Well the monarchial structure, is all wrapped in with Petrine authority. So that’s all wrapped in together.
Where’s the source for permitting remarriage? I have heard this allegation previously, but not from the Orthodox.
The eschatalogical issue is not something I’ve heard previously. Where do they say this?
"The church gives one marriage, but will make the exception and tolerate up to a third marriage for any Orthodox Christian."
You can Google further yourself, "Indissolubility of marriage Eastern Orthodox 3rd marriage", or something along those lines.
