AUDAEUS or AUDIUS, a church reformer of the 4th century, by birth a Mesopotamian. He was banished into Scythia, where he worked successfully among the Goths. The Audaeans cele brated the feast of Easter on the same day as the Jewish Passover, and they were also charged with attributing to the Deity a human shape, an opinion which they appear to have founded on Genesis i. 26. Theodoret accuses them of Manichean tendencies.
