The article explores the significance of Egyptian papyri in studying early Christianity and especially the persecution in the Roman Empire in the first centuries. The special attention is paid to the hypothesis of S. Huebner, who has suggested that P. Mil. Vogl. 6.287 (2nd-3rd centuries) is the first known judicial record of the interrogation of Christians, preserved without any alterations and editing. She came to this conclusion on the basis of the accusation of conspiracy (συνωμοσία) and the identification of Soth and Dioscorus, the son of Origen, mentioned in the text, with the Egyptian Christians previously known from other papyri. S. Huebner’s arguments are of some interest, but they seem not to be completely convincing.
