Luke

Overview

Luke is the only New Testament author to give us a two-volume work: the Gospel of Luke and the Acts of the Apostles. Taken together, these writings constitute the largest single contribution to the NT canon — and they present, with remarkable consistency across both volumes, a Christological portrait that fits the Biblical Unitarian framework more closely than any other NT author. This is not a matter of isolated proof texts. It is the sustained pattern of Luke's language, from the annunciation in chapter one of the Gospel to Paul's speech before Agrippa at the end of Acts.

The Jesus of Luke-Acts is fully and consistently the exalted Son — supremely honoured, raised from the dead, enthroned at God's right hand, Lord of all peoples, appointed judge of the living and the dead. But he is always these things by God's action. God anoints him, God works through him, God raises him, God exalts him, God appoints him. The agency consistently runs in one direction: from the Father, through the Son. In neither volume does Luke identify Jesus as God himself, and in neither does he require belief in Jesus's divine nature as a condition of salvation. The kerygma — the core proclamation — that Luke records across dozens of speeches and contexts is the message about a man whom God has acted through and upon. That pattern is consistent enough to be called a theological position, not merely an argumentum ex silentio.

Luke also grounds Jesus firmly in the story of Israel. His Jesus is the fulfilment of prophetic expectation — a Spirit-filled prophet like Moses, the Davidic king, the Isaianic servant who brings salvation to the ends of the earth. The prophetic-messianic framework that organises Luke-Acts is not a lower-register placeholder for something more metaphysical; it is the framework Luke consistently uses to explain who Jesus is and why it matters. The God of Abraham, Isaac, and Jacob is the God who did this.

Son of the Most High

Luke's Christological framework is set from the very first chapter of the Gospel. When Gabriel announces Jesus's birth to Mary, he uses two parallel phrases across two verses — and the parallelism is revealing. In Luke 1:32, Gabriel says: "He will be great and will be called the Son of the Most High." In Luke 1:35, he adds: "The Holy Spirit will come upon you... therefore the child to be born will be called holy — the Son of God."

Luke's own gloss on the title "Son of God" is "Son of the Most High." The Most High (ho Hypsistos) is a well-established Jewish divine title — the God of Israel at the apex of all things. The son is the son of him. Luke is not saying that Jesus is the Most High, but that he stands in a uniquely close relationship to the one who is. The frame is one of supreme honour combined with derivation: the son is exalted above all others precisely because he belongs to the one who is above all. This is the implicit hierarchy that runs through the whole of Luke-Acts — the Son occupying the highest conceivable status short of the one from whom that status comes.

Luke 1:35 then specifies why this child will bear the title "Son of God." The Greek word dio — "therefore," "for this reason" — makes the causal chain explicit. The Spirit's overshadowing is the reason for the title; the miraculous conception is what grounds the sonship. Luke's logic is not "eternally begotten, therefore Son of God" but "born of the Spirit's power, therefore Son of God." The title is conferred because of a specific event, not because of a pre-existent metaphysical nature.

The Acts kerygma: what the early church actually proclaimed

The speeches in Acts are the single most important body of evidence for what the earliest Christian proclamation looked like. Whether these speeches preserve genuine pre-Lukan tradition or represent Luke's theological compositions, they reflect what Luke understood the apostolic kerygma to be — and that kerygma, surveyed across its many iterations, is strikingly consistent in its subordinationist structure.

The pattern that emerges from the major speeches is this: God is the subject, Jesus is the object of God's action, and the resurrection-exaltation is the event that confers his lordship. Not once does any speaker in Acts proclaim that Jesus is God, that he is co-equal with God, or that the correct theological response is to recognise his divine nature. What is proclaimed, repeatedly, is what God did with and through Jesus.

Peter at Pentecost (Acts 2:14–36)

Peter's Pentecost sermon is the foundational proclamation of Acts, and it opens with one of the most unambiguous subordinationist statements in the NT: "Jesus of Nazareth, a man (andra) attested to you by God with mighty works and wonders and signs that God did through him in your midst" (Acts 2:22). Jesus is "a man" — Peter chooses the unqualified human noun — and God is the one who performed the works through him. The preposition matters: God is the agent, Jesus the instrument of God's action.

The sermon proceeds: "This Jesus God raised up" (v.32). "Being therefore exalted at the right hand of God" (v.33). "God has made him both Lord and Christ, this Jesus whom you crucified" (v.36). The structure is consistently theocentric: God raises, God exalts, God makes. The lordship and messiahship of Jesus are presented as the outcome of God's action upon Jesus, not as inherent attributes of a divine being. The "right hand of God" location is crucial — it is the position of the highest imaginable honour in the heavenly court, but it is a position next to God, not identical with God.

Peter at Solomon's Portico (Acts 3:12–26)

In the second major speech, Peter addresses the crowd who has witnessed a healing and gives God, not Jesus, the credit. "The God of Abraham, the God of Isaac, and the God of Jacob, the God of our fathers, glorified his servant Jesus" (v.13). The title used here is pais — servant or child — drawn from the Isaianic servant tradition. It is a title of enormous honour and intimacy, but it is not the title of God himself. It is explicitly the title of one whom God glorifies.

Peter identifies Moses's prophecy of "a prophet like me" as pointing to Jesus (v.22), framing Jesus within Israel's prophetic tradition rather than outside or above it. The climax of the speech reaches forward to the restoration of all things "that God foretold by the mouth of all his holy prophets from of old" (v.21). God remains the one who plans and foretells; Jesus is the one through whom God fulfils. The speech closes: "God, having raised up his servant, sent him to you first" (v.26) — again, God as subject, Jesus as sent servant.

The early community's prayer (Acts 4:23–31)

Luke records the prayer of the earliest Jerusalem community after Peter and John's release, and its theological structure is striking. The community addresses "Sovereign Lord (Despota), who made the heaven and the earth" — God directly — and then refers to "your holy servant Jesus, whom you anointed" (v.27) and "the name of your holy servant Jesus" (v.30). This is not a community in the process of worshipping Jesus as God. It is a community that relates to God through Jesus. They pray to God, not to Jesus, and they invoke Jesus as God's anointed servant. The pais language appears twice — both times as a title that distinguishes Jesus from the God to whom the community prays.

Peter to Cornelius (Acts 10:34–43)

The Cornelius episode is one of the most significant in Acts — the first explicit Gentile conversion — and the Christological language of Peter's speech to Cornelius's household follows the same pattern. "God anointed Jesus of Nazareth with the Holy Spirit and with power. He went about doing good and healing all who were oppressed by the devil, for God was with him" (v.38). God anoints, God is with him — Jesus acts in the power God provides. "They put him to death by hanging him on a tree, but God raised him on the third day" (v.39–40). "He is the one appointed (hōrismenon) by God to be judge of the living and the dead" (v.42). The judicial authority Jesus holds is authority that has been appointed and conferred — it does not belong to him by virtue of being God, but by virtue of what God has given him.

Paul at Pisidian Antioch (Acts 13:16–41)

Paul's first synagogue sermon in Acts follows the same theological pattern as Peter's speeches. "Of this man's offspring God has brought to Israel a Saviour, Jesus, as he promised" (v.23). Jesus is descended from David as a man; he is a Saviour whom God has brought. The resurrection: "God raised him from the dead" (v.30). Then Paul applies Psalm 2:7 to the resurrection: "You are my Son; today I have begotten you" (v.33). The "today" of divine begetting is identified with the day of resurrection — a specific moment in history. This is not language about eternal generation or pre-existent sonship; it is language about what God did on a particular day to a particular man. Sonship, in Paul's Acts 13 sermon, is an event that happened in time, not a relationship that exists outside of time.

Paul at Athens (Acts 17:22–31)

Paul's Areopagus speech is addressed to a pagan Greek audience — the audience for whom, one might argue, a clear statement of Jesus's divine identity would be most relevant and intelligible. And yet Paul describes Jesus simply as "a man whom he [God] has appointed" (en andri hō hōrisen) — using the same word for divine appointment as Peter in Acts 10:42. The proof of this appointment is the resurrection: "he has given assurance to all by raising him from the dead" (v.31). The proclamation to Gentiles, no less than to Jews, is framed entirely in terms of what God has done with and through a man. No claim of Jesus's divine status, no Trinitarian explanation.

The servant (pais) language

One of the most consistent Christological titles in the early chapters of Acts is pais — translated "servant" or "child" — applied to Jesus by the earliest Jerusalem community. Acts 3:13 ("glorified his servant Jesus"), Acts 3:26 ("having raised up his servant"), Acts 4:27 ("your holy servant Jesus, whom you anointed"), Acts 4:30 ("the name of your holy servant Jesus"). This title derives from the Isaianic Servant Songs — the figure in Isaiah 42–53 who is chosen and upheld by God, anointed with the Spirit, and through whom God's salvation comes to the nations.

The pais title is highly honoured — it carries the weight of the entire Servant tradition — but it is irreducibly relational and derivative. A servant is not the master. A child is not the parent. The one whom God glorifies is not the God who glorifies. Luke applies this title consistently across the earliest community's self-understanding without any apparent sense that it requires qualification or supplementation by claims of divine identity. That is the Christology of the Jerusalem church as Luke records it: God's holy servant, anointed, sent, raised, glorified.

What Luke never says about salvation

Perhaps the most theologically significant aspect of Luke's Christology is not what he says but what he does not say. Across the entire two-volume work — Gospel and Acts — Luke never once presents belief in Jesus's divine nature as a condition of salvation. Not in the kerygma, not in conversion accounts, not in summaries of the gospel, not in pastoral instruction to new communities. The silence is not occasional or incidental. It is total and consistent.

The Pentecost sermon ends with the crowd asking "What shall we do?" and Peter's answer: "Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins" (Acts 2:38). Nothing about the Trinity. Nothing about Jesus's divine nature. Nothing about pre-existence. The Ethiopian eunuch asks what prevents him from being baptized and Philip's criterion is simply: "If you believe with all your heart, you may" — and what the eunuch confesses is that "Jesus Christ is the Son of God" (Acts 8:37), in the functional-messianic sense that runs throughout Luke-Acts. The Philippian jailer asks "What must I do to be saved?" and Paul's answer is: "Believe in the Lord Jesus, and you will be saved" (Acts 16:31). The content of that belief, in context, is the proclamation about a man raised by God.

Acts 4:12 — "there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved" — is sometimes read as bearing on Jesus's divine status. The verse itself states that salvation is found in no other "name" than Jesus's — Jesus the Messiah, raised by God. Trinitarian interpreters argue that this language of the exalted Name, especially read alongside Philippians 2:9–11 (where the "name above every name" echoes the divine name YHWH), invokes Jesus's divine identity; Biblical Unitarian interpreters respond that exclusivity of salvation through Jesus is fully compatible with the exalted-servant framework and does not require the claim that Jesus is God. The verse stands in a speech in which Jesus has just been called God's "servant" and "holy one" — a context that BU readers argue militates against a Trinitarian reading, though scholars like C. Kavin Rowe find high Christological claims operating at the narrative level throughout Luke-Acts even where functional language dominates.

This is not a small omission. If the correct understanding of Jesus's identity — that he is God the Son, co-equal and co-eternal with the Father — is necessary for salvation, then Luke's record of the apostolic mission is a catastrophic failure of communication. Missionary proclamation after missionary proclamation, conversion after conversion, with never a word about it. The most natural explanation is that Luke did not include Trinitarian theology in the kerygma because it was not part of the kerygma. The apostles proclaimed what they knew: a man whom God had raised and exalted to the highest position, through whom forgiveness and salvation were now available to all. That was the message. And it was enough.

Christological themes

What scholars debate

The key debate about Luke's Christology centres on whether his Spirit-language, agency-language, and servant-titles represent a genuinely "lower" Christology than John's or Paul's, or whether Luke is expressing the same high Christology in a different register. James D.G. Dunn (Christology in the Making) argues that the exaltation language in Acts reflects a stage of Christological development prior to pre-existence theology — the earliest kerygma understood Jesus's lordship as something conferred at the resurrection, not as a manifestation of an eternal identity. C. Kavin Rowe (Early Narrative Christology) contends that Luke's narrative identifies Jesus with YHWH through subtle literary patterns — the application of kyrios passages from the LXX to Jesus, the way Luke describes Jesus's authority over nature and demons — so that the functional language is in service of a high Christological claim made implicitly at the narrative level. Joseph Fitzmyer (The Gospel According to Luke, Anchor Bible) mediates: Luke's Christology is high but expressed in functional rather than ontological categories, which does not resolve whether the ontological claim is present by implication or absent by design.

The question of the Acts speeches is central. Are they early pre-Lukan tradition, genuine historical memory of what Peter and Paul said, or Luke's own theological compositions? Darrell Bock (Acts, BECNT) argues that they reflect genuine early tradition which Luke has shaped but not invented, and that the exaltation language describes Jesus's messianic installation rather than implying he was not already God's Son. Martin Hengel similarly saw the speeches as preserving very early Christological formulas. But even if the speeches are early, their content is what it is: "a man attested by God," "God's holy servant," "a man whom God appointed." Whether that represents the limits of the earliest community's Christology, or the floor beneath which Luke will not go while implying more, is precisely what is at stake.

The most pointed challenge for Trinitarian interpreters of Luke-Acts is the salvation question. If the Nicene definition — that the Son is co-equal and co-eternal with the Father, of one being with him — captures something essential to the Christian proclamation, why does Luke's record of that proclamation, across dozens of speeches to diverse audiences over the entire span of the early church's mission, never include it? The Trinitarian responses are available: Luke may be abbreviating, his audience may have understood more than is explicit, the ontological claim may be latent in the functional language. But the burden of explanation sits with those who would add to Luke what Luke does not say.
