Eastern Orthodox opposition to papal supremacy

The Eastern Orthodox Church is opposed to the Roman Catholic doctrine of papal supremacy. While not denying that some form of primacy could exist for Rome's bishop, Orthodox Christians argue that the tradition of Rome's primacy in the early Church was not equivalent to the current doctrine of supremacy.

The test of authentic catholicity is adherence to the authority of the Church's Holy Tradition, and then to the witness of Sacred "Scripture", which is itself a product of the Church's aforementioned Holy Tradition. It is not defined by adherence to any particular See. It is the position of the Orthodox Church that it has never accepted the pope as de jure leader of the entire church. All bishops are equal "as Peter", therefore every church under every bishop (consecrated in apostolic succession) is fully complete (the original meaning of catholic).

Referring to Ignatius of Antioch, Carlton says

Contrary to popular opinion, the word catholic does not mean "universal"; it means "whole, complete, lacking nothing." ... Thus, to confess the Church to be catholic is to say that She possesses the fullness of the Christian faith. To say, however, that Orthodox and Rome constitute two lungs of the same Church is to deny that either Church separately is catholic in any meaningful sense of the term. This is not only contrary to the teaching of Orthodoxy, it is flatly contrary to the teaching of the Roman Catholic Church, which considered itself truly catholic.

The church is in the image of the Trinity and reflects the reality of the incarnation.

The body of Christ must always be equal with itself … The local church which manifests the body of Christ cannot be subsumed into any larger organisation or collectivity which makes it more catholic and more in unity, for the simple reason that the principle of total catholicity and total unity is already intrinsic to it.

Any changes to the understanding of the church would reflect a change in the understanding of the Trinity.

It is the position of Orthodox Christianity that Roman Catholic arguments in support of the teaching have relied on proofs from Fathers that have either been misinterpreted or so taken out of context as to misrepresent their true intent. It is the position of Orthodox Christianity that a closer examination of those supposed supports would have the effect of either not supporting the argument or have the opposite effect of supporting the counter-argument.
