ἄπιστος
ápistos
unbelieving
Not trusting, not believing; lacking in faith or trust. The term is used to describe someone who does not believe, who is skeptical, or who is untrustworthy. Depending on context, it denotes either unbelief (as in religious or general conviction), lack of trustworthiness (in character or promise), or something not credible. In relation to communities defined by faith, particularly in the New Testament, it often designates those outside such a community: e.g., a person who does not share the belief of the group, or does not hold faith in the proclaimed message. In a broader sense, it can also refer to a lack of reliability or incredibility (something not to be believed).

| Morphological Notes | Adjective, nominative masculine singular; functioning substantivally to describe a person characterized by lack of faith or trust. |
| Rendering Rationale | The alpha privative negates πιστός (trusting, faithful), yielding "not trusting" or "lacking faith." As nominative masculine singular, it denotes a person characterized by unbelief, hence "unbelieving one." |
