Chez Filippini and Dr. Luke Arredondo continue their Catholic Social Teaching series by discussing Pope Pius XI's 1931 encyclical "Quadragesimo Anno", a follow-up to Pope Leo XIII's "Rerum Novarum". They explore the document's key themes, including subsidiarity, labor relations, wages, and critiques of both capitalism and socialism. The encyclical emphasizes the need for a moral approach to economic life, condemns the excesses of individualist capitalism and socialist ideologies, and calls for a return to gospel principles.
