ἀλήθεια

From the study of John 1:17

Range of meaning

In classical Greek: what is real or genuine, what is not hidden, as opposed to falsehood or appearance. In Jewish Greek it often translates Hebrew 'emet, meaning firmness, reliability and faithfulness (from the same root as 'amen'). John uses it for the reality of God that Jesus reveals and embodies ('I am the way, the truth', 14:6).

Against the English

Modern 'truth' usually means a correct statement or accurate information. In this pairing it is closer to 'faithfulness' or 'trustworthy reality': God being what he says he is and keeping his word. The NLT brings this out ('faithfulness'); most versions keep 'truth'.

How it drifted

Modern ideas of truth as matching the facts, and church uses of 'truth' for correct doctrine, narrow a word that in Hebrew-shaped Greek also carried relational reliability.

Used elsewhere in the period

In LXX Exod 34:6 God is alēthinos ('true/faithful'). Eleos kai alētheia ('mercy and truth') is a standard Septuagint rendering of ḥesed we'emet (e.g., Ps 25:10, 89:14; Prov 3:3). The Dead Sea Scrolls often speak of God's 'emet and his ḥesed together.

From the study of Ephesians 6:14

Range of meaning

In Greek generally: what is real and not concealed, truth as opposed to falsehood. In the Greek Old Testament it often translates Hebrew ʾemet and ʾemunah, which mean firmness, reliability, faithfulness. So in Jewish Greek, 'truth' leans toward what can be relied on and toward faithful dealing, not only toward accurate statements (BDAG s.v. ἀλήθεια 1–3).

Against the English

English 'truth' tends to mean correct information or right doctrine. All English versions say 'truth', which is fine, but readers may narrow it to 'knowing the right beliefs' and miss the sense of integrity and faithfulness.

How it drifted

Modern English, shaped by philosophy and science, treats truth mainly as accurate propositions. The biblical background adds trustworthiness and faithful conduct.

Used elsewhere in the period

Isa 11:5: Hebrew 'faithfulness (ʾemunah) the belt of his waist'; LXX 'wrapped with truth (ἀληθείᾳ)'. Isa 59:14–15 laments that 'truth has stumbled in the public square' just before God arms himself (59:17). Within Ephesians: 'the word of truth, the gospel' (1:13); 'truth is in Jesus' (4:21); 'speaking the truth in love' (4:15); 'put off falsehood, speak truth' (4:25); 'the fruit of light is in all goodness, righteousness and truth' (5:9). The Dead Sea Scrolls likewise set a 'spirit of truth' against a 'spirit of deceit' (1QS 3–4).

From the study of John 14:6

Range of meaning

Ordinary Greek: what is not hidden or false, what is actually the case, reality, sincerity. In the Greek Old Testament it mostly translates Hebrew 'emet, a word built on the idea of firmness: reliability, faithfulness, trustworthiness, as in God's "steadfast love and faithfulness" (ḥesed we-'emet). BDAG gives (1) the quality of being dependable, sincerity, faithfulness, (2) what corresponds to fact, and (3) reality as opposed to appearance. John's use draws on all three.

Against the English

"Truth" is the right word, but modern readers usually hear correct information, an accurate statement, or a philosophical thesis about "absolute truth." John's alētheia is fuller: the real nature of God made openly known, and found faithful. In John you can "do the truth" (3:21), be "of the truth" (18:37), and be set free by it (8:32).

How it drifted

Since the early modern period, "truth" in English has narrowed toward "a statement that matches the facts." Modern debates about relativism have made the verse a slogan for "objective truth," and the relational, Hebrew-shaped sense recedes.

Used elsewhere in the period

LXX Ps 85(86):15 and Exod 34:6 "abounding in mercy and truth ('emet)"; Ps 118(119):142 "your law is truth"; 119:151 "all your commandments are truth." At Qumran the faithful are "sons of truth" and are told to "do truth" (1QS 1.5; 4.5–6). In John: the Word is "full of grace and truth" (1:14); "the law was given through Moses; grace and truth came through Jesus Christ" (1:17); "your word is truth" (17:17); Pilate's "What is truth?" (18:38).
