The dominant theological / christological weight rests on (1).

Theological force, the name as doctrine

The personal name Iēsous / Yeshuaʿ is itself a theological statement. Matthew 1.21 makes the etymology explicit: "you shall call His name Jesus, for He will save His people from their sins" (καλέσεις τὸ ὄνομα αὐτοῦ Ἰησοῦν, αὐτὸς γὰρ σώσει τὸν λαὸν αὐτοῦ ἀπὸ τῶν ἁμαρτιῶν αὐτῶν). The angel's for (γάρ) glosses the Hebrew etymology directly: the name is the function, "YHWH saves" embodied in the bearer.

The Christological force activates in three directions:

The name itself asserts divine identity. The name Yeshuaʿ is "YHWH saves", and in the Gospels, He is the One who saves. The implication: the bearer of the name is the YHWH-of-the-name in person. Justin Martyr (Dialogue with Trypho 75) and Cyril of Jerusalem (Catech. 10.11) develop this argument early.
The name carries OT exclusivity-of-salvation. Isaiah 43:11, "I, even I, am the LORD; and there is no Savior (moshiaʿ) besides Me." Joel 2:32, "whoever calls on the name of the LORD will be saved." Paul's application of Joel 2:32 to Jesus in Romans 10:13 is the canonical-hinge text: the YHWH-text becomes a Jesus-text. Acts 4:12, "there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved."
The name is the typological hinge to the OT Joshua. Yehoshuaʿ led Israel into the land of promise, but Hebrews 4:8 explicitly notes that "if Iēsous (Joshua) had given them rest, He would not have spoken of another day after that," opening the typological space the true Joshua / Jesus fills: bringing the people into the eschatological inheritance.

The "Jesus Christ" dyad. Iēsous Christos combines the personal name (Yeshuaʿ, YHWH saves) with the messianic title (G5547 - christos, anointed). The dyad is canonical and theologically saturated: the One named YHWH-saves is the Anointed One. Paul's standard greeting charis humin kai eirēnē apo theou patros hēmōn kai kyriou Iēsou Christou ("grace and peace from God our Father and the Lord Jesus Christ") is a high-Christological assertion: the theos-pater and kyrios Iēsous Christos together constitute the divine source of grace and peace.

Patristic / scholarly note

The Christological argument from the name is among the oldest in the Christian tradition. Justin Martyr (Dialogue with Trypho 75), Joshua's name = Jesus's name; the typology is exact. Origen (Homilies on Joshua), develops the Joshua-Jesus typology in 26 sermons. Cyril of Jerusalem (Catechetical Lectures 10.11), reads the etymology as transparent doctrinal claim: the One who saves is the YHWH-Savior. Athanasius (De Incarnatione), the name-bearer as God-in-flesh.

In Reformation-evangelical scholarship (B.B. Warfield; Murray Harris, Jesus as God: The New Testament Use of Theos in Reference to Jesus, 1992; Sinclair Ferguson, In Christ Alone, 2007; David B. Capes, The Divine Christ: Paul, the Lord Jesus, and the Scriptures of Israel, 2018), the etymology functions as a load-bearing piece of high-Christology defense: the name itself transferred YHWH-salvation to the bearer.

The name is also significant for Messianic Jewish apologetics: the post-exilic shift from Yehoshuaʿ to Yeshuaʿ prepares the Greek Iēsous; the recovery of Yeshuaʿ (the Hebrew form) in modern Messianic Judaism connects contemporary Jewish-Christian dialogue to the Christ's actual Aramaic name.

The Latin tradition (Vulgate Iesus) and English tradition (Jesus, with the J representing the original consonantal I/Y) preserve the chain: Yehoshuaʿ → Yeshuaʿ → Iēsous → Iesus → Jesus.
