I don't know if you have any children, but would you care if he was after your child's soul?
The devil seeks the ruin of souls. Since the devil is the father of lies and the great deceiver, he cant ruin your soul if you are wary, which is what Fr. Amorths message is.
St. Michael the Archangel, defend us in the day of Battle; Be our safeguard against the wickedness and snares of the Devil. May God rebuke Him, we humbly pray, and do Thou, O Prince of the Heavenly Host, by the power of God, cast into Hell, Satan and all the other evil spirits, who prowl through the world, seeking the ruin of souls. Amen
