but if they already accept everything that came from those councils, why would they make a council in the first place?
Councils of bishops were not new by the time of the First Ecumenical Council. The church had been having local councils of bishops for a long time. It was already a tradition of the Orthodox Christian church to do this.
The Ecumenical Councils were gatherings of bishops of the Roman Empire. As you know, the first one was called by Constantine. He had the empire pay for the transportation and lodging of the bishops.
For the emperor it was an important political concern. He was hoping to have a strong united Christian church for his empire. The Council (not by any means the first called by him, years before he had one gathered at Arles, which only included western bishops from the various regions, like Gaul and North Africa) was intended as a gathering of the sovereign bishops in the interest of strengthening and unifying them in purpose and belief.
By inviting everyone, it was like having many of the local councils meeting simultaneously. Each of the synods participating were in effect dealing with the same issues at the same time as the other synods. It is a powerful image, if the Holy Spirit of God is present at a local council guiding and inspiring the bishops, how much more so if the local councils are sitting together.
There must have been well over one thousand bishops in the empire by this time, and dozens if not hundreds of more outside of the empire. But only a few hundred bishops actually attended, and many Metropolitans and bishops sent representatives to speak for them and report back on the matters discussed.
Many parts of the church were not well represented. For instance, we know that there were already Christians in India and Persia by this time, and Armenia had been Christian before the Roman Empire but not many (if any) were attending the Council at Nicea. Also less bishops from the west.
Those bishops from outside the empire who heard about it, and could make the trip in a timely fashion were of course, welcome.
Afterward, the local synods of the empire were asked to adopt the findings of the Council after it was complete and copies were sent out. All of the Metropolitans were invited to implement (and ratify) the Council findings. The members of the Council did not desire that something important would be decided among them that was not accepted by the remote churches.
I think the one biggest issue of the first Council was the teachings of Arius. The Council decided that his views were not Apostolic.
i mean they allready believe in what that council would reveal, what would be the point in holding the council?
The Council does not reveal anything new, the age of revelation has long been closed. It rejects false teaching.
they all agree on the sign of cross, but they didnt make a council for that,
This is not a theological matter, as such. It is a devotional practice that follows upon theology.
though this seems prety important for me, i hardly could believe that after 1054 the Church didnt need any Ecumenical Council in order to asure that its teachings are infallible.
The church is infallible in itself. Everyone is interested in preventing portions of the church from diverging, and there is a natural conservatism in the church overall. In other words, Orthodox bishops would prefer “to err on the side of caution” if you can understand my meaning.
If new teachings infest the church, a Council will be called to deal with it. It just so happens that there has not been a pressing need for that. No big new doctrines being presented by anyone from within the Orthodox communion.
The church has continued to hold local councils to deal with housekeeping issues. This, as I stated above, has been the longstanding tradition from before Nicea I.
There has been discussion off and on for a long time about bringing another Ecumenical Council together, but Orthodoxy is not really divided by any serious doctrinal threats, so it would be mainly a housekeeping kind of thing. Not really a crises management theological gathering.
