So how many Catholics have been condemned to hell because they followed a 'pious opinion' and relied on Mary to redeem them instead of Christ? It's an extremely dangerous opinion when your salvation depends on knowing the truth. We might not see it much in the US but there are numerous places in the world where Mary is worshiped instead of Christ.

“In a time of deceit telling the truth is a revolutionary act.”
― George Orwell
