13A. The Gospel of Teshuvah: Luke and the Messiah Who Called the World to Repentance

Finding Injil: What Were the Ṣaḥīḥ Hadith of the Messiah?
New manuscript chapter, 31 October 2026

Which Gospel does the Qurʾān send us to read?

The alleged Islamic dilemma usually begins by identifying the Injīl with the New Testament and then identifying the New Testament with the faith of the councils. The Muslim is told that the Qurʾān confirms the Gospel, that the Gospel teaches the divinity of Christ, and that the Qurʾān therefore confirms the very doctrine it rejects. The argument arrives at Nicaea before anybody has opened Luke.

I have spent much of this book explaining why the Fourth Gospel deserves serious attention. The promised figure in John 16 has made that investigation unavoidable, and John 1 raises a real question about the Word whom God sends into the world. Yet the instruction in Qurʾān 5:46–48 concerns revelation given to Jesus and the obligation of its people to judge by what God revealed. The text names the Injīl. It does not announce a fourth-century creed as the criterion for recovering the Messiah's religion.

The question turns instead on the content of the message. What did Jesus call people to do? What did he say God would forgive? What sort of person becomes fit to receive the Kingdom? The Gospel of Luke gives those questions a force that our earlier Synoptic comparison treated far too briefly.

Luke contains a Gospel of return. Its tax collectors restore what they have taken. The wealthy are ordered to open their hands. A father receives the son who has wasted his inheritance. A condemned man is promised a place with Jesus, and an unjust execution becomes a summons to repent. The Acts of the Apostles continues this account of forgiveness in the proclamation of a risen Messiah.

The Jewish word teshuvah, return, gives this movement its proper background. Hebrew Scripture calls wrongdoers to turn from violence, repair injustice, and seek the mercy of God. Luke's Greek vocabulary of metanoia, repentance, and epistrophē, turning, develops the same practical concern within its own story. The correspondence is conceptual and scriptural; it is not evidence that Jesus or Luke pronounced the later technical rabbinic formulas word for word.

I want to recover that Gospel before assigning its author the theology of Paul or the metaphysics of Nicaea. Luke makes the problem more interesting because his companion volume, Acts, spends much of its time vindicating Paul. The writer who defended Paul's mission nevertheless gave us a salvation narrative with a different center of gravity from the account of the cross in Paul's surviving letters.

The Baptist: repentance you can measure

Luke announces his moral program before Jesus begins his public ministry. John the Baptist calls for a baptism of repentance connected with the forgiveness of sins (Luke 3:3). When the crowd asks what repentance requires, he answers with instructions capable of being obeyed that afternoon.

Whoever has two tunics must share with someone who has none. Whoever has food must do likewise. Tax collectors must take only what is authorized. Soldiers must abandon extortion, false accusation, and exploitation of their position (Luke 3:10–14).

These commands describe the return of ordinary economic and civic relationships to justice. A person's changed relation to God becomes visible in how he treats someone vulnerable to his power. The question of forgiveness immediately acquires a material dimension.

The comparison with Jewish scripture is direct. Isaiah 1:16–18 orders its audience to cease evil, seek justice, rescue the oppressed, defend the orphan, and plead for the widow; the promise of cleansing follows the summons. Ezekiel 18:21–32 describes a wrongdoer turning from his sins and doing what is just and right. God takes no pleasure in the death of the wicked and summons them to live. The later Jewish language of teshuvah develops precisely this nexus of return, repentance, and restored conduct.

Leviticus 5:20–26 in Hebrew numbering, commonly 6:1–7 in English, and Numbers 5:6–7 add restitution and confession to the treatment of dishonest gain. The texts belong to a cultic world that still knows sacrifice. Their moral structure prevents sacrifice from substituting for the repair of an identifiable injury.

This matters for the contrast with Mark. Mark also opens with John's baptism and his proclamation of repentance (Mark 1:4). The tradition of return therefore precedes Luke's literary intervention. Luke expands the Baptist's message into a direct social instruction and gives us a particularly concrete account of its fruit. The difference is in the space the evangelist devotes to making repentance visible.

The Baptist's hearers are already members of a religious society. They ask what to do, and the answer addresses food, clothing, wages, and force. There is no passage through a doctrine of a second divine person before they are allowed to begin obeying God.

Good news for the poor

In Luke 4:16–21 Jesus reads Isaiah at Nazareth. The Spirit of the Lord has anointed him to announce good news to the poor, liberty to captives, sight to the blind, and release to the oppressed. He declares the scripture fulfilled in their hearing. The passage draws especially on Isaiah 61:1–2 and 58:6. Its imagery belongs to liberation, restoration, and a divine appointment expressed in acts among human beings.

The word translated release, aphesis, can denote release from captivity or debt as well as forgiveness of sins in other contexts. The resonance matters to a Gospel in which poverty and exclusion repeatedly become questions of salvation. We should avoid flattening every use of the word into one technical theory of atonement.

Luke's Beatitudes address the poor directly (6:20) and attach corresponding woes to the wealthy (6:24–26). Matthew's familiar formulation blesses the poor in spirit. The differing wording reflects a change in the represented audience and its moral urgency. Luke's hungry receive a promise of satisfaction; the satiated are warned. The text concerns the distribution of comfort and the coming reversal of fortunes.

The pattern continues in the parable of the rich man and Lazarus (Luke 16:19–31). The gulf between them in the afterlife exposes a social gulf that the rich man left untouched in life. The parable's closing appeal to Moses and the prophets gives the ethical accusation a scriptural foundation. The wealthy man's brothers already possess the instruction they need.

Another rich man receives an even more direct warning. In Luke 18:18–30, Jesus instructs a ruler to sell what he has and distribute it to the poor. The command is embedded within a discussion of entering life and the Kingdom. The attachment to possessions obstructs the response Jesus demands.

Luke knows forms of wealth used in support of the community. His concern is moral responsibility rather than a mathematical prohibition on possessing anything. The repeated warnings nevertheless make the rich person's relation to the poor a central part of the narrative's theology.

The Qurʾānic comparison is immediate. Sūrat al-Māʾida links right belief with righteous action in 5:69. Sūrat al-Balad describes the difficult path through freeing the enslaved and feeding people in hunger (90:11–16). Sūrat al-Māʿūn condemns those who deny judgment while neglecting or repulsing the vulnerable (107:1–7). Luke's account of good news to the poor belongs in conversation with these passages because each gives material content to religious fidelity.

Zacchaeus and the arithmetic of forgiveness

The clearest example is the story of Zacchaeus (Luke 19:1–10). He is a chief tax collector and wealthy. His work places him inside a revenue system in which opportunities for exploitation are obvious. Jesus chooses to stay at his house, and the crowd protests that he has gone to a sinner.

Zacchaeus responds by giving half his possessions to the poor and promising fourfold repayment to anyone he has defrauded. Jesus declares that salvation has come to the house and describes his mission as seeking and saving what was lost.

The order is theologically revealing. The narrative gives Jesus's recognition of the man, Zacchaeus's declaration about property, and the announcement of salvation. The sinner becomes visible through what happens to his wealth.

The Greek verbs in 19:8 are present forms: didōmi, I give, and apodidōmi, I repay. Scholars debate whether the words describe an existing habit or constitute a public pledge beginning now. The future-directed reading fits the narrative of a man receiving Jesus amid the crowd's accusation. Ladislav Tichý's grammatical study argues for this understanding, while other interpreters defend a customary sense that would vindicate Zacchaeus against the crowd. Under either reading, the economic conduct is central evidence in Luke's account of this man.

The fourfold repayment carries biblical legal associations. Exodus 22 distinguishes restitution according to the offense, while Leviticus and Numbers require acknowledgment and repair for dishonest gain. Zacchaeus's response exceeds the simplest available repayment requirement. It is repentance with an account ledger.

This is the Jewish language of return made practical. One who has taken from another cannot complete his return simply by announcing a new conviction while keeping the proceeds. The injured person has a claim.

Here a theological system that treats salvation solely as the cancellation of a penalty by an innocent third party leaves out much of Luke's narrative. Jesus recognizes transformation in the relationship between a wrongdoer, his neighbors, and God. The text gives the reader specific grounds on which to recognize it.

The ethical analogy with Islamic repentance follows naturally. Tawbah requires turning away from wrongdoing. Where the wrong concerns another person's property, restitution becomes part of the moral question. This common structure is more illuminating than an argument about whether one scripture has already certified the entirety of another religion's later creed.

The father who runs to meet his son

Luke 15 gives the argument a domestic image. A younger son demands his share of his father's property, leaves home, wastes his inheritance, and is reduced to hunger. He prepares a confession and returns. His father sees him from a distance, runs to embrace him, and restores him to the household. The elder son's resentment brings the question of justice and mercy into the family itself.

The father initiates the welcome before the younger son can complete his prepared speech. The son's decision to return still belongs to the narrative. The story stages divine mercy as the restoration of a relationship broken by waste, estrangement, and self-ruin.

A transactional theory of forgiveness has difficulty becoming the plot of this parable. The father gives no account of an innocent substitute against whom the younger son's penalty is charged. The cost of the son's waste was real. The father chooses the restoration of his child, and the elder son is invited to rejoice at the recovery of someone lost.

There are Jewish antecedents for the language and imagination. Hosea 14 begins with a call to Israel to return to the Lord; the prophet speaks of healing their apostasy and loving them freely. Ezekiel 33:10–20 returns to the problem of guilt, repentance, and life. Psalm 51 brings confession, contrition, and sacrifice into a difficult relationship, insisting upon a broken spirit while later speaking of acceptable sacrifices. The Hebrew scriptures contain more than one model of how purification and mercy work.

Luke's parable is therefore evidence for a recognizable Jewish theology of return. It cannot be made into a recorded transcript of Jesus's exact words without a further historical inquiry. Its moral argument is present in the surviving Gospel and deserves evaluation on its own terms.

The same chapter contains the lost sheep and lost coin. Heaven's joy over the one who repents provides the interpretive frame. The return of the lost is the event the narrative wants the hearer to understand.

The tax collector in the Temple

Luke 18:9–14 gives us a shorter treatment. A Pharisee describes his fasting and tithing. A tax collector stands at a distance and asks God for mercy, acknowledging that he is a sinner. Jesus says the latter goes down to his house justified.

The scene places the appeal for forgiveness inside the Temple and in direct address to God. The man asks for mercy. Jesus announces the outcome. The contrast concerns the moral posture of the worshipper, particularly the danger of self-exaltation and contempt for others.

The tax collector's confession and Zacchaeus's restitution supply complementary descriptions of return. One places the sinner's need before God; the other shows how the sinner's wealth can be returned to the community he has injured. Together, they offer a fuller account than an abstract declaration that one has been justified.

Luke does not abolish the Temple by setting these scenes there. His Gospel opens with priestly service, concludes with disciples worshipping in the Temple, and continues through Acts with followers of Jesus attending its precincts. A reconstruction of Luke as a simple opponent of all sacrificial Judaism would miss that literary setting. His account nevertheless allows forgiveness to appear through repentance, prayer, and restored conduct before any explanation of penal substitution.

Mark's ransom and Luke's serving Messiah

Bart Ehrman has made the central literary comparison with useful force. In his 2017 discussion of Luke's theology and in a February 2026 episode of Misquoting Jesus, he argues that Luke deliberately reshapes Mark's account of Jesus's death. For Ehrman, Mark presents the death as a ransom, whereas Luke understands the unjust execution as an event that exposes the people's wrongdoing and prompts repentance.1

The comparison begins in Mark 10:42–45. Jesus instructs his disciples to abandon the ambition of rulers who dominate others. He says the Son of Man came to serve and to give his life as a ransom for many. The Greek term lytron supplies an explicit redemptive image.

Luke 22:24–27 preserves the dispute about greatness and the call to service in its own setting. Jesus presents himself as the one who serves. The ransom declaration does not appear. This is an observable difference in the extant narratives, consistent with Luke's use of Mark and with the editorial choices that the historian must explain.

The omission is important. It cannot carry the entire case for Luke's theology. An author may omit a saying for reasons of narrative selection while retaining its substance elsewhere. We must therefore inspect the Passion, the resurrection speeches, and the passages that do speak of Jesus's blood.

It also matters what Mark means by ransom. A ransom saying by itself does not set out the later account of God transferring the judicial punishment owed by sinners onto an innocent substitute. John Van Maaren's 2025 study reads Mark's ransom in the setting of Israel's restoration and the Gospel's first-century Judaism. That proposal makes a Jewish redemptive interpretation available within Mark itself. We can distinguish ransom, sacrificial participation, moral example, and penal substitution before claiming that one author adopted or rejected them all together.2

The relation between Mark and Paul must be submitted to the same restraint. Paul writes explicitly of Christ dying for sins in 1 Corinthians 15:3 and develops an argument about redemption in Romans 3. Mark's ransom and covenant-blood language resemble important Pauline claims, but the Gospel does not identify its author as Paul's scribe. John Van Maaren's 2024 evaluation disputes the inference that Mark was distinctly Pauline on the available evidence.2

My own earlier preference for Mark as the most promising Gospel was based partly on its relative chronological priority. That criterion helps reconstruct transmission. It supplies no blanket warrant that every Markan theological elaboration must be more original than every expression preserved in Luke. A later author can retain an early saying while giving it a new literary setting. Passage-level attribution remains the discipline this book has undertaken.

An execution that turns the crowd toward repentance

Luke's crucifixion scene gives Ehrman's comparison its force. Mark 15:34 presents the dying Jesus crying out in apparent abandonment. Luke 23:46 gives him words of trust as he entrusts his spirit to the Father.

Mark narrates the Temple curtain tearing after Jesus dies. In Luke, the tearing is mentioned before the final cry. Mark's centurion calls Jesus Son of God. Luke's centurion calls him dikaios, righteous or innocent. Then the crowds who have seen the events return beating their breasts (Luke 23:47–48).

The breast-beating is not an empty detail. Luke has already described the tax collector beating his breast while calling on God for mercy (18:13). The Passion supplies another image of people who have witnessed wrongdoing and are moved toward grief. Luke's narrator has arranged the execution so that Jesus's righteousness and the onlookers' response occupy the foreground.

The prayer in Luke 23:34, asking the Father to forgive those responsible because they do not know what they are doing, fits this account closely. Its textual history is contested. Some early witnesses, including P75, lack the prayer. Ehrman has argued that it belonged to Luke and was omitted under later anti-Jewish pressure; Whitlark and Parsons have argued that it was inserted as Gospel traditions were harmonized around seven sayings from the cross.3 The manuscript does not get to settle this dispute by choosing the reading that best suits our theology.

Even if the prayer is omitted from the earliest recoverable Luke, Acts 7:60 gives Stephen a similar plea on behalf of his killers. Luke has made the suffering of the righteous and their mercy toward persecutors part of the continuing history of the movement.

The criminal beside Jesus presents another difficulty for a mechanical theory of penance. He acknowledges the justice of his own sentence and Jesus's innocence, asks to be remembered, and is promised Paradise (Luke 23:39–43). The narrative does not describe an opportunity to make economic restitution. Forgiveness remains a gift. Its human response is confession, recognition, and trust.

This gives us an account of martyrdom. Jesus suffers unjust execution, retains his fidelity to God, and becomes a model of trust and mercy for those who will suffer after him. Acts repeats the narrative pattern in Stephen's death. Calling the crucifixion exemplary captures a real Lukan emphasis, while the full theological explanation of the event still has to face Luke's sacrificial passages.

The difficult cup: Luke 22:19–20

The strongest textual challenge to Ehrman's reading comes at the Last Supper.

In the familiar longer form of Luke 22:19–20, Jesus identifies the bread with his body given for his followers and the cup with a new covenant in his blood, poured out for them. The wording carries an obvious sacrificial or covenantal resonance. Luke's theology cannot be reconstructed as though the passage were absent from every witness.

Codex Bezae and certain Western witnesses preserve a shorter form omitting the latter part of verse 19 and verse 20. Many early and important manuscripts, including P75, support the longer wording. The problem involves more than two uniform textual families, because early versional witnesses preserve several arrangements and expansions.

Ehrman defends the shorter form as original, regarding the longer wording as a scribal introduction of a more sacrificial theology. This is a text-critical argument with a history, not an established discovery of Luke's lost autograph. Rob James's 2024 study of the Greek and Syriac variants reaches the opposite conclusion. His analysis argues that the longer version is closer to the original and that the shorter versions share a more complex transmission relationship than the conventional labels suggest.4

The chapter must be readable whichever text-critical conclusion is eventually established.

If the shorter form is original, Luke's editing of Mark supplies additional evidence for an account of the cross built around repentance, vindication, and the resurrection. If the longer form is original, Luke combines his extensive repentance theology with a covenantal declaration concerning the death of Jesus.

Neither result, by itself, establishes the full later doctrine of penal substitution. A covenant ratified in blood and a theory of transferred criminal punishment are distinguishable ideas. The historian needs to determine what work the blood performs in the passage and how the author develops that claim elsewhere.

One more verse complicates the picture: Luke 22:37 cites Isaiah 53:12, concerning the servant numbered with transgressors. That gives Luke an identifiable relationship with Isaiah's suffering-servant tradition. The broader passage in Isaiah 53 has been read sacrificially, and Acts 8:32–35 later applies a passage about the suffering servant to Jesus. Holly Beers documents how Luke's use of Isaiah also makes the servant a model for disciples.5

A reading of Luke's cross that erases these scriptural associations would lose evidence. The aim is to determine whether Luke locates the saving action principally in a penal transaction, in the vindication and exaltation of the righteous servant, or in a broader history of liberation and restored relationship with God.

Acts: what Peter and Paul actually preach

The answer begins to emerge in the speeches of Acts.

At Pentecost, Peter announces Jesus's death, God's raising of him, and his exaltation. The hearers ask what they should do. Peter instructs them to repent and be baptized for forgiveness (Acts 2:22–38).

In Acts 3:13–19, Peter accuses his hearers of rejecting the holy and righteous servant, acknowledges their ignorance, announces that God has fulfilled what was foretold, and calls them to repent and turn back so that their sins may be wiped away. The words express a recognizable connection between the unjust suffering of Jesus and the hearers' conversion. They do not describe a payment of divine punishment transferred to him.

Acts 5:30–31 again associates the killing of Jesus, God's resurrection and exaltation of him, and the granting of repentance and forgiveness to Israel. The saving gift comes through the Messiah whom God has vindicated.

Acts 10:43 announces forgiveness in his name to everyone who believes. Acts 13:38–39 places the proclamation of forgiveness on the lips of Paul himself. Acts 26:20 attributes to Paul's mission the demand for repentance, turning to God, and deeds appropriate to repentance.

This is an exceptionally important fact for the book's argument. The writer of Acts makes Paul preach a message recognizably close to the program of the Baptist and of Luke's Jesus. Its announced response is an altered life under the authority of the risen Messiah.

We should not treat a speech attributed to Paul in Acts as an independent transcript of the historical Paul's words. It is Luke's representation of Paul, and it tells us how this author wished his audience to understand the apostle's mission.

Paul's own letters provide another witness. Romans 3:21–26, Galatians 2, and 1 Corinthians 15 place substantial weight upon the death of Christ and its saving significance. Paul also teaches divine judgment according to conduct (Romans 2:6–11) and speaks of God's kindness leading people to repentance (Romans 2:4). The difference is therefore a matter of emphasis and mechanism, rather than a universe in which Paul has no interest in moral repair.

Acts gives us the evangelist's theology in the mouths of the movement's great missionaries. That gives his distinct message a history without requiring us to identify him as Paul's personal stenographer.

The blood in Acts 20:28

Acts 20:28 makes a stronger challenge. In Paul's farewell to the Ephesian elders, he tells them to shepherd the community that God or the Lord acquired through blood. The exact form is textually debated, including whether the phrase means God's own blood or the blood of his own, understood as his Son. Both textual and translation decisions affect the Christological force of the sentence.6

Its language places the community's acquisition in relation to blood. That is a redemptive claim inside Luke–Acts and it deserves to stand in the account.

David M. Moffitt's 2016 article offers a substantial interpretation of the larger pattern. Moffitt argues that Luke treats Jesus's exaltation as part of a sacrificial movement into God's presence. On his account, Jewish sacrifice comprises a ritual process whose significance extends beyond the killing of a victim. Acts associates forgiveness and purification with Jesus's exaltation because the risen Messiah completes his priestly work before God.7

Moffitt therefore explains much of the material Ehrman emphasizes while retaining sacrificial atonement. His proposal is an important test of any argument that Luke dispenses with every sacrificial category.

I am most concerned with the narrower conclusion. The surviving text gives us a Gospel in which the Messiah repeatedly teaches return, repair, and mercy; Acts proclaims forgiveness through repentance and the risen Messiah. Whether its author also understood Jesus's death and exaltation as a sacrificial event, these themes remain constitutive of his religious message.

The historical question of penal substitution is more specific still. Luke's story never supplies a systematic explanation that the Father imposed the sinner's deserved judicial penalty upon Jesus and thereby enabled forgiveness. Later theologians may construct such an account from the wider canon. The construction must be identified as theological synthesis rather than an unmediated quotation of Luke's own explanatory language.

The author who defended Paul

Luke's relationship to Paul has sometimes been settled through a familiar story: the author was Luke the physician, Paul's traveling companion, and therefore a reliable interpreter of Paul's doctrine. The texts themselves give a less direct route to that conclusion.

The Gospel and Acts are anonymous. Their shared addressee and the opening of Acts identify a literary relationship, and they are usually attributed to one author. The name Luke comes from early Christian attribution. Colossians 4:14 mentions a physician named Luke, while Philemon 24 mentions Luke among Paul's fellow workers; the disputed authorship of Colossians and the absence of a demonstrated authorial link to the Gospel matter to the historical argument.

The first-person plural passages in Acts describe some journeys as 'we' travel. They have been used to defend eyewitness authorship. Other explanations appeal to incorporated travel sources or narrative convention. Sean A. Adams has reviewed the hypotheses and their limitations; modern scholarship includes defenders and critics of the companion identification.8

Bart Ehrman argues that the narrative of Paul's journeys and disputes in Acts differs too substantially from Paul's autobiographical account to assume the author was his intimate associate. Galatians 1–2 and Acts 9, 15 and 21 provide the major comparison points. Ehrman's inference about authorship follows from his assessment of those discrepancies.9

Our manuscript already examines Acts 15 and Galatians 2 in Chapter 25. Acts gives James a public judgment concerning Gentile obligations and subsequently vindicates Paul before accusations that he has rejected Moses. The narrative does literary and apologetic work: it joins Paul to the apostolic movement and presents a shared story of divine guidance.

An author can defend Paul's legitimacy without sharing every element of the theological framework in Paul's letters. That is precisely what the Gospel of Luke and Acts invite us to investigate. The purpose of Acts makes the representation of Paul especially consequential.

The question about Mark demands similar care. His Gospel offers ransom and covenant blood; Paul gives the death of Christ a central saving role. That overlap warrants comparison. It supplies no signed document showing Mark working as Paul's secretary. Van Maaren's alternative reading places Mark's ransom within Israel's restoration. If we are reconstructing the first century, we should begin with what each narrative actually says and trace proposed dependencies from there.

The historical conclusion is a limited one with substantial consequences. Luke–Acts belongs to a tradition of Jesus interpretation that engages Paul's mission while possessing an independent literary and theological profile. The author cannot be reduced to an amanuensis whose every sentence is a paraphrase of Paul's own thought.

Israel's restoration and the Gospel's law

Luke situates repentance inside the story of Israel. The infancy hymns invoke the promises to Abraham and David. Simeon expects consolation, and Anna speaks to those waiting for Jerusalem's redemption. The risen Jesus explains Israel's scriptures to his followers, and Acts presents the announcement as a fulfillment of promises rather than a new deity replacing the God of Israel.

Jason A. Staples has argued that Luke–Acts retains an expectation of Israel's eventual national restoration, a program larger than the salvation of isolated individuals. The prophetic orientation of the Gospel matters because a theology of forgiveness can serve the restoration of a people, their justice, and their worship.10

Luke 10:25–37 places the question of inheriting eternal life beside the commandments to love God and neighbor. The parable of the Samaritan makes neighborliness recognizable in acts of rescue. At Luke 11:42 Jesus criticizes religious precision that neglects justice and the love of God. The Gospel's controversy over religious law frequently concerns the moral purpose of an obligation.

This is where the argument reconnects with James and the Christian-sharia chapters. The Messiah's religion cannot be reconstructed solely as a list of metaphysical beliefs. His followers receive obligations concerning money, strangers, prayer, justice, mercy, and the misuse of authority. The early church's disagreements about circumcision and fellowship require source criticism, while Luke's Gospel has already given a substantive program of righteous life.

The Qurʾān calls the People of the Injīl to judge by what God revealed within it (5:47) and associates the distinct communities with law and a way (5:48). If the Injīl is the guidance given to Jesus, Luke's preserved teachings about return and mercy belong among the candidate materials for our reconstruction. Their exact historical attribution remains the object of the FI saying dossiers. Their content has a direct bearing on the life of anyone claiming to follow the Messiah.

There is an unavoidable test in the language of Luke's wealthy people. Does a confession about salvation alter what the believer does with the food he possesses while a hungry neighbor waits? Luke treats that question as religiously decisive. The Qurʾān's injunctions concerning feeding the poor and honest conduct make the comparison more than a shared moral slogan.

The Gospel that becomes a life

The earlier chapter on Ibn Masʿūd proposed that Jesus can be understood as the Injīl made flesh: a life through which God's revelation becomes visible. The analogy with ʿĀʾisha's report that Muḥammad's character was the Qurʾān, and the report joining ʿAlī with the Qurʾān, turns our attention toward lived fidelity and the guardianship of revelation.

Luke gives that proposal an ethical content. The word carried by Jesus reaches the poor through food, the defrauded through restitution, the estranged through reconciliation, and the guilty through the possibility of return. It reaches the powerful as a demand that their authority cease to crush those entrusted to them.

This is a Gospel for people who have done harm. The prodigal returns home. The tax collector seeks mercy. Zacchaeus opens his ledger. At the execution of the innocent Messiah, witnesses confront their own complicity. After the resurrection, the instruction goes out that repentance and forgiveness are to be proclaimed to the nations in his name (Luke 24:46–47).

That final commission makes the relationship between the Messiah's suffering and the repentance of the world explicit. Christians can legitimately disagree about the sacrificial implications of Luke's narrative. Our source audit has identified the verses that bear on that disagreement, especially 22:19–20 and Acts 20:28. Whatever resolution emerges from the textual history, the Gospel's command to turn and repair remains intact.

The alleged Islamic dilemma is therefore badly posed when it treats the confirmation of the Injīl as confirmation of every later Christian proposition about the Messiah. It gives the text of the councils the position of revelation and then asks the Qurʾān to ratify it. Our inquiry begins with the revelation and teaching attributed to Jesus, grades the witnesses, and follows what they ask of human beings.

Luke's Gospel has given us a demanding candidate for that work. God calls people back. Forgiveness is announced, injustice is named, and the sinner is expected to change his life. Atonement theories can be examined against that proclamation; they cannot take its place.

The Messiah's good news is recognizable when the wrongdoer turns toward God and the person he has harmed finds justice.
