How catholic is Villanova?
How Catholic do you want it to be?
Will you see crosses and crucifixes and priests? Yes. Will students say the rosary on their way to class and try to convert you? There may be a zealot or 2 (like anywhere), but in general, no.
It’s the regular amount of Catholic. (i.e., it’s a catholic university )
It is a Catholic school and from what I saw on a quick google search it appears that about 75% of students are Catholic.
My S went to a Jesuit university and I would think Villanova is similar in tone. I believe to be comfortable at a Catholic college one needs to ; 1) be respectful of religion; 2) have no issue with seeing some religious symbols on campus (ex. crucifix); and 3) look at the core curriculum and be fine with the idea of taking any required philosophy/theology courses.
