in ecclesiastical history, the name by which the pure Arians were called in the fourth century, in contradiction to the Semi-Arians. The word is formed from the Greek, ἀνομοιος, different, dissimilar: For the pure Arians affirmed, that the Son was of a nature different from, and in nothing like, that of the Father: whereas the Semi-Arians acknowledged a likeness of nature in the Son; at the same time that they denied, with the pure Arians, the co-substantiality of the Word.—The Semi-Arians condemned the Anomoeans in the council of Seleucia; and the Anomoeans in their turn condemned the Semi-Arians in the councils of Constantinoople and Antioch, erasing the word ὁμοιος, like, out of the Formula of Rimini and that of Constantinople.
