So you do think it's a good idea to withold the truth of the gravity of their situations?
People who are cheating on their spouses, or embezzling money, or beating their wives know they're doing wrong. I try to get them to see what they're doing to themselves RIGHT NOW, as human beings.
That usually works.
I meant not telling the truth to couples who were co-habitating (a mortal sin)? Do you think it's a good idea that they not be aware that it's a mortal sin, and that they will go to hell if they don't repent and turn away from it? Or do you think it better to withold this truth from them, and give the impression that the Catholic Church condones such behavior?
