Let’s imagine there are two fellows.
Person 1 has strong faith, firmly believes that salvation is purely through the grace of God, and the death of Jesus has saved him from eternal damnation. Yet, he suffers from a certain weakness of disposition/flesh, and so never really goes to Mass, can’t stop his life of sin (let’s say, fornication), and doesn’t have the strength of character to be a ‘good Christian’ in practice (but he’d like to be). Perhaps, he thinks after all, it is not his merits, but Christ’s, which win him Heaven.
Person 2, for various reasons (unanswered prayers, bad experiences with the Church), has concluded (with maybe 75% assurance) in his heart that we live in a universe governed by chance, and after death we are reduced to dust. Nevertheless, he is an exemplary ‘good Catholic’ (perhaps a married man, or even a priest), and continues to live as a ‘good Catholic’, practising religion and charity and observing moral rules without fail. His motivation might be a kind of stoicism, or concern for his family and others, or the view that, even if nothing matters, a life lived as a good Catholic is better than any other (and there’s a remote possibility that there is actually Heaven and Hell). So he is faithful, charitable, moral, etc., until the very end. He encourages others in their faith, not because he believes it’s really true, but because it seems like an influence for living as a decent, and relatively happy, person…
Who has the best chance for salvation of these two chaps?
