But to allow someone to enter the Church and willfully to disagree with her clearly taught magisterial doctrines, morality, and dogma, that’s a major fail.
I think they can. It’s entirely possible for someone to say
“the Church teaches X, but I just can’t wrap my head around it — just according to my own lights, I think the Church is wrong, I’d agree if I could, but I just can’t”. At that point, they make a choice either to accept it on faith and disregard their own thinking, or to reject it. The voluntariness, then, is in refusing to prefer the authority of the magisterium over their own thinking. I myself have some difficulties accepting a few of the Church’s teachings (it’s pretty arcane, not the stuff you normally would think of), but I just take it on faith and squash my own misgivings. I realize that people far wiser than I, throughout the past 2000 years, have “seen it the Church’s way”, and thus I resolve to do so as well.
Second, it’s absolutist statements like this, (“believe it, or else!”), that do, indeed, cause me to question whether or not I should remain Catholic.
I’m sorry to know that, but that’s just the way it is in Catholicism. When a doctrine, dogma, or moral teaching is clearly set forth and enjoys the ordinary infallibility of the magisterium, it’s pretty much “case closed”. There can be such a thing as development of doctrine or a deeper understanding over time, as we have seen throughout Church history (religious liberty,
extra ecclesiam nulla salus, etc.). But we can’t just pick and choose, whether voluntarily or involuntarily.
If someone sincerely disagrees with something the Church teaches, I think they are entirely within their rights to go to the magisterium (Congregation for the Doctrine of the Faith
et al), state their misgivings, be able to back up what they see as the truth of the matter, and ask the Church for clarification. I would have had absolutely no problem with Luther nailing his 95 theses — what happened afterwards was where things got sticky (to say the least).
