According to the canons of the Orthodox Church, at which point does a hierarch ascend his cathedra? That is, if he is elected by the flock of his diocese/metropolia/autonomous Church (where such elections are provided for) is he already considered to occupy his see? Or, will he assume his post only after his election is confirmed by the hierarchal superiors? Or esle, will he do so only after the enthronement ceremony (where such is provided for)? In different lists of hierarchs I have seen different dates marking the beginning of their tenure.
