That would be a near-impossible position to defend, I rather think.
Scholars now reckon the Decree of Thessalonika, issued by Theodisius in 380, was aimed at Constantinople, seat of semi-Arianism, and not the empire as a whole (where it had little impact) – so Theodosius never actually declared Christianity the State Religion.
Wikipedia:
Theodosius I (
Greek: Θεοδόσιος
Theodosios; 11 January 347 – 17 January 395), also called
Theodosius the Great, was
Roman emperor from 379 to 395. During his reign, he succeeded in a crucial
war against the Goths, as well as in two civil wars, and was instrumental in establishing the
creed of Nicaea as the orthodox doctrine for
Christianity. Theodosius was the last emperor to rule the entire
Roman Empire before its administration was permanently split between two separate courts (one
western, the other
eastern).
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?
Emperors tried various means of 'uniting' the church, and all of them failed.
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.
The Trinity, the confession of Father, Son and Holy Spirit, is as old as the Church.
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.
You'd have to clarify that point. Monophysitism in theological discussion applies the the doctrine from Antioch in the middle of the 5th century – that Christ's human nature was completely subsumed by His divine nature.
The term is indeed later. The Monophysite (=Miaphysit) position was represent in the council of Nicea mainly by Apollinaris of Laodicea.
I said: to meet half-way and to interprete the dogma in the one or the other sense.
Subordinationism is a trinitarian teaching, as is monophysitism, both were eventually rejected as orthodoxy emerged from the sometimes furious debates across the centuries – both declare Jesus is God.
You say, both are trinitarian teachings; so the goal to unite the positions has been successful in your mind at least. 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.
Ah, no, that's not correct at all.
And it was defended on Scriptural grounds, too ...
You can, if you pick them out and put scolarly opinions above citings of Jesus.
But we know Christianity did not follow polytheist mythology, so that's a popular fallacy.
I am not saying that Christianity followed polytheist mythology.
Not, that's quite wrong. Mary was never declared divine.
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.
Two out of three – not bad.
However Jesus is the Word incarnate.
I have explained my understanding of this, and you have read it.
