When the devil sees this, he always slinks back to where he came from.
During the 10th century, there lived a holy monk known as Peter Damian, who left the world to become a hermit. However, he couldn’t stand to see the world crumble around him, and so he left his hermitage to help reform the Church.
Peter Damian recognized the presence of evil and did what he could to expel its hold on certain members of the clergy.
When writing to a nephew, Peter Damian revealed to him what he saw as a powerful weapon against the devil.
If I may speak figuratively, drive out the roaring beasts from your domain; do not cease from protecting yourself daily by receiving the Flesh and Blood of the Lord. Let your secret foe see your lips reddened with the Blood of Christ. He will shudder, cower back, and flee to his dark, dank retreat.
He is referring to the worthy reception of Holy Communion at Mass, a potent weapon that crushes the head of the serpent every time.
Exorcists agree that the frequent reception of Holy Communion is a vital way to prevent the demon from working in your heart.
If you need to root out sin and the presence of the devil in your life, go to confession and receive the Eucharist on a regular basis. The devil will have no choice but to go back to his “dark, dank retreat.”
