And whatever his intentions, the phone call and the coverage of it suggest two obvious perils for a papacy that leans too heavily on the distinction between the doctrinal and the pastoral, between official teaching and its applications.

One is what you might call the late-Soviet scenario, in which Catholic doctrine is officially unaltered, but the impression grows that even the pope doesn’t really believe these things, and that when the church’s leaders affirm a controversial position they’re going through the ideological motions — like Brezhnev-era apparatchiks — and not actually trying to teach a living faith.

The other is the dashed-expectations scenario, in which the assumption that a church teaching is about to change creates widespread disaffection when it doesn’t. This happened with contraception in the 1960s, and it could easily happen with divorce and remarriage under Francis…

There is also a third perilous scenario, even if my own assumptions about the nature of the church tend to rule it out. Francis could actually be considering a truly major shift on remarriage and communion, in which the annulment requirement is dispensed with and (perhaps) a temporary penance is substituted.
