What name the new pope chooses can signal what's ahead

ROME — The first clue of the next pope's direction will be the name the winner chooses.

The announcement ''Habemus Papam'' — ''We have a pope" — from the balcony of St. Peter's Basilica is followed first by the revelation of the new pontiff's baptismal name, in Latin, followed by his papal name, wrought with meaning.

A Pope Francis II would signify continuity with the late pontiff's pastoral legacy and his prioritizing of the marginalized. Francis himself quipped that his successor would be John XXIV, after the progressive Vatican II-era pope. The most popular papal name of the 20th century, Pius, would be a clear signal that a traditionalist is taking back the throne of St. Peter.

''In the deepest recesses of their mind, when they start the conclave, everyone will walk in there with a name in their head," said Natalia Imperatori-Lee, chair of religious studies at Manhattan University.

History of papal names

For most of the Catholic Church's first millennium, popes used their given names. The first exception was the 6th century Roman Mercurius, who had been named for a pagan god and chose the more appropriate name of John II.

The practice of adopting a new name became ingrained during the 11th century, a period of German popes who chose names of early church bishops out of ''a desire to signify continuity," said the Rev. Roberto Regoli, a historian at Rome's Pontifical Gregorian University.

Only starting in the mid-20th century did new popes begin to choose names signaling the aim of their papacy, Regoli said.

''Even now, as we are waiting for the new pope, the name with which he will present himself will help us to understand the horizon towards which he wants to proceed," Regoli said.

Some names have been out of use for centuries, like Urban or Innocent.

''I don't think anyone will pick Innocent,″ Imperatori-Lee said, given the abuse and other scandals that have rocked the church. ''I don't think that would be the right choice."

Recent names

BENEDICT: Last chosen by German Cardinal Joseph Ratzinger, elected in 2005. Pope Benedict XVI said he wanted to pay homage to Benedict XV, who led the church during World War I and dedicated himself to healing the rifts of war, and to the 6th century St. Benedict, founder of Western monasticism, who helped spread Christianity throughout Europe. One of Benedict XVI's priorities was trying to revive the faith in Europe. ''If we get a Benedict, then we will know that the cardinals chose to see Francis as an anomaly," Imperatori-Lee said.

JOHN PAUL: The papacy's first composite name was chosen by Cardinal Albino Luciani in 1978 to honor Pope John XXIII, who opened the Vatican Council II process that reformed the Catholic Church, and Paul VI, who closed it. The name signaled a commitment to reforms, including sidelining the Latin Mass in favor of local languages and opening to other faiths, most significantly Judaism. John Paul I's papacy lasted just 33 days. Polish Cardinal Karol Wojtyla, who succeeded him, chose the name John Paul II.

JOHN: Chosen 23 times by popes, most recently in 1958 by Pope John XXIII. John can refer to St. John the Apostle, one of Jesus' 12 apostles and the author of one of the Gospels, or St. John the Baptist, the prophet who baptized Jesus. ''John the XXIII was a pope that no one expected a lot from, but had a colossal impact on the church," Imperatori-Lee said. ''So that could be a sign of what they want their pontificate to be like."

PAUL: Chosen six times, most recently in 1963 by Paul VI. St. Paul the Apostle spread the teachings of Jesus in the 1st century.

PIUS: It is associated with popes known for their traditionalist, anti-reform bent. Pius IX ordered the kidnapping of the Jewish boy Edgardo Mortara in 1858 and raised him Catholic in the Vatican after learning he had been secretly baptized by a housekeeper; Pius X was the early 20th century anti-modernist who inspired the anti-Vatican II schismatic group, the Society of St. Pius X; Pius XII was the World War II-era pope criticized for not speaking out sufficiently about the Holocaust. "It is now a name that is hostage to some Catholic groups that can be considered traditionalists," Regoli said.

A new pope is free to choose a name never used before, as Francis did.

''This would open a new season and could mean that his program is not in line with any of his predecessors, so an even more personalized program," Regoli said.

Imperatori-Lee suggested another name that might signal a continuation of Francis' legacy: Ignatius, for the founder of Francis' Jesuit order.
