So freshman year of high school I became frienda with a girl who I would have never thought would be my friend. Now in my sophemore year, I have gotten to know the girl better. She is not a Catholic like I am, she is a Christian, and I respect that. But lately she has been insulting my faith. She invited me to her house but I told her I had to attend Catechism and I couldn’t miss it. She then asked me, “What is catechism?” I answered her question and then she replied with, " That is so stupid!" I felt crestfallen but didn’t tell her anything. She also replies with that when I explain something about the religion I am in to her; she asked me first so I had reason to tell her about that topic.
What do I do? And are all Christians/Non-Catholics so arrogant of other religions? (She is not the first one to turn down Catholicism, my middle school principal said that Christianity was better than Catholicism. )
She also insults some of my other beliefs and qualities.
