Pope Saint Anacletus: History, Apostolic Succession, and Legacy of the Third Pope

Pope Saint Anacletus (reigned c. AD 76–88), venerated in the Sacred Liturgy as Saint Cletus, served as the third Bishop of Rome and the second successor to Saint Peter the Apostle. Governing the Roman Church during the volatile sub-apostolic period under the Flavian emperors, Anacletus preserved the apostolic Deposit of Faith (depositum fidei), organized Rome’s earliest ecclesiastical structures, and solidified the continuity of the Petrine primacy instituted directly by Jesus Christ.

Historical Identity: Resolving the “Cletus vs. Anacletus” Question

Very few administrative records from the first-century underground Church survived imperial crackdowns, leading to early historical debates regarding whether “Cletus” and “Anacletus” were two separate pontiffs. The fourth-century Liberian Catalogue listed them as distinct individuals; however, the earliest and most authoritative patristic testimonies demonstrate that both names refer to the same man.

St. Irenaeus of Lyons (c. AD 130–202), writing in Adversus Haereses (Against Heresies, 3.3.3), provides the oldest uninterrupted succession list of the Bishops of Rome:

“The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate… To him succeeded Anacletus; and after him, in the third place from the apostles, Clement was allotted the bishopric.”

This succession line is confirmed by the fourth-century Church historian Eusebius of Caesarea in his Historia Ecclesiastica (3.13) and is enshrined immutably within the Roman Canon of the Mass. “Cletus” represents a shortened, affectionate Greek hypocorism of “Anacletus” (meaning “blameless” or “invoked”).

Tradition indicates that Anacletus was of Greek lineage, born in Athens, yet resided in Rome where he encountered the Gospel directly through the preaching of Saints Peter and Paul.

Apostolic Succession and the Divine Institution of the Papacy

Catholic dogma affirms that the primacy of the Roman Pontiff is not a human administrative convention or a sociological development of the sub-apostolic era. Rather, the Petrine office was instituted immediately and directly by Christ Jesus as a perpetual principle of visible unity (First Vatican Council, Pastor Aeternus, cap. 2; Denzinger-Hünermann 3056–3058).

As the Catechism of the Catholic Church teaches, Christ established the Apostles and their successors to shepherd His flock until the end of time (CCC 880). The Pope, as the Bishop of Rome and successor to Peter, is “the perpetual and visible source and foundation of the unity both of the bishops and of the whole company of the faithful” (CCC 882).

St. Thomas Aquinas highlights this ontological necessity for the Church in his Summa Contra Gentiles (Book IV, Chapter 76). The Angelic Doctor asserts that because Christ intended His Church to remain unified across all centuries, He necessarily endowed Peter with a perpetual office of supreme governance that would pass to his successors.

Anacletus did not receive this authority through secular politics or community consensus. Conformed to Christ through the Sacrament of Holy Orders by the apostolic laying on of hands (impositio manuum; cf. 1 Tim 4:14; 2 Tim 1:6; CCC 1562, 1573), Anacletus assumed the Chair of Unity to safeguard the Deposit of Faith against nascent gnostic distortions.

Ecclesiastical Governance and Roman Church Organization

Despite living under the constant threat of Roman surveillance and judicial execution, Pope Saint Anacletus instituted structural measures that defined the administrative and liturgical life of the Roman Diocese.

Division of Rome into Parish Titles (Tituli)

The Liber Pontificalis attributes to Pope Anacletus the formal division of the City of Rome into twenty-five distinct pastoral districts, known as tituli.

• Sacramental Care: These proto-parishes were assigned to designated presbyters to ensure the consistent distribution of the Sacraments to the faithful.
• Ecclesiastical Order: This structural division prevented sacramental fragmentation as the Roman Christian population expanded across various social strata.
• Clerical Hierarchy: It established a clear chain of pastoral accountability between the Bishop of Rome and his urban presbyterate.

Canonical Norms for Episcopal Consecrations

Ancient canonical collections, including the Pseudo-Isidorian Decretals and early synodal commentaries, credit Saint Anacletus with formalizing the rule that a bishop must be consecrated by no fewer than three bishops.

This ancient apostolic rule, designed to safeguard sacramental validity and communion, remains codified in the contemporary Code of Canon Law (CIC, Canon 1014). He also regulated clerical vestments and insisted that public ordinations occur with solemn communal fasting and prayer.

Construction of the Cella Memoriae at Saint Peter’s Tomb

Among his most celebrated material achievements was the construction of a burial monument—the Cella Memoriae (or “Trophy of Gaius”)—over the resting place of Saint Peter on the Vatican Hill.

Located in the pagan necropolis along the Via Cornelia where Peter was buried following his crucifixion under Nero, this modest stone shrine served as a central locus of underground Christian devotion. Excavations beneath Saint Peter’s Basilica conducted under Pope Pius XII in the 1940s verified that Constantine’s monumental fourth-century basilica was built directly over this sub-apostolic memorial erected by Anacletus.

Eucharistic Centrality and Sub-Apostolic Spirituality

The spirituality of Pope Saint Anacletus was entirely Eucharistic, ascetic, and sacrificial. In the sub-apostolic era, the Holy Sacrifice of the Mass was celebrated in private homes (domus ecclesiae) and catacombs under the veil of absolute secrecy.

For Anacletus and his flock, the Eucharist was not a mere symbolic fellowship meal; it was the actual re-presentation of the Sacrifice of Calvary and the substantial Real Presence of the Body, Blood, Soul, and Divinity of Jesus Christ (CCC 1364, 1374).

The early Roman Christians derived the supernatural fortitude required to face the Colosseum and the Roman executioners directly from their reception of Holy Communion. Anacletus mandated that all faithful present at the Eucharistic assembly participate in the reception of the Sacrament unless canonically excluded, emphasizing that interior communion with Christ demands exterior unity with His visible Church.

Martyrdom and the Witness of the Roman Canon

The reign of Pope Saint Anacletus concluded around AD 88, during the reign of Emperor Domitian, a period marked by renewed imperial paranoia and anti-Christian hostility.

Ancient tradition records that Anacletus crowned his twelve-year pontificate with glorious martyrdom, shedding his blood for Christ. The Catechism reminds us that “martyrdom is the supreme witness given to the truth of the faith: it means bearing witness even unto death” (CCC 2473).

Pope Anacletus was buried on the Vatican Hill adjacent to the relics of Saint Peter, joining his predecessor Saint Linus in the sacred soil that formed the bedrock of Christian Rome.

The Church’s supreme liturgical monument to his sanctity is found in the Communicantes prayer of the Roman Canon (Eucharistic Prayer I). In every Holy Mass where this venerable prayer is spoken, the priest proclaims:

“In communion with those whose memory we venerate, especially the glorious ever-Virgin Mary, Mother of our God and Lord, Jesus Christ, and blessed Joseph, her Spouse, your blessed Apostles and Martyrs, Peter and Paul, Andrew… Linus, Cletus, Clement, Sixtus, Cornelius…”

Through this daily liturgical proclamation (lex orandi, lex credendi), the Catholic Church perpetually honors the third Pope who preserved the apostolic fire during the darkest hours of imperial oppression.

Enduring Lessons for Modern Catholics

The sub-apostolic witness of Pope Saint Anacletus offers urgent, practical wisdom for contemporary believers navigating hostile secular cultures:

• Uncompromising Fidelity to Apostolic Tradition: Anacletus added nothing novel to the Gospel; he guarded the Deposit of Faith (depositum fidei) intact (2 Tim 1:14). Catholics are called to anchor their intellects in the immutable dogmas of Sacred Tradition rather than shifting cultural trends.
• Reverence for the Eucharistic Sacrifice: In times of cultural isolation, the Holy Mass remains the divine fountain of supernatural grace and fortitude (CCC 1324).
• Sacrificial Submission to Church Unity: True reform and spiritual stability are never found in schism or rebellion, but in humble, prayerful communion with the hierarchical Church established by Christ on the rock of Peter (CCC 816).
