Scripture as Ultimate Authority in Teaching and Practice
The Biblical Foundation
The New Testament explicitly grounds Christian authority in Scripture's divine origin. Paul writes that "all Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness" [2]. The Greek term underlying "inspired" is theopneustos, meaning "breathed out by God" [6]—not merely human insight elevated by divine influence, but words whose origin is God himself. This claim extends to the entire corpus: "every Scripture" in its constituent parts bears this character [8]. The Holy Spirit's role in producing Scripture is equally emphasized, with Peter affirming that "holy men of God spoke as they were moved by the Holy Spirit" [3], making the Spirit's agency inseparable from the text's authority.
Authority in Doctrine and Practice
Early Christian interpretation consistently identified Scripture as "the true source of all authority in questions of doctrine and practice" [5]. This principle rests on Scripture's character as "the Word of God" [1], a designation Christ himself validated by appealing to written revelation during temptation and controversy [1]. The apostolic pattern reinforced this: Christ "taught out of" Scripture [1], and the early church measured all teaching against the written standard. The claim is not that Scripture contains wisdom among other sources, but that it functions as the definitive norm—what one tradition calls "the infallible guide of men, and is perfectly trustworthy in all its parts, as given by God" [4].
Purity and Sufficiency
The biblical witness describes Scripture as inherently pure, "free from all falsehood and error; coming from the God of truth, who cannot lie" [7]. This purity extends to every promise and precept, rendering Scripture self-authenticating in its truthfulness. The Spirit's role continues beyond inspiration: Jesus promised that the Spirit would "teach you all things, and bring all to remembrance" [9], establishing the basis for apostolic testimony and the Gospel accounts' reliability. The Spirit's work ensures not only the original production of Scripture but its ongoing clarity and power in the community of faith.
The Reformation crystallized this principle in the doctrine of sola scriptura, though the concept itself derives from the New Testament's own self-testimony. Scripture's ultimacy does not negate tradition or reason but subordinates them to the written Word as the final arbiter. Where human teaching conflicts with Scripture, the text itself judges the teaching—a principle embedded in the apostolic exhortation to test all claims against revealed truth.

Without deciding on any of the various theories of inspiration, the general doctrine of Christians is that the Bible is so inspired by God that it is the infallible guide of men, and is perfectly trustworthy in all its parts, as given by God.”

Paul was speaking of the Hebrew Scriptures (the Old Testament), but his statement can now apply to all Scripture, including the New Testament (see, e.g., 2 Pet 3:15-16). 3:16 The fact that Scripture is inspired by God (literally God-breathed, breathed out by God’s own speech; see also Heb 4:12-13; 2 Pet 1:20-21) does not negate the active involvement of the human authors.

However, English Version is sustained, though the Greek article be wanting, by the technical use of the term "Scripture" being so well known as not to need the article (compare Greek, Eph 3:15; Eph 2:21). The Greek is never used of writings in general, but only of the sacred Scriptures. The position of the two Greek adjectives closely united by "and," forbids our taking the one as an epithet, the other as predicated and translated as ALFORD and ELLICOTT. "Every Scripture ”
