Should Catholics Run (Away) From Secular Politics? | Fr. John Harris, O.P.

St. Thomas Aquinas' Letter to Prince Charles I of Anjou offers practical advice on political governance, focusing on justice and the common good. Unlike the broader philosophical scope of De Regno, this letter provides more specific guidance. Aquinas emphasizes the importance of moral virtues like justice, prudence, and charity in ruling. He warns against tyranny and selfish governance, stressing the ruler's role as a servant of the common good. The letter highlights Aquinas' consistent concern for harmonizing temporal and spiritual ends in political life.

De Regno, or 'On Kingship,' by St. Thomas Aquinas, is a treatise on political philosophy and kingship. It offers guidance to rulers on governing justly and achieving the common good, blending Aristotelian political thought with Christian theology. Aquinas emphasizes the ruler's responsibility to promote both the temporal and spiritual well-being of their subjects, balancing material prosperity with spiritual growth. The work explores the relationship between earthly authority and divine providence, highlighting the importance of natural and divine law in governance. It remains a significant text in the history of political philosophy and Catholic social teaching.

Pope John Paul II's encyclical "Centesimus Annus" reflects on the 100th anniversary of Pope Leo XIII's Rerum Novarum. It addresses the social and economic challenges of the late 20th century, particularly the fall of communism and the rise of globalization. The encyclical affirms the importance of a market economy while emphasizing the need for ethical and social considerations. It critiques both unrestrained capitalism and collectivist systems, advocating for a model that respects human dignity and promotes the common good. John Paul II stresses the importance of solidarity, subsidiarity, and the role of the state in ensuring social justice. The encyclical remains a significant contribution to Catholic social teaching, offering guidance for navigating the complexities of modern economic systems.

St. Thomas Aquinas's Summa Theologiae is a monumental work of systematic theology, aiming to present a comprehensive overview of Christian doctrine. It's structured around questions and articles, exploring various aspects of faith and reason. The Summa covers topics such as God, creation, the human person, salvation, and the sacraments. It's considered a cornerstone of Catholic theology and has profoundly influenced philosophical and theological discourse for centuries. Its enduring relevance lies in its systematic approach and integration of faith and reason.
