Andreas of Caesarea : Peter says this so that people will not just listen to everyone who claims to be a prophet, without discerning whether they really are or not. He tells them to be careful not to listen to false prophets instead of the true ones. — CATENA Bede : And they deny the Lord who bought them, etc. Concerning this buyer, Paul also says: "For you were bought at a great price; glorify and carry God in your body" (1 Cor. 6). Rightly indeed do they bring upon themselves swift destruction, who, denying their Redeemer, refuse to rightly confess Him and glorify, and by doing good, to bear Him in their own body: which all heretics do; for Arius, who says that our Redeemer is lesser than the Father in divinity, and Photinus, who says: "Christ is a man, not God," and Manichaeus, who says: "Christ is only God, not truly man," and Ebion, who says: "Christ did not exist before Mary, He took His origin from her," and Apollinaris, who says: "Christ is only God and flesh, never having taken a rational soul," and Pelagius, who says: "Christ is not the Redeemer of infants in baptism, because they, conceived without iniquities and born from their mother without sins, have no sin that must be forgiven to them, and therefore Christ is not the Savior of all the elect"; and other heretics with them indeed deny the Lord who bought them with the price of His own blood, because they proclaim Him not as truth reveals but as they themselves imagine. And therefore, made alien from the Redeemer, nothing is more certain than that they expect the pit of destruction. — Commentary on the Catholic Epistles Bede : To their own destruction. For those who attempt to corrupt the holy Scriptures and to disturb and pervert the Catholic faith bring condemnation upon themselves in this. However, the Church of Christ, having dispelled the darkness of errors, enjoys its true light. Hence, it is well said at the end of the Apocalypse, which is the closing and, as it were, the seal of all divine Scripture: If anyone adds to these things, God will add to him the plagues written in this book; and if anyone takes away from the words of the book of this prophecy, God will take away his part from the book of life and from the holy city, and from the things which are written in this book (Apocalypse XXII). The difficult things to understand in the Epistles of Paul, which he says are distorted by the unlearned and unstable, are especially those in which he speaks about the grace of God that justifies the ungodly (Romans IV), that is, makes the ungodly righteous. For he himself says: Where sin abounded, grace did much more abound (Romans V). Those who did not understand this thought he was saying: Let us do evil that good may come (Romans III). But far be it from Paul to teach his listeners to do evil to achieve good, for his entire intention is to restrain from evil and to call as many as possible to do good. But when he says, Where sin abounded, grace did much more abound (Romans V), he thereby commends the gift of grace more strongly, which is accustomed to forgive both great sins and lesser ones when people convert. And the greater the sins committed before conversion, the greater the forgiveness received through the gift of grace. Therefore the Apostle speaks thus about the sins we have already committed, so that no one should perish from despair of forgiveness because of the enormity of his crimes; but, as the enemies interpreted, he was not urging to commit more sins to receive greater good through them. Hence the blessed Peter rightly adds by way of admonition: — Commentary on the Catholic Epistles Didache : And every prophet that speaketh in the Spirit ye shall neither try nor judge; for every sin shall be forgiven, but this sin shall not be forgiven. But not every one that speaketh in the Spirit is a prophet; but only if he hold the ways of the Lord. Therefore from their ways shall the false prophet and the prophet be known. — The Didache, Chapter 11 Hilary of Arles : It is typical of false teachers that they cannot accept the full equality of the persons of the Trinity. — INTRODUCTORY COMMENTARY ON 2 PETER Hippolytus of Rome : And the apostles, who speak of God, in establishing the truth of the advent of the Lord Jesus Christ, have each of them indicated the appearing of these abominable and ruin-working men, and have openly announced their lawless deeds. First of all Peter, the rock of the faith, whom Christ our God called blessed, the teacher of the Church, the first disciple, he who has the keys of the kingdom, has instructed us to this effect: "Know this first, children, that there shall come in the last days scoffers, walking after their own lusts. And there shall be false teachers among you, who privily shall bring in damnable heresies." — Dubious Hippolytus Fragments Oecumenius : But there were also false prophets among the people, just as there will be false teachers among you, who secretly bring in destructive heresies, even denying the Lord who bought them, bringing upon themselves swift destruction. And many will follow their obscene ways, and because of them the way of truth will be blasphemed. And in their greed they will exploit you with false words. Their judgment from long ago is not idle, and their destruction is not asleep. Since prophecy is a common name that refers to both prophets and false prophets, it confirms that false prophets should not be regarded. And Paul differs slightly from this, as he teaches that no one says Jesus is Lord except by the Holy Spirit. (1 Cor. 12:3) Therefore, he begins to oppose the heresy against the Nicolaitans, saying that their wickedness is twofold. For they are indeed most impious in doctrine, as their blasphemy against the Lord Christ demonstrates; however, their life is especially obscene. And this he now signifies through shameful gain; however, having progressed a little, he will state it more openly. For now he refers to πλεονεξίαν, that is, greed, signifying shameful gain. For πλαονεξία sometimes signifies injustice, but at other times simply gain. Hence, showing that he speaks more particularly, he added: "they will exploit you." Completely alienating them from divine doctrine, he said they would use false words. But they will have, he says, the wages of impiety, namely death. Moreover, it is already an indication of the foreknowledge of God. For just as through foreknowledge He prepared good things for the good, so also a fitting place for the wicked. "who secretly," etc. The order: Those who, summoning swift destruction upon themselves, will secretly lead destructive sects; and denying the Lord who bought them, and through greed negotiating with false words about you. "is not asleep." He does not cease, nor will he be idle, sluggish, or ineffective. — Commentary on 2 Peter Tertullian : The character of the times in which we live is such as to call forth from us even this admonition, that we ought not to be astonished at the heresies (which abound) neither ought their existence to surprise us, for it was foretold that they should come to pass; nor the fact that they subvert the faith of some, for their final cause is, by affording a trial to faith, to give it also the opportunity of being "approved. — The Prescription Against Heretics
