I'm having a hard time dealing with a problem I am having with my mother and I need some guidance.

Here's the dilemma: I've been trying to show my extremly RCC mother where the catholic doctrine contradicts the Bible. And in the process, she figured out that I don't believe the strict catholic doctrine anymore. She won't take anything, even examples directly from the Bible itself, as even remotly possible.

Her reasoning to everything, "2000 years of studying the Bible means we (meaning RCC) can't be wrong." and that, "the devil is trying to persaude me away from the RCC".

She is making life very, very difficult for me, and has forced me to talk to our RCC pastor about how my views (Sola Scriptura) are wrong and misguided. She threatens me about it with lengthy conversation and it's quickly getting to the verge of creating a division between us.

I don't know what to do from here. She has threaten me with another conversation that will only make me (and her) angrier.

I've prayed for guidance and help, but it doesn't seem to be comming as quickly as I'd like it to.

So, in your opinions, What should I do?

(If you could, please link me up with some credible, historical sources that may help me show her that the RCC was never the intended church...)
