According to an answer to this question When did Peter become the first Pope, according to Roman Catholic doctrine?, the Pope is the bishop of Rome.
So this made me wonder - since Peter was ordained an Apostle (not bishop of Rome) and he is considered the first Pope - are bishops equal in authority with apostles according to Roman Catholic tradition?
I understand what apostolic succession is, but it doesn't seem clear from this that it's the actual apostolic authority or just a part of it handed down to the bishops from the original apostles.
