As reported over at Faith and Theology, Roman Catholic theologian Avery Cardinal Dulles [pronounced “Dull-us”, I believe] has passed away at age 90. I have used and refer to Dulles’ book, Models of the Church often in my own ecclesiology classes. His method of using “models” helps to give a broad picture to differing ways of viewing the Church. I also enjoyed his Models of Revelation. The New York Times obituary can be found here. Avery Dulles was the son of John Foster Dulles, the secretary of state under President Dwight D. Eisenhower.
