is the name given to those who believed that Christ has a “like substance” of God (homeosius) but not the same substance (homoousius). The key figure of this group is Basil of Ancyra (356 a.d.).

St. Athanasius, after his return from exile, was able to convince them that Christ is “like” substance, meaning that He is like in every aspect and hence homoousius. Many accepted his point of view and were reconciled to the Orthodox Church.
