As to the Pope’s assertion that the death penalty should today be rare, I would reaffirm, against Justice Scalia, that this is to be understood as an exercise of the Pope’s prudential judgment. “Prudential” has a technical theological meaning with which Justice Scalia seems not to be familiar. It refers to the application of Catholic doctrine to changing concrete circumstances. Since the Christian revelation tells us nothing about the particulars of contemporary society, the Pope and the bishops have to rely on their personal judgment as qualified spiritual leaders in making practical applications. Their prudential judgment, while it is to be respected, is not a matter of binding Catholic doctrine. To differ from such a judgment, therefore, is not to dissent from Church teaching.
