Porque mejor les hubiera sido no haber conocido el camino de la justicia, que después de haberlo conocido, tornarse atrás del|strong="G1537, G3588" santo mandamiento que les fué dado.
Porque melhor teria lhes sido se não tivessem conhecido o caminho da justiça do que, depois de conhecerem, terem se desviado do santo mandamento que havia lhes sido entregue.
Car mieux valait pour eux n’ avoir pas connu la voie de la justice, que de se détourner, après l’ avoir connue, du saint commandement qui leur avait été donné.
Denn es wäre ihnen besser, daß sie den Weg der Gerechtigkeit nicht erkannt hätten, als daß sie erkennen und sich kehren von dem heiligen Gebot, das ihnen gegeben ist.
Want het ware hun beter, dat zij den weg der gerechtigheid niet gekend hadden, dan dat zij, dien gekend hebbende, weder afkeren van het heilige gebod, dat hun overgegeven was.
Perché meglio sarebbe stato per loro non aver conosciuta la via della giustizia, che, dopo averla conosciuta, voltar le spalle al santo comandamento ch’era loro stato dato.
Bo by im było lepiej, nie uznać drogi sprawiedliwości, niżeli poznawszy ją, odwrócić się od podanego im rozkazania świętego.
Лучше бы им не познать пути правды, нежели, познав, возвратиться назад от преданной им святой заповеди.
他們 曉得 義 路，竟背棄了 傳給 他們 的聖 命， 倒不如 不 曉得 為妙。
For it would have been better for them to have had no knowledge of the way of righteousness, than to go back again from the holy law which was given to them, after having knowledge of it.

Scholars' Consensus
Commentators across traditions agree that this verse does not make ignorance desirable. Instead, it uses a sharp comparison to underline the horror of apostasy. Barnes notes three reasons the turning back is worse: the cause of religion is dishonored, the sinner sinks deeper into corruption, and condemnation is more severe. Clarke adds that those who sin after receiving mercy are capable of more sin and liable to greater punishment. Calvin calls them “inexcusable” for forsaking the holy commandment after having known it. The Greek verb for “known” (epegnōkenai) is the perfect infinitive, implying thorough, settled knowledge (Cambridge Bible). The “way of righteousness” is not a bare doctrine but the whole Christian life seen in its moral shape (Jamieson-Fausset-Brown). What seems a puzzle in the English is a deliberate rhetorical heightening: the point is not that ignorance is good, but that apostasy is so catastrophic that never having known at all would have spared them the added weight of guilt.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Perseverance of the saints view (Calvinist): The apostates had merely notional knowledge, not saving faith; the truly elect cannot fall away.
- Possibility of apostasy view (Arminian): Those who had genuine knowledge and salvation can turn away and forfeit their salvation; this verse warns them.
What is clear: Turning from known truth after once embracing it brings greater condemnation than never having known it.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Whether the apostates were truly saved | All Christians agree that turning from known truth is a grave sin with serious consequences. | Calvinists see these as professing but unsaved (since they never had saving faith), while Arminians and others see them as genuine believers who lost their salvation. Both sides agree the warning is real. |
| Meaning of 'holy commandment' | It refers to the moral and doctrinal teaching of the gospel, especially its call to holiness. | Some see it primarily as the law of love (Clarke), while others see it as the whole deposit of faith (Gill, JFB). |
| The purpose of the hyperbole | The verse is not a justification of ignorance but a rhetorical intensification of apostasy's seriousness. | Some emphasize the pedagogical value (to deter), while others focus on the judicial principle (greater light, greater guilt). |
| The 'way of righteousness' definition | It describes the Christian life, including both justification and sanctification. | Gill emphasizes the doctrine of justification by faith; others like the Cambridge Bible stress the ethical path of holiness. |
| Implication for pastoral care | Warnings against apostasy are necessary for the health of the church. | Pastors disagree on how to apply this to those who have left the faith: should they hold out hope for return or pronounce judgment? |
Historical & Cultural Context
This verse stands within Peter’s fierce denunciation of false teachers who had infiltrated the churches of Asia Minor (2 Peter 2:1, 3). These teachers used “great swelling words of emptiness” to entice believers back into “the lusts of the flesh” (v. 18). Verse 20 declares that those who escaped the world’s defilements through knowledge of Christ, only to be caught again, end up worse than before. Verse 21 explains why: knowing the way of righteousness and then turning from the holy commandment is more grievous than never knowing it at all.
The “way of righteousness” is a phrase drawn from the Old Testament (Proverbs 12:28; 16:31) and early Christian idiom (Acts 9:2, 19:9, 23). It describes the whole pattern of Christian faith and ethics, the path of right relation with God and neighbor. The “holy commandment” probably refers to the gospel’s moral teaching, especially the law of love (Clarke), or to the entire Christian revelation (Gill, JFB). The verb “delivered” (paradotheisēs) is technical: it means handing down apostolic tradition (1 Corinthians 11:23, 15:3; Jude 3). This tradition was given “once for all” (JFB), not to be revised or abandoned.
In the first-century Mediterranean world, conversion was costly. Turning back would bring shame on the church, confirm pagan suspicions, and worst of all, heap guilt on the apostate. Peter uses the strongest possible language, hyperbole of the “better never to have known”, to shake his readers free from complacency. He is not saying ignorance is bliss; he is warning that knowledge brings responsibility, and that willful rejection of known truth deepens condemnation. The following verse (v. 22) pictures the apostates as dogs returning to their vomit, stressing that their relapse reveals their true nature.
Textual Notes
The only variant mentioned in the supplied sources is between ὑποστρέψαι (to turn back) and ἐπιστρέψαι (to turn) in some manuscripts. The reading adopted in the critical texts (NA28/UBS5) is ὑποστρέψαι, which emphasizes the idea of turning back to a previous state. No major theological differences result from this variant.
Reception History
The church father John Chrysostom took this verse as a caution against sinning after forgiveness: “Do not sin after forgiveness; do not suffer yourself to be wounded after your healing.” Throughout church history, this verse has been used to warn believers against backsliding. In the Reformation, both Catholic and Protestant teachers appealed to it when discussing the possibility of falling from grace. It continues to serve as a sober check on complacency, reminding the church that knowing the truth brings both privilege and responsibility.
Preaching This Verse
Three-point outline
- Knowledge without perseverance is dangerous. Knowing the way of righteousness is a privilege, but it carries weight. The false teachers had thorough, acknowledged knowledge (epegnōkenai) and still turned back. Intellectual assent without ongoing trust leaves a person vulnerable to greater sin.
- Apostasy is worse than ignorance. The hyperbole of verse 21 does not make ignorance good. It shows that the judgment of those who deliberately reject known truth is more severe. Every step away from the light makes the darkness deeper.
- The holy commandment calls for holiness. The “commandment delivered” is the deposit of apostolic teaching, and it is “holy.” To abandon it is to reject not just a code but the God who gave it. Peter calls his readers to stand firm in what they received.
Five-point outline
- Knowledge: a blessing and a burden. To know the way of righteousness is to receive God’s revelation. That knowledge demands a response of obedience.
- Turning back: a willful choice. The verb “turn back” (hupostrepsai) implies returning to a former state. These are not passive drifters; they have actively reversed direction.
- Greater guilt, greater judgment. The comparative “better” shows degrees of accountability. Those with more light are more responsible.
- The holy commandment: a sacred trust. The teaching of Christ has been “delivered” to the church in a once-for-all act. It is holy because of its origin, content, and purpose; to trample it is sacrilege.
- Warning for the whole church. Peter does not target the false teachers alone. The surrounding verses address the whole congregation (2:20, 3:1, 2). Every believer must guard against backsliding and hold fast to the truth.
Illustration hooks
- A recovered patient who deliberately returns to a harmful habit. After months of treatment and healing, the relapse is more damaging than the original condition. The knowledge of health makes the return worse.
- A public figure who renounces Christianity. Someone who once confessed Christ, taught the faith, or led others, then turns away. The harm to others and the weight of personal responsibility are far greater than if they had never made a profession.
- An athlete who trains for years and then throws away a final competition through disqualification. The talent and preparation were real, but a single choice wasted everything. The regret is deeper than if they had never begun.
Questions your congregation is asking
- “Does this verse mean that some people who genuinely know Jesus can lose their salvation?”
- “I have struggled with the same sin for years. Am I turning back from the holy commandment?”
- “How do I respond to a friend or family member who has left the faith after being raised in it?”
Leading a Discussion
This verse confronts us with a sobering truth: knowing God’s way brings responsibility. The false teachers of 2 Peter 2 had knowledge and professed Christianity, yet they turned back. The passage asks us to examine our own hold on the faith and to encourage one another to persevere.
Discussion questions
- What stands out to you in this verse? (Observation)
- The Greek uses a perfect infinitive for “have known”, thorough knowledge. Why is that detail important? (Interpretation)
- Barnes says it would be better for those who turn away “not to have known” because they dishonor religion and face worse punishment. Do you agree? What do you make of this strong language? (Interpretation)
- What is “the way of righteousness”? How is it different from just knowing facts about Christianity? (Interpretation)
- This verse is a warning, but how might it also be a comfort for believers who are struggling but have not turned away? (Application)
- Peter uses the analogy of a dog returning to its vomit in the next verse. What does that say about human nature and the need for grace? (Application)
- How can your small group help each other “stand firm” in the holy commandment? (Application)

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke defines the holy commandment as the whole religion of Christ, summed up in loving God and neighbor. He insists that through Christ's grace, every person can obey this command, and that such obedience keeps one from all sin against God or neighbor.
Barnes' Notes on the Bible Protestant 1832
Barnes gives three specific reasons it would have been worse for those who turn from the faith: they dishonor religion, fall deeper into sin, and face harsher judgment. His point is that if people are set on being wicked, they should never pretend to be good, because apostasy brings a more severe fate.
Calvin's Commentaries Reformed 1564
Calvin argues that falling away from the gospel means making oneself a slave again to sin, and such people are without excuse. Believers do sin, but because they strenuously resist the flesh and refuse to let sin rule, they do not fall away. For Calvin, returning to former pollutions shows that the gospel's teaching has been renounced.
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge Bible commentary stresses that "known" here means the deepest, fullest form of knowledge, not mere awareness. The focus falls on ethical failure: turning from the holy commandment delivered through oral teaching before baptism. The writer treats this as departure from righteous living rather than from correct doctrine.
Geneva Bible Notes Reformed 1599
The Geneva annotator argues that knowing the way of righteousness and then abandoning it makes a person's state worse than if they had never known it at all. Willful rejection after clear knowledge brings greater condemnation than simple ignorance ever could.
Gill's Exposition of the Bible Baptist 1748
Gill argues that knowing the Gospel and then turning from it makes a person far worse off than never knowing it at all. Their guilt and punishment are greater because they had clear light about justification through Christ's righteousness, yet rejected it. For him, proportionate to light received is the severity of judgment.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB emphasizes that the holy commandment of the Gospel is not about making believers holy but about a standard that must be kept inviolate. The word delivered means the faith was given once for all, leaving no room for turning back. The warning against turning away underscores the irreversible seriousness of abandoning Christian truth.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry highlights the stark contrast between false teachers and even the angels, who show restraint. These teachers, by contrast, act like brute beasts, driven by corrupt desires and speaking arrogantly against what they do not understand. Their certain destruction is made worse by their having known the way of righteousness and then turning from it.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley observes that the commandment refers to God's entire law, which was originally inscribed on human hearts, not merely spoken to their ears. His point is that the law's first and proper home is the inner person, not just external instruction.
