The Sermons of Acts: A Man Attested by God
"Men of Israel, hear these words: Jesus of Nazareth, a man attested to you by God with mighty works and wonders and signs that God did through him in your midst, as you yourselves know..." — Acts 2:22
I. Opening the Dossier
For fourteen studies, this series has been quoting the sermons of Acts piecemeal — a verse from Pentecost here, a clause from Cornelius' house there — the way one cites exhibits during a long trial. The time has come to open the whole dossier and read it as a dossier: every recorded evangelistic sermon of the founding apostles, from the first Pentecost to the Areopagus, surveyed as a single body of evidence.
The question we bring to it is simple and enormous: when everything was at stake — when Peter stood before the crowd that had crucified his Lord, when Paul stood before pagan philosophers who had never heard the name — what did they actually say? What was the gospel, as the gospel was first preached?
The answer, we will find, is remarkably consistent from sermon to sermon, city to city, apostle to apostle, audience to audience. It is a gospel with one divine Actor and one attested Man: the God of Israel — who promised, sent, anointed, accompanied, delivered up, raised, exalted, and appointed — and Jesus of Nazareth, the man in whom every one of those verbs found its object. It is, in other words, the gospel this whole series has been reconstructing — preached by the people who were there.
One note on method before we begin, because the argument of this study includes an argument from absence, and such arguments must be framed with care. We will not claim that silence in general proves anything. We will claim something bounded and specific: these sermons are Luke's inspired summaries of the evangelistic message itself — the proclamations that created the church, each ending in explicit demands ("repent and be baptized"; "believe") and each producing saved communities on the spot. If any confession is essential to salvation, this is the one place in all Scripture where it could not be omitted — not once, and certainly not every time. What the sermons uniformly say, and uniformly do not say, is therefore evidence of the highest order about the content of saving faith as the founders understood it.
Scholarship has long observed that the sermons share a fixed skeleton — C. H. Dodd's classic study of the apostolic kerygma (proclamation) traced it decades ago: the promises are fulfilled; Jesus ministered, attested by God; he was killed by lawless hands, within God's set plan; God raised him; God exalted him to his right hand; we are witnesses; therefore repent. Keep that skeleton in view; we are about to watch it walk through eight rooms.
II. Pentecost: The Grammar of the Gospel (Acts 2)
The church's first sermon deserves a full grammatical audit, because its pattern governs everything after it. Read it with a pencil, underlining the subject of every saving verb:
"Jesus of Nazareth, a man attested to you by God (anēr apodedeigmenos — a man accredited, certified) with mighty works and wonders and signs that God did through him in your midst... this Jesus, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. God raised him up, loosing the pangs of death... This Jesus God raised up, and of that we all are witnesses. Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this that you yourselves are seeing and hearing... Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified." (Acts 2:22–24, 32–33, 36)
Audit complete: God attested. God did the works through him. God's plan delivered him up. God raised him. God exalted him. He received from the Father. God made him Lord and Christ. In the founding sermon of Christianity, God — the Father — is the subject of every saving verb, and Jesus is the man in whom the verbs land. The sermon's opening formula is its thesis: a man attested by God. Its climax is a conferral: God made (epoiēsen) him Lord and Christ — the enthronement of Study 8, preached — and the "Lord" is defined by the sermon's own proof-text, Psalm 110:1, where Yahweh speaks to David's lord, adoni, the exalted human superior (Study 1). Even the Spirit's outpouring — sometimes urged as an unshared divine prerogative — is narrated by Peter with the mechanics attached: having received from the Father... he has poured out (Studies 2 and 11). Received, then given: the cascade, from the first sermon.
And what does this gospel demand? "Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins" (2:38). Three thousand obeyed and were saved that day — on this message, with these verbs, and no others.
III. The Portico and the Prayer: God's Servant (Acts 3–4)
Weeks later, at Solomon's Portico, Peter preaches again — and opens by planting the sermon inside Israel's oldest confession:
"The God of Abraham, the God of Isaac, and the God of Jacob, the God of our fathers, glorified his servant (pais) Jesus... you killed the Author of life (archēgos), whom God raised from the dead... God, having raised up his servant, sent him to you first, to bless you by turning every one of you from your wickedness." (Acts 3:13, 15, 26)
The covenant God of the patriarchs (Studies 6 and 8) has glorified his servant — and the title is chosen with prophetic precision: pais (παῖς, G3816) is the Septuagint's word for the Isaianic Servant: "Behold, my servant... I have put my Spirit upon him" (Isa 42:1 — the baptismal voice, Study 11); "Behold, my servant... shall be exalted and lifted up" (Isa 52:13). The Portico sermon is Servant-song exposition: Yahweh's pais, rejected, vindicated, exalted — exactly per the script. Twice in this sermon (3:13, 26), twice in the church's Psalm-2 prayer that follows ("your holy servant Jesus, whom you anointed," 4:27, 30 — Study 9), the earliest church's favorite title for its Lord is God's Servant. And here too Peter reaches for Deuteronomy 18 — "Moses said, 'The Lord God will raise up for you a prophet like me from your brothers'" (3:22; Study 7) — and springs the raised-up wordplay on the resurrection (3:26). "Author of life" (archēgos, ἀρχηγός, G747 — pioneer, founder, trailblazer) is a staggering title, and the sermon immediately supplies its grammar: the Author of life is the one "whom God raised from the dead" — the pioneer through whom God's life now flows, the firstborn from the dead walking point for the family. Before the Sanhedrin days later, the formula holds: "The God of our fathers raised Jesus... God exalted him at his right hand as Leader (archēgos again) and Savior" (5:30–31) — even Savior arrives by exaltation: God, the ultimate Savior (Isa 43:11), giving his people a Savior as he had in the days of the judges (Judg 3:9, 15; Neh 9:27), now supremely.
IV. Stephen: The Kerygma in a Snapshot (Acts 7)
Stephen's speech is a covenant-history indictment rather than an evangelistic sermon, but its ending gives us something better than a sermon: the kerygma as an eyewitness vision.
"But he, full of the Holy Spirit, gazed into heaven and saw the glory of God, and Jesus standing at the right hand of God. And he said, 'Behold, I see the heavens opened, and the Son of Man standing at the right hand of God.'" (Acts 7:55–56)
Readers of Study 2 have stood at this window before. Stephen sees two: the glory of God, and the man — the Son of Man of Daniel 7 — at his right hand. Not a triune vision; not the Son within the glory; the exalted human vice-regent beside the enthroned God, exactly as Psalm 110:1 seated him and every sermon has preached him. And then, dying under the stones, Stephen entrusts himself to the King he is looking at: "Lord Jesus, receive my spirit" (7:59). We will weigh this prayer honestly in the Steel Man; note here only what the vision itself establishes — the martyr's last address is directed to a visibly enthroned figure standing in a specified location: at the right hand of God. Stephen's eyes supply Stephen's theology.
V. Cornelius: The Same Sermon for the Gentiles (Acts 10)
If the Jewish sermons were tactically simplified for monotheists, the Gentile Pentecost is where the fuller message should surface. Instead, in the house of Cornelius, Peter preaches the identical gospel — including the verse this series has leaned on since Study 2:
"...how God anointed Jesus of Nazareth with the Holy Spirit and with power. He went about doing good and healing all that were oppressed by the devil, for God was with him... They put him to death by hanging him on a tree, but God raised him on the third day and made him to appear... And he commanded us to preach to the people and to testify that he is the one appointed (horizō) by God to be judge of the living and the dead." (Acts 10:38–42)
God anointed. God was with him. God raised him. God appointed him judge. The Christology of this sermon is not low — hear it at full height: this man will judge the living and the dead; every human being who has ever drawn breath will stand before him. But the height is conferral all the way up: appointed — the same verb (horizō, ὁρίζω, G3724) Paul uses for the resurrection-enthronement in Romans 1:4 (Study 8). And "everyone who believes in him receives forgiveness of sins through his name" (10:43): the demand, once more, complete — and the Spirit falls on the household mid-sermon, heaven's own amen to the message as preached.
VI. Pisidian Antioch: Paul's Fullest Sermon (Acts 13)
Was this pattern merely Petrine? Luke gives us Paul's most extensive recorded synagogue sermon, and the skeleton is bone-for-bone the same: covenant history, the Baptist, the crucifixion by ignorant rulers "according to plan," and then the drumbeat — "But God raised him from the dead" (13:30) — driven home with the texts this series studied at the coronation: "this he has fulfilled to us their children by raising Jesus, as also it is written in the second Psalm, 'You are my Son, today I have begotten you'" (13:33 — Ps 2:7's "today" dated to Easter; Studies 8–9), with "the holy and sure blessings of David" (13:34; Isa 55:3) securing the covenant chesed. And the offer: "Let it be known to you therefore, brothers, that through this man forgiveness of sins is proclaimed to you, and by him everyone who believes is freed" (13:38–39). Through this man. Paul's own summary phrase for his own gospel's mediator — in a sermon that ends with a congregation begging to hear more.
VII. The Two Pagan Test Cases: Lystra and Athens (Acts 14, 17)
Now the decisive experiments — because with pagan audiences, every tactical explanation for the sermons' pattern can be tested against hearers who had no monotheistic scruples to accommodate.
Lystra. Paul heals a man lame from birth, and the crowd reaches instantly for the category their culture kept oiled and ready: "The gods have come down to us in the likeness of men!" (14:11). Barnabas becomes Zeus; Paul, Hermes; the priest brings oxen and garlands for sacrifice. Here is the incarnate-god category, offered unprompted, with worship attached. And the apostles' response is the most violent emotional reaction recorded of them anywhere:
"When the apostles Barnabas and Paul heard of it, they tore their garments and rushed out into the crowd, crying out, 'Men, why are you doing these things? We also are men, of like nature with you, and we bring you good news, that you should turn from these vain things to a living God, who made the heaven and the earth and the sea and all that is in them.'" (14:14–15)
Torn garments — the gesture reserved for blasphemy. The apostles possessed the god-in-human-form category, met it face to face, and tore their clothes at it, preaching the Creator against it. (Let it be said carefully: the point here is not to associate any Christian tradition with paganism — it is strictly evidential: the category was available, recognized, and refused, which bears directly on whether its absence from the sermons is tactical or doctrinal.) Peter had done the same in miniature at Cornelius' door — "Stand up; I too am a man" (10:26) — and the angel of Revelation twice likewise ("You must not do that!... Worship God," Rev 19:10; 22:9). The apostolic reflex against creature-deification was total.
Athens. Then the Areopagus — the one audience on earth for whom "God became man" would have been easy, familiar, even attractive. Paul preaches the Creator who needs nothing, allots the nations their times and boundaries (17:26 — the Deut 32 worldview of Study 5, preached to Greeks), and calls all people everywhere to repent —
"...because he has fixed a day on which he will judge the world in righteousness by a man whom he has appointed (horizō); and of this he has given assurance to all by raising him from the dead." (17:31)
By a man whom he has appointed. Standing before hearers who would have received a divine visitor without blinking, Paul's summary of the coming judgment names its agent with the same word every sermon has used: a man — appointed, accredited by resurrection. The pattern is not an accommodation to the audience; it survives the total inversion of the audience. It is the doctrine.
VIII. The Composite: What They Said, and What They Never Said
Lay the dossier's pages side by side, and the composite portrait assembles itself.
The verbs, with one subject. God attested (2:22); did the works through him (2:22; 10:38); planned and delivered him up (2:23; 4:28); raised him (2:24, 32; 3:15, 26; 4:10; 5:30; 10:40; 13:30, 33, 37; 17:31); exalted him (2:33; 5:31); glorified him (3:13); anointed him (4:27; 10:38); was with him (10:38); made him Lord and Christ (2:36); appointed him judge (10:42; 17:31); sent him to bless (3:26); gave him assurance before all (17:31). One grammatical subject saves the world in the book of Acts, and it is God, the Father.
The titles, all conferred, all exalted. Man. Servant. Prophet like Moses. Christ. Lord (adoni, by making). Leader-Pioneer. Savior (by exaltation). Son of God (by the decree of Ps 2:7, dated to Easter). Judge of the living and the dead (by appointment). This is not a "low" Christology — it is conferral at maximum altitude: the sermons place every knee and every verdict before this man. But every title has a Giver, and every height a Hand that raised him to it.
The absences. In no sermon is Jesus called God. No sermon preaches an incarnation, two natures, or a descent from a prior heavenly life. No sermon demands, as a condition of salvation, any confession about Jesus' deity. And the demands are stated, every time: repent; be baptized in his name; believe that God raised him; receive forgiveness through his name (2:38; 3:19; 10:43; 13:38–39; 17:30). When Paul later crystallizes the saving confession in his epistles, it matches the dossier exactly: "if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved" (Rom 10:9) — two clauses, both preached in every city of Acts, neither a deity-claim: the conferred Lordship, and the Father's act.
IX. Engaging the Traditional View
1. The Steel Man
The traditional account of this evidence runs along two well-built roads. The first is pedagogical accommodation: the sermons are evangelistic first contact — the kerygma's "milk" — addressed either to strict Jewish monotheists, for whom the mystery of Christ's deity had to be approached gradually, or to raw pagans, for whom it had to be distinguished from their mythology; the fuller doctrine was unfolded later, in the church's teaching and the epistles, on the sound missionary principle of one truth at a time. Luke's accounts, moreover, are compressed summaries — a few hundred words standing for longer addresses — and summaries omit. The second road finds high Christology already implicit within the sermons: Peter's Pentecost text promises that "everyone who calls on the name of the Lord shall be saved" (2:21, quoting Joel, where the Lord is Yahweh) — and the sermon issues in baptism in the name of Jesus (2:38), with the church soon defined as those who "call on his name" (9:14; 22:16); the outpouring of the Spirit (2:33) is elsewhere God's own act; "the Author of life" (3:15) is a title of staggering reach; and Stephen, at the hour when a Jew commits his spirit to God alone (Ps 31:5), prays "Lord Jesus, receive my spirit" (7:59) — invocation of Jesus in the manner of prayer. These arguments are made by careful scholars, motivated honorably: to read Acts in harmony with the whole canon as the tradition understands it, and to take seriously that Luke himself elsewhere records exalted things. The case deserves a full hearing, and its strongest exhibits — Joel's name, and Stephen's dying prayer — deserve particular respect.
2. The Tension
Yet each road, walked to its end, arrives at difficulty. The pedagogy explanation inverts both missionary situations it invokes. For Jewish hearers, a deity-claim about Jesus would have been not a refinement to defer but the decisive issue to address — the one matter on which a Shema-confessing audience could not be left uninformed while being baptized into his name; deferring it would not be gentle pedagogy but material misrepresentation of the confession's object. And these preachers were manifestly not managing offense: they indicted their hearers for the murder of God's servant to their faces (2:23, 36; 3:14–15) and accepted floggings rather than soften a syllable (5:40–42). For pagan hearers the tactical logic runs backward entirely: Lystra proves the Greco-Roman world would supply the incarnate-god category unprompted and enthusiastically (14:11) — so if that category were the message, Athens and Lystra were the easiest rooms the apostles ever entered; instead they tore their garments at it in one city and, in the other, summarized the eschaton as judgment "by a man whom he has appointed." An omission that persists when the audience would resist the doctrine and when the audience would welcome it is not tracking audiences; it is tracking doctrine. The summaries-compress point is fair in general — but it must face Luke's presentation of these summaries as salvifically complete: each carries the gospel's full demands, each produces saved communities, and the demanded confession never includes the allegedly essential article — a pattern across every sermon, both apostles, and every audience type, which compression cannot explain. The implicit-deity exhibits, examined in their own sentences, resolve one by one. The Lordship of 2:36 is defined by the sermon that proclaims it: "God has made him both Lord and Christ," on the warrant of Psalm 110:1, whose "my lord" is adoni — the exalted creaturely superior (Study 1); calling on the name of this Lord is calling on the name he bears by gift — "your name, which you have given me" (John 17:11; Study 13), "the name that is above every name" bestowed at exaltation (Phil 2:9) — Joel's salvation administered through God's plenipotentiary, exactly as the Horeb charter provided (Deut 18:19; Study 7). The Spirit-pouring of 2:33 states its own mechanics in the clause the objection must skip over: "having received from the Father... he has poured out." The archēgos of 3:15 is the pioneer-founder whom the verse's own next words locate: "whom God raised from the dead" — the trailblazer of the life God gives. And Stephen: his prayer must be read with his eyes — he is addressing a figure he sees, "the Son of Man standing at the right hand of God" (7:56), a vision that is itself the kerygma's diagram: two figures, God and the exalted man beside him. Entrusting one's spirit to the visibly enthroned King whom God appointed judge of the living and the dead (10:42) is Psalm 2 piety — the kiss rendered to the Son (Ps 2:12; Study 9), homage that honors the Father who installed him (John 5:23) — the martyr dying exactly inside the theology of the sermons, not outside it. The dossier, cross-examined, does not crack; it clarifies.
3. The Resolution
The gospel of the founding era emerges from the survey whole, coherent, and radiant — and it is the gospel this series has been assembling from Genesis onward. The God of Israel — the only true God of the Messiah's own creed (Study 13), the Creator preached at Lystra and Athens, the covenant God of the patriarchs invoked at the Portico — has acted: attesting, anointing, accompanying, planning, raising, exalting, appointing. And Jesus of Nazareth is the man in whom he acted: the Servant glorified, the Prophet raised up, the Son enthroned by decree on Easter morning, the Lord seated at the right hand, the Judge before whom the world will stand, the name through which forgiveness flows. Nothing in this gospel is diminished — it is the highest account of a human being ever proclaimed, and it commands repentance from all people everywhere. And nothing in it disturbs the Shema — indeed it is the Shema, in missionary motion: one God, repossessing his world through the man he appointed. The church that wants apostolic results might begin by preaching the apostolic sermon; and the church that wants to know what confession saves may read it from the dossier's every page: Jesus is Lord — and God raised him from the dead.
X. Preaching What They Preached
Recover the kerygma's confidence. The founders' gospel fit in a few hundred words, made no philosophical demands its hearers could not follow, and turned the world upside down. Promises kept; a man attested; a death within the plan; God raised him; a Lord enthroned; a Judge appointed; therefore repent. Every believer can carry that sermon whole — to a neighbor, a colleague, a child.
Let God be the hero of your testimony. The sermons' grammar is a discipline for ours: God the subject, his Christ the appointed one, ourselves the witnesses. Evangelism bends toward manipulation when we become the protagonists; it recovers its power when, like Peter, we simply report what God has done.
Honor the Son as the sermons do. Nothing in this study lowers Jesus by a hair's breadth — the dossier crowns him Judge of the living and the dead. Render him the kiss of fealty (Study 9), call on his name, obey him as Lord — and in doing so, honor the Father who made him both Lord and Christ (John 5:23).
Hear, O Israel: Yahweh our God, Yahweh is one — one God who kept every promise; one man attested, anointed, raised, and enthroned; one sermon, preached from Jerusalem to Athens without a syllable of retreat; and one summons, as current now as at the first Pentecost: Repent, and be baptized in the name of Jesus Christ for the forgiveness of your sins — for the promise is for you and for your children and for all who are far off.
