Many think that Arianism involved solely the eternal subordination of the Son in being/nature/essence. This is not so. All the Arians subordinated the Son in being and authority. The two were correlated by the Arians, who advocated both, and by the Nicene theologians, who rejected both. Both sides agreed they were two sides of one coin. If the Son is subordinate in being, he is subordinate in authority; if he is one in being with the Father, then he is one in authority.
