That’s why I think everyone should remember they ARE catholic schools. I’ve read a lot of posts on CC saying that the schools, especially the Jesuit schools, are Catholic in name only but not in practice. That just isn’t true. They are welcoming, they provide a great education, but they are Catholic institutions run by Catholics who like crucifixes and statues of Mary and St. Francis around the grounds. I don’t think anyone should be surprised if a school puts up a chapel, more statues, more crucifixes even if they weren’t there previously. There are catholic universities that really wouldn’t work for any non-catholics (and won’t work for many catholics either), but it really is a personal decision whether a particular school is acceptable. Don’t expect the school to change.
Jewish friend was on bed rest at a Catholic hospital for about 6 weeks before her son was born. They took down the crucifix in her room. For Passover they special ordered her meals from a Kosher deli at no extra cost to her. If she’d wanted her tubes tied after delivering? No, that wasn’t going to happen in that facility. She picked the hospital she wanted but she had to accept its rules, decor, the fact that there were prayers over the intercom sometimes, Mass announcements, nuns running the place. She chose the hospital, but she had to accept the Catholic stuff that came with that choice. She was in the hospital over Easter, and there were Easter things everywhere. The hospital actually has a parish in it, so near Easter they have all the things any other parish would have - Mass, stations, baptism, confirmation. Everywhere.
Since the OP put the requirement for a non-secular school high on her list, I don’t think Fordham, BC, and Georgetown are going to work for her daughter.
