ψευδής

false, deceitful, lying

Definition

The adjective ψευδής fundamentally describes something or someone that is false, deceitful, or lying. It characterizes a person who is untruthful, as seen in the false witnesses (ψευδείς μάρτυρες) who accused Stephen in Acts 6:13. It also describes the quality of falsehood itself, such as the 'false apostles' (ψευδαπόστολοι) mentioned in Revelation 2:2. In its most severe theological application, it labels 'all liars' (πᾶσιν τοῖς ψευδέσιν) as those whose ultimate fate is condemnation in Revelation 21:8.

Biblical Usage

This word is used three times in the New Testament, appearing in Acts and Revelation. In Acts 6:13, it describes human agents of deception—false witnesses. In Revelation, it is used twice in contexts of spiritual discernment and final judgment. Revelation 2:2 uses it to commend the church for testing and rejecting those who claim apostolic authority falsely. Revelation 21:8 categorically condemns all who practice falsehood, listing them among those excluded from God's new creation.

Etymology

Derived from the Greek verb ψεύδομαι (pseudomai, G5574), meaning 'to lie' or 'to deceive.' The adjective ψευδής is the root for many compound words in the New Testament, such as ψευδάδελφος (false brother) and ψευδοπροφήτης (false prophet). Its core meaning of intentional falsehood or misrepresentation is consistent from its root.

Semantic Range

This word is theologically significant as it directly contrasts with the nature of God, who is truth (John 14:6). It identifies a fundamental characteristic of evil, deception, which originates with Satan, 'the father of lies' (John 8:44). Understanding ψευδής enriches reading by highlighting the serious biblical condemnation of falsehood, not merely as a social fault but as a spiritual poison that corrupts testimony (Acts 6:13), misleads the church (Rev. 2:2), and separates people from God's eternal kingdom (Rev. 21:8).

In the ancient Greco-Roman world, bearing false witness was a serious social and legal offense, as trust (pistis) was a cornerstone of relationships and commerce. For Jews, the Ninth Commandment explicitly forbade false testimony. The biblical use of ψευδής, therefore, carries this weight of violating sacred social, legal, and divine standards of truth-telling.

ψεύστης (pseustēs, G5583) — A 'liar,' the personal noun form focusing on the person characterized by falsehood. ψεῦδος (pseudos, G5579) — The noun 'a lie' or 'falsehood,' focusing on the thing itself rather than the quality or person.
