Well, I can tell you what happened with the new Patriarch of Alexandria. When our last Patriarch Petros VI, was assassi...killed in a helicopter accident in Greece last year, all the bishops of the patriarchate got together and voted for the top three candidates for the new position. Then, the metropolitans of the patriarchate had another secret ballot (for the three candidates), where they unanimously voted Theodoros, Metropolitan of Zimbabwe and Southern African, the new patriarch. Hope that answers your question.
Theodoros used to be my bishop - he has a beautiful voice.
