2 Peter 2:1

This term, composed of 'false' (pseudos) and 'teacher' (didaskalos), underscores the deceptive nature of their teaching. They are not merely mistaken, but intentionally distort the truth. Peter compares them to the 'false prophets' of the OT, indicating a continuity in the threat to God's people.

The prefix 'par-' suggests an introduction 'alongside' or 'in addition to' the truth, in a subtle and deceptive, not open, manner. This indicates that their heresies will not be obvious at first, but will gradually infiltrate the community, mixing with true teaching.

The term 'haireseis' (heresies) in this context does not refer to a simple difference of opinion, but to sectarian divisions that are 'of destruction' (apōleias), meaning they lead to spiritual ruin or perdition. This underscores the seriousness of their teaching and its eternal consequences.

This participle is the point of greatest interpretive tension. The verb agorazō (agorazō) means 'to buy' or 'to acquire in the marketplace,' often with the implication of freeing from slavery. In the NT, it is used for Christ's redemption (e.g., 1 Cor 6:20; 7:23; Rev 5:9). The question is whether it refers here to a full and effective saving redemption for these false teachers (which would imply that salvation can be lost), or to a 'buying' in a more general sense (e.g., liberation from the slavery of sin in an external sense, or a covenant relationship that is later broken), or even to a 'buying' that is only apparent to the community but not real in a saving sense. The text does not specify the exact nature of this 'buying' in relation to the final condition of the false teachers.

This term emphasizes Christ's authority and sovereignty. Denying this 'Lord' who 'bought' them is an act of rebellion against His authority and His redemptive work, whatever the precise nature of that 'buying'.

Patristic

The Church Fathers recognized the seriousness of apostasy and the existence of those who, having received some benefit or knowledge of Christ, later denied Him. Augustine of Hippo (354-430), in his work *On Rebuke and Grace* (*De correptione et gratia*, ch. 9, PL 44, cols. 925-926), distinguishes between those who receive external gifts of grace—including the sacraments and apparent faith—and those truly predestined who persevere to the end. For Augustine, it is possible for someone to participate in the mysteries of Christ and yet not belong to the number of the elect; their subsequent apostasy does not refute the perseverance of the saints but rather reveals that they were never fully incorporated into it. This perspective allows a reading of 'the Master who bought them' (2 Pet 2:1) that does not necessarily imply final and irreversible salvation for all so described. Cyprian of Carthage (c. 200-258), in his treatise *On the Lapsed* (*De lapsis*, PL 4, cols. 463-494), addresses the concrete case of those who, though baptized and members of the Church, denied Christ during the Decian persecution, repudiating by their actions the one who had redeemed them. Cyprian underscores the gravity of such betrayal precisely because these 'lapsed' had been sealed with the name of Christ and had shared in His benefits, making their denial all the more culpable—an observation in close resonance with the language of 2 Peter 2:1. Origen (c. 185-254), in his *Commentary on John* and his *Homilies on Ezekiel*, reflects on the possibility that those who have tasted spiritual gifts may subsequently fall away from the truth; however, his direct comments on 2 Peter 2:1 have not been preserved intact in the available Greek sources, and his general theology on apostasy is therefore invoked as an interpretive framework rather than as direct exegesis of the verse.

Reformed

The Reformed tradition, especially Calvinist, interprets 'the Lord who bought them' in several ways to maintain the doctrine of limited atonement and the perseverance of the saints. A common reading is that the 'buying' (ἀγοράσαντα) refers to a redemption in a general or external sense, such as liberation from the slavery of sin or participation in the covenant community, but not an effective saving redemption that guarantees final salvation. Another interpretation is that these false teachers were never truly 'bought' in the sense of having received regenerating salvation, but only professed faith or had a superficial experience. John Calvin, in his *Commentary on 2 Peter*, suggests that 'bought' can refer to the redemption Christ accomplished for humanity in general, or that the false teachers had 'sold themselves' to Christ in some external way, but not internally.

Interpretive tension: Interpretive tension within the Reformed system arises when reconciling the affirmation that Christ 'bought' these individuals with the doctrine of limited atonement (that Christ died effectively only for the elect) and the perseverance of the saints (that true believers cannot lose their salvation). It requires a careful distinction between different types of 'buying' or a redefinition of the spiritual condition of the false teachers that the text does not explicitly state.

Arminian

The Arminian tradition interprets 'the Lord who bought them' as a reference to Christ's universal atonement, where He died for all human beings, making salvation possible for everyone. In this reading, the false teachers were genuinely 'bought' or redeemed by Christ, but then, by their own will, denied the Lord and fell from grace, losing their salvation. This interpretation supports the doctrine of apostasy, i.e., the possibility for a true believer to fall away from faith and be lost. John Wesley and other Arminian theologians emphasize human responsibility in maintaining faith and the possibility of rejecting God's saving grace.

Interpretive tension: Interpretive tension within the Arminian system arises when reconciling the possibility of apostasy with the assurance of salvation found in other biblical passages (e.g., John 10:28-29, Romans 8:38-39). It requires an explanation of how God's sovereignty and His saving purpose can be thwarted by human decision, which the text does not explicitly state either.

Contemporary

Richard Bauckham, in his commentary on 2 Peter and Jude, argues that 'agorasantas' refers to Christ's redemption that is offered to all, and that the false teachers are those who have experienced this redemption in some sense (perhaps a liberation from the slavery of sin or a participation in the Christian community) but then reject it. Peter H. Davids suggests that the language of 'buying' may refer to the liberation from the power of sin and death that Christ accomplished for all, and that the false teachers are those who have 'escaped the pollutions of the world' (2 Peter 2:20) but then become entangled again. Most contemporary commentators acknowledge the difficulty of the term and the tension it generates for both theological systems, often opting to describe the phenomenon without resolving the systematic tension.
