List of Universally Accepted Authoritative Synods After the Seven Ecumenical Councils

[Agios_Irineos]

Also, it is worthy of note, that many GOC/TOC groups would consider the Photian and Palamite councils to be Ecumenical, thus holding that there are nine, not seven, Ecumenical Councils.

[BenjaminMcCraw]

Master bless! I listed all of the councils that I know of after the Seventh Ecumenical Council that teach doctrine that all the Orthodox accept. I know that the Photian and Palamite synods are sometimes referred to as the Eighth and Ninth Ecumenical Councils as you brought up. On that topic there is something I do not know that I would be grateful if you could teach me. I generally understood a synod is an Ecumenical Council only if it has all three of these traits.

1. Called by the Roman emperor, thus "Imperial" or "Ecumenical" or "Oikoumenē" the whole inhabited Christian world under the Emperor
2. Taught something specific in the true orthodoxy faith, that is what was believed by everyone, always, and everywhere. But defining it in new more precise terms against a new heresy that perverted the faith as taught by the apostles and their disciples and so on
3. The definitions and anathemas of this council is accepted by the entire Orthodox world, that is every autocephalous and autonomous synod of bishops and their flocks

By that definition why is it only the Photian and Palamite synods are also considered Ecumenical? Why are these synods not considered Ecumenical?

861 Synod of Constantinople (First Second Council)
1082 Synod of Constantinople
1157 Synod of Constantinople (Blachernæ)
1166 Synod of Constantinople
1285 Synod of Constantinople (Blachernæ)

Their definitions and anathemas are in the Synodikon of Orthodoxy, what am I missing Master?

[Agios_Irineos]

An Ecumenical council generally is marked by resolution of a Christological/Trinitarian controversy dividing the Church. This is true of the Photian councils with rejected the Filioque, and the Palamite councils which resolved the Balaamite attacks on energies/essence of God.

You could contrast this with the 1082 Council you mentioned which condemned a philosopher for heretical philosophies that touched on matters of Christian belief.

[BenjaminMcCraw]

Thank you for your instruction! I dug into the question further based on what you said and I found some new things, there are nine possible synods in question. Two of them (861 and 1082) are not explicitly dealing with Trinitarian or Christological heresies but all the others do. So why don't we count the others as Ecumenical Councils?

For some more context

1110 Synod? (Probably in Constantinople)

[Agios_Irineos]

Benjamin,

The Lord bless you. Look at your list.

How many of those were roiling the church versus being peculiar local disputes? I didn't say just a christological/trinitarian controversy/heresy, but one that was dividing the Church. I believe there is a world of difference between "“The whole world groaned and marveled to find itself Arian" and some pesky Slavic gnostics confusing the local peasants. Local councils resolve local disputes.

How many of them were rehashes of previous decisions (i.e. double procession)? How many simply affirmed or compiled that which was done before?

How many were addressing issues from outside the Church (gnostics/Bogomilism)? Every one of the 7/9 Ecumenical councils dealt with issues coming from inside the Church -- heretics (those in the church who departed the faith) purporting to teach heresy as orthodoxy.

How many consisted of bishops of a single synod, versus a broad representation of the Church?

A local council can still be right and authoritative and not be ecumenical. They can be very important, like the Council of Jerusalem in 1672. They don't have to be ecumenical to have import and meaning.

[BenjaminMcCraw]

I appreciate your responses and I ask your patience Master as I ask a further clarifying question. I seek as much clarity and consistency of thought as we can have in our station in this life. I accept all Ecumenical and local councils accepted by the whole church as vital in the doctrines they teach and the way of life they show through the canons. My goal in understanding what is an Ecumenical Council is to have a better appreciation of the prayers of the church that make this distinction, not to devalue the local synods. If at the end of the day the answer is "Because the church says so" I would accept that convention. I do want to better understand the distinction of an Ecumenical Council if that is not the case as best as I can with your knowledge. The criteria laid out in this discussion so far is this.

Called by the Emperor for the Christian Empire
Accepted by everyone not on trial
Christological/Trinitarian Heresy
Major controversy that rocked the Church
Heretics from within not parasynagogues from without
Effected a major part of the empire not just locally
Bishops involved from many synods not just one
Not rehashed

This list does make all of the synods local between the Seventh, Eighth, and Ninth. However I have a question about the criteria of "Not Rehashed", does this not disqualify the Second and Fifth Ecumenical Councils? As they were primarily rehashing Arianism and Nestorianism respectfully? If we remove this criteria then all but two of the other synods would be local, but Synod of 843 and the Synod of 1285 would meet these criteria except being rehashed Iconoclasm and the Filioque respectfully. What quality does Second and Fifth that 843 and 1285 does not have? I appreciate your time and the effort you have put into answering my questions, I do feel this is helping me reach a deeper understanding.

Your blessings Master
