The Antidicomarians or Antidicomarianites, also called Dimoerites, were a Christian sect active from the 3rd to the 5th century. Their name was invented by an opponent, Epiphanius of Salamis, who described them as heretical in his Panarion. The existence of the Antidicomarians as an organized sect may be doubted, as it is attested only in Epiphanius, but the doctrines he attributes to them were certainly matters of live debate in the late 4th century, and were condemned as heresy by prominent Christians such as St. Augustine of Hippo, and St. Ambrose of Milan.
