Jesus and Yahweh
The question of whether Jesus is Yahweh turns on the identity of the God of Israel and on how the New Testament relates Jesus to that God. In its strongest form, the distinction claim holds that Yahweh is a single divine person — the Father — and that Jesus is a distinct figure, the Son, who is neither identical with the Father nor identical with Yahweh. The claim is defended in two main forms: as a historical judgment about what the biblical texts say, and as the defining doctrinal conviction of biblical unitarianism and related non-Trinitarian traditions. Bart Ehrman states the historical version bluntly: "The Bible, of course, does not have the Trinity, but when Christian theology formulated the doctrine of the trinity, the Father was Yahweh, and Christ was his son."[^c1] The analytic philosopher Dale Tuggy argues the theological version as a cumulative case: "there are some twenty obvious facts about the New Testament which make some variety of non-Trinitarian theology more likely."[^c2] The distinction is not a denial that the New Testament calls Jesus "God"; its defenders argue that the title can attach to an authorized agent: "Jesus can be called Yahweh in his role as Yahweh's agent, without being identified with Yahweh himself."[^c9]
The debate is driven by two sets of texts. One set distinguishes Jesus from God: he prays to the Father, calls the Father "the only true God," says that the Father is greater, is sent, obeys, suffers, dies, and is exalted. The other set identifies Jesus with God: New Testament authors apply Yahweh texts to him, credit him with creation, place him on the divine throne, and worship him alongside the Father. The central test cases are the Shema of Deuteronomy 6:4, its restructuring in 1 Corinthians 8:6, the prologue of John, the Christ hymn of Philippians 2, the catena of Hebrews 1, and the throne scene of Revelation 4-5. Trinitarians read the identification pattern as proof that Jesus belongs to the identity of Yahweh: "believers were not calling Jesus a second god or a demi-god but ascribing to him the very identity of Yahweh."[^c3] A recent statement of the case frames it as a historical pattern rather than a single proof: "The claim is not that any one verse settles the doctrine of the Trinity; it is that a consistent, deliberate pattern runs across distinct kinds of early material, and that the pattern is very hard to explain if Jesus was, for these writers, anything less than the LORD."[^c12] Against this, Richard Bauckham's thesis that "earliest Christology was already the highest Christology" is itself contested by critics who argue that the phrase "divine identity" is either self-inconsistent or too thin to bear the doctrinal weight placed on it.[^c5][^c7] The pre-existence language that the identification texts presuppose is increasingly read against Jewish personified Wisdom, whose attributes are transferred to Christ in Hebrews, Colossians, and the prologue of John; whether that background entails a distinct pre-existent subject or only a personification of God's activity is itself disputed.[^c11]
Three traditions frame the dispute. Trinitarianism holds that the one God exists in three distinct persons, so that the Son is included in the divine identity without being the Father. Biblical unitarianism holds that the one God is the Father alone and that Jesus is the Son whom God sent and exalted. Jehovah's Witnesses and Oneness Pentecostals represent further positions, the first subordinationist and the second modalist. Jewish interpretation supplies the sharpest external challenge, insisting that the Shema excludes any plurality within God, while the study of Second Temple intermediaries has complicated the assumption that Jewish monotheism was always strictly unipersonal. The rabbinic polemic against "two powers in heaven" is now read by scholars as evidence that "the rabbinic 'two powers' polemics were, especially in the earlier period not only directed at Christianity but at a plurality of beliefs that circulated in first century Judaism."[^c10]
The historical development of the question runs from the worship practices of the earliest Christian communities through the councils of Nicaea and Chalcedon. Larry Hurtado describes the worship of Jesus as "a novel and historically significant 'mutation'" within Jewish cultic exclusivity, while Philo's Logos illustrates a Second Temple intermediary that is neither uncreated God nor ordinary creature[^c8]. The councils defined the Son as consubstantial with the Father and one person in two natures, although a reference encyclopedia notes that "Even in the New Testament the doctrine of the Trinity is not enunciated, though it is deduced from a collocation of passages."[^c6] Modern scholarship has reopened the question through the concept of divine identity, the study of Second Temple intermediaries, and analytic debates about identity, predication, and the coherence of a unipersonal God. Recent Trinitarian proposals also press the one-self/three-self question in new directions, including "Aspectival Monotheism," which describes "one God, one divine self, and real inseparable aspects within His one undivided being."[^c13]
