The Bishop of Alexandria was first known as the Bishop of Alexandria. Later, due to the importance and dignity of Alexandria as a major Christian center and as an Ancient Apostolic Throne, and in addition to the fact that the Bishop of Alexandria is the successor of the first Bishop on the Throne of Alexandria, he was given the title of archbishop by the late 3rd century. He was already called by the Alexandrine clergy and by all the Egyptian bishops "papas," since the middle of the 3rd century.
