Wow it gets complicated
Are these bishops appointed by the pope as a laten bishop is?
If not explain how this is in line with apostolic succession
Not saying it isn’t im just not undestanding
Thanks
Patriarchal and Major Archiepiscopal churches Patriarch or Major Archbishop may appoint and/or ordain bishops within their traditional territory generally without interference from Rome, by their particular law. Outside their traditional territories, they are to run the appointment by Rome before installation; in either case, Rome can veto, but seldom does.
In the case of Metropolitan Churches, the Synod sends forward 3 candidates; the pope (almost always) picks one of these. In the rare instance that Rome rejects all 3, they advance a different set.
In the case of an Eparchial Church, the council of clergy elects three candidates, and sends them to Rome. Rome usually appoints one of those three.
In the case of Exarchial churches Sui Iuris, Rome appoints the Exarch. (Note that some Exarchial Churches are appointed by the Patriarchs of Patriarchal churches.)
In the case of the Russian Church, the Exarchial throne is vacant, and each parish is assigned to a Roman Church hierarch.
Erecting and suppressing of eparchies and metropolitanates follows much the same pattern:
Within a Major Archbishop’s or Patriarch’s traditional territory, he may do so by notifying rome. Outside, he consults with Rome, and usually the overlaping bishops of other churches.
Metropolitan, Eparchial, and Exarchial churches do not get to erect or suppress eparchies/exarchies; they ask Rome to do so on their behalf.
Note also: An Exarch is often not of the church he rules; many have been Roman Church auxiliary bishops. A few have been Ukrainian Auxiliary Bishops. And a couple were not even bishops!
The OCA and the Russian Orthodox, while not Catholic, generally have a council which elects a candidate, and that candidate is forwarded to the synod for approval. Upon approval, they are then ordained and enthroned.
