κριτικός

able to judge

Definition

The adjective κριτικός describes something or someone that is 'able to judge,' 'discerning,' or 'critical' in the sense of making a penetrating evaluation. In its sole New Testament occurrence, it characterizes the word of God as 'sharper than any double-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning (κριτικός) the thoughts and intentions of the heart' (Hebrews 4:12). Here, it conveys the active, penetrating power of God's word to sift, evaluate, and reveal the deepest, most hidden realities of the human person. It goes beyond simple observation to imply a definitive, authoritative judgment that exposes truth.

Biblical Usage

This word is used only once in the New Testament, in Hebrews 4:12. It is used to describe the inherent, active quality of the 'word of God' (λόγος τοῦ θεοῦ). The context is a warning against unbelief and a call to enter God's rest, emphasizing that nothing is hidden from God's penetrating revelation. The usage is highly theological and metaphorical, attributing a human faculty (critical judgment) to the divine message itself.

Etymology

Derived from the verb κρίνω (krinō, G2919), meaning 'to judge, decide, separate, or distinguish.' The suffix -τικός (-tikos) forms an adjective meaning 'pertaining to' or 'able to' the action of the root verb. Thus, κριτικός literally means 'pertaining to judging' or 'having the ability to judge.' It is the source of the English word 'critical.'

Semantic Range

This word is theologically significant as it attributes a divine, active power of judgment and revelation to Scripture itself. It underscores the doctrine of the efficacy and sufficiency of God's word, which is not inert but actively works to convict, reveal, and transform the believer (Hebrews 4:12-13). Understanding this Greek term enriches reading by highlighting that God's word is not just informative but performative—it critically assesses and exposes the human heart before God.

In ancient Greek culture, the term was used in rhetoric, philosophy, and medicine to describe the skill of making fine distinctions or accurate diagnoses. The author of Hebrews uses this culturally understood concept of precise, analytical judgment and applies it supremely to the divine word, elevating it beyond human critique to the level of ultimate spiritual reality.

κρίνω (krinō, G2919) — the root verb meaning 'to judge, decide, separate.' διακρίνω (diakrinō, G1252) — to make a distinction, judge between, or doubt. ἀνακρίνω (anakrinō, G350) — to examine, investigate, or question closely.
