The Bloody Question, so I recall, was put when Elizabeth Tudor's interrogators asked: "If a papist army invaded this realm, would you fight for the Queen or the invaders?". Bloody, because unanswerable: "the Queen" means you would be fighting against coreligionists; "the invaders" means you are a self-confessed traitor.
People who have trouble accepting the women-priests dogma and who seek communion with the Holy See tend to get asked: "But what will you do if Rome herself changes her mind?" If the answer is "I will follow Rome", then the come-back is available that "If you're happy enough to change your mind when Rome changes, why are you making such a fuss? Why not wait and see if Rome does change?" Alternatives, such as "I'll join the Orthodox*" mean that one is confessing to being Protestantissimus; one is not accepting the Church's Magisterium, but testing the Church by one's own Magisterium. The assertion "Rome won't change" gets one into a scrappy argument when 'examples' are adduced of changes which, it is claimed, have occurred in Catholic teaching over the millennia.
Politicians have more sense that to get into discussions with journalists about possible contingencies. They are wise. Since contingencies, some probable, others improbable, are literally, logically endless, following the interviewer down this path means that, sooner or later, he will succeed in making a fool of you.
What I think one can do is to throw oneself into the contingency game as a willing player, rather than leaving the richly dangerous quagmire of Contingency-land in the exclusive possession of the enemy.
Example will follow.
*Do I recollect that one of the politicians who converted to Rome back in the 1990s once, in the early days, said something like this? If not, I apologise to all of them.
