The problem of secular humanism, and deChristianization, at Notre Dame has been going on for 45 years! So much for the need to take the longer view. Bishops have a responsibility to students, parents, and potential job seekers, who think this and other institutions are Catholic, when they are not.
The leaders of Notre Dame are lying, claiming it is Catholic. We can’t blame the bishop for their sin. But the bishop has a responsibility, after meeting and discussing and trying to dissuade people from lying, to make sure the truth gets out there. The bishop is doing his job, issuing this statement, and the diocesan website does not list Notre Dame as a local Catholic institution at all. Notre Dame is too wealthy and national for one bishop to have much impact.
But there are many smaller faux-Catholic institutions that are more dependent on the lingering reputation of being Catholic. They still get gifts from donors, alumni, parents pay extra-high tuition, all in the inaccurate perception that those institutions are Catholic. Prolifers can ask their diocese to stop referring to them as Catholic. They can contact the college’s big donors, alumni associations, etc, and get the word out that this institution is not what it formerly was, it is now secular. They can identify colleges that are genuinely prolife (Christendom, Steubenville, etc) and get the diocesan newspaper and Catholic high schools to promote them instead.
If a religious order - Holy Cross, Jesuits, etc - continues to allow their name as part of misleading advertising, we should mount campaigns to persuade those religious orders to either reform the college, or withdraw their name from it.
