ἀληθής

unconcealed, true

Definition

The adjective ἀληθής fundamentally means 'true' or 'truthful,' describing something that corresponds to reality and is not hidden or false. In the New Testament, it describes God as being faithful and reliable (John 3:33, 7:18), and Jesus as a true witness whose testimony is trustworthy (John 5:31-32, 8:13). It also characterizes people's words or character as being honest and sincere, as seen when the Pharisees, with irony, call Jesus a teacher who is 'true' (Matthew 22:16, Mark 12:14). In John 4:18, it describes a statement as being factually 'true.'

Biblical Usage

ἀληθής is used 25 times, predominantly in the Gospel of John (10 times) and the Johannine epistles, where it is central to discussions of truth and testimony. It often appears in legal or testimonial contexts concerning the reliability of witnesses, especially regarding Jesus and God (John 5:31-32, 8:13). It is also used in narrative descriptions of honest character or factual statements (John 4:18, Matthew 22:16). Its usage emphasizes objective reality and trustworthy reliability.

Etymology

Derived from the alpha-privative ἀ- ('not') and the root *lath- (related to λανθάνω, 'to escape notice,' and λήθη, 'forgetfulness' or 'oblivion'). Thus, its core meaning is 'not hidden,' 'unconcealed,' or 'not forgotten.' This etymology highlights truth as that which is brought to light and corresponds to what is real and enduring, not merely what is subjectively believed.

Semantic Range

This word is theologically significant as it describes the very nature of God and Christ. God is 'true' (John 3:33), meaning He is faithful to His promises and character. Jesus is the 'true' witness, revealing the Father. In a world of falsehood, ἀληθής points to the ultimate reality found in God, forming a foundation for doctrines of revelation, Christology, and the trustworthiness of Scripture. Understanding this Greek term enriches reading by emphasizing that biblical truth is about reliable, unveiled reality, not just abstract ideas.

In the Greco-Roman world, philosophical discussions about truth (alētheia) were common, often focusing on correspondence to reality. In the Jewish context, truth was closely tied to God's faithfulness and covenant reliability. The New Testament use of ἀληθής bridges these ideas, presenting truth not just as factual accuracy but as the faithful, reliable character of God revealed in Christ, contrasting with human deceit and instability.

ἀληθινός (alēthinos, G228) — emphasizes genuineness, authenticity, or the ultimate reality as opposed to a copy. ἀλήθεια (alētheia, G225) — the noun 'truth,' the abstract concept or content of what is true.
