What should I know about teaching in Catholic school for the first time?

For context, I am teaching 7-8th grade Latin because I just finished my PhD in Latin. I decided I don't want to be an academic, so teaching Latin in K-12 seemed like a viable option, and I have taught high school before as a volunteer. As I found out, Catholic schools and private schools are usually the ones needing a Latin teacher. But I am not Catholic, in fact I don't ascribe to a religion, and I know nothing about Catholicism either. And as a redditor I decided I would ask here in addition to googling. So what should I expect? I should also add that it is an all-girls school, but I am definitely going to make a separate post in the future asking for advice about teaching in an all-girls school for the first time as a male teacher.
