Orthodox Church of Constantinople
Orthodox Church of Constantinople is a misnomer used to refer to the one of the sixteen autocephalous Eastern Orthodox churches that is headed by the Ecumenical Patriarch. Among Eastern Orthodox, the term Orthodox Church of Constantinople is not used. Instead, Ecumenical Patriarchate or even Churches of the Ecumenical Patriarchate are used by Orthodox Christians when referring to the jurisdiction under the Ecumenical Patriarchate.
The Churches of the Ecumenical Patriarchate consist of five archdioceses, three churches, one exarchate, 12 metropolises ("metropolis" is preferred use over "metropolitanate" within this particular Orthodox jurisdiction), and one diocese, each of which reports directly to the Patriarch of Constantinople with no intervening authority. In addition, three of the five archdioceses have internal metropolisis (16 in all), which are part of their respective archdioceses rather than distinct administrative entities, unlike the other metropolises.
