The Anomoeans [Gr., = unlike], followers of Eunomius and Aetius, were pure Arians and held that the Son bore no resemblance to the Father. The semi-Arian court party were called Homoeans [Gr., = similar], from their teaching that the Son was simply like the Father as defined by Scripture. A third party called Homoiousians [Gr., = like in substance] were largely prevented from joining the orthodox (Homoousian) party through a misunderstanding of terms. The Arians debated their differences at Sirmium (351–59). The final formula was an ambiguous Homoean declaration that Constantius imposed (359) on the church in two councils, Rimini (for the West) and Seleucia (for the East).
