Nevertheless, when Eustathius was deposed, the Arians or Eusebius of Nicomedia had everything their own way and admitted Eudoxius to orders and made him bishop of Germanicia, on the confines of Syria, Cilicia, and Cappadocia.
This bishopric he held at least 17 years, the period of the principal intrigues against Athanasius of Alexandria, and of the reigns of Constantine the Great's sons.
The majority signed the "Creed of the Dedication"; Eudoxius who was present, was deposed by Basil of Ancyra's party, and appears to have sought the shelter of the court at Constantinople.
On 15 February the great church of Constantinople, Saint Sophia, begun in 342 by the emperor Constantius II, was dedicated.
[2] Eudoxius, it is claimed, mounting his episcopal throne before the expectant multitude of courtiers, ecclesiastics, and citizens, began with the words: "The Father is asebes, the Son is eusebes."
Holding a meeting at Lampsacus, they signed the "Creed of the Dedication", cited Eudoxius and his party before them, and, as they did not come, sentenced them to deprivation; but Roman emperor Valens refused to confirm the proceedings.
[2] In 367 Valens, as he was setting out for the Gothic War, was induced by his wife Domnica to receive baptism from Eudoxius.
In the same year, he issued, likely under the advice of Eudoxius, an order that such bishops as had been banished by Constantius II and had returned under Roman emperor Julian should again be exiled.
