Is Orthodoxy the "True Church"?

A commentator at OnePeterFive asserted that "Orthodoxy was the one true Church." I wrote the following in answer:

I want to be kind, I do. However, I must write the following:

You are not serious, sir, when you write: "The Orthodox Church is the one true Church." That's absurd.

I submit this is manifestly untrue, manifestly so. There are 14 autocephalous Churches, self-governing, "sovereign" in their own rights, and the Patriarch at Istanbul is only a nominal figure -- even the Greek Orthodox Church refuses to allow him any hand in their government. (They're governed by a Holy Synod, as was the Russian Orthies from Peter the Great -- "The First Peter" -- until after the Revolution, when the Soviets revived the office -- what a great foundation for a Patriarchal Office).

So which of the 14 is the "True Church"? The question answers itself. They all fight among each other like cats and dogs, "uniting" only to oppose the Western Church, and were it not for the "Black Death" that swept through the Western Church post Vatican II, leaving, as did the original contagion, devastation behind: empty churches, etc., Orthodoxy would still be what it inherently is: ghetto ethnic Churches. Or one can say were it not for the huge Russian Orthodox Church, the total population of "the Orthodoxies" is negligible. Their membership consists almost entirely of ethnics, and a handful of disgruntled Catholics like Rod Dreher, who joined the Russian (i.e. its American doppelganger) Church and idealistic Protestants, such as Frank Schaeffer, son of the famous Protestant author Francis Schaeffer.

Yet another aspect of this that only the Antiochan Orthodox Church could be said to be "founded" by an Apostle (Peter, who traveled back and forth between Rome and the East a number of times). The Greek Church, as noted above, has no Patriarchal holder now. Istanbul, formerly Constantinople, a.k.a. Byzantium, when it rose to be the imperial capital, CLAIMED St. Andrew founded it, but that claim has no tradition behind it in those first centuries, UTTERLY unlike Peter and Paul being martyred at Rome.

And the Antiochan Church is basically the Syrian Orthodox Church, a ghetto Church in Damascus. Antioch itself, the "Queen of the East" is an empty ruin just inside Turkish Territory.

The Coptic Church's first patriarch was St. Mark, not an Apostle, but rather St. Peter's associate and secretary. Jerusalem itself was a center of the Faith only for a short time, with the Jews killing off or driving out followers of "the Way" before the Romans erased the city 4o years after the Crucifixion, and rebuilt it as Aelia Capitolina, which in its turn was never rose as high as Rome (or eventually Constantinople), before the Arabs conquered it and renamed it Al-Quds.

So, saying Orthodoxy is "the true Church" is conspicuously, strikingly, outstandingly wrong on every level.
