“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 right in the sight of God; for I perceive that thou art in the gall of bitterness, and in the bond of iniquity."”

“Therefore this man also, who in buying himself has bought the Spirit of Christ, will hear that word, "Your money perish with you, since you have thought that the grace of God is to be had at a price!" Yet who will despise him for being (what he is), a denier? For what says that extorter? Give me money: assuredly that he may not deliver him up, since he tries to sell you nothing else than that which he is going to give you for money.”

“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.”

“That the grace of God ought to be without price. In the Acts of the Apostles: "Thy money be in perdition with thyself, because thou hast thought that the grace of God is possessed by money." Also in the Gospel: "Freely ye have received, freely give." Also in the same place: "Ye have made my Father's house a house of merchandise; and ye have made the house of prayer a den of thieves." Also in Isaiah: "Ye who thirst, go to the water, and as many as have not money: go, and buy, and drink without money." Also in the Apocalypse: "I am Alpha and Omega, the beginning and the end. I will give to him that thirsteth from the fountain of the water of life freely. He who shall overcome shall possess these things, and their inheritance; and I will be his God, and he shall be my son."”

“Immediately, the above-mentioned sorcerer, as if struck in the eyes of his mind by a divine and marvelous flash when formerly in Judea he had been detected for his evil deeds by the apostle Peter, set out on a very long journey overseas from east to west and went off in flight, thinking that only in this way could he live according to his wish. And when he came to the city of the Romans, the power that obsessed him cooperated with him greatly, and in short time he was so successful in his undertakings that he was honored as a god by the erection of a statue by those in this city. However, his affairs did not prosper for long. Close on him in the same reign of Claudius, the all-good and kindly providence of the universe guided Peter, the great and mighty one of the apostles, because of his virtue the spokesman for all the others to Rome, as if against a great corrupter of life. And he, like a noble general of God, clad in divine armor, conveys the costly merchandise of the light from the east to those in the west, preaching the light itself and the Word that saves souls, the proclamation of the kingdom of heaven.”

“He who through ignorance wishes to buy is less guilty than he who sells the gift of God, making it a business transaction. And, if you sell what you have received as a gift, you will be deprived of its grace, as if you had been sold to Satan. Furthermore, you are introducing into the church, where we have been entrusted with the body and blood of Christ, the bartering of material for spiritual things.”

“He offered money to people without possessions, and that too after seeing people bring the price of what they sold and lay it at the feet of the apostles. He did not realize that they who trod underfoot the wealth offered for the sustenance of the poor would surely never sell him the power of the Holy Spirit for a price.”

“Then, when Simon, depraved by long practice of magic, had thought he could gain by money the power of conferring the grace of Christ and the infusion of the Holy Spirit, Peter said, "You have no part in this faith, for your heart is not right with God. Repent therefore of your wickedness, and pray to the Lord, if perhaps this thought of your heart may be forgiven, for I see that you are in the bond of iniquity and in the bitterness of gall." We see that Peter by his apostolic authority condemns him who blasphemes against the Holy Spirit through vain magic, and all the more because he had no clear consciousness of faith. And yet he did not exclude him from the hope of forgiveness, for he called him to repentance.”

“How was it then that they did not strike him dead, as they did Ananias and Sapphira? Because even in the old times, he that gathered sticks on the sabbath-day was put to death as a warning to others and in no other instance did any suffer the same fate. So too on the present occasion, "Peter said to him, Thy money perish, because thou hast imagined that the gift of God is to be purchased with money." Why had not these received the Holy Ghost, when baptized? Either because Philip kept this honor for the Apostles; or, because he had not this gift to impart; or, he was one of the Seven: which is rather to be said. "Thy money with thee to perdition": since thou hast not used it as it ought to be used. These are not words of imprecation, but of chastisement. "To thee," he says, be it to thee: being such. As if one should say, Let it perish along with thy purpose. Hast thou so mean conceptions of the gift of God, that thou hast imagined it to be altogether a thing of man? It is not this. Wherefore also Peter well calls the affair a gift: "Thou hast thought that the gift of God may be purchased with money." Dost thou observe how on all occasions they are clean from money? "For thine heart is not right in the sight of God." Dost thou see how he does all of malice? To be simple, however, was the thing needed. For had it been done with simplicity, he would have even welcomed his willing mind. Seest thou that to have mean conceptions of great things is to sin doubly?”

“Thou hast neither part nor lot in this matter,.... Or business of the gift of the Holy Ghost; signifying, that as he had not the grace of the Spirit of God implanted in him, so he should not have any of the gifts of the Spirit bestowed on him; and much less a power of communicating them to others, through laying on of hands: or "in this word"; the word of the Gospel, preached by the apostles; and in any of the blessings published in it, as the forgiveness of sins, a justifying righteousness, and eternal life; and so the Syraic version renders it, "in this faith"; neither in the grace of faith, nor in the doctrine of faith: it seems to answer to a way of speaking frequently used among the Jews, that such and such persons, , "have no part or lot", in the world to come (i). The Ethiopic version reads, "because of this thy word"; because for his money, he had desired to have a power of bestowing the Holy Ghost on persons, through the imposition of his hands; which showed he had no share in the grace of God, and would have no part in eternal life, thus living and dying: for thy heart is not right in the sight of God; he had not a clean heart, nor a right spirit created in him; he had not true principles of grace wrought in him; his heart was full of covetousness, ambition, and hypocrisy; he had no good designs, ends, and aims, in what he said and did; in his profession of faith, in his baptism, in his attendance on Philip's ministry, and in his request for the above power, of conferring the Holy Ghost: his view was not the spread and confirmation of the Gospel, or the enlargement of the kingdom and interest of Christ, and the glory of God, but his own applause and worldly interest; and therefore, however he might be thought of by men, to be a good and disinterested man, he was otherwise in the sight of God, who is the searcher of the heart, and the trier of the reins of the children of men. (i) Misn. Sanhedrin, c. 11. sect. 1.”

“Thy money perish with thee - This is an awful declaration; and imports thus much, that if he did not repent, he and his ill-gotten goods would perish together; his money should be dissipated, and his soul go into perdition. That the gift of God may be purchased - Peter takes care to inform not only Simon, but all to whom these presents may come, that the Spirit of God is the gift of God alone, and consequently cannot be purchased with money; for what reward can He receive from his creatures, to whom the silver and the gold belong, the cattle on a thousand hills, the earth and its fullness!”

“Thy money perish with thee--that is, "Accursed be thou and thy money with thee." It is the language of mingled horror and indignation, not unlike our Lord's rebuke of Peter himself (Mat 16:23).”

“Your money. Not ours, who do not covet it, but yours, which you compare to the Spirit, that you may sell it for him, and buy it with the Spirit. He wished to buy the Spirit for this reason, that selling him to others he might be able to receive more. Money. From this an example is taken, that the alms of the lost be not received. The apostles, not wanting the money, say, be it with you, that is, keep your own, and this, unto perdition, that, the money being unjustly gathered, you may pay eternal punishment.”
