I have a good friend that is very in tune with her religion. She reads her bible all the time.

She goes to church everytime the doors open. However sometimes she really gets on my nerves. If I am upset with my kids or something, she will start quoiting scripture. Now she has a friend on Facebook that has started putting things about her religion and my friend does not agree with it. She tells me everyday that she has put this or that on her posts, and it really makes me angry. I was wondering what I should do? I just try to keep my mouth shut and not comment on how my friend is being very ugly. She tells me yesterday that the girl posted something and she could not handle it, so she called her Sunday School Teacher and asked her what she should say to her. I was completely beside myself. What do I do? How can I tell her that I do not want to hear about it without hurting her feelings?
