As for the dates of the bishops in Jerusalem, I have nowhere found them preserved in writing; for tradition holds that they were exceedingly short-lived.
But this much I have gathered from documents: that down to the siege of the Jews under Hadrian there had been fifteen successions of bishops there. All of these, they say, were Hebrews by origin who had genuinely received the knowledge of Christ from the first, so that they were judged worthy of the bishops’ ministry by those competent to decide such matters. For their whole church at that time consisted of faithful Hebrews who had continued from the apostles down to the siege of that time, in which the Jews, having again revolted from the Romans, were defeated in no small wars.
Since, then, the bishops of the circumcision ceased at that time, it would now be necessary to list them from the first. The first, accordingly, was James who is called the Lord’s brother; after him Simeon was the second, Justus the third, Zacchaeus the fourth, the fifth Tobias, the sixth Benjamin, John the seventh, the eighth Matthias, the ninth Philip, the tenth Seneca, the eleventh Justus, Levi the twelfth, Ephres the thirteenth, the fourteenth Joseph, and last of all, the fifteenth, Judas.
So many were the bishops of the city of Jerusalem who succeeded one another from the apostles down to the time mentioned, all of them of the circumcision.
Now when the reign of Hadrian was already in its twelfth year, Telesphorus, the seventh from the apostles, succeeded Xystus, who had completed ten years in the bishopric of the Romans; and after the interval of a year and some months, Eumenes succeeded to the presidency of the diocese of the Alexandrians as the sixth in the succession, his predecessor having continued for eleven years.
