:''One of the reasons '''the Eastern Orthodox do not claim to have had any ecumenical councils since II Nicaea''' is that they have been unable to agree on which councils are ecumenical. In Orthodox circles, the test for whether a council is ecumenical is whether it is "accepted by the church" as such. But that test is unworkable: Any disputants who are unhappy with a council’s result can point to their own disagreement with it as evidence that the church has not accepted it as ecumenical, and it therefore has no authority''".

P.S. : Am I being "''Anti-Catholic''" by adding this here? :-)
