Jealousy does a lot of harm to the other person. The one who puts the evil eye on the one who is jealous of, does not even think that he is doing so much harm. But when the other person is a man of God and confesses frequently and receives communion and has the Cross on him, nothing can touch him. Even if all the demons will fall upon him, will accomplish nothing.
Saint Porphyrios (Bairaktaris) the Kafsokalyvite
