Note:
Cardinal Dulles says theologians must pray. It would seem like a ‘no brainer,’ but I’d bet he knew of some theologians who said they didn’t. Or maybe it was his way of saying that theologians can’t only be book-learning head-knowledge people.

Quote:
“So the theologian must participate in the prayer life of the church and be a praying person himself or herself in order to think the thoughts of God, as we theologians try to do. A theologian who does not pray could hardly be a good theologian.” [emphasis added]
