The condemnation of phyletism (ecclesial nationalism) by the Orthodox Church at the Council of Constantinople of 1872:

Daniel Lossky's article focuses on the condemnation of phyletism — or ecclesial nationalism — issued by the Council of Constantinople in 1872 and on its contemporary relevance for Orthodox communities in the West. Drawing on personal theological reflection, the study examines the historical conditions under which this council defined phyletism as an ecclesiological heresy, before exploring its current implications. The central argument is that the proliferation of co-territorial Orthodox jurisdictions in the diaspora constitutes a concrete manifestation of the problem condemned in 1872. The article's contribution lies in its articulation of this conciliar precedent with the question of the canonical organization of Orthodox Churches outside their historical territories, proposing as a response the establishment of multiethnic and territorial episcopal structures capable of transcending national divisions within a single local Church.
