Conclusion

The Homoiousians took a stance between that of the Homoousians, and heteroousians (meaning 'different substance', also called Anomoeans) such as Aëtius and Eunomius. At a council in 358 at Sirmium, at the height of the movement's influence, the claim was made that the Son is "like in all " (ὅμοιον κατὰ πάντα, hómoion katà pánta), while the use of οὐσία (ousía) or any of its compounds in theological discussion was strongly criticized but not abandoned, and the heteroousians were anathematized. This compromise solution, which was satisfying to both the Homoians and the Homoiousians, deliberately set out to alienate the more extreme Neo-Arians (heteroousians). It was successful in this intent but it remained as illegitimate in the eyes of the pro-Nicenes as ever and Basil of Ancyra declared that "that which is like can never be the same as that to which it is like".
