c. 88 The reign of Pope St. Clement I (-97). During his pontificate, he issues a letter to the Corinthians, urging them to submit themselves to lawful religious authority. He writes "Our apostles also knew, through our Lord Jesus Christ, and there would be strife on account of the office of the episcopate. For this reason, therefore, inasmuch as they had obtained a perfect fore-knowledge of this, they appointed those [ministers] already mentioned, and afterwards gave instructions, that when these should fall asleep, other approved men should succeed them in their ministry."90s95 Persecution of Christians in Rome under Domitian.

c. 105 Death of Pope St. Evaristus. Pope St. Alexander I replaces him (-115). c.107-117 Martyrdom of St. Ignatius of Antioch, apostolic Father and bishop. He was a disciple of St. John, along with St. Polycarp. Theodoret, the Church historian says he was consecrated bishop by St. Peter, who was at first bishop of Antioch before going to Rome. Ignatius was martyred in Rome under Emperor Trajan’s rule. It was during the journey to Rome that he wrote his famous letters that contain invaluble information about the early Church. He was the first to use the term “Catholic” to describe the Church.
**110s111* Pliny the Younger, govenor of Bithynia, writes in a letter to the Emperor Trajan that to his surprise, the Christians are not guilty of any of the vices they are rumoured to engage in. He executes Christians who would not apostatize.

160sc. 160 Birth of Tertullian, Church Father. Tertullian apostatized to the Montanist sect and in his later years rejected the Catholic Church. However, in his earlier years, c. 200 AD, he justified Catholic belief against heretics by appealing to the apostolic origin of the Church, whereas the heretics and their heresies were subsequent to it.
*165 Death of St. Justin Martry (b. 100), Church Father. *166 St. Soter becomes Pope. (-175).
There were only seven sees that split off - the rest of them still continue to remain with Rome. Rome is not just sitting there on an island all by itself. There are hundreds and hundreds of Dioceses (sees) that are in full communion with Rome, and always have been.
