OK. All I was saying is that the Decree is not regarded as perhaps a local ruling. Theodosius was furious with an Arian bishop who flouted his decree in Constantinople, but he was notably not so much bothered by Arians outside the city. Certainly the prohibitions of the decree, ownership of property, etc, was not enforced with great vigour outside Constantinople.Wikipedia:
... and was instrumental in establishing the creed of Nicaea as the orthodox doctrine for Christianity.
He was, by all accounts, a fair and just man.
Arianism was not an issue in the West. It was seen as a local issue.He will well have had problems to reign over the western part, and it may not have been his first priority to unify the Christian dogmatics there. But which scholars suppose that Theodosius meant to make a difference in Religion over his empire?
Well to be fair there was no separation between East and West at this time. We weren't discussing the later Middle Ages.Both, the Greek Orthodox and Roman Catholic accepted and imposed the trinity dogma, and medieval emperors until the 18th centry succeeded to impose their faith in the empire.
I think we can assume Christians understood Jesus as God from apostolic times.Yes, the confession of Father, Son and Holy Spirit is common already in the 1st century Church. But that does not mean that everyone understood it as if Jesus (p.b.u.h) is a god; rather he and the Holy Spirit are sent out by Him.
No, Apollinaris was at Nicaea, a friend of Athanasius and an opponent of Arius. His own monophysite Christology was not a topic of discussion, there's no appearance of it until about 360AD.The Monophysite (=Miaphysit) position was represent in the council of Nicea mainly by Apollinaris of Laodicea.
They are entirely separate issues:But they are different from each other, and both positions deny that Jesus is both, god and human; subordinarism does not say that Jesus is God, others do.
Subordinationism is about the relation of the Son to the Father.
Monophysitism is about the relationship of the divine and human natures in Christ
Both affirm that Jesus is God.
Arianism was an extreme subordinationism that declared Jesus a God, but distinct from the Father. Within a few years of Nicaea, the view was largely rejected by semiArians.
Apollinaris taught that Jesus had a human body and a divine nature, but not a human mind or spirit, they being subsumed by the divine. (Rejected by a synod in Alexandria 362 and at the Council of Constantinople in 381.)
Nestorius, bishop of Constantinople in 428, taught Jesus had two natures so divided that He was actually two persons.
Another monophysite, of Eutyches, saw Jesus having one nature in which the human was fully absorbed by the divine and became a third kind of nature – more than human, but less than divine. A variation was that Jesus was fully divine, his humanity having been absorbed.
So we had monophysitism contra dyophysitism – Jesus is one person of one substance but with two different natures: one divine and one human. Miaphysitism subsequently emerged, stating Jesus is one person of one substance with one, fully integrated nature that is both fully human and fully divine.
I don't think Mary was ever regarded as divine by any other than one fringe sect on record, which I've dealt with. The Church is quite clear that Mary is human, not divine and not a figure of worship.Mary was not really declared divine but the term was used among early monophysite and trinitarian Greek Christians and it is still used in the Roman Catholic Church, and Catholics pray to Mary instead of God (which is definitely not based on the teachings of Jesus), see https://en.wikipedia.org/wiki/Theotokos.
