The other day Abp. Felix Machado said that Balthasar was a powerful name these days; almost all the big positions in the Vatican were being held by Balthasar people, and to study Balthasar, to be an expert in Balthasar, is to have a shortcut to the Vatican.
John Misquitta, SJ, said that Balthasar seems to be used as a stick to beat Rahner with; there has been, over the last few years, a concerted effort to discredit Rahner.
In fact, Balthasar is a big name even at the Gregorian these days; Rahner is hardly spoken of.
Of course, I think the names of Balthasar and Ratzinger were never even uttered in our theology days here in India... For some reason, these two names are not beloved on the Indian subcontinent, unless things are changing now.
But there was / is also a Blondel influence on the Gregorian. In my time there (1990-94) there used to be Peter Henrici, world-renowned Blondel scholar, as well as Xavier Tilliette, who is also in his own right a Blondel scholar, besides some others too. Henrici is a nephew of Balthasar's from his mother's side, and I think I remember him saying that Balthasar was influenced by Blondel.
So Blondel, Marechal, Balthasar, and so on: would be interesting to study those connections.
Bob Doran is of course trying to bring Lonergan and Balthasar people together; he himself and some of his students seem to be writing stuff on Balthasar. Fred Lawrence does not seem to be that keen on this particular connection. I think he feels Balthasar remains somehow too much locked up in the metaphorical, the figurative, the descriptive.
