The question I responded to was why they say that they can safely stay in the Novus Ordo.
Every person I've met that truly fits your description has reservations. They don't unequivocally say that the Novus Ordo is safe even as they have difficulty figuring out the alternative. Those who do are simply not Catholic.
They think they're Catholic. The "confusion" began almost 60 years ago. Hard to believe it's been that long already. I remember when it all began as if it were yesterday. Only the grace of God could have sustained me or anyone else through it, only to come out the other side of it with any semblance of Catholicism still intact. I attribute that in part to the Dominican Sisters (long since defunct) who taught me, as well as the grammar school (boarded up due to lack of students after having once boasted of 1,600 in the school in 1965) I attended.
What I'm saying is that, at this point, unless they make an effort to find out otherwise, as far as they are concerned, they're Catholic.
By the way, do you happen to know the definitive Church teaching on ѕυιcιdєs pre-VII? I'm still waiting for someone to answer me on that. :)
