"God-breathed" — the term Paul uses to describe the nature of all Scripture (2 Tim. 3:16). Theopneustos affirms that the Bible is not merely a human book about God, nor a record of human spiritual impressions — it is the very breath of God expressed in written words. As God breathed life into Adam and Adam became a living being, God breathed His very words into the writers of Scripture, producing a text that is simultaneously fully human and fully divine. This is the bedrock of biblical authority: Scripture carries the weight and reliability of God's own character.
"Theopneustos" was not an English dictionary entry in Webster's era. However, the doctrine it encodes is foundational: Webster himself acknowledged the divine inspiration of Scripture as axiomatic to all true learning. The concept behind the term — that God supernaturally directed the human authors of Scripture to produce an inerrant text — was the unanimous consensus of the church for 1,800 years before modern criticism challenged it.
Modern scholarship routinely redefines "inspiration" to mean that the authors were spiritually elevated or emotionally moved — as a poet might be "inspired" — while remaining fully autonomous and fallible. This reduces Scripture to human literature containing religious wisdom, not the inerrant Word of God. The result is a Bible that can be corrected, edited, and overruled by human scholarship, cultural consensus, or personal experience. Once theopneustos is abandoned, Scripture loses its authority and the church loses its anchor. Every heresy in church history has required loosening the grip on a God-breathed, fully reliable Scripture.
2 Timothy 3:16–17 — "All Scripture is breathed out by God [theopneustos] and profitable for teaching, for reproof, for correction, and for training in righteousness."
2 Peter 1:21 — "Men spoke from God as they were carried along by the Holy Spirit."
Psalm 12:6 — "The words of the LORD are pure words, like silver refined in a furnace on the ground, purified seven times."
Matthew 5:18 — "Until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished."
G2315 — θεόπνευστος (theopneustos) — God-breathed; appears only in 2 Tim. 3:16; the foundational term for verbal plenary inspiration.
G4151 — πνεῦμα (pneuma) — spirit, breath, wind; the root of the second element; connects inspiration to the Holy Spirit's breathing forth of God's words.
Theopneustos is not the description of an experience the authors had — it describes the nature of the text they produced: breathed out by God, therefore authoritative, inerrant, and sufficient.
To say Scripture is theopneustos is to say it has the same reliability as God's own speech — "Heaven and earth will pass away, but My words will not pass away" (Matt. 24:35).
Theopneustos grounds the sufficiency of Scripture: since it is God's own breath, it lacks nothing necessary for "teaching, reproof, correction, and training in righteousness."
