“Chief Exorcist” is a general label because of his age and experience and the fact that Fr. Amorth established the international group of Exorcists which he is only the entitled leader due to his retirement.
I believe he refers to all the cases he’s asked to assess - whether they are psychological in nature, etc. And he can “farm” them out to other exorcists. Also the cases begun by others with less relief are often brought to him as last resort. He also sees same individuals often over a length of time. Exorcisms can last for years sometimes - depending on many things.
Someone mentioned as seemingly odd that the Vatican has exorcists. Well, Christ began the Church’s exorcisms Himself and the Church continues what He taught and gave power to.
Some of the Vatican’s “hiding” could be more of just not advertising events in care for family members involved or cases still being investigated.
Otherwise, in today’s anti-Church bias, advertising every event would only add more fuel to the atheistic ranting fire. The present Pope is really getting the secular/atheistic forces’ guns in his face lately. Pray for him.
Does he speak for the Vatican? Or not?
