PREFACE
The titles “Son of Man” and “Son of God” do not emerge in a vacuum. They are not abstract labels dropped straight out of heaven, nor are they timeless doctrinal tags awaiting eventual systematization in later creeds. Rather, they are products of history: shaped, stretched, and reconfigured across centuries of worship, trauma, political reordering, and theological imagination.
In this respect, the development of these titles belongs to the same long arc as traced in our most recent past series covering the (Mesopotamian) Evolution of Worship and Religion. Here, ancient Near Eastern religion moved from city-based polytheisms and divine councils to the exaltation of high gods; from sacral kingship to more interiorized forms of piety; from cyclical myth to linear-apocalyptic expectation. Israel did not stand apart from these currents. It participated in them for their own purposes and reasons - at times resisting religious teachings, reworking, re-imagining, or intensifying them around the evolving figure of Yahweh and the community that bore his name (sic, "Y'Israel" - "He who struggles or contends with El (God)" re Jacob's wrestling with the divine, Gen 32.24-30).
"That night Jacob got up and took his two wives, his two servant wives and his eleven sons and crossed the ford of the Jabbok. After he had sent them over the stream, he himself went over and was alone. Then a man wrestled with him till daybreak, dislocating his hip, and renaming Jacob "Israel.""Your name will no longer be Jacob, but Israel, because you have struggled with God and with humans and have overcome.""So Jacob called the name of the place Peniel ("the face of God"), saying, 'It is because I saw God face to face, and my life has been preserved.'"Significance:
- Name Change - Jacob's name changes from Jacob (supplanter) to Israel (contends with God).
- New Identity - The encounter marks a pivotal moment, revealing a new identity and relationship with God.
- Blessing - Jacob's persistence in clinging to the figure for a blessing results in divine affirmation, even after being weakened.
I.
Within that evolving landscape came the development of the titles:
-
The idiom now translated “Son of Man” (ben ʾadam / bar enash) first functioned simply as a way of saying “a human being,” a mortal in distinction from the divine.
-
The designation “Son of God” (ben ʾelohim) which was applied to Israel as God’s “firstborn,” and to angelic beings in God's divine council, as well as to Israel's Davidic kings as Yahweh’s adopted royal sons.
These usages are formed deeply within the cultural landscapes of the Ancient Near Eastern and Israelite traditions... and not yet part of any distant Christian teachings. The Semitic apertures draw from a world in which the gods had children, kings were divinized or semi-divinized, and the language of sonship served to mark status, favor, and vocation rather than metaphysical essence.
Over time, however, these nomenclatures began to bear more weight. In the crucible of exile, imperial domination (Babylonian, Persian, and Roman), and the rise of apocalyptic hope, older idioms were taken up into new symbolic roles. The simple “son of man” of prophetic address became, in *Daniel and related literature, a heavenly, eschatological figure who receives authority from the Ancient of Days (referring to El/God's eternal, sovereign rule). The royal “son of God” language surrounding the Davidic king was intensified and transposed onto messianic expectation, even as concrete kingship vanished and hope shifted toward a future anointed one who would finally enact God’s justice.
*The 2nd-Century Book of Daniel is an Inter-Testamental Apocalypse written during the time of the Maccabees (167-164 BCE), referring to Israel's Babylonian several exiles (609, 605, 601, 598/97, 587, 582 BCE) and written or collected during the unwanted Greek rule of Antiochus Epiphanes IV.
It is precisely into this already-layered semantic field that Jesus and the early Jesus movement come forward. The Gospels, Apostle Paul, and other early Christian writings, do not invent these titles ex nihilo; they inherit and reconfigure them in light of the conviction that God has acted definitively in the life, death, and resurrection of Jesus of Nazareth. Jesus’ cryptic use of “Son of Man” and the early church’s bold application of “Son of God” to him are intelligible only when read against this deep background.
II.
At the same time, this developmental story sits firmly within the concerns raised in our earlier work on biblical inerrancy and the evolving character of Scripture. An inerrantist framework typically assumes that terms such as “Son of Man” and “Son of God” carry a single, stable meaning from Genesis to Revelation - often retrofitted to the church's systematic categories of later dogmatics (e.g., “Son of Man = Christ’s humanity,” “Son of God = Christ’s divinity”). But the historical record points in a different direction. What we see instead is a layered process of theological semantic growth and re-interpretation:
-
The same phrase of "Son of Man" can mean “mortal human” in one era and “heavenly eschatological figure” in another.
-
And the "Son of God" title can denote both royal adoption and covenantal status in one period and yet later become an ontological claim about eternal divine Sonship in a later period.
If Scripture is approached as a living, historically embedded tradition, rather than a flat repository of timeless propositions, this evolution is not a problem to be explained away. It is, instead, evidence of the Bible’s dynamic character: communities working with inherited language and meaning to articulate newly perceived realities of God and world - even as it did with Jesus' ministry, death, and resurrection. Within such a framework, development is not a betrayal of revelation but one of its primary modes.
This essay therefore proceeds on two convictions:
-
That the titles “Son of Man” and “Son of God” must be read within the concrete historical horizons that first gave them meaning - from Ancient Near Eastern royal ideology and Israel’s prophetic literature, through exilic and post-exilic reforms, apocalyptic imagination, the Jesus tradition, and the theological debates of the early church.
-
That the shifting meanings of these titles across the centuries are not mere accidents, but integral to the way divine revelation was being received and mediated: through evolving (existent) concepts, contested cultural interpretations, and ever-deepening attempts to describe the continually evolving epistemic realization of God's relationship with humanity in its periodic eras, eventuating towards the Christian confession of Jesus as God's sent/anointed Messiah.
In what follows, then, we will not treat “Son of Man” and “Son of God” as static doctrinal labels waiting to be decoded by later theology. We will instead follow these ascribed titles as historical trajectories - as relational phrases whose meanings are bent and expanded by each new historic experience, event, context, crisis, and act of theological imagination. Only against that backdrop can we understand how the early church eventually came to speak of Jesus Christ in Nicene terms of Risen God-Man, and why those later metaphysical formulations cannot simply be read back, uncritically, into Israel’s Scriptures or even into the earliest Christian texts themselves.
It is within this broader frame - the evolution of worship and religion from Mesopotamia onward, and the non-static, processual character of biblical language - that the following introduction and subsequent sections should be read.
Few christological titles have undergone such dramatic semantic transformation as “Son of Man” and “Son of God.” In popular Christian reception, these two expressions have come to serve as an early Christological binary: one supposedly expressing the humanity of Jesus, and the other the divinity of Jesus. Yet this binary is not only absent from the biblical world - it is, in fact, contradictory to the meanings these terms originally held in Ancient Israel and Second Temple Judaism.
To reconstruct the development of these titles, one must resist the temptation to impose later theological meanings onto earlier texts. Instead, each historic era confers it's own meaning upon these titles:
- Israel’s undivided monarchy,
- the Southern Kingdom's Exilic Period
- Post-Exilic Judaism
- Apocalyptic Judaism,
- the Jesus movement,
- the earliest post-Easter communities
- 2nd-3rd Century Christianity
- the Nicene period
- Post-Nicene Church eras
-
“Son of Man” begins primarily as an idiom for a human being, develops in apocalyptic Judaism into a heavenly eschatological figure, and is later adopted by the Jesus tradition in enigmatic, polyvalent ways.
-
“Son of God” begins in Israel as a title for the king, Israel itself, and angelic beings, develops as a relational and vocational title for the Messiah, and only later becomes a metaphysical designation expressing Jesus’ ontological divinity.
Thus, the story of these titles is not one of fixed definitions, but of historical evolution, interpretive layering, and theological recontextualization. The task of this essay is to illuminate these shifts carefully and thoroughly.

Any attempt to understand the titles “Son of Man” and “Son of God” must begin with the idioms and conceptual worlds of the Hebrew Bible, for it is here that these expressions first acquire meaning. Crucially, their earliest usages reflect the linguistic habits, theological commitments, and sociopolitical realities of Ancient Israel, and not the later messianic or Christological associations retroactively attributed to them by subsequent Jewish and Christian interpreters. Far from functioning as technical titles or doctrinal markers, each expression arises naturally from the narrative, poetic, and liturgical fabric of Israel’s Scriptures, bearing meanings that are at once modest, relational, and embedded in the cosmology of the Ancient Near East.
A. “Son of Man” in Ancient Israel
The phrase “son of man” (Hebrew ben ʾadam) belongs to the sphere of human anthropology in the biblical imagination. It is neither a titular designation nor an honorific, but rather an idiomatic way of referring to a mortal human being. The idiom parallels the broader ANE linguistic contrast between divine beings, who possess permanence or transcendence, and human beings, who are characterized by frailty, finitude, and dependency. In Mesopotamian and Egyptian literature alike, humans are regularly described in terms that highlight their limited lifespan, their creatureliness, and their subordination to the gods. Israel participates in this tradition but reframes it around the singular sovereignty of Yahweh and the covenantal relationship binding God and people.
This anthropological usage is seen most clearly in the prophetic literature, especially the book of Ezekiel, where the prophet addresses himself (or is addressed by) nearly one hundred times as the “son of man.” The expression serves not as a title of elevation but as a reminder of Ezekiel’s mortal status over against the majesty and agency of Yahweh. The repeated address underscores the asymmetry between human messenger and divine speaker, emphasizing that the prophet’s authority derives wholly from the God who commissions him.
Ezekiel, where God repeatedly calls the prophet “son of man” (more than 90 times). Here, ben ʾadam emphasizes the prophet’s mortality and creatureliness in contrast to the divine voice addressing him.
In wisdom and poetic texts, the idiom preserves this meaning. Psalm 8.4, for example, sets “man” and “son of man” in parallel as designations for humanity as a whole, evoking its insignificance in the cosmic scale and its surprising dignity in being remembered by God. Nowhere in the Hebrew Bible does ben ʾadam function as a messianic or eschatological title; nor does it bear any of the later theological freight connected to Jesus’ human nature. Its meaning is humble, descriptive, and rooted in a contrast between divine transcendence and human finitude.
Wisdom literature and various poetic texts (e.g., Ps 8:4), where “son of man” stands parallel to terms meaning human, mortal, or frail creature. In other words, the Old Testament usage is overwhelmingly anthropological, not messianic, and certainly not metaphysical. The idiom functions as a way of saying: “You, human creature - are finite, mortal, vulnerable.”
There is no hint, in Israel’s earliest traditions, of “Son of Man” as a divine figure, an eschatological figure, or a title referring to the Messiah. No Jewish interpreter prior to the post-exilic period seems to have understood the phrase in any extraordinary or exalted sense.
B. “Son of God” in Ancient Israel
Israel
In dramatic contrast, the expression “son of God” (ben ʾelohim, benê ʾelohim) operates in an entirely different conceptual register. Unlike “son of man,” which denotes creaturely limitation, “son of God” evokes divine status, relationship, and vocation. Its earliest and most significant usage is collective, not individual:
In Exodus 4.22, Israel is designated as Yahweh’s “firstborn son,” a metaphor articulating the nation’s chosen status and covenantal intimacy.
Hosea 11.1 reiterates this motif by recalling God’s deliverance of “my son” from Egypt. Here sonship expresses belonging, divine favor, and covenant identity, not metaphysical sonhood nor any humanized-ontological participation in divinity.
Divine Councils, Angels
A second major usage appears in the divine council traditions, where the “sons of God” refer to the heavenly beings who surround Yahweh and execute his purposes. This usage is encountered in: Job 1-2 and echoed in certain psalms (Ps 89), derives from a wider ANE cosmology in which high gods preside over assemblies of subordinate deities or celestial messengers. Israel’s monotheizing tendencies gradually transform this imagery, subordinating the “sons of God” as angelic servants, rather than divine peers, yet the terminology persists as a vestige of earlier mythic structures.
Kings
A third, and most consequential usage for later developments, is the royal usage. Within Ancient Near Eastern royal ideology, kings were regularly described as sons of a deity, whether by divine birth, adoption, or election. Israel adopts this political theology but adapts it to its unique covenantal monotheism.
In passages such as 2 Samuel 7.14 and Psalm 2.7, the Davidic king is named God’s “son” at his enthronement, an act of symbolically adopting the king as Yahweh’s representative on earth. This sonship is legal and relational, rooted in covenantal commitment and royal obligation. The king is not divine; he is chosen. He is not begotten from eternity; he is “begotten” on the day of coronation, meaning installed, affirmed, and empowered to rule as Yahweh’s vicegerent:
Psalm 2:7 proclaims: “You are my son; today I have begotten you.”
2 Sam 7:14 says of the Davidic king: “I will be his father, and he shall be my son.”
This is royal, adoptive language. The king is “begotten” on the day of enthronement, not from eternity. The title expresses legitimacy, vocation, God's paternal favor, the covenant with David.
Summary
Thus in Israel:
-
“Son of Man” = human being
-
“Son of God” = king, angels, or Israel itself; conveys role, relationship, or status
Neither title functions as a metaphysical category (ontological identity).
Nor does either title anticipate Nicene Christology.
It is essential to underscore what these usages do not mean. Nowhere in the Hebrew Bible does “son of God” indicate ontological divinity, metaphysical preexistence, or participation in a Trinitarian relation. Such meanings arise only in the theological imagination of later Christian centuries.
Likewise, “son of man” never denotes a heavenly redeemer, messiah, or divine-human figure; it signifies only humanity, often with emphasis on its limitations or vulnerability.
Thus, by the close of the monarchic and early exilic periods, the semantic landscape is unambiguous. “Son of Man” refers to a mortal human, typically in contrast to divine sovereignty. “Son of God” refers either to Israel as God’s covenant partner, the Davidic king as God’s anointed representative, or the members of the divine council.
Neither term points forward in any direct sense to the Christological interpretations later associated with Jesus; neither anticipates Nicene metaphysics or Chalcedonian formulations. Instead, each expression reflects the lived religious world of Ancient Israel - one shaped by covenant, kingship, prophetic call, and an evolving monotheism that continued to negotiate its relationship with the sacred heritage of the broader Near East.
These early meanings constitute the baseline from which all later reinterpretations proceed. Only by grasping their original semantic fields can we appreciate the dramatic transformations they undergo in the exilic, post-exilic, and apocalyptic eras, and the even more radical reconfigurations they eventually receive within the Jesus movement and the emergent theology of the early church.
