2 Peter 3:1

For ἤδη with numeral, cf. John 21:14. δευτέραν ἐπιστολήν. Does this refer to 1 Peter? See Introduction, p. 113. ἐν αἷς : “in both of which,” constructio ad sensum. διεγείρς … ὑπομνήσει : cf. 2 Peter 1:13.

εἰλικρινῆ : cf. 1 Corinthians 5:8 2 Corinthians 1:12; 2 Corinthians 2:17; Philippians 1:10. εἰλικρινῆ διάνοιαν is a technical philosophic term used by Plato. Phaed. 66 A = “pure reason,” such as the geometer employs. In Phaed. 81 C, εἰλικρινὴς ψυχή is opposed to ψ. μεμιασμένη καὶ ἀκάθαρτος. 2 Peter here cannot be acquitted of a confusion in the use of philosophic terms, probably picked up loosely in conversation. At the same time, διάνοια is also used in the philosophic sense of ψυχή in Genesis 17:17; Deuteronomy 6:5; Numbers 15:39; also in N.T. Coloss. 2Pe 1:21, 1 Peter 1:13. εἰλικρινής is of doubtful etymology, and signilies ethical purity, a mind uncontaminated and unwarped by sensual passion. The opposite state is described in Plato, Phaed. 81, “She thinks nothing true, but what is bodily, and can be touched and seen, and eaten and drunk, and used for men's lusts”.
