I would agree with those who have said "who can say? ". I have a question though about your scenario of the adult Catholic… if they know what the CC teaches about the Church, mortal sin and other faith matters, but do not follow the teachings because they are not convinced, is their salvation in serious jeopardy according to Catholics and the Church?
It’s a touchy question, without a doubt, and one which we can’t give a definitive answer, in a certain sense (after all, only God can judge, right)? Yet, in terms of speaking in the abstract, it would come down to what the person
knew – in other words, it depends on catechesis – and how the person approaches the faith. For instance, a person who was not well catechized would be leaving a Church that he doesn’t fully understand. (The question here, of course, would be the level of culpability.)
The question you ask, I think, speaks to a person who
is reasonably well catechized, doesn’t it? In that case, there’s a different dynamic in play. A Catholic who knows his faith well, has been taught that (and, putatively, knows that) in the Catholic Church there is the fullness of the truth – that is, he has been taught not only ‘stuff’ (i.e., the tenets of the faith), but also, the grounds for that stuff (i.e., why the Church teaches what she does). He’s been taught that Christ created His Church and set the Apostles at its head, to lead her and teach in His name; he’s been taught that the doctrinal teaching of the Church is protected from error by the Holy Spirit; he’s been taught that doctrine develops over time, as the Church understands God’s Revelation more fully and expounds on it in language accessible by each generation. Now… the question is this: what is it that such a person has rejected? What is it that the person remains ‘unconvinced’ about? If it’s simply the ‘stuff’, then that’s not surprising – many Catholics continue to struggle with and learn more about the ‘stuff’ that the Church teaches. However, that’s not a reason to leave the Church. On the other hand, if it’s that he rejects that God is teaching the Truth through the Church, then that’s another matter altogether. In this case, the person’s act of leaving the Church doesn’t only say “I’m working through my understanding of this doctrine” but rather “I don’t believe that the Church is capable of teaching the truth.”
That statement – made with one’s feet! – is one that we would say leaves the person (who was in possession of the fullness of the truth but has decided to walk away from it) in jeopardy.
Does that make sense?
In re-reading some posts I guess John Martin might have been touching on this in his post referencing about conscience and walking away.
I haven’t seen these posts. The Church teaches that we all must obey our consciences. However, she also teaches that we are obligated to form our consciences properly. That is to say, when our conscience says “I must do
X”, we must say, “Hmm… but the Church teaches that we cannot do
X. Why is it that my conscience is telling me to do something contrary to the Church’s teaching? I’ve gotta find out where the discrepancy is … and fix it!” Many take the first step (“I’ve got to follow my conscience!”) without bothering to attempt the second!
