Eusebius of Dorylaeum

Eusebius of Dorylaeum (Greek: Εὐσέβιος) was the 5th-century bishop of Dorylaeum (modern-day Eskişehir, Turkey), who spoke out against dissident teachings, especially those of Nestorius and Eutyches, during the period of Christological controversy. After succeeding in having them expelled from their positions, Eusebius was himself deposed and only reinstated two years later, after which the doctrine in dispute was more precisely defined.
