The optimistic explanation is the bishop doesn't believe in the devil. The logical explanation is worse.
I think the U.S. has less than 10 exorcists at last count.
I believe we have many more than that.
Where and what makes you believe that? I think it was Fr. Amorth who stated otherwise. AmChurch believes in psychology, not Satan. I know of a couple diocesan exorcists in the Wisconsin/Minnesota area. I would guess the FSSP has some which may operate in affiliated dioceses with the bishop's permission. California has none. This man has sought help all over the US. So far this is the only diocesan lead he has.
