2 Timothy 3.16-17

Book: 2 Timothy · NASB95

Verse

"All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work." (2 Timothy 3:16-17, NASB95)

Immediate context (±2 verses)

NASB95 (NASB95)

"You, however, continue in the things you have learned and become convinced of, knowing from whom you have learned them,"

"and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus."

"All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness;"

"so that the man of God may be adequate, equipped for every good work." (2 Timothy 3:14-17, NASB95)

Setting

Speaker: Paul, in his second Roman imprisonment c. AD 65-67, writing what is almost certainly his final letter before martyrdom under Nero (cf. 2 Tim 4:6 "the time of my departure has come").
Audience: Timothy, Paul's spiritual son and pastoral protégé, leading the church at Ephesus; the letter functions as Paul's pastoral testament charging Timothy with faithful preservation and transmission of the apostolic gospel.
Location: Paul writing from Rome (likely the Mamertine Prison); Timothy in Ephesus.
Time period: c. AD 65-67. Pauline corpus's last word on the doctrine of Scripture; functions as the load-bearing NT proof-text for the doctrine of biblical inspiration, and (paired with 2 Pet 1:20-21 + Heb 4:12 + Mt 5:17-18 + John 10:35) the foundational scriptural witness to its own divine origin.

Theological reading

1. Theopneustos, the hapax legomenon of inspiration

The word theopneustos (G2315, theos + pneō "God-breathed") is a NT hapax legomenon, appearing only here in the entire NT and rare in extra-biblical Greek. The compound is passive ("breathed-out by God"), denoting Scripture's origin in divine breath rather than human composition assisted by divine influence. The translation tradition reflects this: KJV "given by inspiration of God"; NASB "inspired by God"; ESV / NIV "breathed out by God" (the more literal recent rendering). The image is Genesis 2:7 (YHWH breathing into Adam) + Psalm 33:6 (the heavens made by the breath of His mouth), the same divine pneuma that gave life to Adam and made the heavens has produced Scripture.

Critically, theopneustos is in predicate position (pasa graphē theopneustos), "all Scripture is God-breathed", not attributive ("all God-breathed Scripture"). The translation matters: the predicate construction asserts that Scripture as such is divinely inspired, not that some Scripture among other writings is divinely inspired. (B. B. Warfield, The Inspiration and Authority of the Bible, 1948 ch. 4-5, settled this exegetical debate.)

2. Pasa graphē, "all Scripture"

In immediate context (v. 15 hiera grammata "sacred writings") pasa graphē refers to the OT canon Timothy knew "from childhood." Pauline-corpus graphē / graphai consistently denotes the OT (Rom 1:2, 4:3, 9:17, 10:11; 1 Cor 15:3-4 kata tas graphas; Gal 3:8, 22). However: 2 Pet 3:15-16 classifies Pauline letters as graphē, extending theopneustos to the apostolic writings; 1 Tim 5:18 cites Lk 10:7 alongside Deut 25:4 under the formula "Scripture says"; patristic + canonical reception applies the doctrine to the entire 66-book canon.

3. The four pastoral functions

Scripture's profitability is enumerated in four functional categories: didaskalia (teaching), elenchos (reproof / refutation), epanorthōsis (correction / setting-right), paideia tēn en dikaiosynē (training in righteousness). The four functions form a comprehensive pastoral arc: doctrine (positive teaching) → reproof (correcting error) → restoration (correcting practice) → ongoing-formation (sanctification). Verse 17's purpose-clause (hina artios ē ho tou theou anthrōpos, pros pan ergon agathon exērtismenos), "so that the man of God may be adequate, equipped for every good work", declares the scope: Scripture is sufficient for the full equipping of the believer. This is the load-bearing NT text for the Reformation doctrine of sola Scriptura + Scripture's material sufficiency (Westminster Confession 1.6: "the whole counsel of God concerning all things necessary for His own glory, man's salvation, faith, and life is either expressly set down in Scripture or by good and necessary consequence may be deduced from Scripture").

4. Apologetic load, the doctrine-of-Scripture anchor

The verse is the load-bearing NT proof-text for the Christian doctrine of biblical inspiration. The apologetic case is multi-pronged: (a) internal canonical self-witness (this verse + 2 Pet 1:20-21 + Mt 5:17-18 + John 10:35); (b) fulfilled prophecy (Isa 53; Mic 5:2; Dan 9:24-27; Ps 22; Zech 12:10); (c) historical-textual reliability (5,800+ Greek NT MSS; ~25,000 across all languages, the best-attested ancient text by orders of magnitude per Ehrman / Wallace / Metzger consensus); (d) archaeological corroboration (Hittites, Pontius Pilate, Caiaphas, Cyrus); (e) transformational-moral evidence. The Christian doctrine is plenary verbal inspiration (Scripture as a whole and in its words is God-breathed) preserving human authors' personalities + contexts (organic / concursive view per Warfield, Henry, Grudem).

5. Patristic + Reformation reception

Justin Martyr Dialogue with Trypho + First Apology (c. AD 155); Irenaeus Adv. Haer. II.28.2 + III.1.1 (apostolic Scripture as God-breathed); Origen On First Principles IV (treatise on Scripture's divine origin); Athanasius Festal Letter 39 (AD 367, first explicit 27-book NT canon list); Augustine Letter to Jerome 82.3: "I have learned to yield this respect and honor only to the canonical books of Scripture: of these alone do I most firmly believe that the authors were completely free from error"; Aquinas ST I q.1 a.10 (Scripture's divine authorship grounds multivalent literal + spiritual senses); Luther Preface to the NT (1522) + Bondage of the Will (1525), sola Scriptura programmatic; Calvin Inst. 1.7-9, the autopistos doctrine, testimonium Spiritus Sancti internum; Westminster Confession 1.4-6 (1646), canonical Reformed statement of plenary verbal inspiration + sufficiency. Modern: B. B. Warfield The Inspiration and Authority of the Bible (1948, magisterial theopneustos treatment); Carl F. H. Henry God, Revelation, and Authority (6 vols., 1976-1983); Chicago Statement on Biblical Inerrancy (1978); D. A. Carson + John Woodbridge Scripture and Truth (1983); Wayne Grudem Systematic Theology (1994) chs. 4-7; N. T. Wright Scripture and the Authority of God (2005); Kevin Vanhoozer The Drama of Doctrine (2005).

Key words (Greek)

theopneustos (G2315, theos "God" + pneō "to breathe / breathe-out"), NT hapax legomenon; passive compound denoting Scripture's origin in divine breath. The translation "God-breathed" (ESV / NIV) is more literal than "inspired" (KJV / NASB; inspirare = "breathe-into," weaker than theopneustos). Predicate construction (pasa graphē theopneustos) asserts Scripture-qua-Scripture is divinely-breathed, not that some-Scripture-among-others is.
graphē (G1124, "writing / Scripture"), Pauline-corpus consistent technical term for canonical-OT (Rom 1:2; 4:3; 9:17; 10:11; 1 Cor 15:3-4; Gal 3:8, 22). 2 Pet 3:15-16 extends the term to Pauline letters; canonical-reception applies it to the full canon.
artios (G739, "complete / fully suited") + exērtismenos (G1822 perfect-passive participle, "thoroughly equipped"), paired adequacy-and-equipping vocabulary; verse 17's purpose-clause grammar denotes Scripture's material sufficiency for the believer's full pastoral equipping.
paideia (G3809, "training / discipline / formation"), pedagogical-formation vocabulary; paideia tēn en dikaiosynē = "training in righteousness," signaling Scripture's role in ongoing-sanctification, not merely doctrinal-instruction.
