Where is your proof? I've never heard any quotes from the Church Fathers about those subjects, only from men like Tim Lahaye, and Ed Hindson.
Rome fell 1000 years ago... And I seriously doubt many more Patriarchates will fall, as there will be a church for Christ to come back to... Which I doubt will be just one Patriarchate...
Nigula, are you amillinialist? Do you ascribe to the Protestant ideas about eschatology?
And BTW, we need to strive for UNITY with other Christian churches... Schism is wrong... However I believe there is a difference between unity w/o conditions for the schismatics/heterodox and unity with the renouncement of doctrines by the heterodox.
Are you opposed to ANY unity with the Roman Catholics or Protestant Churches?
Also, your name says you are "Orthodox Christian" But could you be more specific?
