Thus Theodoret of Cyrus, unjustly deposed by Dioscorus of Alexandria in the Latrocinium of Ephesus, flies "to the Apostolic throne" of St. Leo; "for in all things it is becoming that you should have the primacy. For your throne is adorned with many advantages. It has the sepulchres of our common Fathers and teachers of the truth, Peter and Paul. These have made your throne exceedingly illustrious. This is the height of your blessings."[75] Though a supplicant, he addresses him only as first Bishop of the Church, not as monarch. It is a virtual denial of the present Papal authority, because a silence, where it would have been put forward, had it been known. So the heretic Eutyches, before the council of his own Patriarch, "when his deposition was read, appealed to the holy synod of the most holy Bishop of Rome, and Alexandria, and Jerusalem, and Thessalonica."[76] Thus St. Isidore of Spain, in the sixth century, says: "The order of Bishops is fourfold; that is, Patriarchs, Archbishops, Metropolitans, and Bishops. In Greek a Patriarch is called the first of the Fathers, because he holds the first, that is, the Apostolic place, and therefore, because he holds the highest rank, he has such an appellation, as the Roman, the Antiochene, and the Alexandrine."[77] Accordingly Gieseler says, "At the end of this period," (A.D. 451,) the four Patriarchs of the East "were held in their patriarchates for ecclesiastical centres, to which the other Bishops had to attach themselves for maintenance of ecclesiastical unity; and in conjunction with their patriarchal synod they formed the highest tribunal of appeal in all ecclesiastical matters of the patriarchate; whilst, on the other hand, they were treated as the highest representatives of the Church, who, through mutual communication with each other, were to maintain the unity of the universal Church, and without whose concurrence no decrees concerning the whole Church could be made."[78]
