καιρός

fitting season, opportunity, time

Definition

Kairos refers to a specific, appointed, or opportune time rather than just chronological duration (chronos). It often denotes a decisive moment ordained by God, such as the 'appointed time' for harvest (Matthew 13:30) or the 'time' of Jesus's ministry and judgment (Matthew 8:29, 26:18). In a more general sense, it can mean a fitting season or opportunity for action, as seen when the Pharisees look for the 'right time' to arrest Jesus (Matthew 26:16). The word carries a sense of qualitative, significant timing, especially when related to God's salvific plan.

Biblical Usage

Kairos appears throughout the New Testament, with significant concentration in the Gospels and Paul's letters. It frequently describes divinely appointed moments in salvation history, like 'the time is fulfilled' in Mark 1:15. Paul uses it for the present opportunity for salvation (2 Corinthians 6:2) and the future 'day of salvation.' It also appears in eschatological contexts about the 'end times' (Revelation 1:3) and in practical wisdom about recognizing the 'right time' for things (Matthew 16:3).

Etymology

Derived from the ancient Greek word καιρός (kairos), its root meaning relates to a decisive or critical point. Unlike chronos (sequential time), kairos implies a moment of opportunity, a fitting season, or a due measure. This qualitative sense developed in Koine Greek to emphasize appointed, significant times, which deeply influenced its theological use in the New Testament.

Semantic Range

Kairos is theologically crucial as it highlights God's sovereignty over time and history. It distinguishes human chronological time from God's appointed, purposeful moments—especially the 'fullness of time' in Christ (Galatians 4:4). Understanding kairos enriches reading by revealing how the New Testament presents Jesus's life, death, and resurrection as the definitive kairos, the opportune time for salvation and judgment, calling for a decisive human response.

In ancient Greek thought, kairos was a key concept in rhetoric, athletics, and medicine, representing the 'right moment' for action or the 'critical juncture' in an illness. The New Testament adopts this cultural understanding but transforms it, applying it primarily to God's timing within His redemptive narrative, contrasting with a purely human or philosophical sense of opportune moments.

χρόνος (chronos, G5550) — denotes chronological, sequential time or duration. ὥρα (hōra, G5610) — often refers to a specific hour or short period, sometimes overlapping with kairos but generally more precise. καιρός itself is distinct in emphasizing qualitative, appointed timing.
