In my opinion, much of what you say is true.
Although I would not rule out actual longterm, masonic or otherwise conspiracy, I do think that most of the mess grows out of a desire to be accepted and other vain things such as politics. Or as my priest used to say, "its just the way some people think". He didnt like the idea of conspiracies.
I have one question though, about this:
"I think the real mental work has yet to be done on these important theological issues and we must remain open to solutions not one-sided rhetoric."
Do you refer to the theological issues of division within Orthodoxy itself or the theological issues of eccumenism? Obviously the theological issues of ecumenism are non-issues and quite stupid. I do not think the theological issues of Orthodox division require mental work, but martyrdom.
It is the lack of simple Love and Humility that divides a small group of Christians, and the lack of true repentance that divides them further, and I would submit that this also applies to larger groups, and even worldwide and in unseen realms, up to the division between demons and angels, God and man, man and woman, my idea of myself and the reality.
I am so pessemistic, and long to be cured. I am in a town with three Orthodox priests (of the same juristiction) who do not even talk to each other, and a handful of Orthodox Christians, most of whom speak to none of these priests, and who are divided amongst themselves. Sadly, almost all of them seem to truly believe that they have excellent reasons for splitting each other or avoiding one another and cannot percieve the weakness of the enemies webs in the face of God's Grace. I think the main problem is that ignorence, like Saint maximos says, is double edged. It is ignorence of both human weakness and Divine Power. Put simply, will he find faith? There is no human solution to this. In my own situatuion, by God's grace, I am on good terms with every priest and Christian I know. Sometimes I feel bad because i am the only one to benefit from the division of others, since the struggle to not be drawn into the nets of scandal and intriuge has taught me to pray, and revealed to me the un-reality of the enemies illusions.
Division is the outgrowth of fallenness. Fragmentation. I do not see how this can be reversed on a large scale when it is not being conciously reversed on the simple person to person scale. And the Orthodox often resemble the humanists who lament the steate of humanity, and claim to love the whole world, but hate the neighbor. But my experience is extremely limited, and so I have no real idea of what is going on. And if I do my prayers at night and morning and stay out of trouble, it doesnt worry me too much, although I fear I may perish for lack of guidance so please pray for me and my estranged brothers and sisters.
