What The Form Does In This Verse

Attached To

πλήρης χάριτος καὶ ἀληθείας

Governed By

The genitive likely depends on the adjective πλήρης and helps complete the description of what the Word is full of.

Role In The Phrase

It functions as part of a genitive phrase that characterizes the Word's fullness, together with grace.

What It Is Not Doing

It does not by itself make truth a separate clause, a new subject, or a change in the lexeme's meaning.

How Much The Form Matters Here

Interpretive Weight

High: The genitive noun joins grace in describing the incarnate Word as full of truth.

Syntax Profile

Genitive singular noun completing the fullness description. names truth as part of the fullness attributed to the Word. Attached to the full of grace and truth phrase in John 1:14. Governed by the adjective full in the description of the Word. The form contributes to the Word's revealed character, while the clause as a whole carries the incarnation claim.

Reader Question

What fills or characterizes the Word in this phrase? Truth, joined with grace, characterizes the fullness described in the incarnate Word.

Translation Effect

Direct: The genitive relation directly supports wording such as "full of grace and truth."

Where Caution Is Needed

The genitive is controlled by the fullness description and should not be isolated from grace or the incarnation clause. The feminine grammatical form belongs to the noun class and does not personalize truth by itself.

Fallacies To Avoid

Genitive alone defines truth as a technical category: The form names truth in the fullness phrase; John's context supplies the theological content. truth is detached from the Word made flesh: The phrase belongs to John 1:14's portrait of the incarnate Word and should be interpreted there.

How The Interpretation Is Derived

Textual Witness

The witness reads ἀληθείας in John 1:14 within the phrase πλήρης χάριτος καὶ ἀληθείας.

Lexical Identity

The lemma is ἀλήθεια, which in this context carries the sense of truth as reality, reliability, or veracity.

Grammar In Context

Passage Meaning

John 1:14 portrays the incarnate Word as embodying grace and truth together, not as a mere speaker about them.

Canonical Fit

This fits the Gospel's larger emphasis on revelation, where truth is bound to the revealing work of God in the Son.

Communication Use

In teaching, the form supports saying that the verse describes the Word as marked by truth, while the exact genitive relation should remain modestly stated.

Do Not Derive

Do not infer that the case alone proves a single technical relation, or that grammatical gender adds doctrinal meaning.
