Antiquities 18.3.3 contains a paragraph about Jesus that, in its surviving form, includes statements that read like Christian confession. Eusebius is the earliest extant writer to quote the passage in this form.
The mythicist reading
This site treats the whole paragraph as a Christian interpolation, not an authentic Josephan core. Eusebius is the earliest extant writer to quote it in this form; the late attestation supports scrutiny of its transmission, though silence by earlier writers is not proof by itself.
The strongest reply
Many scholars think the received passage was altered but preserve a shorter, more neutral original reference. Earlier writers’ failure to quote a passage does not establish that it was absent from their copies. Josephus’ separate reference to James in Antiquities 20.9.1 is a different passage and is treated as substantially authentic by many scholars.
Where the evidence leaves us
This site’s position is that the Testimonium is a Christian interpolation. The strongest counterargument proposes an authentic neutral core, so the wording and transmission history remain central to the debate.
