US cardinals’ leadership in the United States most clearly reflects Catholic ecclesiology when it is understood as hierarchical communion oriented to service, expressed through episcopal collegiality (with and under the Bishop of Rome), and lived through synodal participation of the whole People of God—culminating in concrete mission (especially charity and the Church’s liturgical/spiritual life).1 2

1) Ecclesiology of communion: leadership as participation in the Church’s “hierarchical communion”

Catholic ecclesiology does not treat leadership as mere “administration” or personal influence; it is rooted in communion. In Pastores gregis, Saint John Paul II describes episcopal ministry as exercised in hierarchical communion and insists that a bishop is “never alone” because he is united both to God through the Successor of Peter and to the other bishops.1 That same communion logic illuminates why US cardinals—who are typically bishops and thus share episcopal responsibility—lead not simply “as individuals,” but as members of a communion that reaches from a local church to the universal Church.1 2

This is also aligned with the way official Catholic theological accounts relate collegiality to synodality: collegiality is the specific theological form in which synodality is “made real” through bishops’ ministry within communion.2

2) Episcopally collegial leadership: working “with Peter” and “under Peter”

A key way US cardinals’ leadership reflects ecclesiology is through episcopal collegiality—that is, bishops acting in communion with the pope and with one another. Saint John Paul II notes that the “spirit of collegiality” exists among bishops continually, though it is expressed in particular ways through canonical forms (e.g., synods, episcopal conferences, Roman Curia, and related processes).1

The Dicastery for Promoting Christian Unity further clarifies how Vatican II’s vision frames the relation between pope and bishops: the bishop of Rome is “head of the college of bishops,” and the Church’s teaching of collegiality requires that authority be understood “in its collegial context.”3 In this view, universal synodality is concretely expressed when bishops act “cum Petro et sub Petro” (with Peter and under Peter).3

So, when US cardinals take leadership roles that emphasize consultation, collaboration, and shared pastoral purpose (rather than isolated decision-making), they concretely mirror this collegial ecclesiology.1 3

3) Synodality as participation: leadership listens, but also teaches and shepherds

Catholic ecclesiology also guards against two opposite distortions:

• reducing the Church to a pure democracy of equal voices without real pastoral authority, or
• reducing it to a purely monarchical structure in which bishops and the faithful have little genuine participation.

The International Theological Commission explains that synodality refers to the involvement and participation of the whole People of God, while collegiality defines the theological significance and form of bishops’ ministry in communion with the Bishop of Rome.2 It also states that “an authentic manifestation of synodality” entails the exercise of collegial episcopal ministry.2

A scholarly theological synthesis further underscores the point in a distinctly Trinitarian way: hierarchy in the Church is “an ecclesiology of service,” and bishops and popes must listen—but cannot abandon their mandate “to teach and to shepherd” without acting in an “anti-Trinitarian fashion.”4

Applied to US cardinals: their leadership roles reflect Catholic ecclesiology when they are characterized by real listening and discernment (synodality) that remain ordered to pastoral teaching, governance, and unity (collegiality and communion).4 2

4) Mission and charity: leadership should embody the Church’s purpose, not only its internal governance

Ecclesiology is not only structural; it is also mission-oriented. The Jubilee-centered message from Pope Leo XIV to Catholic Charities USA describes diocesan Catholic Charities agencies as “agents of hope,” carrying out works of mercy (food, shelter, medical care, legal assistance) and making God’s “style” of closeness, compassion, and tenderness concrete for vulnerable people.5

Notably, in that message the pope expresses gratitude for “collaboration with the Church,” explicitly referencing Cardinal Cupich’s communication about contributions in Chicago (including support for seminarians and service to migrants/refugees).^{^2} The underlying ecclesiology is that the Church’s hierarchy and pastoral leadership are oriented toward the poor as part of the Church’s identity and credibility in the world.5

This matches the broader ecclesiological logic in Pope Leo XIV’s message for a peace-focused gathering: he links “faith, hope and charity” to “cultural conversion,” and describes peace as a practical path of daily gestures rooted in listening and action, not utopian abstraction.6

5) The “eucharistic dimension” of ecclesiology: leadership shaped by how the Church worships and lives

One subtle but important dimension: Catholic ecclesiology is often described as having an explicitly eucharistic character. The Handbook for Liturgical Studies argues that eucharistic ecclesiology recovers the “eucharistic dimension of ecclesiology,” without excluding baptismal or communion ecclesiology.7 It further explains how this supports the enactment of liturgical laws and thus implies that ecclesial authority is not arbitrary—it serves the Church’s worship and therefore the Church’s way of living together.7

The handbook characterizes “liturgical ecclesiology” as emphasizing not only the Church’s cultic activity but also the Church as a body of disciples who “enflesh Jesus’ vision of a new human community based upon justice, mercy, and compassion.”8 In other words: leadership that safeguards liturgy, unity, and moral credibility reflects ecclesiology by ensuring that worship shapes concrete charity and communal life.8

Conclusion

US cardinals’ leadership roles reflect Catholic ecclesiology most faithfully when they are understood as:

• communion-based (never isolated from the pope and the bishops),1
• collegial (authority exercised “cum Petro et sub Petro” in a collegial context),3
• synodal (listening and participation of the People of God without dissolving teaching and shepherding),2 4
• missionary in charity (leadership expressed in concrete mercy for the vulnerable),5
• and liturgically integrated (worship and Church life mutually inform a “new way of living together”).8
