Few encyclicals have been awaited as eagerly as Laudato si’. Pope Francis’s letter is long and complex, as well as fascinating and significant. For that reason, readers will benefit greatly from these essays. Thirteen recognized and respected scholars explore not only the encyclical itself, but situate the document within contexts of liturgy, Catholic social teaching, liberation theology, science, ethics, sociology, peacebuilding, and mysticism. Taken together the essays in this volume provide a wealth of data and information that help us appreciate Laudato si’—its wisdom, its challenge, and its importance for the life of the planet.
