What we call the "Orthodox Church" was never subjugated beneath Rome, in fact, no other bishop rightfully should be--bishops are equal. Archbishops may lead regions, but they don't have authority over another bishop of a different region. If there are eve problems, a synod of bishops can concur to depose another who may be corrupt, but it cannot be done by any single bishop unilaterally. They lead, but don't rule over each other. Please study the collegial model of Church structure, which was the biblical model, as opposed to the innovation of a hierarchical model later invented by the Roman Catholic religion. Hierarchy may work in business, but not within Christ's one holy apostolic Church.
