The publication of Laudato Sí—a papal encyclical on a defining issue of our times-was a moment of great importance for Catholics and for the world. Now Fr. Joshtrom Kureethadam, one of the church's top experts on the document, provides a thoughtful, passionate, and highly accessible commentary on its key ideas and themes. Faithfully attentive to the outline of the six chapters of the encyclical, Fr. Joshtrom has also insightfully arranged the book according to the see-judge-act methodology that is increasingly used in spirituality, moral theology, and the social sciences.
