Again, that doesn’t make sense. If it isn’t clearly so, then it might as well not be? Why not: if it isn’t clearly not so, then it might as well be?
Because if it’s not infallible then it could be wrong. The whole purpose of infallible declarations, as far as I can see (and maybe others have a different perspective) is to provide absolute certainty about a particular teaching, so that people in the Church know where the are to stand. If it isn’t clear that a particular statement is infallible, then we certainly don’t have the absolute certainty purposed by such teachings.
It strikes me and my spiritual sensibilities (yes, UAR) as being something of a matter of common sense for any true son or daughter of the Church. Why would one deny this, except in an attempt to preserve his own false liberty of conscience over against the teaching of the Church? (Maybe there are other reasons, but I’d wager that’s the most common one.)
No reasonable person would. That’s why any Catholic under the authority of the Bishop of Rome should submit to the teaching on contraception, even if he or she thinks that teaching might change. Even if the teaching is disciplinary, or worse, even if the teaching is wrong, obedience to God’s appointed supreme head of the Church and Vicar of Christ is a great virtue, and rejecting God’s appointed is a great vice.
For a Catholic UAR this argument is mostly intellectual because even if it proves its point, it still shouldn’t change the way a Catholic UAR would teach or live, until the Pope and Bishops would change their teaching. If true, it would do two things. First, in the rare instances where charity rules the law, it would encourage Catholics UAR to consider the use of contraception, and would assuage their guilt. Second, it may give intellectual teeth to the arguments of the majority of lay Catholics nominally UAR who want this teaching changed, and may allow a door for them to return to the authority of Rome.
For a Catholic NUAR, the argument is purely intellectual (save for the charitable desire to help those who are discouraged by Catholic teaching, and want to see a way it might change in the future). After all, if I don’t accept the Pope’s absolute authority (though I do respect his primacy, and as such read everything I can that he’s written, especially the encyclicals and pronouncements, and try to accept them where I find it reasonably possible), I need not go through any arguments about what’s “ex cathedra” and what’s not. I might as well assert simply that the Pope made a mistake, and if he made a mistake with an ex cathedra pronouncement on faith and morals, so much the worse for the doctrine on ex cathedra pronouncements.
If if the teaching weren’t infallible, it would still be absolutely binding for Catholics UAR.
True. Except, of course, where charity may trump the law.
Just as abstaining from meat on Fridays was at one time absolutely binding for Catholics UAR, and still many dietary disciplines are binding for Byzantine Catholics, these rules, being discipline, being not certain or moral or de fide, may be suspended for the sake of charity. For example, it would have been good, even when it was against established discipline, to eat meat on a Friday if your mother made it for you and would be very disappointed if you didn’t eat with the rest of the family. This sort of suspension of non-absolute or uncertain rules for the sake of charity has been well in use since the time of the early Church Fathers.
