Acts 8:9 Douay-Rheims

There was therefore great joy in that city. Now there was a certain man named Simon, who before had been a magician in that city, seducing the people of Samaria, giving out that he was some great one:

“And, thirdly, because after Christ's ascension into heaven the devils put forward certain men who said that they themselves were gods; and they were not only not persecuted by you, but even deemed worthy of honours. There was a Samaritan, Simon, a native of the village called Gitto, who in the reign of Claudius Caesar, and in your royal city of Rome, did mighty acts of magic, by virtue of the art of the devils operating in him. He was considered a god, and as a god was honoured by you with a statue, which statue was erected on the river Tiber, between the two bridges, and bore this inscription, in the language of Rome:-"Simoni Deo Sancto," "To Simon the holy God."And almost all the Samaritans, and a few even of other nations, worship him, and acknowledge him as the first god; and a woman, Helena, who went about with him at that time, and had formerly been a prostitute, they say is the first idea generated by him. And a man, Meander, also a Samaritan, of the town Capparetaea, a disciple of Simon, and inspired by devils, we know to have deceived many while he was in Antioch by his magical art. He persuaded those who adhered to him that they should never die, and even now there are some living who hold this opinion of his. And there is Marcion, a man of Pontus, who is even at this day alive, and teaching his disciples to believe in some other god greater than the Creator. And he, by the aid of the devils, has caused many of every nation to speak blasphemies, and to deny that God is the maker of this universe, and to assert that some other being, greater than He, has done greater works. All who take their opinions from these men, are, as we before said, called Christians; just as also those who do not agree with the philosophers in their doctrines, have yet in common with them the name of philosophers given to them. And whether they perpetrate those fabulous and shameful deeds-the upsetting of the lamp, and promiscuous intercourse, and eating human flesh-we know not; but we do know that they are neither persecuted nor put to death by you, at least on account of their opinions. But I have a treatise against all the heresies that have existed already composed, which, if you wish to read it, I will give you.”

“But the evil spirits were not satisfied with saying, before Christ's appearance, that those who were said to be sons of Jupiter were born of him; but after He had appeared, and been born among men, and when they learned how He had been foretold by the prophets, and knew that He should be believed on and looked for by every nation, they again, as was said above, put forward other men, the Samaritans Simon and Menander, who did many mighty works by magic, and deceived many, and still keep them deceived. For even among yourselves, as we said before, Simon was in the royal city Rome in the reign of Claudius Caesar, and so greatly astonished the sacred senate and people of the Romans, that he was considered a god, and honoured, like the others whom you honour as gods, with a statue. Wherefore we pray that the sacred senate and your people may, along with yourselves, be arbiters of this our memorial, in order that if any one be entangled by that man's doctrines, he may learn the truth, and so be able to escape error; and as for the statue, if you please, destroy it.”

“For I gave no thought to any of my people, that is, the Samaritans, when I had a communication in writing with Caesar, but stated that they were wrong in trusting to the magician Simon of their own nation, who, they say, is God above all power, and authority, and might.”

“Simon the Samaritan was that magician of whom Luke, the disciple and follower of the apostles, says, "But there was a certain man, Simon by name, who beforetime used magical arts in that city, and led astray the people of Samaria, declaring that he himself was some great one, to whom they all gave heed, from the least to the greatest, saying, This is the power of God, which is called great. And to him they had regard, because that of long time he had driven them mad by his sorceries." This Simon, then-who feigned faith, supposing that the apostles themselves performed their cures by the art of magic, and not by the power of God; and with respect to their filling with the Holy Ghost, through the imposition of hands, those that believed in God through Him who was preached by them, namely, Christ Jesus-suspecting that even this was done through a kind of greater knowledge of magic, and offering money to the apostles, thought he, too, might receive this power of bestowing the Holy Spirit on whomsoever he would,-was addressed in these words by Peter: "Thy money perish with thee, because thou hast thought that the gift of God can be purchased with money: thou hast neither part nor lot in this matter, for thy heart is not fight in the sight of God; for I perceive that thou art in the gall of bitterness, and in the bond of iniquity." He, then, not putting faith in God a whit the more, set himself eagerly to contend against the apostles, in order that he himself might seem to be a wonderful being, and applied himself with still greater zeal to the study of the whole magic art, that he might the better bewilder and overpower multitudes of men. Such was his procedure in the reign of Claudius Caesar, by whom also he is said to have been honoured with a statue, on account of his magical power. This man, then, was glorified by many as if he were a god; and he taught that it was himself who appeared among the Jews as the Son, but descended in Samaria as the Father while he came to other nations in the character of the Holy Spirit. He represented himself, in a word, as being the loftiest of all powers, that is, the Being who is the Father over all, and he allowed himself to be called by whatsoever title men were pleased to address him.”

“For thenceforward Simon Magus, just turned believer, (since he was still thinking somewhat of his juggling sect; to wit, that among the miracles of his profession he might buy even the gift of the Holy Spirit through imposition of hands) was cursed by the apostles, and ejected from the faith. Both he and that other magician, who was with Sergius Paulus, (since he began opposing himself to the same apostles) was mulcted with loss of eyes.”

“Many attempts were also wrought against the apostles by the sorcerers Simon and Elymas, but the blindness which struck (them) was no enchanter's trick.”
“Of these the first of all is Simon Magus, who in the Acts of the Apostles earned a condign and just sentence from the Apostle Peter. He had the hardihood to call himself the Supreme Virtue, that is, the Supreme God; and moreover, (to assert) that the universe had been originated by his angels; that he had descended in quest of an erring dµmon, which was Wisdom; that, in a phantasmal semblance of God, he had not suffered among the Jews, but was as if he had suffered.”

“It seems, then, expedient likewise to explain now the opinions of Simon, a native of Gitta, a village of Samaria; and we shall also prove that his successors, taking a starting-point from him, have endeavoured (to establish) similar opinions under a change of name. This Simon being an adept in sorceries, both making a mockery of many, partly according to the art of Thrasymedes, in the manner in which we have explained above, and partly also by the assistance of demons perpetrating his villany, attempted to deify himself. (But) the man was a (mere) cheat, and full of folly, and the Apostles reproved him in the Acts. With much greater wisdom and moderation than Simon, did Apsethus the Libyan, inflamed with a similar wish, endeavour to have himself considered a god in Libya, And inasmuch as his legendary system does not present any wide divergence from the inordinate desire of that silly Simon, it seems expedient to furnish an explanation of it, as one worthy of the attempt made by this man.”

“But that very sapient fellow Simon makes his statement thus, that there is an indefinite power, and that this is the root of the universe. And this indefinite power, he says, which is fire, is in itself not anything which is simple, as the gross bulk of speculators maintain, when they assert that there are four incomposite elements, and have supposed fire, as one of these, to be uncompounded. Simon, on the other hand, alleges that the nature of fire is twofold; and one portion of this twofold (nature) he calls a something secret, and another (a something) manifest. And he asserts that the secret is concealed in the manifest parts of the fire, and that the manifest parts of the fire have been produced from the secret. And he says that all the parts of the fire, visible and invisible, have been supposed to be in possession of a capacity of perception. The world, therefore, he says, that is begotten, has been produced from the unbegotten fire. And it commenced, he says, to exist thus: The Unbegotten One took six primal roots of the principle of generation from the principle of that fire. For he maintains that these roots have been generated in pairs from the fire; and these he denominates Mind and Intelligence, Voice and Name, Ratiocination and Reflection. And he asserts that in the six roots, at the same time, resides the indefinite power, which he affirms to be Him that stood, stands, and will stand. And when this one has been formed into a figure, He will, according to this heretic, exist in the six powers substantially and potentially. And He will be in magnitude and perfection one and the same with that unbegotten and indefinite power, possessing no attribute in any respect more deficient than that unbegotten, and unalterable, and indefinite power. If, however, He who stood, stands, and will stand, continues to exist only potentially in the six powers, and has not assumed any definite figure, He becomes, says Simon, utterly evanescent, and perishes. And this takes place in the same manner as the grammatical or geometrical capacity, which, though it has been implanted in man's soul, suffers extinction when it does not obtain (the assistance of) a master of either of these arts, who would indoctrinate that soul into its principles. Now Simon affirms that he himself is He who stood, stands, and will stand, and that He is a power that is above all things. So far, then, for the opinions of Simon likewise.”

“But Bernice, being asked, said: "These things are indeed as you have heard; and I will tell you other things respecting this same Simon, which perhaps you do not know. For he astonishes the whole city every day, by making spectres and ghosts appear in the midst of the market-place; and when he walks abroad, statues move, and many shadows go before him, which, he says, are souls of the dead. And many who attempted to prove him an impostor he speedily reconciled to him; and afterwards, under pretence of a banquet, having slain an ox, and given them to eat of it, he infected them with various diseases, and subjected them to demons. And in a word, having injured many, and being supposed to be a god, he is both feared and honoured. Wherefore I do not think that any one will be able to quench such a fire as has been kindled. For no one doubts his promises; but every one affirms that this is so. Wherefore, lest you should expose yourselves to danger, I advise you not to attempt anything against him until Peter come, who alone shall be able to resist such a power, being the most esteemed disciple of our Lord Jesus Christ. For so much do I fear this man, that if he had not elsewhere been vanquished in disputing with my lord Peter, I should counsel you to persuade even Peter himself not to attempt to oppose Simon."”

“"But there was a certain man, called Simon, which before time in the same city used sorcery, and bewitched the people of Samaria." Observe another trial, this affair of Simon. "Giving out," it says, "that he was himself some great one. To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God. And to him they had regard, because that of long time he had bewitched them with sorceries." "Of a long time" was the malady, but this man (Philip) brought them deliverance.”

“To whom they all gave heed,.... Were not only attentive to the strange things he did, and to the wonderful things he gave out concerning himself; but they believed what he said and did as real things, and were obedient to him: and that from the least to the greatest; which does not so much respect age, though the Ethiopic version renders it, "from the younger of them to the eldest of them", as state and condition; persons of every rank and quality, high and low, rich and poor, magistrates and subjects, from the meanest to the greatest of them; and so the Syriac version renders it, "both great", or "noble, and mean"; he drew the attention, and commanded the regard, both of princes and peasants, of the learned and unlearned, of the great men, and of the common people, who one and all wondered at him, and applauded him: saying, this man is the great power of God; or as the Alexandrian copy and some others, and the Vulgate Latin version read, "this is the power of God which is called great"; they took him for the supreme Deity, or as Justin Martyr (h) expresses it, they accounted him the first, or chief God, or they looked upon him to be the Messiah, "the great power of God": as the Syriac version renders it; and who should be great, and called the Son of the Highest, Luk 1:32.

“A certain man called Simon - In ancient ecclesiastical writers, we have the strangest account of this man; they say that he pretended to be the Father, who gave the law to Moses; that he came in the reign of Tiberius in the person of the Son; that he descended on the apostles on the day of pentecost, in flames of fire, in quality of the Holy Spirit; that he was the Messiah, the Paraclete, and Jupiter; that the woman who accompanied him, called Helena, was Minerva, or the first intelligence; with many other extravagancies which probably never had an existence. All that we know to be certain on this subject is, that he used sorcery, that he bewitched the people, and that he gave out himself to be some great one. This might be sufficient, were not men prone to be wise above what is written. Our word sorcerer, from the French sorcier, which, from the Latin sors, a lot, signifies the using of lots to draw presages concerning the future; a custom that prevailed in all countries, and was practised with a great variety of forms. On the word lot see the note, Lev 16:8, Lev 16:9; and Jos 14:2. The Greek word, μαγευων, signifies practising the rites or science of the Magi, or Mughan, the worshippers of fire among the Persians; the same as Majoos, and Majooseean, from which we have our word magician. See the note on Mat 2:1. And bewitched the people of Samaria - εξιϚων, Astonishing, amazing, or confounding the judgment of the people, from εξιϚημι, to remove out of a place or state, to be transported beyond one's self, to be out of one's wits; a word that expresses precisely the same effect which the tricks or legerdemain of a juggler produce in the minds of the common people who behold his feats. It is very likely that Simon was a man of this cast, for the east has always abounded in persons of this sort. The Persian, Arabian, Hindoo, and Chinese jugglers are notorious to the present day; and even while I write this, (July, 1813), three Indian jugglers, lately arrived, are astonishing the people of London; and if such persons can now interest and amaze the people of a city so cultivated and enlightened, what might not such do among the grosser people of Sychem or Sebaste, eighteen hundred years ago? That himself was some great one - That the feats which he performed sufficiently proved that he possessed a most powerful supernatural agency, and could do whatsoever he pleased.”
