ἀληθινός

true, real, genuine

Definition

The adjective ἀληθινός describes something that is true, real, or genuine, often in contrast to what is false, counterfeit, or merely symbolic. It denotes authenticity and reliability. In John's writings, it frequently characterizes God and divine realities: God is the 'true God' (John 17:3), Jesus is the 'true light' (John 1:9) and the 'true vine' (John 15:1), and believers worship in 'spirit and truth' (John 4:23). In other contexts, it describes genuine faithfulness (Luke 16:11) or the real, heavenly substance as opposed to earthly copies (Hebrews 8:2, 9:24).

Biblical Usage

This word appears 25 times, with a strong concentration in the Johannine literature (Gospel of John, 1 John, Revelation) and Hebrews. In John, it is used theologically to define the nature of God, Christ, and authentic worship. In Luke 16:11, it describes 'true riches' as opposed to worldly wealth. In Hebrews, it contrasts heavenly realities with earthly shadows (Hebrews 8:2; 9:24). Revelation uses it for God's 'true and just' judgments (Revelation 15:3; 16:7; 19:2).

Etymology

Derived from ἀλήθεια (alētheia, G225, 'truth'), with the adjectival suffix -ινός. Its root meaning relates to something that is not hidden or forgotten (from λανθάνω, 'to escape notice'). Thus, ἀληθινός fundamentally describes what is unconcealed, authentic, and in full accordance with reality, moving from a general sense of 'real' to a theologically loaded sense of 'divinely genuine.'

Semantic Range

This word is crucial for understanding biblical revelation. It distinguishes the one true God from idols (1 Thessalonians 1:9; 1 John 5:20) and Christ as the ultimate reality from all precursors and symbols (John 1:9; 15:1). It anchors Christian worship in the truth of God's character (John 4:23-24) and assures believers that their faith is based on a genuine, reliable object—God Himself. Understanding this term enriches reading by highlighting the Bible's contrast between the transient world and eternal, divine reality.

In a Greco-Roman world with many competing gods and philosophical ideas, the claim that something was 'ἀληθινός' was a strong assertion of exclusive authenticity and reliability. It countered polytheism and philosophical abstractions by pointing to a God who is fundamentally real and personally knowable. This stood in contrast to gods who were seen as distant, mythical, or merely symbolic representations.

ἀληθής (alēthēs, G227) — emphasizes truthfulness in statement or character (e.g., 'true witness'). ἀληθινός emphasizes genuine essence or reality.
