I don't know the Cardinal and have read only one of his books and a couple of articles, but I appreciated him from what little I sampled. I thought this quote from Cardinal O'Malley's blog shows that Cardinal Dulles understood the Lord and set a good example for the rest of us:
Suffering and diminishment are not the greatest of evils, but are normal ingredients in life, especially in old age. They are to be accepted as elements of a full human existence,” he said. “As I become increasingly paralyzed and unable to speak, I can identify with the many paralytics and mute persons in the Gospels, grateful for the loving and skillful care I receive and for the hope of everlasting life in Christ. If the Lord now calls me to a period of weakness, I know well that his power can be made perfect in infirmity. Blessed be the name of the Lord!May he rest in peace.
