Elder Paisios on Demons and the Power of the Cross
What is there to fear? Tagalakia have no power. Christ is all-powerful. Temptation is rotten to the core. Don’t you wear a Cross? The devil’s weapons are weak. Christ has armed us with His Cross. Only when we discard our spiritual weapons, then the enemy has power. An Orthodox priest showed a small Cross to a magician, which made the demon he invoked through his magic tremble.
