Understanding the difference between Churches and rites helps avoid common misunderstandings in liturgical discussions.
Nearly every article or social media post about current restrictions on the Latin Mass eventually produces a familiar refrain: “If this can happen to the TLM, it could just as easily happen to the East.”
Such statements rest on a basic misunderstanding of what the Church means by “Church” and “rite.” Clarifying two fundamental points of Catholic ecclesiology will help ensure that serious discussion can proceed on solid ground.
From its beginnings, the Church has never existed as a single, undifferentiated monolith. Scripture and Tradition present a Church that grows as a communion of local Churches. Christ’s commission to Peter (Matthew 16), the missionary activity of the apostles, and the early organization of Christian communities all point in this direction.
By the time of the First Ecumenical Council of Nicaea (325), this reality was already reflected juridically. Nicaea’s canons recognize the established jurisdictions of Rome, Alexandria and Antioch, with Jerusalem receiving special honor. The First Council of Constantinople (381) placed the bishop of Constantinople second in honor after Rome, and Chalcedon (451) effectively ratified the five principal patriarchal sees: Rome, Constantinople, Alexandria, Antioch and Jerusalem.
From the earliest centuries, then, the Catholic Church has understood herself as a communion of Churches, united with — but not absorbed into — the primatial see of Rome.
That same structure remains today. The Catholic Church is composed of the Latin Church and 23 Eastern Catholic Churches sui iuris. This brings us to the first key distinction. According to the Code of Canons of the Eastern Churches (CCEO 27), a Church sui iuris is “a community of the Christian faithful, which is joined together by a hierarchy according to the norm of law and which is expressly or tacitly recognized as sui iuris by the supreme authority of the Church.”
The term sui iuris — “of one’s own right” — signals real ecclesial autonomy. Each such Church possesses its own hierarchy, internal law and structures of governance, all exercised in full communion with Rome. Autonomy and communion are not opposites here; they are complementary principles rooted in apostolic tradition and sustained in charity.
Within these Churches exist various liturgical rites. Broadly speaking, the Eastern Catholic Churches celebrate according to the Constantinopolitan (Byzantine), Alexandrian, Antiochene, Armenian or Chaldean rites, each of which branches further into liturgical families and specific anaphorae (eucharistic prayers), such as the Anaphora of St. John Chrysostom (Constantinopolitan) or that of Addai and Mari (Chaldean/East Syriac). Canon 28 of the CCEO defines a rite as the “liturgical, theological, spiritual and disciplinary heritage” of a people, shaped by history and culture and expressed by a Church sui iuris in its manner of living the faith.
History shows that individual rites or liturgical usages have at times been suppressed or displaced, often through political upheaval or conquest. In the Latin Church, the most prominent example comes from the pontificate of Pope St. Pius V. Following the Council of Trent, Pius V promulgated the Roman Missal and suppressed a number of relatively recent or unstable local Latin uses that lacked clear antiquity or consistency. Far from being an act of liturgical vandalism, this was a measured attempt to establish a normative form where no venerable alternative existed — while explicitly preserving ancient rites such as the Ambrosian and Mozarabic.
Where does this leave current debates about the Traditional Latin Mass? It helps us see that appeals to the Eastern Churches are largely misplaced. Eastern Catholic Churches are not defined by a single rite, nor are they mere liturgical preferences granted at Rome’s discretion. They are Churches in the full ecclesiological sense, exercising real authority over their rites within the bonds of communion. Suppressing an entire Eastern Church would be tantamount to provoking schism and is not a realistic possibility.
As for forbidding an Eastern anaphora, while theoretically conceivable, it has never occurred. On the contrary, Rome has repeatedly acted as a guarantor of Eastern liturgical patrimony. The 2001 decision affirming the validity of the Anaphora of Addai and Mari — despite the absence of an explicit institution narrative — is a striking example of Rome serving the East by protecting, rather than constraining, its tradition.
A clearer understanding of these distinctions does not weaken concern for the TLM; it strengthens the conversation. The TLM is an extraordinary form of the Roman Rite and therefore falls under the direct jurisdiction of the Latin Church. Eastern Catholics are not simply “Latin Catholics with a different Mass,” but members of distinct Churches bearing their own apostolic inheritances. Invoking the East as a rhetorical shield in debates over Latin liturgical policy may score sympathy points, but it obscures more than it illuminates.
Many Catholics understandably desire to preserve the Traditional Latin Mass. I have attended it myself and count many devoted TLM Catholics among my friends. But serious questions about liturgical reform deserve serious arguments. The Eastern Churches can contribute to these conversations as witnesses to continuity, diversity and communion, provided their identity is rightly understood. Precision, not polemic, is what ultimately serves both truth and unity in the Church.
