One thing is quite certain, the Orthodox will continue to reject the filioque until the end of days.
"One thing is quite certain, the Orthodox will continue to reject the filioque until the end of days."
That's right. So the trick for Rome is to find a way out of the filioque, which its theologians went a long way to accomplish in DC 2 years ago, or forget any reunion with us and, incidently, probably lose some of their Eastern Rite Churches (they've pretty much lost any semblance of control over the Melkites already and the Ukrainians will be next). Hard as it sounds, when comes to issues like this, only an ecumenical council can resolve them and there will be no such council until some pope agrees to preside at one in the manner of the pre-Schism popes, and even then the lower clergy and laity will have to receive and accept any decision...or leave.
