This has been reported widely, but it is important to note it at least here, since Cardinal Dulles was a champion of serious theology, and he was a serious reader of St. Thomas. See the following:

• A Newsweek magazine appreciation by George Weigel
• The Fordham University page for Cardinal Dulles
• From the Times in London
• The article about him on Wikipedia

He was scheduled to speak a few years back at the Ave Maria conference on the sacraments, but his ill health prevented him from coming—so he read his paper as he was video-recorded, which in turn was played to the conference on a DVD! One comment in the paper—”…what God is willing to accept from us…”—stays with me to this day.
