ROME (AP) -- Matthew Festing -- aka His Most Eminent Highness The Prince and Grand Master of the Knights of Malta -- bounds into the sitting room of his magnificent Renaissance palazzo sweaty and somewhat disheveled, and asks an aide if he should take off his sweater to be photographed.
Garrulous and self-effacing, Festing embodies some of the paradoxes of a fabled Catholic religious order that dates from the medieval Crusades: Steeped in European nobility and mystique, the order's mission is humility and charity -- running hospitals, ambulance services and old folks' homes around the globe. It has many trappings of a country, printing its own stamps, coins, license plates and passports, and yet -- a stateless state -- it rules over no territory.
The Sovereign Military Order of Malta's world headquarters, down the block from the Spanish Steps and with an Hermes boutique on the corner, features reception rooms draped in oil portraits of grand masters past and a gem of a chapel where King Juan Carlos of Spain was baptized by the future Pope Pius XII. On the ground floor, it runs a health clinic that, while private, provides free services for anyone who can't pay.
"It is, I suppose, a series of contradictions," Festing told The Associated Press ahead of the order's 900th birthday this week. "I'm on the inside of it, so it doesn't seem to be contradictory to me, but maybe it is."
And as the Sovereign Military and Hospitaller Order of St. John of Jerusalem of Rhodes and of Malta, as the group is officially called, celebrates the anniversary on Feb. 9 with a procession through St. Peter's Square, a Mass in the basilica and an audience with Pope Benedict XVI, the ancient order is confronting some very modern-day issues.
Once drawn exclusively from Europe's nobility, the order is trying to shed its image as a purely rich man's club while still tapping the world's wealthy to fund its charitable work. And though its military past is well behind it, the order is waging real legal battles to fend off what it says are impostors seeking to piggyback on its name to con people out of money.
Festing, a 63-year-old Briton and former Sotheby's auctioneer, is expansive about the unusual attributes of his organization of 13,500 Knights and Dames who make promises to be good Christians and fund the order's humanitarian work.
"On the one hand it's a sovereign entity. On the other hand it's a religious order. On the other hand it's a humanitarian organization. It's a complicated mixture of things," he says in an interview in the gold silk brocaded state drawing room between meetings with parting Vatican nuncios and visiting ministers, diplomatic receptions and silent prayer.
The order traces its history to the 11th century with the establishment of an infirmary in Jerusalem that cared for people of all faiths making pilgrimages to the Holy Land. It is the last of the great lay chivalrous military orders like the Knights Templars that combined religious fervor with fierce military might to protect and expand Christendom from Islam's advance during the Crusades.
In February 1113, Pope Paschal II issued a papal bull recognizing the order as independent from bishops or secular authorities. That "birth certificate," as Festing calls it, is the legal basis for asserting the order's sovereignty and the reason for Saturday's anniversary celebrations at the Vatican.
Festing himself is a "Professed Knight" -- the highest rank of members who take vows of poverty, chastity and obedience. The poverty vow seems a bit relative in this context: Knights on the order's governing council have their own private apartments inside the palace, complete with a valet and driver for cars that carry either diplomatic plates or the order's own SMOM plates. Wine from the order's own vineyards is often served.
Pope Benedict XVI is among the professed knights, though he's an exception since professed knights aren't ordained priests and traditionally descend from noble blood.
Festing, whose family traces their ancestry to 14th- and 16th-century knights, was elected grand master in 2008. It's a title he holds for life and is equivalent to the rank of cardinal, though he can't vote in a conclave to elect a pope.
Currently there are about 60 professed knights and Festing hopes to increase their numbers as he seeks to expand the rank-and-file base to a younger generation of equally Catholic but not necessarily noble classes around the globe.
"It's not exactly out of date, but you can't maintain that in the 21st century," he says. "In general terms, in the old countries of Europe, we maintain the nobiliary requirement to an extent. But only to an extent. But in places like Australia, Central America, North America, Southeast Asia, it's all done on a different basis."
