Footnotes:

1. 1:1 Symeon Peter: on the authorship of 2 Peter, see Introduction; on the spelling here of the Hebrew name Šim‘ôn, cf. Acts 15:14. The greeting is especially similar to those in 1 Peter and Jude. The words translated our God and savior Jesus Christ could also be rendered “our God and the savior Jesus Christ”; cf. 2 Pt 1:11; 2:20; 3:2, 18.
2. 1:2 Knowledge: a key term in the letter (2 Pt 1:3, 8; 2:20; 3:18), perhaps used as a Christian emphasis against gnostic claims.
3. 1:3–4 Christian life in its fullness is a gift of divine power effecting a knowledge of Christ and the bestowal of divine promises (2 Pt 3:4, 9). To share in the divine nature, escaping from a corrupt world, is a thought found elsewhere in the Bible but expressed only here in such Hellenistic terms, since it is said to be accomplished through knowledge (2 Pt 1:3); cf. 2 Pt 1:2; 2:20; but see also Jn 15:4; 17:22–23; Rom 8:14–17; Hb 3:14; 1 Jn 1:3; 3:2.
4. 1:3 By his own glory and power: the most ancient papyrus and the best codex read “through glory and power.”
5. 1:5–9 Note the climactic gradation of qualities (2 Pt 1:5–7), beginning with faith and leading to the fullness of Christian life, which is love; cf. Rom 5:3–4; Gal 5:6, 22 for a similar series of “virtues,” though the program and sense here are different than in Paul. The fruit of these is knowledge of Christ (2 Pt 1:8) referred to in 2 Pt 1:3; their absence is spiritual blindness (2 Pt 1:9).
6. 1:10–11 Perseverance in the Christian vocation is the best preventative against losing it and the safest provision for attaining its goal, the kingdom. Kingdom of…Christ, instead of “God,” is unusual; cf. Col 1:13 and Mt 13:41, as well as the righteousness of…Christ (2 Pt 1:1).
7. 1:12–19 The purpose in writing is to call to mind the apostle’s witness to the truth, even as he faces the end of his life (2 Pt 1:12–15), his eyewitness testimony to Christ (1 Pt 1:16–18), and the true prophetic message (2 Pt 1:19) through the Spirit in scripture (2 Pt 1:20–21), in contrast to what false teachers are setting forth (2 Pt 2).
8. 1:13 Tent: a biblical image for transitory human life (Is 38:12), here combined with a verb that suggests not folding or packing up a tent but its being discarded in death (cf. 2 Cor 5:1–4).
9. 1:16 Coming: in Greek parousia, used at 2 Pt 3:4, 12 of the second coming of Christ. The word was used in the extrabiblical writings for the visitation of someone in authority; in Greek cult and Hellenistic Judaism it was used for the manifestation of the divine presence. That the apostles made known has been interpreted to refer to Jesus’ transfiguration (2 Pt 1:17) or to his entire first coming or to his future coming in power (2 Pt 3).
10. 1:17 The author assures the readers of the reliability of the apostolic message (including Jesus’ power, glory, and coming; cf. note on 2 Pt 1:16) by appeal to the transfiguration of Jesus in glory (cf. Mt 17:1–8 and parallels) and by appeal to the prophetic message (2 Pt 1:19; perhaps Nm 24:17). Here, as elsewhere, the New Testament insists on continued reminders as necessary to preserve the historical facts about Jesus and the truths of the faith; cf. 2 Pt 3:1–2; 1 Cor 11:2; 15:1–3. My Son, my beloved: or, “my beloved Son.”
11. 1:18 We: at Jesus’ transfiguration, referring to Peter, James, and John (Mt 17:1).
12. 1:20–21 Often cited, along with 2 Tm 3:16, on the “inspiration” of scripture or against private interpretation, these verses in context are directed against the false teachers of 2 Pt 2 and clever tales (2 Pt 1:16). The prophetic word in scripture comes admittedly through human beings (2 Pt 1:21), but moved by the holy Spirit, not from their own interpretation, and is a matter of what the author and Spirit intended, not the personal interpretation of false teachers. Instead of under the influence of God, some manuscripts read “holy ones of God.”
