Actually, it would just be alright if Catholics would just come out with it and say something like, “Okay, we do believe that no person can be saved and go to heaven without going through Mary, so you non-Catholics need to repent and appeal to Mary for salvation (among other Catholic church requirement). If you don’t you can only expect to spend eternity in Hell.”
Why would Catholics "come out and say" something so demonstrably non-Catholic?
Anyone who believes that quote represents what Catholics secretly believed should seek professional help.
And we would be overjoyed if you would simply stop trying to tell us what we believe.
