External witness

Who Elchasai (Elxai) was

The shadowy 'hidden power' behind the Book of Elchasai — a revelation said to have been delivered under Trajan by an angel ninety-six miles high, teaching a second baptism for the remission of even the gravest sins. Whether prophet or literary fiction, the book was real: Alcibiades carried it to Rome a century later, and Hippolytus dissected it with relish.

Also listed in non-christian witnesses.
