The Church of God
The author, himself a former Lutheran minister, also explores Reformation views of the Church, as well as the Catholic Church's deepened understanding of her distinctive identity and her imperfect but real communion with the Orthodox churches and Protestant ecclesial communities. The Church of God is a major contribution to the ecclesiology of communion fostered by the Second Vatican Council and continued by Pope Paul VI, but especially by John Paul II and Benedict XVI. Indeed, the book reflects the "hermeneutic of reform" Pope Benedict XVI insists should guide the interpretation of Vatican II.
