Papal ferula
The papal ferula (; Latin "ferula", 'rod') is the pastoral staff used in the Catholic Church by the pope. It is a rod with a knob on top surmounted by a cross. It differs from a crosier, the staff carried by other bishops of Latin-rite churches, which is curved or bent at the top in the style of a shepherd's crook. History. Early usage and dispute. Traditionally, the popes did not use any "ferula", crosier, or pastoral staff as part of the papal liturgy. The use of a staff is not mentioned in descriptions of Papal Masses  in the "Ordines Romani" (Roman Ordinals). In the early days of the Church a pope would sometimes carry a crosier, but this practice disappeared by the time of Pope Innocent III. Innocent III noted in his "De Sacro altaris mysterio" (“Concerning the Sacred Mystery of the Altar,” I, 62): “The Roman Pontiff does not use the shepherd's staff.” The reason was that a crosier is often given by the metropolitan archbishop (or another bishop) to a newly elected bishop during his investiture or episcopal ordination. In contrast, the pope does not receive investiture from another bishop and is invested  with the pallium during his coronation or the modern inauguration. Re-adoption. During the High Middle Ages, the popes once again began using a staff known as a "ferula" as insignia to signify temporal power and governance, which included "the power to mete out punishment and impose penances". The actual form of the staves from this period is not well known, but were likely staffs topped with a knob and a single-barred cross on top. The staff was not a liturgical item, and its use was limited to a few extraordinary ceremonial occasions, such as the opening of the  Holy Door and the consecration of churches, during which the pope "took hold of the staff to knock on the door three times and to trace the Greek and Latin letters on the floor of the church". Sometimes, the staff also took the form of a triple-barred cross (or papal cross, a symbol of the papacy), but this was rare in contrast to the single-barred cross. Use of the staff was soon again phased out. In 1877, the "Circolo San Pietro" (an organization founded in 1869 to support the papacy) presented a staff or "ferula" to Pope Pius  IX on the occasion of the fiftieth anniversary of his episcopal consecration, and is sometimes referred to as the ""ferula" of Pius IX". This "ferula" was used by popes from Pope Pius IX and his successors until Pope Paul VI, again only for extraordinary, non-liturgical ceremonies. Pope Leo XIII at times made use of a crosier in the same shape as that of other bishops. In addition, a triple-barred cross "ferula" was made for Leo XIII in 1888 for the Golden Jubilee of his ordination. Pope John XXIII had begun using the 1877 "ferula" of Pius IX for  various liturgical celebrations during the Second Vatican Council. It was during the pontificate of Paul VI that the popes more permanently began using a "ferula" as a pastoral staff for solemn liturgical celebrations, rather than a symbol of governance. In effect, the papal "ferula" became the equivalent of a bishop's crosier or pastoral staff. Modern usage. The pastoral staff carried by the popes since Pope Paul VI is a contemporary single-barred crucifix, designed by the Italian artist Lello Scorzelli in 1963 and carried and used in the same manner as a bishop uses his crosier. Paul VI had  actually used three other "ferulas", similar in style, with the other versions having a cross bar which was straight, or bent upward. Scorzelli's well-known version has the cross bar curving downward, much like the "paterissa" carried by a bishops of Eastern Catholic Churches. Paul VI first used this staff on 8 December 1965, at the closing of the Second Vatican Council. The Scorzelli staff was the one retained by his successors starting with Pope John Paul I. This "ferula" design is often associated with Pope John Paul II and is one of his identifying attributes of in religious  paintings and statuary. On 25 March 1983, Pope John Paul II used the "ferula" of Leo XIII with three horizontal bars in the opening of the Holy Door during the Jubilee, the Holy Year of the Redemption. In 1990, Scorzelli made a replica of the Paul VI "ferula" for John Paul II, which was lighter than the previous one. On 16 March 2008, at the Palm Sunday celebrations in Saint Peter's Square, Pope Benedict XVI used the "ferula" of Pius IX. This staff was used until 28 November 2009 at the First Vespers for Advent. A new "ferula" was  given to Pope Benedict XVI as a gift of the "Circolo San Pietro" and, according to Monsignor Guido Marini, the Master of Apostolic Ceremonies and head of the Office for the Liturgical Celebrations of the Supreme Pontiff, it "can be considered to all intents and purposes the pastoral staff of Benedict XVI." Pope Francis continued to use the "ferula" of Benedict XVI at the beginning of his pontificate. On 7 April 2013, at the Mass for the Possession of the Chair of the Bishop of Rome in the Archbasilica of Saint John Lateran in Rome, Francis returned to using the  1965 "ferula" of Paul VI with the corpus on it, and has since alternated its use with the "ferula" of Benedict XVI.
