5+ pages of a hot garbage thread... Yuk. That's time I won't get back in my life. To the OP:
What is the highest decisionmaking body in the Ecumenical Patriarchate?
In the OCA and the MP, the highest decisionmaking body is the All-American Assembly and Local "Sobor" assembly, respectively. The voting delegates are clergy and a few laity from the parishes. For example, an Assembly in 2008 voted to install Met. Jonah as the OCA's Metropolitan. Between assemblies, the Metropolitan Council or Holy Synod implements decisions and it's made of the primate (eg. Met. Jonah in 2008-2012) and leading bishops.
I think that's over-simplifying things. Generally speaking, Synods are the highest bodies within their respective autocephalous Churches, with specific functions possibly delegated to other groups (like the OCA's nomination for Primate).
I'm not familiar with the voting process in the EP for choosing Patriarchs. In the early years of the Cold War, the US arranged for a plane to bring Met. Athenagoras (an American bishop) to replace the contemporary Ecumenical Patriarch.
The US applied pressure on the election of that particular EP (who was Abp, not Met.), the Turkish state applied pressure also. In the subsequent election (of Pat. Athenagoras's successor) the US's pressure was rebuffed (both internally and externally). Generally, the prefect of Istanbul reviews the candidate list on behalf of the Turkish state and has the ability to strike names from the list; that list is then used by the Holy Synod to perform the election. (If you don't think that Athens, Jerusalem, and Moscow don't have similar issues / processes, I have a bridge to sell you...)
I can see that GOARCH might not elect its own hierarchs because GOARCH is under the EP instead of being autocephalous like the OCA is. The EP's leading hierarch Pat. Bartholomew appointed Abp. Elpidophoros to replace Abp. Demetrios as the GOARCH's hierarch in 2019.
Elections for Hierarchs within the family of the EP are the exclusive provenance of the Holy Synod of the Patriarchate. While the Patriarch can nominate and express (strongly) his preferences, there is still an election process that takes place.
This October, GOARCH is having Metropolitan-Clergy-Laity conferences on Zoom. The Metropolis of Chicago is having their Clergy-Laity Assembly in early October (
https://www.chicago.goarch.org/-/2021-clergy-laity). The Diocese of the Southeast is having their Fall General Assembly in October in South Carolina.
The GOA has a multi-level governance structure - for the Archdiocese/Eparchy as a whole:
- The Eparchial Synod, with the Archbishop as its President. (Remember - in the Greek practice Archbishops are presidents of Synods, the opposite of the Slavic practice.)
- The Archdiocesan Council (which includes all the members of the Eparchial Synod, and another 110-or-so persons)
- The Archdiocesan Clergy-Laity Congress (meets every other year)
Then each Metropolis has:
- Ruling Metropolitan
- Metropolis Council (26 voting members)
- Metropolis Clergy-Laity Assembly (meets either every year or every-other)
Each body has responsibilities delineated through the Charter (which, although we know it's being reissued, is still in effect mostly for the time being) and the Regulations.
What kinds of decisions and voting processes occur in these assemblies?
I am guessing that a lot of the decisions are budgetary. Maybe they would discuss how much money to put into the shrine at the WTC.
Differentiating between the Assemblies (in each Metropolis) and the Congress (the whole Archdiocese/Eparchy):
Metropolis Assemblies generally tackle their respective Metropolis budgets, audits of the prior years, elections to the Metropolis Council (16 of the 26 seats are elected, 11 appointed, and 1 is the Metropolitan himself), review of the Metropolis ministries, approval of purchase/sale/renovation of property (which must be ratified by the Archdiocese), etc.
The Archdiocesan Congress deals with budgets, audits, the Archdiocesan ministries, Regulations (amendments must come from either the Metropolis Assemblies or the Archdiocesan Council), etc.
Matters of Dogma / Faith, the operation of the Eparchial Synod, etc. are only dealt with by the Eparchial Synod & the Patriarchal Synod.
I heard a Q&A of a Laity conference where Abp. Elpidophoros stated that nonOrthodox spouses could commune. Since it was in a Q&A format, people asked about this, but there was no input as to whether members were agreeing with the new policy. In effect, the Archbishop was announcing the policy and people were asking for clarification instead of approving or rejecting the policy.
The Q&A was at the annual conference of Leadership 100 (an endowment supporting Archdiocesan ministries) - and his statement was surprise that we allow the non-Orthodox to participate in one sacrament (marriage) and not others. It doesn't make sense to him (as it doesn't make sense to a lot of Eastern Europeans). But no policy was issued or furthered.
In a recent decision, Abp. Elpidophoros announced that GOARCH was annulling any religious exemptions that its priests gave for vaccines. Before his decision, there had been some religious exemptions that GOARCH priests had given people who wanted to avoid the vaccines.
He announced a decision of the Eparchial Synod - which was basically to undercut the foundation of a religious exemption by saying that none existed. The priests who were issuing such exemptions were doing so without the blessing of their hierarchs (in most cases).
In the case of the EP's assertion of being the vertical supreme primate over the Orthodox world and the EP's use of this asserted power to recognize the Kiev Patriarch clergy and O.C. of Ukraine as canonical, I doubt that the GOARCH assemblies voted on these policies. It looks like the decisions would have been made in a top down fashion. Apparently the EP and the top EP synod of bishops would have made the decision and then GOARCH obeyed it. Some laity might agree, disagree, or not care, but they were not the decisionmakers.
I talked with a ROCOR priest of Greek heritage who studied in a GOARCH seminary in the US decades ago. He said that he and a major fraction of seminarians left the seminary the year that the seminary forced out Fr. John Romanides for teaching more traditional Orthodoxy. The priest told me that GOARCH was trying to make accommodations with the Protestant world at that time and he listed examples like Abp. Iakovos requiring priests to stop wearing beards and cassocks. I asked him if he could have gone to a GOARCH assembly and told people there about his concerns in order to address them, and he replied that GOARCH assemblies did not work like I was suggesting. He said that Greek Orthodox in the US could instead be informed about issues over time.
All of the above is a mess. Abp. Iakovos's "westernization" measures were not accommodations to Protestantism, but were trying to make the clergy seem less strange to the Americans they were supposed to be ministering to. I personally believe it was misguided - but I have the luxury of doing so, having grown up in a largely RC area where people see me in my cassock and assume I'm a Roman priest (and then I get to surprise them with my wedding ring). For clergy ministering in largely Baptist or Evangelical areas, and especially when the KKK was more menacing, it could be problematic (and this includes the incident from not-too-many years ago when a priest was assaulted within an inch of his life by a retired solider with PTSD who assumed he was an islamic terrorist).
So are GOARCH assemblies and clergy-lay conferences a top-down matter of the leadership informing the delegates about the policies that the leadership has already decided on and then the delegates get to vote on some issues where the outcome of votes are already practically decided?
I am guessing that the assembly decisions are not pre-decided or top-down on all issues. It seems that there could be budgetary issues where the leadership could leave it up to the delegates as to how much money they want to put in certain projects.
Suppose theoretically that the GOARCH leadership or EP holy synod was taking a strong, mistaken position on some issue or policy. Would the GOARCH membership have an opportunity to change course at Assemblies or Clergy-Laity Conferences?
I just think you're blurring the delineation between the matters of Church operation and the matters of dogma/faith. The All-American Council of the OCA can't make faith decisions, just as the GOA's Clergy-Laity Congress cannot. Synods make certain types of decisions, and Clergy-Lay bodies make other types. While some of the particulars are different between the GOA, OCA, AOA, etc., the larger principle is relatively stable here in the US.
