U- Unveiling the Word

The word ψεῦδος carries profound theological weight in New Testament literature, representing not merely casual untruths but deliberate falsification and moral opposition to truth. Its primary meaning of “falsehood” or “lie” extends into broader concepts of deception, delusion, and purposeful misrepresentation. In early church usage, it became particularly significant in discussions about false teaching and spiritual warfare, often contrasted with ἀλήθεια (truth). The early church fathers frequently used this term when addressing heretical teachings. Today, it remains relevant in discussions of truth, integrity, and spiritual discernment, particularly in an era of “fake news” and digital deception.
