Should I stop praying the Rosary?

NOOOO!.... anyway, I'm not catholic and a lot of non-catholics have the misconception that you guys aren't "real" christians. I think that's crazy since catholics were the first christians. I had to educate my whole Sunday school class on this very same topic last week (we're non-denominational). whoever told you that you were going to hell was jus misinformed, so ignore him/her. Just because you pray differently does not mean you're going to hell.
