Graphe (γραφή) means a writing or document, but in the New Testament it almost always refers specifically to the sacred Scriptures — the Old Testament writings understood as authoritative divine communication. It appears about 51 times and is the standard New Testament term for Scripture.
Graphe carries the weight of divine authority wherever it appears. Jesus frequently invokes it: 'Have you not read in the Scripture?' (Matthew 21:42); 'The Scripture cannot be broken' (John 10:35). Paul's foundational statement in 2 Timothy 3:16 — 'All Scripture [graphe] is God-breathed' — establishes the divine origin of the text. Peter confirms in 2 Peter 1:20 that no prophecy of graphe comes from private interpretation. In Luke 24:27, the risen Jesus 'beginning with Moses and all the Prophets, explained to them what was said in all the Scriptures [graphais] concerning himself.' All of Scripture points to Christ, and Christ fulfills all of Scripture.
