This is a little bit of a straw man, but I was thinking about it, so I thought I would post it to see what your thoughts are.
The Eastern Orthodox Church claims that they hold to the traditions of the Apostles, and that we should listen to them because they are pure and undefiled from the world. But is that true? One simple way to show that Orthodox tradition has changed is to take a look at the clothes that their priests are required to wear because they are not the same as they have always been. In fact, they have changed quite a bit (and even are different now based on region),  and few of these ornate clothes or their symbolism really existed until after Christianity was “standardized” during the age of Constantine. Far from being an Apostolic tradition, they made up their own tradition, and now hold to it as though it was directly from God. Their clothes are based on the tradition of men, not of God. If they can’t even get their clothes right, why should we believe they have anything else right?
“CHRISTIAN CHURCH VESTMENTS were not inherited from any other religion, but gradually evolved out of the ordinary dress of the elite in the Roman Empire. In those first days of Christianity the clergy presided in their ordinary clothing, although no doubt more costly and beautiful garments were used. The Church, therefore, did not invent vestments. Instead it simply retained some of the gracious and ample vesture once worn by the upper classes. As time went on and fashions changed, the Church kept the original styles, thus reflecting a feeling common to most religions that special clothing be used for ceremonial occasions.”
I don’t claim to have everything right, so saying I have one part of my theology wrong doesn’t hurt me, but rather would make me want to search the Scriptures more so that I may test to see whether my belief is based on truth or not. But because the Orthodox Church claims they have everything right, since I can prove they don’t have their clothes right (their tradition has changed, and yet they require their priests to conform to wearing certain vestments, or special clothing), I can prove that they are false in their claim of pure Apostolic tradition. If certain clothes are required by tradition, someone in the Orthodox Church is wrong, and they should find out who (is it the Greeks, the Russians?), so that they can return to the truth. But I believe they are wrong altogether – the Apostles did NOT wear the same ornate clothes that they now wear, and neither should we be required to.

 “The rise of Byzantium and the close relationship of the Church and State had a marked influence on the further development of Orthodox vestments which have essentially remained in the same form up to this day The mitre, for example,-worn by all those in the episcopal office-is modeled after the crown of the Byzantine emperors. .It is highly unlikely that it was modeled after the Old Testament mitre since it was not adopted by bishops of the Church until the 15th century.” – “The Symbolism of Vestments,” http://www.roca.org/OA/32/32f.htm.
