The Ecclesiastical History of Socrates Scholasticus

But Eusebius did not live to learn the decision of Julius concerning Athanasius, for he died a short time after that Synod was held. Whereupon the people introduced Paul again into the church of Constantinople: the Arians, however, ordained Macedonius at the same time, in the church dedicated to Paul. This those who had formerly co-operated with Eusebius (that disturber of the public peace) brought about, assuming all his authority. These were Theognis, bishop of Nicæa, Maris of Chalcedon, Theodore of Heraclea in Thrace, Ursacius of Singidunum in Upper Mysia, and Valens of Mursa in Upper Pannonia. Ursacius and Valens indeed afterward altered their opinions, and presented a written recantation of them to bishop Julius, so that on subscribing the doctrine of consubstantiability they were again admitted to communion; but at that time they warmly supported the Arian error, and were instigators of the most violent conflicts in the churches, one of which was connected with Macedonius at Constantinople. By this intestine war among the Christians, continuous seditions arose in that city, and many lives were sacrificed in consequence of these occurrences.
