Felix of Byzantium, a notable presbyter, served as the bishop of Byzantium from one hundred thirty-six to one hundred forty-one. His tenure marked a significant period in the early Christian church, as he succeeded the esteemed bishop Eleutherius of Byzantium.
During his five years in office, Felix navigated the complexities of ecclesiastical leadership under the reigns of Roman emperors Hadrian and Antoninus Pius. His leadership was characterized by a commitment to the growth and stability of the Christian community in Byzantium.
Following his departure from the bishopric, Felix was succeeded by Polycarpus II of Byzantium, who continued the work of fostering the faith in a time of both challenge and opportunity for the early church.
