Encyclicals are letters promulgated by the Pope, circulated to the Catholic faithful and to “people of good will.” These letters are written in response to the realities in today’s world, especially in the areas of faith and morals.
Writing these encyclicals is an exercise of the pope’s teaching office. Encyclicals explore these issues in light of the Christian faith, with the aim to inform human reason. The way in which we live and structure societies raises moral questions.
Social encyclicals, including Pope Francis’ world-changing Laudato Si’, are a type of encyclical that explores moral questions. They look at justice in society, engaging the situation based on truths provided by human reason and revealed by the Christian faith.
The aim is to maintain that life in society fulfills the requirements of justice, fostering true freedom and affirming human dignity. Social encyclicals provide a roadmap for Catholics and people of good will to discern together the course of societal living. Below are the social encyclicals that make up the body of teaching called Catholic Social Teaching:
