Doc, when the Orthodox Church intrudes into the lives of its laity, absent a dogma from a council (which is inapplicable here)the most it would do is promulgate a disciplinary canon...and that can be changed even by something as simple as disuse. The Orthodox system is NOT the Roman system. Our theologians talk about theology all the time, our synods and individual hierarchs issue encyclicals on all sorts of matters, but none of them have the force of anything unless they are a sort of disciplinary canon. To say this is a matter of “moral theology” is meaningless in terms of any consequences for Orthodox Christians. I understand you think we should follow the Roman course, which as you know was recommended against by +Paul VI commission on the subject, but we don’t and probably won’t.
Can the Orthodox teaching on homosexuality change too?
Is sacramental marriage a disciplinary canon too?
I don't care if you follow Rome or not, but you should follow the continuous universal teachings of Christianity from the time of the Apostles.
