Although open to historical debate, first-century Christian communities may have had a group of presbyter-bishops functioning as guides of their local churches. Gradually, episcopal sees were established in metropolitan areas. Antioch may have developed such a structure before Rome. In Rome, there were over time at various junctures rival claimants to be the rightful bishop, though again Irenaeus stressed the validity of one line of bishops from the time of St. Peter up to his contemporary Pope Victor I and listed them. Some writers claim that the emergence of a single bishop in Rome probably did not occur until the middle of the 2nd century. In their view, Linus, Cletus and Clement were possibly prominent presbyter-bishops, but not necessarily monarchical bishops. Documents of the 1st century and early second century indicate that the bishop of Rome had some kind of pre-eminence and prominence in the Church as a whole, as even a letter from the bishop, or patriarch, of Antioch acknowledged the bishop of Rome as "a first among equals",The Early Christian Church by Chadwick though the detail of what this meant is unclear.
