Absoultely not, as I wrote in the very post you quoted, don't need religion to make the right choices.
You can live your whole life as a good catholic, without ever knowing it or anything about the religion.
I'm a believer and knowingly made bad choices, doesn't put me in front of the que, it's how you live your life that counts.
Sorry I see it now.
With what you said about not even needing to believe to get in. One of the very few things I remember from years at catholic school was the religion teacher saying you need to believe to get in.
