Why does Josephus’ reference to Jesus appear to be a later Christian interpolation?

I. Historical Context of Josephus

Flavius Josephus (ca. AD 37–100) was a first-century Jewish historian known for his detailed writings about Jewish history, especially in his works “The Jewish War” and “Antiquities of the Jews.” His birth and upbringing occurred in a period fraught with Roman occupation, civil unrest, and the eventual destruction of Jerusalem in AD 70. Josephus served as a general in Galilee before ultimately defecting to the Roman side, which gave him unique perspectives on the Jewish-Roman conflicts.

Due to his background and the historical setting in which he wrote, Josephus’s works have long held an important place in the study of the New Testament era and the history of early Judaism and Christianity. One of the passages most scrutinized today is the so-called “Testimonium Flavianum” (Antiquities of the Jews 18.63–64), in which Josephus allegedly refers to Jesus of Nazareth. Some have questioned whether these references are entirely authentic or whether scribes later inserted Christian-oriented statements.

II. The “Testimonium Flavianum” in Antiquities of the Jews

In Antiquities of the Jews 18.63–64, we find the notable passage sometimes attributed to Josephus:

• It references Jesus as a wise teacher.

• It indicates that He performed surprising deeds.

• It notes that He had followers among both Jews and Gentiles.

• It acknowledges the claim of His resurrection.

The traditional Greek text, as preserved in medieval manuscripts, includes phrases such as “if indeed one ought to call Him a man” and states outright that Jesus was “the Christ.” These statements, on the surface, appear uncharacteristically Christian in tone, prompting many scholars to wonder whether Josephus himself would have made such explicit affirmations about Jesus’s identity.

III. Reasons Some Propose a Later Interpolation

1. Overtly Christian Language

The passage’s wording—calling Jesus “the Christ” and describing His resurrection in a straightforward confessional manner—strikes many as departing from Josephus’s usual, more neutral style toward messianic figures. Because Josephus was not a follower of Jesus and tended to avoid theological endorsements, the distinctly Christian phrases raise suspicion.

2. Literary Flow and Stylistic Considerations

Certain phrases in the Testimonium Flavianum differ from Josephus’s typical writing. Scholars often note that removing the more Christian elements causes the surrounding text to read more smoothly in context, suggesting those disputed phrases may have been inserted later.

3. Earliest Manuscript Evidence

The earliest extant Greek manuscripts of Josephus’s works date back to around the 10th or 11th century. Before that, church historian Eusebius (ca. AD 260–339) quotes a similar version of the passage (Ecclesiastical History I.11). Whether Eusebius himself quotes an already interpolated text, or accurately preserves an original form, remains a matter of debate.

4. Lack of References in Origen

Origen (mid-2nd to mid-3rd century) knew Josephus’s writings well and references Josephus’s mention of “James, the brother of Jesus, who was called Christ” (Antiquities of the Jews 20.9.1). However, Origen makes no mention of Josephus’s purported explicit attestation of Jesus’s resurrection from Antiquities 18.63–64. This omission is seen by some as a clue that the unambiguously Christian statements might not have been present in Origen’s copy.

IV. Partial Authenticity Theory

Many scholars propose a “partial authenticity” position, suggesting Josephus did indeed mention Jesus but that certain Christian expressions were inserted by later Christian scribes. Under this theory, Josephus’s genuine core lines could have acknowledged Jesus as a notable teacher who attracted a following and was executed under Pontius Pilate. Over time, scribes, wishing to strengthen Josephus’s testimony, may have embellished certain details (like explicitly calling Jesus the Messiah).

One alternate version, preserved in an Arabic text quoted by the 10th-century historian Agapius, contains a slightly different form of the passage. It reads more like a neutral description rather than a direct confession of Jesus’s messiahship or resurrection, giving some weight to the possibility that the Greek text includes later editorial additions.

V. Reference to Jesus in Antiquities of the Jews 20.9.1

In another portion of Josephus’s work, he references “James, the brother of Jesus, who was called Christ.” This passage is comparatively less disputed. Its simpler reference aligns with Josephus’s typical style: stating that some in the Jewish leadership accused James. The modest tone (“who was called Christ”) lacks any glowing acceptance or theological commentary. This more guarded wording helps confirm that Josephus did indeed acknowledge Jesus’s historical existence and that He was recognized by some as the Christ. Critics note that this kind of neutral mention is more in keeping with Josephus’s style than the possibly embellished statements in the Testimonium Flavianum.

VI. Scholarly Insights and Early Christian Writers

• Eusebius (ca. AD 260–339): In his Ecclesiastical History (I.11), Eusebius quotes the Testimonium Flavianum, showing that at least by the fourth century, a form of the passage was in circulation. Whether that form was already likely subjected to interpolation is debated.

• Origen (ca. AD 184–253): He cites Josephus’s mention of James without referencing the more explicit lines about Jesus’s resurrection in Antiquities 18. This absence bolsters the argument that Origen did not consider Josephus a direct witness to Christian theological claims.

• Modern Analysis: Many textual critics compare the Greek and Arabic versions, weigh the internal literary evidence, and discuss how scribal tendencies in transmitting religious texts can introduce expansions for doctrinal clarity.

VII. Historical Reliability and Archaeological Backdrop

In evaluating the possible interpolation, it is also noteworthy that archaeological discoveries—like the Pilate Stone (found in Caesarea in 1961)—confirm the real historical circumstances of the Roman prefect Pontius Pilate. The existence of these historical figures mentioned by Josephus and the New Testament helps anchor key events in verifiable history.

Beyond Josephus, other ancient writings—such as those by Roman historians Tacitus (Annals 15.44) and Suetonius (Lives of the Caesars, “Nero” 16)—allude to Jesus’s early followers. While these references do not prove or disprove potential interpolations in the Testimonium Flavianum, they collectively show that Jesus and the early Christian movement had become recognized subjects in historical records.

VIII. Relevant Scriptural Perspective

Scripture underscores the importance of verifying claims with more than one source: “Every matter must be established by the testimony of two or three witnesses” (2 Corinthians 13:1). Josephus’s mention of James in Antiquities 20.9.1, references in Tacitus, and the New Testament narratives themselves constitute multiple lines of historical attestation pointing to Jesus’s real presence in first-century Judea.

IX. Encouragement for Further Study

1. Examination of Manuscript Tradition

Researchers can delve deeper into Greek and Latin manuscripts of Josephus, as well as the Arabic versions, to evaluate shifts in wording and context. Institutions and libraries around the world hold manuscript fragments that potentially shed further light on how scribes transmitted Josephus’s text.

2. Comparisons with Church Fathers

Cross-referencing quotes of Josephus in patristic writings (e.g., Jerome, Ambrose) can help trace how early Christians regarded (and occasionally modified) these passages.

3. Consideration of Historical-Cultural Context

Understanding Josephus’s stance as a devout Jew writing to both Jewish and Roman audiences can clarify what he was likely or unlikely to say about a figure revered by a growing Christian movement.

X. Conclusion

Josephus’s references to Jesus provide a significant extra-biblical acknowledgment of the historical figure at the heart of early Christianity. While the passage in Antiquities of the Jews 18.63–64 (the Testimonium Flavianum) includes statements that many consider authentic, it also contains language suggesting later Christian interpolation. Skepticism centers on overtly Christian phrases that conflict with Josephus’s typical, more restrained style.

Nevertheless, the broader consensus recognizes that Josephus did, in some capacity, write of Jesus as a historical person and that later scribes may have enhanced certain doctrinal nuances. The less-disputed reference to Jesus and His brother James in Antiquities 20.9.1 supports the notion that Josephus viewed Jesus as a notable figure of the era.

Modern translations, writings from the early church, manuscript evidence, and archaeological contributions (such as the Pilate Stone) converge to paint a historically credible backdrop and underscore the viability of Josephus’s underlying testimony about Jesus. While the exact wording of the Testimonium Flavianum may not have survived entirely free from scribal edits, the core historical kernel—Josephus’s acknowledgment of Jesus—persists as compelling corroboration alongside the New Testament record.
