It is a long tradition to pray for the dead on the 3rd day after death, 30th day and 1st year.
Say a prayer for the late Avery Card. Dulles, who died one year ago today.
Good… now that you have said a couple prayers for him, go read something he wrote.
You might start with an article he wrote for First Things.
Toward the end of his life, Card. Dulles wrote some great stuff for First Things.
One of his earlier pieces in that esteemed journal, one of my favorites, was his devastating assessment of the Lutheran-Catholic Joint Declaration. He points out that pesky problem of the doctrine of the Council of Trent.
Anyway… here are some other links, thanks to the Ratzinger Fan Club.
