All Jesuits are catholics but not all catholics are jesuits. Point being, from my experience, a jesuit education is different and better than a diocesan type catholic education. Just like back in the day a specific order catholic church was different and better than a standard diocesan money laundering mill, I mean church.
Many diocesan experiences I had, which I won't get into here, and happened both in cle and Florida, is what turned me into a recovering catholic.
I dont believe 25% of Ignatius is non-catholic. Unless the experience radically changed, you would have to really be good at faking it to not stick out.
I dont believe that percentage breakdown is relevant to the turn in football. Rather, it is kids are drawn to other sports (soccer, hockey, rugby) as well as the first pull to the school, mostly, is the education.
I have witnessed said current student and parents be shell-shocked freshman year when couldn't cut the mustard academically to be eligible for sports. It improved this year, but it reinforces my view that the perception of the Ignatius experience by those who haven't endured it is radically wrong when they think item A is first and foremost, and in truth is it is a few rungs down the hierarchy. Making boys into great students, men, and future leader is the true priority A.
