Exploring the Meaning of Teleios in Greek

τελείως means “completely.” It appears once in the Greek Scriptures, in an exhortation that calls for alertness and undivided hope in view of the revelation of Jesus Christ.

Root and Related Words

τελείως is derived from teleios (τέλειος), “perfect” (Strong’s G5046).

Occurrences

“Therefore prepare your minds for action. Be sober, and set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ—” (1 Peter 1:13)

In this line of exhortation, τελείως sharpens the command about hope by pressing it toward an undivided, thoroughgoing orientation. The surrounding imperatives form a tight chain: “prepare your minds for action,” “be sober,” and then “set your hope” in a way that is described as full. Within this sequence, the adverb functions as a qualifier of the manner and extent of hoping: hope is not to be partial, intermittent, or shared out among competing objects, but directed with completeness toward “the grace that will be brought to you.”

The immediate context in the verse also shows how this completeness is meant to operate. The command is not merely inward or emotional; it is coupled to mental readiness (“prepare your minds for action”) and clear-headed vigilance (“be sober”). τελείως, placed with the instruction to “set your hope fully,” gathers these dispositions into a single, integrated stance: a mind readied for action and a sober posture are to culminate in a hope that is carried through without remainder toward its stated object.

The verse anchors that object in time and event: “the grace that will be brought to you at the revelation of Jesus Christ.” τελείως therefore also gives the hope a kind of horizon. The completeness of hope is not defined here by intensity alone, but by its total reference to what is promised “at the revelation of Jesus Christ.” The adverb helps keep the command from being treated as vague optimism; it binds hope to the coming disclosure named in the verse, calling for a hope that goes the whole way to that promised arrival.

Sense and Usage

The definition “completely” fits the way τελείως operates as an adverb of extent: it pushes an action to be carried out in a full measure rather than a limited one. In 1 Peter 1:13, the modified action is not a physical task but the directed posture of “set your hope,” and the adverb’s force is to exclude a divided or fractional hope. The completeness it conveys is practical and moral in tone, because it sits within a cluster of commands that regulate attention, judgment, and readiness.

Within this single attestation, the word’s contribution can be observed in how it shapes the relationship between the reader’s present discipline and the promised future gift. The verse names concrete present activities—mental preparation and sobriety—then points the reader to a future bestowal: “the grace that will be brought to you.” τελείως links the present to the future by insisting that hope be set without reserve on that coming grace. The completeness is thus not abstract; it is tied to the way the will fixes itself on a specified promise.

The placement of τελείως also reinforces the exclusivity of the object named. The verse does not call for hoping in general; it specifies “the grace that will be brought to you,” and then further specifies the moment when it will be brought: “at the revelation of Jesus Christ.” By urging hope to be set “fully,” the adverb pushes the reader to let that future grace define the entire scope of expectation. Completeness here is the opposite of leaving some portion of hope unanchored or placed elsewhere; it is the verbal pressure that makes “set your hope” total in its reach.

Finally, τελείως works in concert with the verse’s sober, action-ready posture. “Prepare your minds for action” implies a mind gathered up rather than scattered; “be sober” implies judgment unclouded rather than dulled. The adverb matches these qualities by requiring hope that is likewise gathered up—complete, not dissipated. In this way, “completely” is not an isolated emphasis but part of a coherent exhortation in which mental readiness, sobriety, and full hope mutually interpret one another.

Imagery

The verse’s imagery is that of readiness and orientation: a mind “prepared…for action,” a sober stance, and hope set forward toward an approaching disclosure. τελείως adds the sense of an unbroken line of expectation reaching all the way to “the revelation of Jesus Christ,” so that hope is pictured as fully extended toward the promised grace rather than held back or split.
