To verify the authenticity of the Gospel of Judas documents,
the National Geographic Society scrutinized them
as closely as was possible without harming them further.
The University of Arizona's radiocarbon dating lab—the same lab that dated the Dead Sea Scrolls—subjected the Gospel of Judas papyruses to a thorough test.
Leading scholars compared the Gospel's theological concepts and linguistic style with those of authentic Egyptian documents from the same era.
Handwriting experts examined the text's distinctive script and compared it to those found in other ancient works—such as the Nag 'Hammadi codices.
