just so i get this straight: is possibility that the church infallibly decreed gecentrism and geostaticism being considered on this thread based on what was said by a pope and a few cardinals in a papal condemnation?
whatever else might be uncertain, a document of that nature is certainly neither authoritative nor binding on the magisterium or the faithful.
and whether or not scriptural interpretation is subject to the rule of “only faith or morals”, papal decrees certainly are, and any promulgation by a pope concerning astronomy is outside the purview of his authority and thus of no force and effect, regardless of the particular form in which it is expressed (be it a constitution, bull, encyclical, brief, or letter).
what’s more, bulls can be revoked by the holy see; but if that’s true, they cannot be infallible, since a proposition once declared infallibly to be true cannot later be declared to be false. unless, of course, the proposition is temporally indexed (e.g. “john likes to eat cornflakes for breakfast at this point in his life”) and sibject to change. propositions about the absolute motions of the earth and sun through the heavens, though, are clearly not of that nature - that is, unless we consider it possible that the earth was once stationary and only lately has begun to move, then it simply makes no sense to suppose that an infallible proclamation by the magisterium and the bishop of rome concerning the earth’s absolute rest could later be reversed.
in other words, the very possibility that rome could declare, contra any previous declarations to the contrary, that the earth moves around the sun, entails that none of those previous promulgations were (meant to be) infallible.
