Professor Echeverria does a thorough job of drawing from the pre-papal writings of Jorge Mario Bergoglio and the man’s current papal writings, talks, and sermons (notably Amoris Laetitia, Laudato Si’, The Name of God is Mercy, Veritatis Gaudium, and through Christus Vivit) to discover and document the continuity in thought Francis has with the councils. Echeverria compares Francis’s discourse with that of his papal predecessors (John Paul II, Bendict XIV, and Paul VI) in the era since Vatican II. He draws heavily on the documents of Vatican II and the theology of doctrinal development stemming from the First Vatican Council and embraced by Vatican II, e.g. Leo XIII and Pius XI. Not left out is the modern ecumenical movement from both the Reformed (Berkouwer et al) and Catholic (Rahner, Balthassar, Mauritain, Kasper, et al) side. This is Echeverria’s second edition, revising (with new insight from Francis’s voluminous writings through April of 2019) and expanding (almost twice the size) the best-selling book introduced four years previously.
