The official list of titles of the pope, in the order in which they are given in the Annuario Pontificio, is:
Bishop of Rome, Vicar of Jesus Christ, Successor of the Prince of the Apostles, Supreme Pontiff of the Universal Church, Primate of Italy, Archbishop and Metropolitan of the Roman Province, Sovereign of the Vatican City State, Servant of the servants of God.
The best-known title, that of "Pope", does not appear in the official list, but is commonly used in the titles of documents, and appears, in abbreviated form, in their signatures. Thus Pope Paul VI signed as "Paulus PP. VI", the "PP." standing for "papa" ("pope").
The title "Pope" was from the early 3rd century an honorific designation used for any bishop in the West. In the East, it was used only for the Bishop of Alexandria. Pope Marcellinus (d. 304) is the first Bishop of Rome shown in sources to have had the title "Pope" used of him. From the 6th century, the imperial chancery of Constantinople normally reserved this designation for the Bishop of Rome. From the early 6th century, it began to be confined in the West to the Bishop of Rome, a practice that was firmly in place by the 11th century, when Pope Gregory VII declared it reserved for the Bishop of Rome.
In Eastern Christianity, where the title "Pope" is used also of the Bishop of Alexandria, the Bishop of Rome is often referred to as the "Pope of Rome", regardless of whether the speaker or writer is in communion with Rome or not.
Triregnum, also called the "tiara" or "triple crown", represents the pope's three functions as "supreme pastor", "supreme teacher" and "supreme priest". Recent popes have not, however, worn the triregnum, though it remains the symbol of the papacy and has not been abolished. In liturgical ceremonies the pope wears an episcopal mitre (an erect cloth hat).
Crosier topped by a crucifix, a custom established before the 13th century (see Papal ferula).
Pallium, or pall, a circular band of fabric worn around the neck over the chasuble. It forms a yoke about the neck, breast and shoulders and has two pendants hanging down in front and behind, and is ornamented with six crosses. Previously, the pallium worn by the pope was identical to those he granted to the primates, but in 2005, Pope Benedict XVI began to use a distinct papal pallium that is larger than the primatial, and was adorned with red crosses instead of black.
"Keys to the Kingdom of Heaven", the image of two keys, one gold and one silver. The silver key symbolizes the power to bind and loose on Earth, and the gold key the power to bind and loose in Heaven.
Ring of the Fisherman, a gold or gilt ring decorated with a depiction of St. Peter in a boat casting his net, with the pope's name around it.
Umbraculum (better known in the Italian form ombrellino) is a canopy or umbrella consisting of alternating red and gold stripes, which used to be carried above the pope in processions.
Sedia gestatoria, a mobile throne carried by twelve footmen (palafrenieri) in red uniforms, accompanied by two attendants bearing flabella (fans made of white ostrich feathers), and sometimes a large canopy, carried by eight attendants. The use of the flabella was discontinued by Pope John Paul I. The use of the sedia gestatoria was discontinued by Pope John Paul II.
In heraldry, each pope has his own personal coat of arms. Though unique for each pope, the arms have for several centuries been traditionally accompanied by two keys in saltire (i.e., crossed over one another so as to form an X) behind the escutcheon (shield) (one silver key and one gold key, tied with a red cord), and above them a silver triregnum with three gold crowns and red infulae (lappetstwo strips of fabric hanging from the back of the triregnum which fall over the neck and shoulders when worn). This is blazoned: "two keys in saltire or and argent, interlacing in the rings or, beneath a tiara argent, crowned or"). The 21st century has seen departures from this tradition. In 2005, Pope Benedict XVI, while maintaining the crossed keys behind the shield, omitted the papal tiara from his personal coat of arms, replacing it with a mitre with three horizontal lines. Beneath the shield he added the pallium, a papal symbol of authority more ancient than the tiara, the use of which is also granted to metropolitan archbishops as a sign of communion with the See of Rome. Though the tiara was omitted in the pope's personal coat of arms; the coat of arms of the Holy See, which includes the tiara, remained unaltered. In 2013, Pope Francis maintained the mitre that replaced the tiara, but omitted the pallium. He also departed from papal tradition by adding beneath the shield his personal pastoral motto: Miserando atque eligendo.
The flag most frequently associated with the pope is the yellow and white flag of Vatican City, with the arms of the Holy See (blazoned: "Gules, two keys in saltire or and argent, interlacing in the rings or, beneath a tiara argent, crowned or") on the right-hand side (the "fly") in the white half of the flag (the left-hand sidethe "hoist"is yellow). The pope's escucheon does not appear on the flag. This flag was first adopted in 1808, whereas the previous flag had been red and gold. Although Pope Benedict XVI replaced the triregnum with a mitre on his personal coat of arms, it has been retained on the flag.
