Catholic Missionary at a Catholic School

Over Christmas break is was able to figure out just how this year has felt in terms of teaching theology at this Catholic school. I'm doing my best to teach a group of teenagers the Catholic faith. The tough aspects and the easy to understand, all with compassion and understanding. The reactions I've gotten coupled with the eye opening realizations have been fun but also sad. Questions that have been both encouraging while also slightly unbelievable. I've got students who have gone to a Catholic school for 10+ years who are learning new things, simple things, from me.
I feel like a Catholic missionary bringing the Catholic faith to a Catholic school.
It's a testament to what Catholic education has become across much of the United States. Being Catholic in name but not in substance. This Catholic school like many is not really ingrained into the community, rather it has created its own little community that it thrives off of. I have a few coworkers who have been at the school for 20+ years. They've seen small changes over the years, but at the end of the day the school hasn't really changed much. Being proud to be a Catholic school but failing to be authentically Catholic has been the way things have gone for a long time as far as I can tell.
I have a student who is extremely bright. She has recently been accepted to Notre Dame and is one of those students who has challenging questions every day and is always ready to pounce should I slip up. I mentioned to her class how I feel like a missionary and all she could do was laugh. She understood completely and the only reaction she could muster was full on hysterical laughter.
So I've got one semester left to continue my missionary journey at this school and hopefully leave it better than I found it.

Peace all
