Jermaine of Capua was a 6th-century bishop who served the people of Capua. He is most recognized for leading a diplomatic mission to Constantinople between 519 and 520, where he helped resolve the Acacian schism that had divided the Eastern and Western churches. As a prominent prelate, he acted as a key negotiator between the papacy and the Byzantine imperial court, successfully facilitating the acceptance of terms intended to restore ecclesiastical unity.
