One of the best books I ever read (long before I ever decided to go to Gradual School I might add) was The Assurance of Things Hoped For., By Avery Cardinal Dulles SJ It was the most amazingly clear (but very deep) study of faith I had ever read. I was hooked from that point.
I loved the way Cardinal Dulles could explain the most complex of issues (although I will freely admit that there were times that I had to read certain passages two and even three times to be sure I was comprehending exactly what he was saying).
When I did reach Gradual school I had a professor there who had studied under "Fr. Dulles" at Catholic U in DC. We were treated to many very funny and captivating stories about him.
So I was saddened to hear that he had died this week.
His faith and service to the Church will be greatly rewarded in heaven.
