His full-time occupation necessitates an immersion in the spiritual life in all its aspects, so I wouldn't necessarily expect him to be awestruck by this particular situation. Also, the Catholic Church carefully examines these cases before becoming involved and only proceeds in those in which the evidence clearly warrants intervention of this sort.
No, I wouldn’t expect awestruck, and I’m not awestruck of Satan myself. His power is limited and he’s on a short leash.
I just expect a minister to warn others of the seriousness of possession / demonic activity (including the media), to follow scripture on how to approach it (prayerfully - being strong in faith), and to make sure there are no weak ones nearby.
I take it seriously because it’s a dangerous situation.
