ΚΑΙΡΟΣ

LEXARITHMOS 401

Kairos (καιρός, ὁ) is the ancient Greek concept of the “right, opportune, or critical moment,” distinct from Chronos (χρόνος, ὁ), which refers to linear, quantitative time. It is not merely a point in time, but a decisive juncture, an opportunity to be seized, a moment of decision or crisis. Its lexarithmos (401) suggests the fullness and perfection of the appropriate moment.

Definition

According to the Liddell-Scott-Jones Lexicon, *kairos* is primarily defined as “the right or opportune time, occasion, critical moment, season.” This word is fundamentally distinguished from *chronos*, which denotes the continuous, linear flow of time. *Kairos*, in contrast, is qualitative: it is the moment that “counts,” the decisive turning point, the opportunity that presents itself and demands action.

In classical thought, *kairos* was closely linked to art and rhetoric. Sophists like Gorgias emphasized the importance of *kairos* in persuasion, arguing that effective speech depended on the orator's ability to adapt their message to the specific occasion. Plato and Aristotle extended the concept into ethics and politics, where *kairos* signifies the “mean,” the appropriate proportion, and the fitting moment for the execution of an action.

During the Hellenistic and Roman periods, the concept of *kairos* retained its meaning of opportunity and fate. In the Septuagint, *kairos* is frequently used to translate the Hebrew word `עֵת` (et), denoting “God's time,” the appointed moment for divine intervention. In the New Testament, *kairos* acquires an eschatological dimension, referring to the “fullness of time” for the advent of Christ and the establishment of the Kingdom of God, as well as the urgent need for repentance and action.

Etymology

kairos ← possibly from the root *ker- (as in keirō)
The etymology of *kairos* is a subject of debate. A widely accepted theory connects it to the root *ker- (as in the verb κείρω, “to cut, to sever, to divide”), suggesting a “cut-off” or “separated” moment. This connection reinforces the idea of *kairos* as a distinct, decisive point in time, one “cut out” from the continuous flow of *chronos*. Other proposals include a link to the verb καίω (“to burn, to kindle”), suggesting a moment of intensity or culmination, though this connection is less linguistically probable.

Related words include the verb κείρω (“to cut, to shear”), the noun κάρτος (“strength, power, opportunity”), and the adjective καιρίος (“opportune, critical, decisive”). The notion of “cutting” or “division” is central to these cognates, underscoring the idea of a determined or separated point.
