The chief or supreme pontiff; specifically, the Pope or the highest religious authority in a faith.
Arch- plus pontiff (from Latin pontifex, a priest or bridge-builder). This term emerged in religious texts, though 'pontiff' itself alone became the standard term for the Pope.
Early Christian writers sometimes used 'archpontiff' as an even grander title for the Pope than 'pontiff' alone—it emphasized his supreme religious authority over all other clergy.
