Indeed, as the only leadership positions were (πρεσβύτερος=elder) or episkopos (ἐπίσκοπος=superintendent/overseers) and apostles and deacons, and none of which are titled hiereus (ἱερεύς=priest), which all believers are, offering up spiritual sacrifices, acceptable to God by Jesus Christ. (1Pt. 2:5,9)
Then we have the condemnation of love of title and praise, in Matthew 23:5-7: "But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments, And love the uppermost rooms at feasts, and the chief seats in the synagogues, And greetings in the markets, and to be called of men, Rabbi, Rabbi."
Contrary in spirit to this is the elaborate clerical garb in Catholicism and extended hierarchical levels, and love of titles, esp in Rome, with its Priests, Parochial Vicars Primates, Metropolitans, Archbishops, Diocesan bishops, Deacons, Cardinal bishops (being a cardinal by itself does not confer power of governance), Cardinal priests, Cardinal deacons Protodeacon, etc., and when announcing, "we have a Pope: the most eminent and most reverend lord, Lord Jorge Mario, Cardinal of the Holy Roman Church, Bergoglio" (but who has not signed his name "pope.").
