ἱερός

sacred, holy

Definition

The adjective ἱερός (hieros) fundamentally means 'sacred' or 'holy,' referring to that which is set apart for divine service or belongs to the sphere of the divine. In the New Testament, it is used specifically for things consecrated to God, such as the 'sacred things' of the temple (1 Corinthians 9:13). It also describes the 'sacred writings' (τὰ ἱερὰ γράμματα), meaning the Old Testament Scriptures, which are holy because they are God-breathed and able to instruct for salvation (2 Timothy 3:15). Unlike some other 'holy' words, ἱερός often carries a more formal, institutional sense of sacredness related to the temple and its rituals.

Biblical Usage

ἱερός is used only twice in the New Testament, both times by the Apostle Paul. In 1 Corinthians 9:13, it refers to the material 'sacred things' of the temple, supporting the principle that those who serve the altar share in its offerings. In 2 Timothy 3:15, it describes the 'sacred writings' Timothy learned from childhood, emphasizing the holy and divine origin of the Scriptures. Its usage is thus confined to contexts of temple service and the authoritative, set-apart nature of the biblical text.

Etymology

Derived from the ancient Greek root ἱερ- (hier-), relating to the gods, the divine, or power. It is the root for many words concerning priesthood and sacred rites, such as ἱερεύς (hiereus, 'priest') and ἱερόν (hieron, 'temple'). Its meaning consistently revolves around what is dedicated to or associated with the divine realm.

Semantic Range

This word is theologically significant as it connects the tangible, institutional holiness of the Old Covenant (the temple and its services) with the spiritual authority of Scripture. In 2 Timothy 3:15, it underscores the doctrine of the inspiration and sufficiency of the Old Testament, which points to Christ. Understanding ἱερός enriches reading by highlighting how the New Testament authors viewed the Old Testament not merely as ancient literature but as the sacred, God-given text that prepares us for faith.

In the Greco-Roman world, ἱερός was a common term for anything dedicated to a god—temples, sacrifices, or ritual objects. For Jewish and Christian writers, it was adopted to specifically describe the God of Israel's holy things and writings. The 'sacred writings' (2 Timothy 3:15) would have been understood by Timothy as the uniquely authoritative Jewish Scriptures, set apart from all other literature.

ἅγιος (hagios, G40) — Emphasizes moral and spiritual purity, being set apart for God; commonly used for believers and the Spirit. ὅσιος (hosios, G3741) — Focuses on piety, devotion, and what is pleasing to God, often in relation to His character or covenant faithfulness.
