I’m not saying he is a bad guy (as some here seem to believe). Indeed he fills an important educational void for the contemporary illiterate Catholic. He is at the level of your higher quality TV evangelist, Mundelein notwithstanding. But the mere fact his name is akin to a “household word” and many folks own his rather pricey paperbacks, speaks against his eligibility for this important and possibly decades-long appointment. Good bishops are not products of Madison Avenue, IMHO.
If he is not educating Catholics with the True Catholic Faith, then he does not fill a void. On the contrary, he adds to it.
