There are no more doctrines in defining Christ. The last was done by the Church, not the bible at the Council of Nicea.
I donāt know why you keep saying that the final doctrine(s) of Christ were finalized at Nicaea

. Thatās not Catholic teaching. And I already responded to this already in the Moscow Patriarch thread.
Beyond these 3 dogmas, there is no long standing faith tradition of believers to define as dogma. That is all.
I would have to disagree with your assessment that there are only 3 dogmas as defined by Papal Infallibility. For one thing, there is a disagreement on what the list of infallible Papal defined dogmas by theologians is. There are definitely two as defined post-Vatican I, but there are other bulls and letters that may also satisfy the requirements. I have no idea of the origin of the idea of there only being 2 or 3 dogmas. However a well respected view is that there can be 7 dogmas as per Papal Infallibility, which was the work of Klaus Schatz, SJ in the 80s, whose work I usually refer to regarding the papacy.
- Tome to Flavian/Tome of Leo, 449 AD
- Letter of Pope Agatho, 680 AD
- Benedictus Deus, 1336 (mentioned prior in What makes Catholicism true compared to Eastern Orthodoxy? thread)
- Cum Occasione, 1653
- Auctoreum Fidei, 1794
- Ineffabilis Deus, 1854
- Munificentissimus Deus, 1950
Note the word, āassumptionā. We can only assume Mary was gloriously taken into heaven, whether she was asleep or died.
Likewise I donāt see a conflict with Orthodox understanding of Mary either.
In practice they arenāt contradictory and just emphasize different things. However, the issue is the lack of dogmatic assertion that the Theotokos died in addition to being assumed, as Orthodox affirm it is part of the teaching that we must accept. For us, tradition is not divided by dogma, doctrine, etc., some which does not need to be believed to be a Catholic in good standing. For Orthodox, no such system exists so it is a problem in a way if there was a Orthodox that affirmed the Theotokos did not die. In our Liturgy, services, and prayers, we fully affirm she died, and hence lex orandi lex credendi. To be honest, this is a very minor issue compared to other teachings, but there is still some issue to be resolved on how the catholic faithful is to understand the teaching end of the Theotokosā life (and not limited to what is dogma) in contrast to how Orthodox accept the whole as authoritative tradition that should be accepted.
Beyond these 3 dogmas, there is no long standing faith tradition of believers to define as dogma. That is all.
And for this, just to be sure, dogma is not just limited to Papal infallibility, and other catholic authoritative teaching may also be dogma (and not just doctrine). Example, the teachings of the ecumenical councils which define the two natures of Christ, two wills, etc. Unless this is what you mean, but I find your wording ambiguous.
