Why cant we have an Estonian solution? Russian nationalists directly under the MP;
normal and reasonable people of the MP would get a substantial autonomy under Constantinople (like Finland) and reunite with the schismatics, + Philaret would resign.
Because it is rational and makes sense. That's why.
Do we really need to leave more overlapping jurisdictions for future generations to fix?
An overlapping jurisdiction would be a minor evil, as opposed to schism. We already have two uncanonical churches in Ukraine, and it looks like there is a danger of one more schism. So, out of ikonomia, it would be good to have 2 canonical jurisdictions for now, as opposed to 1 canonical (but increasingly infested by heretical phyletism) and 2 or possibly soon 3 uncanonical.
As soon as the 2 canonical jurisdictions are established, things can cool down and normalise. In Estonia, it has gotten much better already. The two jurisdictions there now not only talk to each other, but concelebrate and share Holy Pascha.
