditions described by Leo XIII have changed, at least two insights remain highly relevant today: the primacy of human labor over any mindset focused solely on finance or productivity — with the consequent attention to the people and families most susceptible to exploitation — and the inseparable link between proclaiming the Gospel and pursuing a more just social order. Rerum Novarum thereby continues to remind us that there is no authentic evangelization that does not also affect the structures of human society.
