Christ is Born!
We live in very confused times. Nothing is taken seriously amongst those who deem themselves to be "civilized." Those left in the world who do take anything seriously (even if mistakenly - ex. Islamists) are not so much derided for what they believe, but how they believe it - it is this which disgusts us, more than any particular tenant of their belief systems.
It is with a similar disdain, that "civilized" western man, in his decadence and lukewarmness, views the confessing Orthodox Christian when he happens upon him.
Ecumenism, in it's varying shades, will always more so than not meet with the praise and approval of the world. It has all that the world desires - truth slain at the altar of "peace"; obstensible unity purchased at the cost of integrity. In a society like ours, the appearance of seriousness and (even more so) true piety, raises alarm.
Ecumenism is a pan-heresy, the most damning of all (for generally past heresies at least had that one characteristic of truth - integrity, seriousness amongst their adherants.) Ecumenism lacks even this. Those possessed of it's pathos are in the worst possible place, for not only do they not have the truth, but they have been rendered incapable (naturally speaking at least) of accepting it should they happen upon it.
Ecumenists will never understand the genuine Orthodox - it is not in their nature to do such. I suspect you'd have better luck finding understanding amongst Islamist fundamentalists, hard-core atheist-marxists, or outright satanists.
15 I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot.
16 So then because thou art lukewarm, and neither cold nor hot, I will spew thee out of my mouth. (Apocalypse 3:15-16)
