We conclude that we find three levels of source material:
- Highly reliable sources. There are two of these: Tacitus and Josephus.
- Moderately reliable sources. We find three: Thallus, Pliny, and Lucian. For the matter of Thallus, please see also our link in our essay to Glenn Miller's essay on that subject, linked in our essay. (We will look at some objections to the Thallus cite.)
- Marginally reliable or unreliable sources. Three are in this class: Suetonius, the letter of Mara Bar-Serapion, and the Talmud.
Another early source mentioned by Justin Martyr (147 A.D.) was a document apparenty extant in his day called the "Acts of Pontius Pilate" as a historical reference for the fact of the crucifixion of Jesus Christ by Pontius Pilate. Such a document would have been written near the time of the crucifixion event.

Chapter XXXV.-Other Fulfilled Prophecies.
And the expression, "They pierced my hands and my feet," was used in reference to the nails of the cross which were fixed in His hands and feet. And after He was crucified they cast lots upon His vesture, and they that crucified Him parted it among them. And that these things did happen, you can ascertain from the Acts of Pontius Pilate. 71

These Acts of Pontius Pilate, or regular accounts of his procedure sent by Pilate to the Emporer Tiberius, are supposed to have been destroyed at an early period, possibly in consequence of the unanswerable appeals which the Christians constantly made to them. There exists a forgery in imitation of these Acts. See Trollope.
