Moreover, if there be any [heresies] bold enough to plant themselves in the midst of the apostolic age, so that they might seem to have been handed down by the Apostles because they were from the time of the Apostles, we can say to them: let them show the origin of their Churches, let them unroll the order of their bishops, running down in succession from the beginning, so that their first bishop shall have for author and predecessor some one of the Apostles or of the apostolic men who continued steadfast with the Apostles. For this is the way in which the apostolic Churches transmit their lists: like the Church of the Smyrnaeans, which records that Polycarp was placed there by John; like the Church of the Romans where Clement was ordained by Peter. In just this same way the other Churches display those whom they have as sprouts from the apostolic seed, having been established in the episcopate by the Apostles. Let the heretics invent something like it. After their blasphemies, what could be unlawful for them? But even if they should contrive it, they will accomplish nothing; for their doctrine itself, when compared with that of the Apostles, will show by its own diversity and contrariety that it has for its author neither an Apostle nor an apostolic man. The Apostles would not have differed among themselves in teaching, nor would an apostolic man have taught contrary to the Apostles, unless those who were taught by the Apostles then preached otherwise.
