I will be honest with you. I believe that the Church is true through my own human experience with life and with people. I will be honest with you when I say, “I chose to believe the Bible is true.” It makes sense to me. I have faith that it is true.
The bible is not a document from which I would recommend you develop a sound moral outlook, unless you want to cherry pick the living daylights out of it (which I presume that you must do). Take out all the historical padding, the begotten and begats, the Sunday School stories of talking donkeys and prophet swallowing whales, the massacres and plainly nonsensical commandments about capital punishment for stick collecting and you’d have not much more than a thin pamphlet suggesting that the Golden Rule appears to be a good idea.
So to answer your question: what would I do if my reason convinced me that the Church was wrong on something?
First, I would ask the opinion of individuals around much as my pastor regarding the issue.
Second, I would consult the writings of the saints, and see what rational arguments they would have to offer on the matter.
There is plenty that the church teaches that makes a reasonable amount of sense in most situations, but the situation with almost all questions of morality is that there are simply no black and white answers.
I’m sure that you’d be able to find something that might give you a heads-up on whether torture is acceptable or not. But then we have a problem as to the definition of torture and the degree to which is might be carried out. And the circumstances in which it may, or may not, be done. So what conclusion are you going to draw from Catholicism in this matter?
There is no correct answer that covers all contingencies. Yes, we can all reach agreement on what would be too much (maybe tormenting someone for all of eternity perhaps). And I’m sure that we could all agree on what is so benign as to not be considered torture (maybe no ketchup on their fries) but that doesn’t mean that there is an objective answer to the question. It entirely depends on what we personally consider to be too much or too little. So there’s not going to be much help forthcoming from your pastor, anything the saints might have written, scripture, theologians, the catechism or any other source. Your pastor might give you HIS personal opinion but that’s as far as it goes.
So what do you personally do? Well, you do exactly the same as I do. You take all the available evidence and listen to arguments from both sides and then make a personal decision. Yeah, sure, you can ask God directly if you like but it’s kinda strange when He gives you a different answer to someone else who is also asking for guidance.
So (horror of horrors), I make up my own mind about a lot of matters. Exactly as you do. Except that there may be one subtle difference: I go to all available sources, not just the ones that might back up my own preconceptions. It’s the reason I don’t post on atheist forums but on Christian ones. It’s the reason I buy books by Trent Horn (the last just two days ago) as well as ones by Sam Harris. What on earth is the point of discussing and reading about important matters of morality with people who are likely to agree with anything you say? You need an opposing view. You need your preconceptions (and we all have them) put to the test. You need a Devil’s Advocate.
I keep getting asked, time and time again, how as an atheist I can possibly come up with the correct answers to moral questions when I have no ultimate authority to whom I can defer. Well, you have what you consider to be the ultimate divine authority which gives your moral decisions some type of superiority over any decisions that I might make… So with that in mind, how about you give us your definition of torture and what you consider to be acceptable.
And then you can tell me how you reached this quite personal decision. Because as sure as your God made little green apples, you won’t get the answer from your local priest, church teachings, Aquinas, the catechism or reading the entrails of goats.
