πίστις

faith, belief, trust

Definition

Pistis fundamentally means 'faith' or 'trust,' denoting a personal conviction and reliance, especially upon God and Christ. In the New Testament, it often refers to the act of believing for salvation, as seen in Ephesians 2:8 ('For by grace you have been saved through faith'). It also describes the content of what is believed, the 'faith' as a body of doctrine (Jude 1:3). Furthermore, pistis can mean 'faithfulness' or 'fidelity,' describing reliable character, as in Galatians 5:22 where it is listed as a fruit of the Spirit.

Biblical Usage

Pistis is used extensively across the New Testament, especially in the Pauline epistles and the Gospels. In the Gospels, it frequently describes the active, trusting faith of individuals seeking healing from Jesus (e.g., Matthew 9:22). Paul uses it heavily to explain the mechanism of justification and the believer's relationship with God (e.g., Romans 3:28). The word also appears in lists of virtues (2 Peter 1:5) and can describe steadfastness or reliability (Romans 3:3).

Etymology

Derived from the Greek verb πείθω (peithō, G3982), meaning 'to persuade' or 'to trust.' The noun pistis carries the core idea of being persuaded, leading to trust, confidence, and faithfulness. This root connection highlights that biblical faith is not blind but involves a convinced mind and a committed trust.

Semantic Range

Pistis is a cornerstone of New Testament theology. It is central to the doctrine of justification by faith alone (sola fide), defining how humans are made right with God (Romans 5:1). It describes the essential posture of the Christian life—trusting in Christ from start to finish (Hebrews 12:2). Understanding its range from personal trust to doctrinal content enriches reading by showing that faith is both relational and propositional.

In the Greco-Roman world, pistis could refer to general trustworthiness or good faith in social and commercial agreements. The New Testament authors infused this common term with profound theological meaning, anchoring it specifically in trust in the God of Israel as revealed in Jesus Christ. This shifted the focus from general reliability to a saving, covenantal relationship.

ἐλπίς (elpis, G1680) — hope; a forward-looking trust and expectation. πληροφορία (plērophoria, G4136) — full assurance or complete certainty, often a result of strong faith. πιστεύω (pisteuō, G4100) — the verb 'to believe' or 'to have faith,' denoting the action.
