Maria Valtorta: Jesus gives a definition of Satan

Jesus says to Maria Valtorta: «The primitive name was Lucifer: in the mind of God it meant" bishop or bearer of light "or of God, because God is Light. Second in beauty among all that is, it was a pure mirror that reflected the unsustainable Beauty. In the missions to men he would have been the executor of the will of God, the messenger of the decrees of goodness that the Creator would have transmitted to his blessed children without fault, to bring them
higher and higher in its resemblance. The bearer of the light, with the rays of this divine light that he carried, would have spoken to men, and they, being without fault, would have understood these flashes of harmonious words, all love and joy. Seeing himself in God, seeing himself, seeing himself in his companions, because God enveloped him in his light and blessed himself in the splendor of his archangel, and because the angels revered him as the most perfect mirror of God, he admired himself. He had to admire God alone. But in the being of all that is created, all the good and evil forces are present, and they agitate until one of the two parts wins to give good or bad, as in the atmosphere are all the gaseous elements: because they are necessary. Lucifer attracted pride to himself. He cultivated it, extended it. It became a weapon and seduction. He wanted more than he didn't. He wanted it all, he who was already a lot. He seduced the least attentive of his companions. It distracted them from contemplating God as supreme Beauty. Knowing the future wonders of God, he wanted to be him in the place of God. He laughs, with troubled thought, head of future men, adored as supreme power.
He thought, "I know the secret of God. I know the words. The drawing is known to me. I can do anything He wants. As I presided over the first creative operations I can proceed. I am". The word that only God can say was the cry of ruin of the proud. And it was Satan. It was "Satan". In truth I tell you that the name of Satan was not put by man, who also, by order and will of God, put a name to everything he knew to be, and that he still baptizes his discoveries with a name created by him. In truth I tell you that the name of Satan comes directly from God, and it is one of the first revelations that God made to the spirit of one of his poor children wandering on earth.
And as my Name Ss. Has the meaning I once told you, now listen to the meaning of this hideous name. Write as I tell you:
SATAN
Sacrilege Atheism Turpitude Anticarity Denial
Superb Opposing Tempter e
traitor Greedy Enemy
This is Satan. And this is those who are sick with Satanism. And again it is: seduction, cunning, darkness, agility, iniquity. The 5 cursed letters that make up his name, written in fire on his electrocuted forehead. The 5 cursed characteristics of the Corruptor against which my 5 blessed Wounds blaze, which with their pain save those who want to be saved from what Satan continually inoculates. The name of "demon, devil, beelzebub" can be of all dark spirits. But this is only "his" name. And in Heaven it is named only with that, because there the language of God is spoken, in faithfulness of love also to indicate what one wants, according to how God thought it. He is the "Contrary". What is the opposite of God. What is the opposite of God. And every action of his is the antithesis of the actions of God. And every study of his is to lead men to be opposed to God. That's what Satan is. It is "going against Me" in action. To my three theological virtues he opposes the triple concupiscence. To the four cardinals and to all the others that spring from Me, the serpentine nursery of its horrendous vices. But, as it is said that of all virtues the greatest is charity, so I say that of its anti-virtues the greatest and to Me repulsive is pride. Because all evil has come for it. This is why I say that, while I still sympathize with the weakness of the flesh that yields to the supply of lust, I say that I cannot sympathize with the pride that wants, as a new Satan, to compete with God. Are you unfair? No. Consider that lust is basically a vice of the lower part which in some has such voracious appetites, satisfied in moments of brutalization that it dulls. But pride is a vice of the upper part, consumed with acute and lucid intelligence, premeditated, lasting. It damages the part that most resembles God. Treads on the gem given by God. It communicates similarity with Lucifer. It sows pain more than flesh. Because the flesh can make a bride, a woman suffer. But pride can take victims on entire continents, in every class of people. Man has been ruined by pride and the world will perish. Faith languishes through pride. Pride: the most direct emanation of Satan. I have forgiven the great sinners of the sense because they were devoid of pride of spirit. But I could not redeem Doras, Giocana, Sadoc, Eli and others like them, because they were the "proud" ».
