The fact is that you don't know what instruction/training those disciples received. The Church doesn't do things 'man's way'. It does things God's way with the authority He bestowed upon it continuing on in His absence under the guidance of the Paraclete.
"Then calling together the twelve apostles, He gave them power and authority over all devils, and to cure diseases." Luke 9:1
"And after these things the Lord appointed also other seventy-two: and He sent them two and two before His face into every city and place whither He himself was to come." Luke 10:1
"But the Paraclete, the Holy Ghost, whom the Father will send in My name, He will teach you all things, and bring all things to your mind, whatsoever I shall have said to you." John 14:26
"But there are also many other things which Jesus did; which, if they were written every one, the world itself, I think, would not be able to contain the books that should be written." John 21:25
The New York archdiocese did not respond to questions about what McManus will say, but according to the Catholic News Service, he likely will be discussing how to tell if someone is possessed by a demon.
Before any exorcism can take place, a priest must look for the telltale signs, such as a violent reaction to holy water, super strength, aversion to the name of Jesus or Mary and speaking in tongues.
Also, the possibly possessed person must be checked out by a psychologist to make sure they are not mentally ill before a bishop will allow an exorcism to proceed.
Once an exorcism is initiated, the priest will try to drive the demon out of the possessed person by sprinkling holy water, reciting psalms and laying on hands.
Not one mention of the Holy Ghost involved in the determination as to whether a person is possessed.
Not one mention of the name of Jesus being used to cast them out. It is the only thing demons have to obey.
