The chatter goes on as to whether Benedict will change this or that "policy" of John Paul, as though each new pope reinvents Catholicism. There is, beyond doubt, development in the life of the Church, but on questions of great theological and moral moment there is not change. The office of the papacy is very limited. The pope's job is to defend, preserve, and transmit the "faith once delivered to the saints," as that faith is received in Scripture and Spirit-guided tradition. A pope who acts as though doctrine is no more than a policy option is a very bad pope.
Here is the whole thing.
