You didn't have to be a Catholic to enjoy his fine intellect.
His Another Sort of Learning is one of my favorite books.
Fr. Schall was brilliant and faithful, and I think a lot of us will miss him. He was writing dazzling, clear stuff almost until the very end. An amazing person.
A lot of Jesuits were like him. St Ignatius Loyola wanted a corps of brilliant, educated men like him, even though Ignatius himself had been a military man from Pais Vasco and had had to go to Paris and sit with children to learn Latin so he could study for the priesthood.
But the Jesuits have always had a problem with pride, and many recent Jesuits - ranging from Teilhard de Chardin to James Martin to Jorge Bergoglio (a stupid man who got into the order at a low point and says theology makes his head hurt) - seem to believe that they are above the Faith and they know better. And they have done enormous damage to the Church.
