Ἰησοῦ

The genitive form most naturally participates in the chain of names in Matthew 1:1 and links closely with Jesus and the sonship language that follows.

It helps identify Jesus as Messiah within the opening genealogy, so the phrase reads as a labeled relationship rather than a standalone statement.

It does not by itself prove a full sentence meaning, and it does not force a meaning beyond the verse's genealogical and titular context.

Genitive title in an opening genealogy heading. identifies Jesus by messianic title within the genealogy's opening frame. Attached to the Jesus Christ name-title phrase.

Who is Matthew identifying at the start of the genealogy? He identifies Jesus as Christ, the Messiah, in connection with David and Abraham.

Direct: The form directly supports the title-bearing rendering Jesus Christ in the opening heading.

The phrase should not be reduced to a modern first-and-last-name pattern; Christ is a title in this context. The genitive chain contributes to the heading, but the whole verse supplies the covenant connections.

Genitive chain proves every covenant implication by itself: The grammar supports the heading; Matthew's whole opening line and genealogy carry the covenant argument.

The witness reads Χριστοῦ in Matthew 1:1, within the phrase Βίβλος γενέσεως Ἰησοῦ Χριστοῦ, υἱοῦ Δαβίδ, υἱοῦ Ἀβραάμ.

The lemma Χριστός commonly names the Anointed One, the Messiah, and in this context it is a recognized title for Jesus.

The genitive form fits the chain of relationships in the verse and supports reading the phrase as Jesus' messianic identification within the genealogy.

Matthew opens by presenting Jesus as the Messiah in line with David and Abraham, so the form contributes to a royal and covenantal introduction.

This aligns with the book's broader emphasis on Jesus as the promised king and Messiah within the covenant story.

For readers and teachers, the form helps explain why the opening line names Jesus not only by name but also by messianic identity.

Do not derive a different lemma, a hidden sentence, or a gender doctrine from the case or masculine form alone.
