When Bishop Robert Barron and Cardinal Müller sat down to talk for over an hour together a few days back, it was always going to be a matter of intellectual interest. There is a danger that when clever people start talking they are tempted to want to show off and dazzle their audience with their learning, but this was one of those very rare meetings where both men had the capacity to gear their intelligence to the need of the moment and allow it to come out as wisdom, offering an antidote to the existential crisis faced by Church and culture.
