There are plenty of Jesuits and other religious at BC. Someone posted here on CC that they didn’t like the feel of BC because there were so many Religious seen walking around campus. Gee, it’s almost like they own the place (they DO!). There are about 150 priests with BC as their assignment, either staff, faculty, or students. There are also additional Religious around campus as nuns, priests, brothers attend school there.
I think some people are surprised just how much religion is incorporated into daily life. There are more than just a few crosses and statues around the place. The administration, the health care system (and insurance), the calendar incorporate the Catholic beliefs. If you can go with the flow, they are happy to have you and you will get a great education. There are beautiful buildings on campus, and they definitely ‘religious themed’ with stained glass windows and crosses.
But if you don’t like it, go to BU or MIT or Harvard.
I do find it curious that you don’t want a religious presence, but you’ve looked at BC, Georgetown, Providence, Notre Dame. It seems you DO want a religious school.
