"Paul's conversion proves the resurrection"

The apostle Paul's transformation from persecutor of Christians to Christianity's most influential missionary is frequently presented as evidence for the resurrection of Jesus. The argument, advanced by apologists such as Gary Habermas, William Lane Craig, and Michael Licona, contends that Paul's sudden and dramatic change can only be explained by a genuine encounter with the risen Christ.^{1, 2} As Craig has argued, Paul's conversion is "one of the best-attested facts about Jesus" and provides "independent confirmation" of the resurrection.² Yet this argument conflates subjective experience with objective verification, ignores the problematic nature of our sources, and fails to account for the well-documented phenomenon of dramatic religious conversion across all faith traditions.

The apologetic argument

The argument from Paul's conversion typically proceeds as follows. Paul (originally named Saul) was a zealous Pharisee who actively persecuted the early Christian movement.³ By his own account, he was "violently persecuting the church of God and was trying to destroy it" and was "advancing in Judaism beyond many among my people of the same age" in his zeal for ancestral traditions.⁴ Something then happened that transformed this persecutor into Christianity's most prolific apostle, the author of at least seven New Testament letters who traveled thousands of miles establishing churches across the Mediterranean world.³

Apologists argue that this transformation is best explained by a genuine encounter with the risen Jesus. Gary Habermas and Michael Licona, in their influential book The Case for the Resurrection of Jesus, list Paul's conversion among their "minimal facts" that even skeptical scholars allegedly accept.¹ They contend that Paul had no natural motivation to convert, that his conversion came at great personal cost, and that the only adequate explanation for such a radical change is that he genuinely experienced the risen Christ.¹

William Lane Craig frames the argument in similar terms. In Reasonable Faith, he argues that "the origin of the disciples' belief in the resurrection is best explained by the historical resurrection of Jesus."² Paul's conversion features prominently in this argument because, unlike the original disciples who might have had psychological motivation to believe their teacher had risen, Paul was an enemy of the movement with every reason to reject such claims.² The dramatic nature of his reversal, apologists contend, requires an explanation beyond natural psychological processes.

What Paul actually says

The most reliable evidence for Paul's conversion experience comes from his own letters, which are our earliest Christian documents. In these letters, Paul describes his experience in notably vague and visionary terms, quite different from the dramatic narrative familiar from Acts.⁵

In Galatians 1:15-16, Paul writes that God "was pleased to reveal his Son to me" (Greek: apokalypsai ton huion autou en emoi). The Greek phrase en emoi can be translated either "to me" or "in me," with many scholars preferring the latter reading, which would indicate an internal, mystical experience rather than an external appearance.^{5, 6} Paul uses the language of "revelation" (apokalypsis), the same terminology he employs elsewhere for visionary experiences and mystical knowledge.⁶

In 1 Corinthians 15:8, Paul states that the risen Christ "appeared also to me" (ophthe kamoi). Significantly, Paul uses the same verb (ophthe) to describe both the appearances to the original disciples and his own experience, placing them in the same category.⁷ Yet Paul's experience came years after Jesus's death, when there was obviously no physical body to see. This suggests that Paul understood all post-resurrection "appearances," including those to Peter and the Twelve, as visionary rather than encounters with a physical body.^{7, 8}

In 2 Corinthians 12:1-4, Paul describes being "caught up to the third heaven" and "into Paradise," where he "heard things that are not to be told." He explicitly calls these "visions and revelations of the Lord."⁴ The fact that Paul places his Damascus Road experience in the same category as these clearly mystical, visionary experiences is revealing. As New Testament scholar Paula Fredriksen observes, Paul "never describes actually 'seeing' a body. What he claims is a vision."⁸

Crucially, Paul argues in 1 Corinthians 15:44-50 that the resurrection body is a "spiritual body" (soma pneumatikon), not a physical one (soma psychikon). He states explicitly that "flesh and blood cannot inherit the kingdom of God."⁴ This theological position is difficult to reconcile with the later Gospel narratives where the risen Jesus eats fish, invites Thomas to touch his wounds, and insists he is not a ghost.⁹ Paul's understanding of resurrection appears to have been more akin to a transformation into a heavenly, spiritual existence than resuscitation of a corpse.^{7, 8}

The contradictions in Acts

The detailed narrative of Paul's conversion familiar to most Christians comes not from Paul himself but from the Acts of the Apostles, which contains three separate accounts of the event: Acts 9:1-19, 22:6-16, and 26:12-18. These accounts, all written by the same author (traditionally identified as Luke) decades after the events, contradict each other on significant details.¹⁰

Contradictions between the three Acts accounts of Paul's conversion^{10, 11}

The contradiction regarding whether Paul's companions heard the voice is particularly striking. In Acts 9:7, the Greek text uses the genitive case with akouo, which typically means "to hear" in the full sense. In Acts 22:9, the accusative case is used with the same verb, which some apologists argue means merely "to understand."¹² However, as Bart Ehrman notes, this grammatical distinction is not consistently applied in Koine Greek, and the natural reading of the two passages is that they flatly contradict each other.¹⁰ Even granting the apologetic interpretation, the texts still contradict on whether the companions fell down and on who commissioned Paul.¹⁰

The discrepancy about who gave Paul his mission is theologically significant. In Acts 9 and 22, Ananias tells Paul what his mission will be. In Acts 26, Jesus himself commissions Paul directly on the road, with no mention of Ananias at all.¹¹ These cannot both be accurate descriptions of the same event.

These contradictions are significant for the apologetic argument because they demonstrate that even our most detailed source for Paul's conversion is unreliable on basic factual details. The Acts of the Apostles was written approximately 50-60 years after Paul's conversion, by an author who was not present and whose agenda included presenting a harmonized portrait of early Christianity.¹³ If the author of Acts could not keep straight such simple details as whether Paul's companions heard the voice or fell down, the reliability of the entire narrative is called into question.¹⁰

The psychology of conversion

The argument that Paul's conversion can only be explained supernaturally rests on the assumption that natural psychological processes cannot account for dramatic religious transformations. This assumption is contradicted by extensive research in the psychology of religion.^{14, 15}

William James, in his foundational 1902 work The Varieties of Religious Experience, documented numerous cases of sudden, dramatic religious conversion involving visions, voices, and complete personality transformation.¹⁴ James found that such experiences were often preceded by a period of psychological distress, internal conflict, or what he called the "divided self."¹⁴ The conversion experience resolved this internal tension by unifying the self around a new center of belief. James explicitly noted that the psychological mechanisms were the same regardless of the content of the new beliefs.¹⁴

Modern research has confirmed and extended James's observations. Lewis Rambo's comprehensive study Understanding Religious Conversion identifies multiple factors that contribute to conversion, including personal crisis, social encapsulation (immersion in a new social network), and what he terms "the interaction between cognitive and emotional processes."¹⁵ Rambo emphasizes that conversion is not a single event but a process, and that the dramatic "Damascus Road" type of sudden conversion is actually less common than gradual transformation.¹⁵

Cognitive dissonance theory, developed by Leon Festinger, offers a particularly relevant framework for understanding Paul's conversion.¹⁶ Festinger found that when people hold conflicting beliefs, they experience psychological discomfort that motivates them to reduce the inconsistency. Sometimes this results in changing beliefs in unexpected directions. Paul's active persecution of Christians would have required repeated exposure to their message and their willingness to suffer for it. This exposure may have created cognitive tension that was eventually resolved through conversion.¹⁷

Bereavement visions provide another relevant parallel. Research has documented that a significant percentage of bereaved individuals report sensing the presence of, hearing, or seeing the deceased person. One study found that 39% of widows and widowers reported such experiences.¹⁸ These experiences are not considered pathological and occur in psychologically healthy individuals. If Paul felt guilt about his persecution of Christians, particularly if any had died as a result, such psychological mechanisms could contribute to a visionary experience.¹⁷

Temporal lobe epilepsy (TLE) has also been proposed as a possible factor in Paul's conversion. Individuals with TLE sometimes report intense religious experiences, visions, and hearing voices. Some researchers have suggested that Paul's description of his experience, including the bright light and temporary blindness, could be consistent with a TLE seizure.¹⁹ This hypothesis remains speculative, but it illustrates that there are medically recognized conditions that can produce exactly the kind of experience Paul describes.¹⁹

Parallel conversions in other traditions

If Paul's conversion uniquely requires a supernatural explanation, we would expect such dramatic reversals to be rare or absent in other religious traditions. In fact, history is replete with examples of equally dramatic conversions to beliefs Christians would consider false, undermining the argument that the nature of the conversion proves the truth of the belief.²⁰

Muhammad's initial revelation in the cave of Hira transformed him from an ordinary merchant into the founder of Islam. According to Islamic tradition, Muhammad initially doubted the experience and feared he was possessed, but eventually became convinced he had received a genuine revelation from God through the angel Gabriel.²¹ Over 1.8 billion Muslims today consider this conversion genuine evidence of divine revelation.²² If the logic of the argument from Paul's conversion is valid, it should apply equally to Muhammad, yet Christian apologists would reject this conclusion.

Joseph Smith, founder of the Church of Jesus Christ of Latter-day Saints, reported a vision in 1820 in which God the Father and Jesus Christ appeared to him in a grove of trees.²³ Smith went on to found a religious movement that now has over 16 million members worldwide, and many early followers sacrificed their lives for their beliefs.²⁴ The sincerity of Smith's conviction and his followers' willingness to die for their beliefs parallels the argument made for Paul, yet mainstream Christians reject Mormonism's truth claims.

The Buddha's enlightenment under the Bodhi tree represents another dramatic transformation. According to tradition, Siddhartha Gautama was a wealthy prince who abandoned his family and privilege to seek spiritual truth, eventually achieving enlightenment after intense meditation and inner struggle.²⁵ The Buddhist tradition has produced countless examples of dramatic spiritual transformation over 2,500 years.²⁵

Major world religions founded on dramatic conversion experiences²²

More recent examples abound. Malcolm X's dramatic conversion to the Nation of Islam while in prison transformed him from a criminal into one of the most influential figures of the civil rights era.²⁶ Charles Colson, one of the Watergate conspirators and a man known for his ruthlessness, converted to evangelical Christianity and founded Prison Fellowship Ministries.²⁷ In each case, the sincerity of the conversion is not in doubt, yet the truth of the beliefs acquired varies by the standards of any given observer.

The existence of equally dramatic conversions across mutually exclusive religious traditions demonstrates that the psychological capacity for such experiences is a human universal, not evidence for any particular theology. If a Christian apologist accepts that Muhammad's conversion was sincere but mistaken, they have conceded that sincere conversion experiences can occur without supernatural causation, at which point the same explanation becomes available for Paul.²⁰

The logical gap

Even if we grant that Paul had a powerful subjective experience that he interpreted as an encounter with the risen Christ, this does not establish that Jesus actually rose from the dead. The argument commits a fundamental logical error by conflating the occurrence of an experience with the accuracy of its interpretation.²⁸

The argument can be formalized as follows. Paul had an experience. Paul interpreted this experience as seeing the risen Jesus. Therefore, Jesus rose from the dead. The conclusion does not follow from the premises. The argument requires an additional premise: that Paul's interpretation of his experience was correct. But this is precisely the question at issue, and it cannot be established by appealing to the sincerity or intensity of the experience itself.²⁸

People have sincere, powerful experiences that they interpret as encounters with deceased loved ones, alien abductions, past-life memories, and communications with various deities. The sincerity of these experiences is not generally taken as evidence that the interpretations are accurate.²⁹ Neurological and psychological research has demonstrated that the human brain can generate vivid, convincing experiences that do not correspond to external reality.³⁰

The argument also assumes that we have reliable access to what Paul actually experienced, rather than merely his later interpretation of that experience. Paul's letters were written years or decades after his conversion, and the Acts accounts were written even later by someone else.¹³ Memory research has demonstrated that memories are reconstructed each time they are recalled and are shaped by subsequent beliefs and experiences.³¹ What Paul remembered of his experience may have been significantly influenced by his subsequent theological development.

Furthermore, even Paul's own account reveals uncertainty about the nature of his experience. In 2 Corinthians 12:2-3, when describing his vision of paradise, Paul says "whether in the body or out of the body I do not know, God knows."⁴ If Paul himself was unsure whether his visionary experiences were physical or purely spiritual, it is difficult to use those experiences as evidence for a physical resurrection.⁷

Alternative explanations

Several naturalistic explanations have been proposed for Paul's conversion, none of which require supernatural intervention. While we cannot definitively determine what happened to Paul on the Damascus Road, the existence of plausible alternatives undermines the apologetic claim that supernatural causation is the only adequate explanation.¹⁷

The cognitive dissonance hypothesis suggests that Paul's persecution of Christians forced him into repeated contact with their message and their willingness to suffer for it. This exposure may have created subconscious doubt or attraction that eventually broke through in a dramatic psychological event.¹⁷ The intensity of Paul's persecution could itself be evidence of internal conflict; as the saying attributed to Shakespeare goes, "the lady doth protest too much."¹⁷

Guilt and grief offer another potential explanation. If Paul's persecution contributed to any deaths, such as that of Stephen (whose execution Paul reportedly witnessed and approved), he may have experienced significant psychological distress, even if not consciously acknowledged.¹⁷ Bereavement-type visions and guilt-induced experiences could explain both the apparition and the content of the message Paul believed he received.

The sociological perspective emphasizes that conversion is rarely a purely individual phenomenon. Paul operated within a social context where Christianity was spreading and generating significant attention. His persecution activities would have brought him into contact with Christian communities and their compelling narratives.¹⁵ The social networks he encountered may have played a role in his eventual adoption of Christian beliefs.

Some scholars have suggested that Paul may have been predisposed to mystical experiences. His letters reveal someone who claims multiple visions and revelations, who speaks of being "caught up to the third heaven," and who sees the spiritual realm as intimately connected to daily life.⁶ Such individuals may be more prone to dramatic religious experiences regardless of the specific trigger.

The problem of verification

A fundamental problem with the argument from Paul's conversion is that it relies entirely on the testimony of one interested party. We have no independent verification that Paul's experience occurred as he described it, no neutral observers who can confirm the details, and no way to test his interpretation.²⁸

This stands in sharp contrast to the standards of evidence we apply in other domains. In a court of law, the uncorroborated testimony of a single witness, particularly one who stands to gain from the testimony, is generally insufficient to establish contested facts.³² In science, extraordinary claims require independently replicable evidence.³³ In history, we are appropriately skeptical of ancient claims of miracles and supernatural events, recognizing that such claims were common in the ancient world and that people routinely believed things we now know to be false.³⁴

The claim that Jesus rose from the dead is an extraordinary claim by any standard. It asserts that the normal laws of biology were suspended in one specific case two thousand years ago. The evidence offered is the testimony of people who believed they had visions, filtered through documents written decades after the events by people who were not present.⁹ Even if we accept that Paul sincerely believed he encountered the risen Christ, this is weak evidence for such an extraordinary claim.

Apologists sometimes argue that Paul had "nothing to gain and everything to lose" by his conversion, which shows his testimony is reliable.¹ But this is questionable on multiple grounds. First, converts often find that their new beliefs provide meaning, purpose, and community that compensate for worldly losses.¹⁵ Second, Paul gained significant status in the Christian movement, becoming one of its most influential leaders.³ Third, the argument proves too much: followers of countless religious movements have sacrificed worldly goods and status for their beliefs, yet we do not take this as evidence that those beliefs are true.

The argument from Paul's conversion ultimately asks us to accept that because one man two thousand years ago had a powerful experience and interpreted it as encountering a resurrected person, we should believe that a resurrection actually occurred. This is an extraordinary inferential leap that far exceeds what the evidence can support.²⁸

The scholarly perspective

Mainstream New Testament scholarship takes a more measured view of Paul's conversion than popular apologetics suggests. While scholars across the theological spectrum acknowledge that Paul had some kind of transformative experience, they differ significantly on what can be concluded from it.⁹

E.P. Sanders, one of the most influential New Testament scholars of the twentieth century, argued that we cannot reconstruct what actually happened to Paul. In Paul and Palestinian Judaism, Sanders wrote that "we have no access to what Paul actually saw or experienced; we only have access to his interpretation of it."³⁵ Sanders emphasized that Paul's theology cannot be derived straightforwardly from his conversion experience but represents subsequent reflection and development.³⁵

Paula Fredriksen, a historian of ancient Christianity, has emphasized that Paul's experience should be understood within the context of ancient Jewish apocalypticism. Paul expected the imminent end of the world and the general resurrection of the dead; his vision of Christ fit within this existing framework of expectation.⁸ The content of Paul's experience was shaped by the beliefs he already held about God's coming intervention in history.

Gerd Lüdemann, a German New Testament scholar, has argued that Paul's conversion can be explained as a visionary experience produced by psychological conflict. In The Resurrection of Christ: A Historical Inquiry, Lüdemann proposed that Paul's persecution of Christians created unconscious guilt and attraction that eventually surfaced in a vision.¹⁷ While this hypothesis cannot be proven, it provides a naturalistic explanation that accounts for the data.

Even scholars who personally believe in the resurrection, such as N.T. Wright, acknowledge that Paul's experience was visionary in nature and cannot be used as straightforward historical proof. Wright argues that the resurrection is the best explanation for the rise of Christianity as a whole, not that any single piece of evidence proves it independently.³⁶ This more modest claim is quite different from the apologetic assertion that Paul's conversion "proves" the resurrection.

The scholarly consensus, to the extent one exists, is that Paul had a genuine experience that transformed his life, but that the nature and cause of this experience cannot be determined with historical certainty. The leap from "Paul had an experience" to "Jesus rose from the dead" is not one that most critical scholars are willing to make based on the available evidence.^{9, 37}
