Do penance therefore for this thy wickedness; and pray to God, that perhaps this thought of thy heart may be forgiven thee.

“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.”

“"Repent therefore of this thy wickedness and pray God, if perhaps the thought of thine heart may be forgiven thee. For I perceive the bond of iniquity." Once more he brings to light what was in the thoughts, because Simon thought to escape detection. "If perchance it may be forgiven thee." Not as though it would not have been pardoned, had he wept, but this is the manner of the Prophet also, to denounce absolutely, and not to say, "Howbeit, if thou do this, thy sin shall be forgiven," but that in any wise the punishment shall take effect. 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? Accordingly, two things he bids him: "Repent and pray, if haply the thought of thine heart may be forgiven thee." Seest thou it was a wicked thought he had entertained? Therefore he says, "If haply it may be forgiven thee": because he knew him to be incorrigible. "For I perceive that thou art in the gall of bitterness, and in the bond of iniquity." Words of exceeding wrath! But otherwise he did not punish him: that faith may not thereafter be of compulsion; that the matter may not seem to be carried ruthlessly; that he may introduce the subject of repentance: or also, because it suffices for correction to have convicted him, to have told him what was in his heart, to have brought him to confess himself overcome.”

“For I perceive that thou art in the gall of bitterness,.... Alluding to Deu 29:18 with which compare Heb 12:15 and signifying, that he was in a state of nature and unregeneracy; under the power and dominion of covetousness, ambition, and hypocrisy; and in a way pernicious to himself, infectious to others, and ungrateful to God, and to good men; and that instead of the root of the matter, the truth of grace being in him, there was nothing in him but the bitter root of sin; which bore gall and wormwood, and everything that was nauseous and disagreeable: and in the bond of iniquity; referring to Pro 5:22 and suggesting, that he was held fast bound in the bonds of sin, and with the cords of iniquity, or was entirely under the government of his lusts: the preposition which we render "in", may retain here, as is by some observed, its proper sense of "for", or "into"; and have the same signification it has in Heb 1:5 "I will be to him for a father", or "a father", and "he shall be to me for a son", or "a son": and then the sense of Peter is, I plainly perceive and clearly see by thy words and actions, that thou art nothing else but a lump of bitter gall, and a bundle of sin and wickedness.”

“Repent therefore of this thy wickedness - St. Peter did not suppose his case to be utterly hopeless; though his sin, considered in its motives and objects, was of the most heinous kind. If perhaps the thought of thine heart may be forgiven thee - His sin, as yet, only existed in thought and purpose; and therefore it is said, if perhaps the thought of thine heart may be forgiven.”

“That perhaps this thought of thy heart may be forgiven thee. The word perhaps, as the interpreters commonly observe on this and other places, many times does not imply any doubt or uncertainty. There could be no doubt, says St. Chrysostom, only as to his repenting: if he repented, it is certain he would find remission of his sins. (Witham) — St. Augustine (ep. cviii.) understands the text, metanoeson apo , &c. of penance done for heinous offences in the primitive Church, and teaches us to translate it thus, as it is in the Vulgate, both here and 2 Corinthians xii. 21, and Apocalypse ix. 21, and adds, that very good men do daily penance for venial sins, by fasting, prayer, and alms.”

“Do penance. For your covetousness, and the depraved sense by which you thought that a bargain could be made concerning the Spirit. That all may see what you are. Not that Peter is ignorant that he will not do penance, but because it is just to preach to all, he does his own office, that the man may be inexcusable. He is rebuked before all also, lest they be deceived by him any longer. Ask God. To whom the heart lies open, of whom the Prophet: How good is God to Israel; whom no one can deceive, because the Holy Spirit of discipline will flee what is feigned.”
