Acts 19, 13-17 Paul I know, but who are you?

(Acts 19, 13-17) Paul I know, but who are you?

[13] Then some itinerant Jewish exorcists tried to invoke the name of the Lord Jesus over those with evil spirits, saying, "I adjure you by the Jesus whom Paul preaches." [14] When the seven sons of Sceva, a Jewish high priest, tried to do this, [15] the evil spirit said to them in reply, "Jesus I recognize, Paul I know, but who are you?" [16] The person with the evil spirit then sprang at them and subdued them all. He so overpowered them that they fled naked and wounded from that house. [17] When this became known to all the Jews and Greeks who lived in Ephesus, fear fell upon them all, and the name of the Lord Jesus was held in great esteem.

(CCC 2851) In this petition, evil is not an abstraction, but refers to a person, Satan, the Evil One, the angel who opposes God. The devil (dia-bolos) is the one who "throws himself across" God's plan and his work of salvation accomplished in Christ. (CCC 434) Jesus' Resurrection glorifies the name of the Saviour God, for from that time on it is the name of Jesus that fully manifests the supreme power of the "name which is above every name" (Phil 2:9-10; cf. Jn 12:28). The evil spirits fear his name; in his name his disciples perform miracles, for the Father grants all they ask in this name (Cf. Acts 16:16-18; 19:13-16; Mk 16:17; Jn 15:16). (CCC 2852) "A murderer from the beginning,… a liar and the father of lies," Satan is "the deceiver of the whole world" (Jn 8:44; Rev 12:9). Through him sin and death entered the world and by his definitive defeat all creation will be "freed from the corruption of sin and death" (Roman Missal, Eucharistic Prayer IV, 125). Now "we know that anyone born of God does not sin, but He who was born of God keeps him, and the evil one does not touch him. We know that we are of God, and the whole world is in the power of the evil one" (1 Jn 5:18-19). The Lord who has taken away your sin and pardoned your faults also protects you and keeps you from the wiles of your adversary the devil, so that the enemy, who is accustomed to leading into sin, may not surprise you. One who entrusts himself to God does not dread the devil. "If God is for us, who is against us?" (St. Ambrose, De Sacr. 5, 4, 30: PL 16, 454; cf. Rom 8:31).
