The Roman Catholic, [Orthodox Christian]?, and Anglican Churches hold that apostolic succession is maintained through the ordination of bishops in unbroken personal succession back to the apostles. The Roman Catholic church notably denies that the Anglican Churches practice valid apostolic succession.
Most Protestant churches maintain that their bishops and priests, although they do not trace a succession of ordination back to the apostles, are the spiritual successors of the apostles by faith the inspiration of the Holy Spirit (an extension of the Lutheran doctrine of sola fide).
