This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
A theological school entry records a named, identifiable body of doctrine and method associated with a particular teacher, council or tradition of teaching, considered for its distinctive positions on specific disputed questions and how those positions differ from a rival school within the same wider tradition, distinct from a denomination or a whole religious body in naming a documented line of theological argument rather than an institution. John Meyendorff's study, written from within the Orthodox tradition he documents, traces one such school's historical development and its specific positions on the filioque, purgatory and papal primacy against the differing Latin Western positions on the same disputed questions.
An entry records a school's documented distinguishing positions, the specific disputes those positions answer, and which rival school or tradition it is documented as differing from, since a theological school is defined at least as much by what it holds against as by what it holds.
An entry uses a school specific source for a school specific claim, since Meyendorff's own study documents Orthodox doctrine broadly across its communions and a claim about one particular autocephalous church's own institutional history needs a source dedicated to that church.
