σκληροκαρδία

hardness of heart

Definition

Σκληροκαρδία (sklērokardia) refers to a spiritual and moral condition of 'hardness of heart.' It describes a willful stubbornness, an insensitivity or resistance to God's will, truth, or grace. In its biblical usage, it signifies a heart that has become calloused and unresponsive, leading to disobedience and a lack of faith. In Matthew 19:8 and Mark 10:5, Jesus attributes Moses' concession on divorce to humanity's 'hardness of heart,' indicating a deep-seated moral failure. In Mark 16:14, Jesus rebukes the disciples for their unbelief and hardness of heart after his resurrection, showing it as a barrier to accepting divine revelation.

Biblical Usage

This word is used three times in the Synoptic Gospels. It appears in two primary contexts: first, in discussions of the Mosaic Law (Matthew 19:8, Mark 10:5), where it explains the origin of certain legal concessions due to human sinfulness. Second, it describes the disciples' initial failure to believe the resurrection reports (Mark 16:14). The usage consistently portrays σκληροκαρδία as a fundamental human problem that obstructs right relationship with God and acceptance of His work.

Etymology

A compound noun from σκληρός (sklēros, G4642), meaning 'hard, harsh, or dry,' and καρδία (kardia, G2588), meaning 'heart.' Literally, it means 'hard-heartedness.' The 'heart' (kardia) in biblical Greek represents the center of intellect, emotion, and will. Thus, the term denotes a comprehensive inner rigidity affecting one's understanding, feelings, and decisions.

Semantic Range

This word is theologically significant as it diagnoses the core human condition of sin: a willful resistance to God. It explains the need for divine grace and the new covenant promise of a heart of flesh replacing a heart of stone (Ezekiel 36:26). Understanding this Greek term enriches reading by highlighting that biblical 'hardness' is not mere intellectual doubt but a deep-seated orientation of the whole person away from God, which only God's Spirit can overcome.

In the ancient Mediterranean world, the 'heart' was seen as the seat of thought and moral character, not just emotion. 'Hardness' could evoke imagery of something dried up, unyielding, or calloused, like parched earth or a stubborn stone. This contrasts with some modern views that might see 'hardness of heart' primarily as emotional coldness; the biblical concept is more holistic, involving the mind and will.

πώρωσις (pōrōsis, G4457) — a 'hardening' or 'blindness,' often used for a judicial hardening from God (e.g., Mark 3:5, Romans 11:7). ἀπιστία (apistia, G570) — 'unbelief' or 'faithlessness,' a key result of a hardened heart (Mark 16:14).
