Pope Leo XIV received two lambs on the liturgical feast day of St. Agnes, continuing an ancient Roman Church tradition. The lambs were blessed in the Basilica of St. Agnes Outside the Walls, where the 4th-century martyr is interred. The wool from these lambs will be used to create the Pallia, liturgical insignia worn by the Pope and Metropolitan Archbishops. The tradition of blessing lambs on St. Agnes' feast dates back to the 6th century and is linked to a legend about the saint. Historically, the two lambs were also considered a form of 'rent' paid by the monks of St. Agnes' Basilica to St. John Lateran.

Pope Leo XIV received two lambs in the Vatican's Urban VIII Chapel on January 21, 2026, marking the feast of St. Agnes.1 2
The lambs, placed in baskets to keep them secure, were later blessed at the Basilica of St. Agnes Outside the Walls in northern Rome, where the saint is buried.1 2
This event added a traditional highlight to the Pope's general audience day.2
The wool from these lambs will be sheared by Benedictine nuns at the Basilica of St. Cecilia in Trastevere.1 2
It is used to craft pallia—white woolen bands adorned with six black silk crosses, symbolizing pastoral authority and communion with Rome.1 2
The Pope imposes pallia on new metropolitan archbishops on June 29, the feast of Saints Peter and Paul.1 2
The custom dates to at least the 6th century, linked to a legend where St. Agnes appeared to her parents post-martyrdom, holding a lamb as a symbol of purity.1 2
Historically, lambs served as "rent" paid by monks of St. Agnes Basilica to St. John Lateran, then presented to the Pope.1 2
For centuries, they came from the Trappist Abbey of the Three Fountains and were sheared during Holy Week.1 2
Modern changes include the closure of the Trappist sheep farm and the Pope no longer blessing lambs directly at the Vatican.1 2
Benedictine nuns continue preparing the wool for pallia despite these shifts.1 2
St. Agnes, a 4th-century Roman virgin martyr killed around 305 AD at age 12 or 13, possibly by sword, is one of Rome's most venerated saints.2
Her tomb along the Via Nomentana inspires the ongoing tradition.1 2
Investigate the theological significance of the St. Agnes lamb‑blessing tradition
The lamb-blessing tradition on the feast of St. Agnes (January 21) holds profound theological significance in Catholic liturgy and symbolism, intertwining the saint's virginal purity with Christological imagery and the Church's hierarchical communion. Two white lambs are solemnly blessed during the Mass at the Basilica of St. Agnes on the Via Nomentana in Rome, their wool later woven into the pallia—woolen bands bestowed upon metropolitan archbishops as signs of unity with the See of Peter. This practice, rooted in medieval devotion, evokes St. Agnes' innocence (from the Latin agnus, lamb), prefigures Christ as the Lamb of God, and underscores the shepherding mission of bishops in ecclesial communion.
The custom of associating lambs with St. Agnes emerged in the Middle Ages, building on her ancient iconography. Since early Christianity, Agnes—a Roman virgin martyr of about twelve or thirteen years old, slain around 304—has been depicted with a lamb and palm, symbolizing her virginal innocence and martyrdom. By the Middle Ages, this evolved into the annual blessing of two live lambs on her feast day. As described in hagiographical accounts, while the choir sings the antiphon Stans a dextris ejus agnus nive candidior ("On her right hand a lamb whiter than snow"), the lambs are presented at the sanctuary rails, blessed, and raised until shearing.
This rite ties directly to the pallium, a liturgical vestment whose wool derives from these lambs. Popes have conferred it on metropolitan archbishops since the ninth century, requesting it from the Bishop of Rome as a sign of "unity and full communion with the See of Peter’s Successor." The pallia are stored near St. Peter's tomb in the Vatican Confessio and blessed on the vigil of SS. Peter and Paul before distribution. Historical evidence from sacramentaries and the Depositio Martyrum (354) confirms Agnes' feast prominence, with the lamb tradition solidifying as a bridge between her cult and papal symbolism.
At its core, the lamb-blessing reveals deep Christological meaning, portraying Christ as both sacrificial Lamb and Good Shepherd. Pope John Paul II emphasized: "The lambs symbolize Christ, the Lamb of God and the Good Shepherd. As the sacrificial Lamb, he gave himself completely on the Cross for our salvation. As Shepherd he leads the flock to safe pastures and goes after the sheep which have strayed." The white lambs' purity mirrors Agnes' chastity but ultimately points to the Paschal Lamb—Jesus himself—who fulfills Old Testament typology.
This aligns with patristic and medieval exegesis, where scriptural realities (e.g., the Passover lamb) signify Christ beyond their literal sense. St. Agnes' lamb, therefore, is no mere pun on her name; it sacramentally recalls the "actual lamb of the Passover" as a sign of Christ, presupposing its historical reality while extending to its fulfillment. The blessing rite thus participates in the Church's liturgical symbolism, where created things (wool, lambs) convey divine mysteries, adapting to human intelligence under God's authorship of salvation history.
Theologically, the pallium forged from St. Agnes' lambs embodies ecclesial unity and jurisdictional authority. Worn over the shoulders like a yoke, it signifies the metropolitan archbishop's bond to the Pope, deriving from "the body of Blessed Peter." Vatican II echoes this: bishops are "sent by the Father to govern his family... by his prayer, preaching and all the works of charity" (Lumen Gentium 27).
The Pallium therefore, as well as being a sign of jurisdictional power in the Church, has a profound spiritual meaning for the Metropolitans concerned, and for the communities.
This tradition reinforces the Church as Christ's flock, with archbishops as under-shepherds. The lambs' journey—from Agnes' basilica to Peter's tomb to global archdioceses—symbolizes the flow of grace from martyrdom (Agnes) through apostolic succession (Peter) to the universal episcopate. It counters division, evoking peace and reconciliation amid historical persecutions, much as Agnes triumphed over pagan threats to her purity.
The rite's placement on Agnes' feast integrates it into the liturgical year, near the octave echoes of ancient commemorations (de passione on January 21, possibly de nativitate on 28). It exemplifies "liturgical symbolism," where symbols bear sacramental specificity, linking theological truths to worship. Indirectly, it invites Marian intercession, as modern papal blessings entrust such traditions to the Virgin Mary, Queen of Peace.
In summary, the St. Agnes lamb-blessing tradition richly weaves personal holiness (Agnes' purity), Christology (Lamb of God), and ecclesiology (pallium's unity), inviting the faithful to contemplate how everyday symbols unveil eternal truths. Rooted in Scripture, hagiography, and papal practice, it calls bishops—and all believers—to shepherd with sacrificial love, fostering communion in the one flock under the one Shepherd.
