The Bible teaches that Satan is a fallen angel tempted by pride. He is said to be a seducer originally created as good and whose rebellion against the divine will is reflected in the temptation that he offered to Adam and Eve in the Garden of Eden.
The scene is the garden of Eden. The characters are God, the serpent, Adam, and Eve. The devil has just deceived Eve, and through her, Adam. With demonic pride in destruction, he has successfully marred God’s handiwork of creation, and dragged human beings—for whom God has a special love—into death and misery.

God starts by addressing Satan, telling him he is going to eat dirt for the rest of his days. Then he reveals something that makes Satan cringe in horror—his ultimate defeat will come at the hands of a woman.

God said ” I will establish a feud between thee and the woman, between thy offspring and hers; she is to crush thy head, while thou dost lie in ambush at her heels”

Satan is a master theologian. He’s talked to God, interacted with God, believes in God’s existence, and knows more about God’s attributes and abilities than most…and yet Satan doesn’t love God. 

Very few people believe in the devil these days,” stated Fulton Sheen in 1958, “which suits the devil very well.

Do not be deceived. Satan is real and we must resist him, strong in our faith. However, do not be so terrified that you forget that God, His angels, and the grace He bestows on us are more powerful and that God limits what demons can do. Trust God; call to Him; frequently recite the 91st Psalm. Be sober and watchful and stay distant from the once-glorious fallen angels we rightly call demons.

Let us ask St. Michael, the Archangel for protection

St. Michael the Archangel, defend us in battle, be our protection 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 evil spirits who prowl about the world seeking the ruin of souls.
Amen.
