Θεοῦ (Theou) in Romans 3:7: Noun Genitive Singular Masculine

Noun: the form names a person or being, here referring to God, and the noun itself does not change the basic lemma meaning.

Genitive: the form usually marks a dependent relation, so here it links God to the nearby noun for truth in a modifying phrase.

Singular: the form is grammatically singular in this occurrence, presenting one referent in the clause.

Masculine: the noun is tagged masculine in this form, which is a grammatical class and not by itself a theological or biological claim.

τοῦ Θεοῦ

The genitive is governed by the article and noun phrase for truth, creating a relationship of source, possession, or characterization that must be read from context.

It functions as a dependent modifier in the phrase, identifying the truth as belonging to or coming from God.

It does not by itself make God the direct subject of the verb, and it does not force one single nuance beyond what the sentence supports.

High: The genitive noun anchors the truth phrase in God as Paul contrasts divine truth, human falsehood, and divine glory.

Genitive singular noun modifying truth. marks the truth as belonging to, coming from, or being characterized by God. Attached to the truth phrase in Romans 3:7. Governed by the noun phrase that contrasts God-related truth with the speaker's lie. The form gives the truth phrase its divine relation while the sentence keeps the contrast with falsehood in view.

Whose truth is named? The genitive ties the truth to God, so the verse speaks of truth in relation to God rather than truth in abstraction.

Direct: The genitive directly supports wording such as "the truth of God" or "God's truth."

The genitive relation may be heard as possession, source, or characterization, but the contrast with falsehood and glory guides the phrase. The form does not decide every nuance of the verse apart from the rhetorical argument around it.

Genitive case fully defines divine truth: The form marks relation to God; the clause and argument explain the theological force. grammar replaces the rhetorical context: The genitive should be read inside the contrast between truth, lie, and glory.

The witness reads Θεοῦ in Romans 3:7, within the phrase ἡ ἀλήθεια τοῦ Θεοῦ, and the surrounding clause contrasts truth, lie, and glory.

The lemma θεός here names God, and the lexicon entry allows the term to refer to the one true God in contexts like this one.

The genitive links God to truth, so the phrase naturally reads as God's truth, truth from God, or truth characterized by God, with context favoring a close possessive or source sense.

In this argument, the point is not about a bare dictionary sense but about how God's truth stands in relation to human falsehood and divine glory.

This fits the broader biblical habit of speaking of truth as belonging to God and of God's character being displayed in faithful action.

For readers and translators, the form supports rendering the phrase as 'the truth of God' while explaining that the genitive expresses relationship, not a full theology by grammar alone.

Do not infer from genitive case alone a precise doctrinal formula, a change of lemma, or a claim that grammar settles every nuance of ownership, source, or quality.
