Peer reviewed monograph applying Bayesian method to the historicity of Jesus
On the Historicity of Jesus: Why We Might Have Reason for Doubt is a peer-reviewed academic study by American historian Richard Carrier that tests the probability that Jesus of Nazareth existed as a historical person using Bayesian reasoning across background knowledge and surviving evidence. First issued by Sheffield Phoenix Press in June 2014 and revised in 2023, the book compares a minimal-historicity model to a minimal-mythicism model and argues that the latter explains the evidence at least as well as the former.[1]
Background and development
[edit]
Carrier positioned the volume as the application of the probabilistic method he defended in Proving History. He announced prior to publication that the manuscript “passed peer review” and was accepted by Sheffield-Phoenix, stating that the project would present a testable comparison between historicist and mythicist explanations of Christian origins. The book received approval from “two peer review reports from major professors” which Carrier noted was “the standard number for academic publications.” He highlighted its significance as “the first comprehensive pro-Jesus myth book” to be “published by a respected academic press and under formal peer review.”[2]
Methodology and hypotheses
[edit]
Carrier defines two competing hypotheses, estimates priors from background knowledge about ancient religion and historiography, then updates with likelihoods derived from the surviving record. The study inventories features of Greco Roman religious movements, Jewish apocalyptic expectations, scriptural interpretation practices, and information spread in urban networks, and evaluates how these variables affect the probability of each hypothesis.[1]
Carrier surveys Greco Roman hero cults, Jewish wisdom and martyr traditions, diaspora synagogue networks, and the mechanics of textual production and oral performance. He argues that Pauline letters center on a revealed Christ, that earliest language about Jesus aligns with celestial conceptions, and that the Gospels function as literary constructions that embed scriptural allusion and midrash to craft recent biography, which can be expected if a mythic origin was later placed in history.[1]
The book operationalizes Bayes theorem for historical inference by separating background frequencies from evidence specific likelihoods, then by computing which model receives the greater posterior support. The framework emphasizes reference class reasoning, prior sensitivity analysis, and comparative prediction of what kinds of sources should survive if each hypothesis were true.[1]
| Hypothesis | Summary | Evidence features expected |
|---|---|---|
| Minimal historicity | A historical Jewish teacher named Jesus existed in the early first century, attracted followers, was executed by Roman authority, and became the focal cause of the movement | Independent attestation to a human teacher, coherent memory trajectories from disciples to texts, fit with Second Temple socio politics, plausible origins for titles and cult claims under a human founder model[1] |
| Minimal mythicism | The earliest sect revered a celestial Jesus known through revelation and scripture, then later narratives Euhemerized that figure into recent history as biography and cult myth converged | Scarcity of early biographical detail, prominence of visionary and scriptural sources in earliest texts, patterns analogous to other salvific cults, later redactional development toward historicized stories[1] |
Contemporary academic reception has been mixed. Raphael Lataster reviewed the book in the Journal of Religious History, outlining Carrier’s model comparison and situating it within debates over Jesus’ historicity.[3]
Christina Petterson reviewed the volume in Relegere: Studies in Religion and Reception. She challenged the use of Bayesian devices and judged the book’s New Testament discussions to be basic, writing that “even if strictly correct, the methodology is tenuous. The numbers and the statistics seem like a diversion.”[4]
Daniel N. Gullotta published a 37-page response essay in the Journal for the Study of the Historical Jesus. He summarized Carrier’s thesis and concluded that “Carrier’s hypothesis is problematic and unpersuasive,” while critiquing specific probability assignments and readings of early sources.[5] In 2021, the journal subsequently openly published his response for non-academics to read.[6]
Methodological discussion also appeared, positively noting the method, but criticizing priors. Aviezer Tucker, a philosopher of history supportive of Bayesian historiography, reviewed Carrier’s Bayesian program and related claims in History and Theory, commending probabilistic reasoning in principle but disputing aspects of Carrier’s application.[7] In 2025, Gregor et al. found that using more recent historical figures (post-10th century BC) rather than ancient ones dramatically increased the calculated probability of Jesus’ historicity from 33% to 99%.[8]
Subsequent research articles also addressed core premises of mythicist reconstructions. Simon Gathercole argued in the Journal for the Study of the Historical Jesus that the undisputed Pauline letters presuppose a historical and human Jesus, positioning this as a counter to mythicist claims.[9]
