External witness

Who Celsus was

The author of The True Word (Alēthēs Logos), the first comprehensive intellectual attack on Christianity — a Middle Platonist’s indictment of the faith as an irrational, subversive novelty fit only for the credulous: he mocked the virgin birth, ridiculed a God who would stoop to incarnation, accused Christians of sedition for shunning civic religion, and yet took their arguments seriously enough to answer them. Nothing of the man is known, not even securely his date; the work itself survives only because, some seventy years later, Origen quoted it almost entire in order to demolish it, so that Celsus speaks to us today only through the mouth of his greatest opponent. Included here as the church’s most formidable named external critic of the second century.

Verified single attestation

Origen alone preserves The True Word; Lucian's addressee of the same name is a debated identification.

Against Celsus I.28 (Origen quoting The True Word)

c. AD 240

Celsus… represents the Jew as disputing with Jesus, and refuting him, as he thinks, on many points: and first, as having fabricated the story of his birth from a virgin.
