pseustes identifies a person marked by a false assertion, including claims contradicted by conduct or testimony.

The dominant usage identifies someone whose stated claim is exposed as false or inconsistent with conduct, testimony, or acknowledged knowledge. Other occurrences apply the designation to one who speaks a lie and use plural forms as labels in a vice list and a quoted group characterization.

1. A person whose claim is contradicted · dominant

   In 1 John 2:4, the nominative singular occurs of someone who says he has known him but does not keep his commandments; the APB renders the conclusion "is a liar." In 1 John 2:22, it identifies the one denying that Jesus is the Christ, while 1 John 4:20 applies it to the person claiming love for God while hating his brother. In John 8:55, the same form is used hypothetically of saying, "I do not know him," despite the speaker's stated knowledge.

   In John 8:44, the nominative singular describes the devilish one in the clause, "When he speaks the lie, he speaks from his own things," followed by the APB rendering "he is a liar and the father of it." The verse directly connects the designation with speaking the lie.

   In 1 Timothy 1:10, the dative plural appears among people listed as opposed to sound teaching; the APB includes "for liars" in that list. In Titus 1:12, the nominative plural occurs in a quoted statement characterizing Cretans as "always liars," alongside other negative descriptions.

In the Anselm Project Bible: Across the supplied verses, the APB regularly renders the term with "liar" or "liars," including descriptions of false claims, speaking the lie, a vice list, and a quoted characterization. Because the APB is a whole-verse translation, these renderings are read in their clause contexts.
