Pope Francis, Jeremiah Barker argues, shares the theological, ethical, and spiritual core of John Paul II and Benedict XVI's social teaching. Barker reappropriates R.R. Reno's call for theologians to apply themselves to the elements of a cogent argument in Francis' work, and draws out the underlying rationale of Francis' message, which he argues is the same as the two previous popes. Inspired by Francis' call and teaching, Barker's compelling argument is an opportunity to reconsider the legacies of John Paul II and Benedict XVI in the light of contemporary Catholic debates and challenges. A unique and refreshing analysis, Barker's argument is relevant for any Catholic seeking to make sense of these popes' messages.
