Something wrong with the graph.
Deceptive to clearly favour Orthodox. The first part of the big red arrow should be "Universal true church" Catholic means universal.
"Around the year A.D. 107, a bishop, St. Ignatius of Antioch in the Near East, was arrested, brought to Rome by armed guards and eventually martyred there in the arena. In a farewell letter which this early bishop and martyr wrote to his fellow Christians in Smyrna (today Izmir in modern Turkey), he made the first written mention in history of "the Catholic Church." He wrote, "Where the bishop is present, there is the Catholic Church" (To the Smyrnaeans 8:2). Thus, the second century of Christianity had scarcely begun when the name of the Catholic Church was already in use."https://www.ewtn.com/faith/teachings/churb3.htm
"the "Martyrdom of St. Polycarp," bishop of the same Church of Smyrna to which St. Ignatius of Antioch had written. St. Polycarp was martyred around 155, and the account of his sufferings dates back to that time. The narrator informs us that in his final prayers before giving up his life for Christ, St. Polycarp "remembered all who had met with him at any time, both small and great, both those with and those without renown, and the whole Catholic Church throughout the world."
We know that St. Polycarp, at the time of his death in 155, had been a Christian for 86 years. He could not, therefore, have been born much later than 69 or 70. Yet it appears to have been a normal part of the vocabulary of a man of this era to be able to speak of "the whole Catholic Church throughout the world."
