I think that we will not deviate from our subject if we give here a more detailed account of this demonic calamity which torments mankind. Delusion is the devil substantially and existentially. Through wrongful and selfish thoughts and judgements he has severed himself from the truth, God, from whom he had been receiving his participation in the “well being” and the entire normal performance of his personality. Thus he became The delusion, because he has not been truly and correctly thinking and acting. Having then been subjected to a total reversal, he first revolted against his own self and then he passed on to his victims his own corruption.
According to our Fathers, only good has a real existence.The non good is devoid of personality and status.This is what has happened to the devil by necessity; He has lost his personality. However, when he is trying to assume a status and a personality, which he is naturally lacking, he forges it and this is what delusion is.
Of course the devil exists as an entity, because he has died in the face of the Lord as well as in the sense of any goodness, but he exists as a body of “death” in accordance with his corrupted entity. Nevertheless, he does not present himself under this nothingness but steals the methods and schemes of whatever is good, useful and beneficial- acting falsely and deceitfully- and deludes those who believe in him. He incessantly tries to haul human nature into the revolt of his own demise, either totally or partly. This act is and is called DELUSION.
Satan’s first frontal attack was seen during the first appearance of divine revelation. The Creator’s providence towards His created beings extends beyond His creating energy towards their preservation as a constant and prolonged intervention. The Devil cannot corrupt God’s constructive intervention towards the creation in accordance with the unspeakable and unfathomable ways of His divine All Might. Thus he deceitfully interferes with the prolonged preservation and stewardship of the creation, especially of the rational beings.
