Exploring the Meaning of Hieros in Greek

ἱερός expresses the idea of what is sacred. In the New Testament it appears in contexts that speak about temple service and about the Scriptures.

Occurrences

“Don’t you know that those who serve around sacred things eat from the things of the temple, and those who wait on the altar have their portion with the altar?” (1 Corinthians 9:13)

In this sentence the adjective marks certain “things” as belonging to a sphere set apart for worship. The setting is explicitly the temple and its altar: people “serve around sacred things,” and as they serve, they “eat from the things of the temple.” The word therefore functions to distinguish what is handled in that service from ordinary food or ordinary work. It identifies the objects or duties in view as connected with the temple’s cultic life, so that the following statements about eating and receiving a “portion” are framed as provisions tied to that sacred sphere. The line of thought depends on that designation: because the service is around what is sacred, the material support described (“eat,” “portion”) is portrayed as arising from, and belonging to, the same setting of temple and altar.

“From infancy, you have known the holy Scriptures which are able to make you wise for salvation through faith, which is in Christ Jesus.” (2 Timothy 3:15)

Here the adjective qualifies “Scriptures,” characterizing them as sacred. The verse places this sacred quality within a personal history: “From infancy, you have known the holy Scriptures.” The term does not merely label the writings but frames their role and effect in the life of the one addressed. Because the Scriptures are presented as sacred, their capacity is described in strong terms: they “are able to make you wise for salvation through faith, which is in Christ Jesus.” In this setting, the adjective sets the Scriptures apart as writings that carry religious weight and are treated as a formative authority from early life, linked in the sentence to wisdom and salvation through faith.

Sense and Usage

Across these two passages, ἱερός marks realities associated with the worship and instruction of God’s people as sacred. In 1 Corinthians 9:13, it is used within the concrete world of temple practice: sacred things stand in close proximity to “the things of the temple” and “the altar,” so the adjective underscores that the service described is not generic labor but service performed around what belongs to that worship environment. The word’s placement before “things” keeps the focus broad, allowing the statement to encompass the various items, duties, or provisions bound up with temple and altar, while still maintaining the key point that they are sacred.

In 2 Timothy 3:15, the term is attached not to temple objects but to a body of writings—“the holy Scriptures.” The sacred quality here is expressed in a way that connects to recognition and learning: the Scriptures are known “from infancy.” The verse then ties that sacred character to efficacy: these Scriptures are “able to make you wise for salvation through faith, which is in Christ Jesus.” The adjective thus functions as a cue for how these writings are to be regarded—set apart from ordinary texts—and, within the sentence itself, it supports the claim that they can shape a person toward wisdom with a view to salvation through faith.

Taken together, the two uses show the adjective operating in both ritual and textual domains without changing its basic force. In one, “sacred things” are connected with physical places and actions (temple, altar, eating, receiving a portion). In the other, “holy Scriptures” are connected with learning over time and with their ability to bring about wisdom in relation to salvation through faith. In both settings, the adjective signals that what it modifies belongs to a set-apart sphere and carries a weight appropriate to that sphere: temple service is described as service around sacred things, and Scripture is described as sacred writing with an effect that reaches into a person’s understanding and destiny.

Imagery

In 1 Corinthians 9:13, the word evokes the tangible world of temple service: people waiting on an altar, portions assigned, and food connected to worship. In 2 Timothy 3:15, it evokes the quieter image of sacred writings known from earliest years, yet portrayed as powerful—able to shape wisdom that leads toward salvation through faith in Christ Jesus.
