I find it extremely interesting that both Heidegger and Lonergan seem to have been set on the path of thinking by a similar, if not the same, problem: the relationship between faith, scripture and doctrine.
Heidegger was searching for a new and adequate language for the christian faith. He did not find it, and thought intellectual honesty demanded that he depart from the faith. Ever the enigma, of course, he asked for a Catholic funeral service.
Lonergan put it this way: "All my work has been introducing history into Catholic theology." Crowe has an article on this topic, and just today I read Lonergan talking about "the as yet unfinished task" of effecting the synthesis of historical and theological aims "so that we have neither history without theology nor theology without history, but both." ("Theology and Man's Future," A Second Collection, 1974, 136.)
One of the factors in this divergence needing further exploration is the role of Scotus: Heidegger did his second thesis on Scotus.
