I just came to this passage from Interview with an Exorcist:
“. . . To compensate for this potential source of pride, God normally allows the exorcist to suffer the misunderstanding and ridicule of many of his brother priests. As such, works all his life between being admired and thanked by some and bitterly despised and persecuted by others. This helps him grow in the virtue of humility.
Every exorcist knows fellow clergymen who think he is crazy and that his work is a danger to the reputation and image of the Church. Unfortunately, I do not know of any exorcist who has not had to suffer at the hands of priests determined to speak about and end the ‘scandal’ of ‘medieval superstition’ (i.e. exorcism) for the ‘good of the Church.’
Whoever is named to the ministry of exorcist should not think that the persecution he suffers is merely the result of misunderstanding, i.e., that it will only last until others see the fruits of exorcism and the good sense with which he works. This is urged on by Satan, who wants to discourage the exorcist at all costs.
Unfortunately, the persecution exorcists endure is not something that happens occasionally or only to some. Everyone who serves as an exorcist will experience it to one degree or another. God desires that the ministry always be done from the Cross. If a priest is not willing to bear this burden, he should not accept the ministry.”
And that goes for every aspect of priestly ministry, though the exorcist and his ministry is a special case. Moreover, this persecution will not be limited by any means to one’s fellow priests. Persecution instigated by Satan can come from anywhere, even from those who have been beneficiaries of one’s ministry but have subsequently given themselves to living life apart from Christ and the salvation He came to bring.
Having said that, the mockery I’ve received from priests, even otherwise good, orthodox, well meaning priests, screams of Satan’s intervention. I remember especially the mockery of one particular priest, which seemed less to have anything to do with anything merely along the lines of liberal political correctness, for what he presented was much more along the lines of a personal attack based on… what?… I don’t know… but such mockery! So unpriestly! Anyway, let’s just remember that we are not against any flesh and blood, but against Satan and his minions.
Not only should would-be exorcists not accept the ministry of exorcism if they have a sense of entitlement absolving them from the ridicule of fellow priests, I also think that would-be priests should not be ordained until they clearly understand that every time they offer the Holy Sacrifice of the Mass, they are before all hell breaking loose on Calvary. If they cannot accept this, how can they put themselves forward to act in the Person of Christ? If any priest thinks that exorcism is a medieval superstition, he should be instructed as to his error and, if unwilling to accept the truth of Christ’s own ministry of exoricism, should be laicized. Period.
We are at war. Read about it in Genesis 3,15. Read about it in the Gospels. Soldiers who deny there is a war are useless in battle. All they can do is ridicule and mock as they watch their fellow soldiers die for the cause. And our cause is Christ Jesus, who is our Leader in the battle.
Accompany me, Father George David Byers, S.S.L., S.T.D., as I begin life as a Catholic Priest-Hermit by choice. Holy Souls Hermitage is dedicated to the sanctification of my fellow priests, bishops, deacons & seminarians going through the purgatory of this life or the next. Prayer and sacrifice go up, of course, for both Benedict XVI and the next Successor of Saint Peter. 
This connects with yesterday’s Scripture readings. “No prophet is accepted in his own country.” Naaman the Syrian is healed of his leprosy, and Jesus is rejected by his hometown.
Jesus healed many who possessed by the the devil in his ministry. He showed us the evil one exists and we all are in this spiritual battle until the end. We thank the Lord for priests who are collaborating with God to heal those who suffer from the assaults of the devil. Jesus gave the example in which his priests are to work with Him in saving souls. A priest who does not act with compassion to those who are carrying this kind of cross needs lots of prayers for conversion. A priest who avoids pain or sufferings or lives a life of earthy commodity and self promotion for earthly position in the Church is not worthy to be called a priest. I know people who have been freed from Satan‘s snare that are very grateful to the exorcists who have shown them what Jesus has done in their lives. They are thankful to the Church for having these priests who are courageous in risking their lives to save others. This is true love that comes from putting the good of others before oneself. Isn‘t this what Jesus did when He offered himself up to be crucified for you and me? There is no greater love than this, that a man give up his life for his friends. We should not love in words but in deeds. Our Lord gave us the example what love means. Those good people who are thankful to the Lord and exorcists are indeed great examples of grateful souls who obey the exorcists and strive to live a Christian life in friendship with God. There are also cases of those who were once freed but did not persevere in living a good Christian life. They fell even worse as prey of the devil by their own faults and living lives far from God, so the devil‘s attack is worse because of their own self will.. This is a tragedy that all must avoid at all costs. Unfortunately, often they blame it on others, who have tried with the mandate of the Church to minister to them. No one can live a sacramental life for anyone else. Everyone has the responsibility to live the teachings of Christ. Unless we become like little children we will not enter the kingdom of heaven.
