Book excerpt: Given the Catholic Church’s complex history concerning divorce and remarriage, it’s not surprising that the promulgation of Amoris Laetitia in 2016 caused such a stir among the laity, the press, some theologians, and even some bishops. This book endeavors to introduce concepts and contexts for understanding the document in a new light, explain what the rule of law actually means, and hopefully open a door to further discussion among theologians and clergy whose critical comments have so often missed the point of Francis’s apostolic exhortation.
