Some, including some fundamentalist Christians, condemn the ecumenical councils for other reasons. Independency or congregationalist polity among Protestants may involve the rejection of any governmental structure or binding authority above local congregations; conformity to the decisions of these councils is therefore considered purely voluntary and the councils are to be considered binding only insofar as those doctrines are derived from the Scriptures. Many of these churches reject the idea that anyone other than the authors of Scripture can directly lead other Christians by original divine authority; after the New Testament, they assert, the doors of revelation were closed and councils can only give advice or guidance, but have no authority. They consider new doctrines not derived from the sealed canon of Scripture to be both impossible and unnecessary whether proposed by church councils or by more recent prophets. Catholic and Orthodox objections to this position point to the fact that the Canon of Scripture itself was fixed by these councils. They conclude that this would lead to a logical inconsistency of a non-authoritative body fixing a supposedly authoritative source.
