I’d be interested in hearing the opinion of those who follow the internal affairs of the Catholic Church closely as to how likely they think it is that the Church will in the foreseeable future (or ever) permit the ordination of women. More and more Protestant denominations have been doing so, but my guess for the Catholic Church would be “not very likely”.
It will never happen. John Paul II, Benedict XVI, and now Francis have all infallibly taught the ordination of women is an impossibility.
Theoretically, though, there is nothing to stop a future pope from overruling all of those ones and declaring infallibly that women can be priests, right, despite this being very unlikely to happen?
It is theoretically possible if you take the position that the previous statement was not infallible, but even that would be some level of rejection of the teaching authority of the previous Popes. While technically only
ex cathedra statements absolutely cannot be contradicted, the teaching authority of the Pope is considered authoritative on a wider basis. It would be very extreme, basically unthinkable, to overturn point blank statements like JPII's condemnation of women priests, especially while they are in living memory.
One of the more common misconceptions of Papal infallibility is to see it as a power of the Pope when it is really a limit on Papal power, since it also means his predecessors were infallible too.
