  Tertullian (c. 155 – c. 220 AD) wrote in his work " The Prescription Against Heretics " about the authority of the church in Rome. In this work, Tertullian said that the Church in Rome has the authority of the Apostles because of its apostolic foundation.
  
  Since, moreover, you are close upon Italy, you have Rome, from which there comes even into our own hands the very authority (of apostles themselves). How happy is its church, on which apostles poured forth all their doctrine along with their blood! Where Peter endures a passion like his Lord's! Where Paul wins his crown in a death like John's where the Apostle John was first plunged, unhurt, into boiling oil, and thence remitted to his island-exile!

In the book, Optatus wrote about the position of the bishop of Rome in maintaining the unity of the Church.
  
  You cannot deny that you are aware that in the city of Rome the episcopal chair was given first to Peter; the chair in which Peter sat, the same who was head—that is why he is also called Cephas —of all the apostles; the one chair in which unity is maintained by all.
