The Legacy of Carthage in the Thought and Witness of the Church and the Episcopal Office

September 19, 2026

Having just visited Tunis, which is the site of the Ancient Carthage, I could not but be mindful of the rich Christian history associated with that city long after the time of Hannibal and the great contest the city attempted with the might of Rome. That history embraced figures of immense impact on the later evolution and spread of Christianity including not only St. Augustine, but also St. Cyprian after whom the new theological center there is named. (And below you see something of the moment for which I was present as the foundation was laid.)

Cyprian served as the bishop of Carthage from 248 until his martyrdom in 258. During this time he guided the still nascent North African church through persecution, schism, and considerable doctrinal and sacramental controversy. His most influential work, De unitate ecclesiae (On the Unity of the Catholic Church), was written to counter the errors of the Novatian schism and is of great interest for the way it articulates a vision of the church as one, visible, and episcopally structured community, or to quite his famously succinct line: “He no longer has God for his Father, who does not have the Church for his mother.”

What this reflected was his high view of the role of the church community in shaping and guarding the faith. It was then as part of this outlook that he held his famously high view of the episcopate — which he saw as one large feature of the church both across space and through time (in a manner of speaking).

In other words, he saw the role of the episcopate as one office shared by many bishops, each possessing authority in his own see but exercising that function also jointly, as part of the role of guaranteeing the church’s unity. A view captured by another of his great phrases, “Ecclesia in Episcopo, Episcopus in Ecclesia”: in other words, the church is in the bishop and the bishop in the church. This entails that unity should be embodied by each bishop — thus recalling that they are (as it was later expressed) called in each case to be a “focus of unity.” As such, bishops are not called to act on private opinions or to step outside the common mind of the wider church on the one hand, while on the other hand unity is found by the faithful — and concretely expressed — through communion with legitimate bishops.

At its strongest, this view of the role of the church came to expression in the famous phrase “Extra ecclesiam nulla salus”: “outside the church there is no salvation,” but there are two points to remember about this expression. First, it was originally framed against schismatics and heretics who break ecclesial communion by failing to submit to the mind of the Church as a whole, and secondly, that this was not a slogan for appropriation by one part of the church to be hurled aggressively at others, rather it reflects the importance of those truths held by all at all times everywhere as Vincentian canon later expressed the point. Thus did Cyprian’s ecclesiology place the concept of the episcopal college of all bishops in the Church of God at the center of the Church universal in which resides the true Catholicity of the Church.¹

This is something that ultimately transcends even the church of the West and includes the Eastern churches also. It is, in this sense, that the principle can serve most authentically as the guarantor of purity in teaching, and sanctifying power within the Church, even when it has proved hard over the centuries to live out the unity to which it also calls all who would seek to belong to the one true Church — which is not a matter of this or that denomination — but ultimately the Church of God.

Cyprian’s thought shaped subsequent debates on many issues that included penance and reconciliation, and how the church should treat the lapsi  (those who apostacized under persecution) and other grave sinners. Baptism and schism: in respect of debates about whether baptism administered outside the visible communion of the church is valid (a controversy that pitted Cyprian and some Eastern bishops against Stephen of Rome for example). Ecclesial “visibility,” which is to say the identification of the spiritual and visible church (the church invisible and visible) terrain, later given a more nuanced expression by St. Augustine but which was fundamentally Cyprian’s in first shape. This legacy of Cyprian was later reflected as his authority came to be invoked at the Council of Ephesus (431) and the way in which he headed later lists of orthodox Fathers in the Decretum Gelasianum.

It is important to notice also that Anglicans have long appealed to Cyprian as a patristic warrant for episcopal governance and conciliarity, as against a hegemonic monarchy by one Patriarch, and this perspective is coming into renewed currency with the current stress on Synodality within the Roman Church, within the Western tradition, while it has long informed the ecclesiology of the Orthodox and Oriental churches.

The model offered by St. Cyprian, of a unified episcopate with each bishop sovereign in his diocese yet nonetheless bound to his colleagues in maintaining the one church, has always resonates strongly with Anglican self-understanding. Both Orthodox and Anglican apologists have used Cyprian to argue for a “non-papal catholicity,” presenting him as a third-century episcopalian whose ecclesiology does not require or even conceive of a papal monarchy.

Again, Anglican ecclesiology has often echoed Cyprian’s emphasis on visible unity expressed through episcopal communion, synodical consultation, and shared faith and practice. All of this has made Cyprian a natural reference point in Anglican–Orthodox and Anglican–Roman dialogues about what constitutes the church’s visible unity.

Within Anglicanism, Cyprian’s dictum is often invoked: To underscore the seriousness of schism and the duty to preserve visible unity.

To argue that salvation is ecclesially mediated—that grace is ordinarily received within the life of the one, holy, catholic, and apostolic church—while leaving room for God’s mercy beyond visible boundaries.

To support a high-church ecclesiology that takes episcopal succession, sacraments, and conciliar unity as constitutive of the church’s identity.

Thus, Cyprian serves both as a warning against casual division and as a resource for articulating a robust but nuanced catholicity compatible with Anglican comprehensiveness.

This line of reasoning was further developed in St. Augustine.

St. Augustine inherited St Cyprian’s high view of the church’s unity and episcopal authority but refined it in the light of the Donatist conflict, where rigorist separatists claimed that only the “pure” church (their own) could validly administer sacraments.

Augustine’s response led to several distinctive perspectives which could be summarized thus:

Mixed body (corpus permixtum): The visible church on earth contains both saints and sinners, wheat and tares; it is not coextensive with the elect.

Visible and invisible dimensions: Augustine speaks of the church as both a visible, institutional reality (with hierarchy, sacraments, and creed) and an invisible reality—the communion of the predestined elect known only to God.

Validity vs fruitfulness of sacraments: Against the Donatists (and implicitly revising Cyprian), Augustine argues that schismatics can administer valid baptism (because the sacrament belongs to Christ, not the minister), but its saving benefit (munus beatae vitae) is received only within the charity and unity of the catholic church.

Unity in the Spirit: Whereas Cyprian locates unity chiefly in the visible harmony of bishops, Augustine locates the church’s deepest unity in the Holy Spirit, who binds the elect in charity; visible communion is necessary but not identical with this inner unity.

Augustine thus “magnifies and modifies” Cyprian’s thesis: he keeps extra ecclesiam nulla salus but reinterprets it so that one can be sacramentally marked outside visible communion yet lack the saving fruit of the sacraments until reconciled to the church’s charity.

St. Augustine’s evolution of thought then in turn allowed later articulations (again in summary here) to:

Maintain St. Cyprians view of catholicity (one visible church with sacraments and apostolic ministry) while acknowledging that not all members are saved and that grace can be at work beyond strict visible boundaries.

Develop a sacramental theology in which the efficacy of rites depends ultimately on Christ and the Spirit, not on the personal holiness of ministers—a direct anti-Donatist legacy that also softens Cyprian’s rigorism about schismatic sacraments.

Provide resources for later distinctions between the visible/invisible church that Protestant reformers would radicalize, even though Augustine himself still identified the catholic church as the true church and does not separate the two realities as later Reformers sought to do.

In short, Cyprian offers a clear, “boundary-driven” ecclesiology centered on visible unity and episcopal communion; while St. Augustine preserves that core but adds depth and nuance by distinguishing the church’s empirical reality from its hidden, elect reality and by separating sacramental validity from saving fruitfulness.

But it is still worth reiterating the importance of the role of the episcopate in in Cyprian’s ecclesiology. For him, the bishop is never simply an administrator or teacher but always the theological hinge of the church’s unity, holiness, and sacramental life. His famous formula—“the bishop is in the church, and the church in the bishop” (episcopum in ecclesia esse et ecclesiam in episcopo)—encapsulates a vision in which communion with the legitimate bishop is the concrete criterion for belonging to the one, saving church. To conclude in more summary form:

1. The authentic bishop serves as locus and guarantor of unity

Cyprian’s treatise De unitate ecclesiae argues that the church is fundamentally one, and that this unity is visibly embodied in the episcopal college:

“The episcopate is one, each part of which is held by each one for the whole.”

The bishop is the point at which the local community is united to the universal church; schism arises when people “contemn the bishop who is one and rules over the Church.”

Hence his aphorism: “You ought to know that the bishop is in the church, and the church in the bishop; and if anyone is not with the bishop, he is not in the church.”

In this perspecitive unity with the bishop is identical with unity with the church, and thereby with Christ.

2. Sacramental and sacerdotal role

Cyprian endows the bishop with a strongly sacerdotal character:

The bishop is a “spiritual priest, a consecrated “sacrificer,” and the vicar of Christ in sacred affairs,” through whom “the life of Christ [is] transmitted to the Church.”

The bishop presides over the Eucharist and other rites as the chief minister of his local church; the presbyterate shares in his functions as “co-presbyters,”.

Because the Spirit works through the divinely ordered episcopate, sacraments administered outside communion with the bishop—by schismatics or heretics—are, for Cyprian, not truly the church’s sacraments and do not convey salvation.

Thus the bishop is the divinely appointed conduit of grace and the guardian of the church’s sanctifying power.

3. Apostolic succession and the “one episcopate”

Cyprian understands the episcopate as the continuation of the apostolate:

“In his scheme the apostolate was perpetuated in the episcopate.”

The episcopate is one office shared by many bishops; each bishop holds the whole episcopate “for the whole,” so that there is no “bishop of bishops” above them.

This yields a collegial and conciliar model: bishops are equal in dignity, bound together in mutual concord, and jointly responsible for the unity of the universal church.

Cyprian’s own practice—regular African synods and consultation with fellow bishops—embodies this vision of a unified but non-monarchical episcopate.

4. Governance, discipline, and synodality

While the bishop is the centre of authority, Cyprian does not picture a bishop as an autocrat:

The bishop is the divinely appointed praepositus (leader) on whom “the management of Church affairs rested,” yet he is to act in consultation with clergy and faithful, who together constitute the ecclesia.

Cyprian stresses that bishops are rightly chosen in the presence of the people, with their “suffrage and testimony”; the laity retain the power to choose worthy candidates and even to depose unworthy bishops.

Discipline and doctrinal decisions are worked out synodically: “for the sake of discipline and unity, the bishop cooperates with fellow bishops.”

Thus, the bishop’s authority is real and divinely grounded, but exercised within a communal and conciliar framework if it is to be authentic.

5. Soteriological significance: “no church without the bishop”

Cyprian’s high view of the bishop has direct soteriological consequences:

“There is no Church” without the bishop; union with the church—and thus with Christ—is effected “only by obedient dependence on the bishop.”

Those who separate from the bishop separate from the church and therefore from the promises of salvation: “he who forsakes the Church of Christ [i.e., the episcopally united community] cannot attain to the rewards of Christ.”

This undergirds his insistence that schismatics and heretics stand outside the saving church, since they have broken communion with the episcopal order (but we have to remember the church is not reduced to this or that denomination).

In short, for Cyprian the bishop is the visible criterion of catholicity and the necessary channel of salvation which role is however always exercised within the wider role of the ecclesia it is never as it were some “private possession” and is only authentic when exercised within that broader understanding and reality of the wider Church of God.
