The Demon Collapsed To The Ground And Was Begging Me To Stop Praying & To Stop Using The Holy Water

Satan or the devil and the other demons are fallen angels who have freely refused to serve God and his plan. Their choice against God is definitive. They try to associate man in their revolt against God.
“A murderer from the beginning, . . . a liar and the father of lies,” Satan is “the deceiver of the whole world.” 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.” 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.”

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?”
Behind the disobedient choice of our first parents lurks a seductive voice, opposed to God, which makes them fall into death out of envy. Scripture and the Church’s Tradition see in this being a fallen angel, called “Satan” or the “devil”.The Church teaches that Satan was at first a good angel, made by God: “The devil and the other demons were indeed created naturally good by God, but they became evil by their own doing.”
The evangelists indicate the salvific meaning of this mysterious event: Jesus is the new Adam who remained faithful just where the first Adam had given in to temptation. Jesus fulfills Israel’s vocation perfectly: in contrast to those who had once provoked God during forty years in the desert, Christ reveals himself as God’s Servant, totally obedient to the divine will. In this, Jesus is the devil’s conqueror: he “binds the strong man” to take back his plunder. Jesus’ victory over the tempter in the desert anticipates victory at the Passion, the supreme act of obedience of his filial love for the Father.
