High Quality Content by WIKIPEDIA articles! The appointment of bishops in the Catholic Church is a complicated process. Outgoing bishops, neighbouring bishops, the faithful, the apostolic nuncio, various members of the Roman Curia, and the pope all have a role in the selection. The exact process varies based upon a number of factors, including whether the bishop is from the Latin Church or one of the Eastern Catholic Churches, the geographic location of the diocese, what office the candidate is being chosen to fill, and whether the candidate has previously been ordained to the episcopate.
