No, I think he's saying that he wouldn't expect the world to infest a Bible college to the extent it might infest someplace actively trying to integrate faith into the life of a larger school.
A Bible college (unless I'm misunderstanding your term) is more analogous to a Catholic seminary than to someplace like Notre Dame. Aren't most of the people there studying for the ministry, interested in marrying a minister, or otherwise studying some faith-related subject ... hence the name "Bible College"?
A better analogy to e.g., Notre Dame would be someplace like Baylor. AFAIK, Baylor is staying pretty solid. (My wife went there for a time, and still gets some of their literature.) But they have a continuous fight on their hands.
Most of the larger, originally Protestant schools long ago became completely secularized, though. The Catholic schools apostatized in the 1960's after Humanae Vitae (the reiteration of the condemnation of contraception).
There are only about 10 authentically Catholic colleges left in the US, none of which are on this list.
The one I mentioned offers a Bachelors degree in Elementary Education. Fully accredited, too.
But, I didn't limit my list to Bible colleges; he did. I also mentioned Oral Roberts University. Certainly ORU appeals to more than just ministers and marrying.
At any rate, thanks for mentioning Baylor. It may be the best example of the point I was trying to make.

I know the one you sited, then there's Ave Maria, FL, Univ. of Dayton,
What are the others?
