Word Study

In depth

A plain-language study of pseudḗs — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Greek word pseudḗs, represented by G5571, refers to that which is untrue, deceitful, or wicked. It appears 3 times across 3 unique verses in the Bible and is translated as false or liar. The term carries the core meaning of being erroneous and intentionally misleading.

Biblical Occurrences & Contextual Analysis

In its biblical usage, G5571 is applied in critical contexts of truth and deception. It is used to label "false witnesses" who were set up to speak blasphemous words against the law and holy place Acts 6:13. The word also identifies those who falsely claim religious authority, as the church in Ephesus is commended for testing those who claimed to be apostles and finding them to be liars Revelation 2:2. Ultimately, the term describes a category of people who face final judgment, with "all liars" having their part in the lake of fire Revelation 21:8.

Related Words & Concepts

Several related words provide a broader context for the concept of falsehood:

  • G3144 mártys (witness): Defined as "a witness (literally (judicially) or figuratively (genitive case)); by analogy, a 'martyr'". This term is directly qualified by G5571 to describe the "false witnesses" brought against Stephen Acts 6:13.
  • G652 apóstolos (apostle): Meaning "a delegate; specially, an ambassador of the Gospel; officially a commissioner of Christ ('apostle')". This is the title falsely claimed by those who are ultimately found to be liars Revelation 2:2.
  • G571 ápistos (unbelieving): This term for one who is "disbelieving, i.e. without Christian faith" or "untrustworthy" appears alongside "liars" in the list of those who face the second death Revelation 21:8.

Theological Significance

The theological weight of G5571 is demonstrated in its consequences.

  • Corruption of Justice: The word is used to describe "false witnesses" G5571 G3144 whose testimony consists of "blasphemous words" G989, showing how deceit is used to attack divine law and holy institutions Acts 6:13.
  • False Religious Authority: It is used to expose individuals who claim to be apostles G652 but are not, identifying them as liars G5571. This highlights the necessity of testing claims of spiritual leadership Revelation 2:2.
  • Ultimate Condemnation: Being a liar is listed as a character trait that results in eternal judgment. In Revelation, "all liars" are grouped with the fearful G1169, unbelieving G571, murderers G5406, and idolaters G1496, sealing their fate in the "lake which burneth with fire" Revelation 21:8.

Summary

In summary, G5571 is a significant term defining more than just simple untruth. It points to a deliberate and wicked deceit that corrupts legal testimony, undermines true religious authority, and is counted among the most serious sins. The uses of pseudḗs in scripture demonstrate that falsehood has grave consequences, positioning it as a fundamental opposition to the truth that leads to judgment.
