καθαρότης

cleanness, purity

Definition

Katharotēs refers to the state or quality of being clean, pure, or free from contamination. In its primary sense, it denotes physical cleanness or purification, as seen in its sole New Testament use regarding the ceremonial purification of the flesh (Hebrews 9:13). More broadly, the concept extends to moral and ritual purity, implying freedom from defilement, guilt, or sin. While the New Testament uses the noun only once, the related adjective (katharos, G2513) and verb (katharizō, G2511) are frequently applied to spiritual cleansing through Christ's sacrifice.

Biblical Usage

This word is used only once in the New Testament, in Hebrews 9:13. Here, it describes the outward, ceremonial purity achieved through the Old Testament sacrificial system—specifically, the sprinkling of the ashes of a heifer to purify those who were ritually defiled. This singular usage serves as a contrast to the superior, inward cleansing brought by the blood of Christ, which is the central argument of the passage. The word appears in a context comparing the old and new covenants.

Etymology

Katharotēs is a noun derived from the adjective katharos (G2513), meaning 'clean, pure, or free from admixture.' The root conveys the idea of being unsoiled, unmixed, or clear. The suffix -tēs forms an abstract noun indicating a state or quality, thus 'the state of purity.' Cognates include the verb katharizō (G2511, 'to cleanse, purify') and the noun katharismos (G2512, 'a cleansing, purification').

Semantic Range

This word is theologically significant as it highlights a key contrast in the book of Hebrews. The 'cleanness' (katharotēs) provided by the old covenant was external, ceremonial, and temporary, pertaining only to the flesh. This sets the stage for the author's argument for the superior, internal, and permanent purification of the conscience accomplished by the blood of Christ (Hebrews 9:14). Understanding this Greek term enriches the reading of Hebrews by clarifying the nature of the old purification as a mere shadow pointing to the true cleansing found in Jesus.

In the ancient Greco-Roman and Jewish world, purity was a major cultural and religious concern. Physical and ritual purity were often seen as prerequisites for approaching the divine or participating in community life. The Jewish system had elaborate laws (e.g., in Leviticus) for purification from various defilements. The concept in Hebrews 9:13 would have been immediately understood by a 1st-century audience as referring to this established system of ritual washings and sacrifices, which provided a tangible but limited cleansing.

katharismos (G2512) — focuses more on the act or process of cleansing/purification. hagnotēs (G54) — emphasizes moral purity, innocence, or chastity. eilikrineia (G1505) — denotes sincerity, purity of motive, or clarity.
