Catholicism: An introduction to Its Branches, Sects, and Denominations

A Pilgrim’s Guide to the Catholic Family: An Introduction to Its Branches and Divisions

We begin not with lists of divisions, but with a moment of quiet reflection. Imagine our Christian family as a vast, ancient tree, with one trunk rooted firmly in Christ, but with branches that have grown in many directions over two millennia. Some branches are strong and vibrant, reaching toward the heavens in beautiful and diverse ways. Some are gnarled and weathered by history, and some, tragically, have broken away from the life-giving trunk. This article is a journey to understand this family tree, to celebrate its diversity, and to pray for its healing. It is written with a shepherd’s heart, hoping to bring clarity and peace to a topic that can often cause confusion and pain. Our guide will be the Church’s own self-understanding, a spirit of love, and an unshakeable hope in the Lord’s prayer “that they may all be one” (John 17:21).

What Does the Catholic Church Believe About Its Own Unity?

The heart of the Catholic Church’s identity is found in the Nicene Creed, where we profess our belief in a Church that is “one, holy, catholic, and apostolic”.¹ These are not just descriptive words; they are gifts from Christ, poured into the Church by the Holy Spirit. The Catechism of the Catholic Church teaches that these four marks are “inseparably linked with each other” and point to the essential features of the Church and her mission.¹ They are the very essence of who she is.

The Divine Source of Unity

The Church’s unity is not something she achieves on her own, through committees or human effort. Its ultimate source is the perfect, loving unity of the Holy Trinity: “the unity, in the Trinity of Persons, of one God, the Father and the Son in the Holy Spirit”.² It is Christ, the “prince of peace,” who reconciled all people to God, founding one people and one body on earth.² The Holy Spirit, dwelling in the hearts of the faithful, is the “soul” of this Mystical Body, binding all believers together in a “wonderful communion”.² This unity, therefore, is a divine gift, as powerful and mysterious as the life of God Himself.

A Unity Wounded by Sin

Although we believe the Church’s unity is an indestructible gift from God, its visible expression has been wounded by human sin throughout history. This is a source of powerful sorrow. From the earliest days, St. Paul had to urge the Christians in Ephesus to “maintain the unity of the Spirit in the bond of peace” (Ephesians 4:3).² Over the centuries, these wounds became deeper, leading to “much more serious dissensions” where “large communities became separated from full communion with the Catholic Church”.²

This presents a sacred paradox. The Church is divinely instituted and professes an unbreakable unity, yet it acknowledges a painful history of ruptures that wound the Body of Christ. This is not a contradiction but a reflection of the Church’s very nature: she is at once holy in her divine origin, yet composed of sinful members on their earthly pilgrimage. Her unity is a gift that is already possessed in its essence, but its full, visible realization is not yet complete. This understanding prevents us from falling into either a prideful triumphalism that ignores the real pain of division, or a hopeless despair that believes our divisions have destroyed Christ’s Church.

In a spirit of humility, the Catechism acknowledges that for these historic separations, “often enough, men of both sides were to blame”.² Yet, even in this wounded state, the Church believes that all who are baptized in Christ are joined to her in a real, though imperfect, communion.⁶ They are our brothers and sisters in the Lord.

The Unceasing Call to Reconciliation

Because her unity is a gift from Christ, the Church never stops praying and working for the reconciliation of all Christians. This deep desire is itself a “gift of Christ and a call of the Holy Spirit”.² It is a sacred duty that requires a constant renewal of the Church in fidelity to her vocation, a powerful “conversion of heart” from all her members, and a loving, patient dialogue with our separated brothers and sisters.²

How Can We Understand the Terms: “Rites,” “Churches,” and “Denominations”?

To navigate our family tree with care and understanding, we need the right words. Often, terms like “rite,” “church,” and “denomination” are used interchangeably, but in the Catholic context, they have very specific and beautiful meanings. Understanding them helps us see the breathtaking diversity that exists within Catholic unity. Exploring the distinctions among various Christian practices can deepen our appreciation for each tradition. For instance, examining presbyterian and catholic beliefs compared reveals both shared values and unique perspectives on authority, sacraments, and community. This enriched understanding encourages dialogue and fosters a spirit of unity amidst our differences.

The Catholic Church is a Communion of Churches

It may be a surprise to many to learn that the Catholic Church is not a single, monolithic organization. It is a communion of 24 distinct, self-governing Churches, all united in faith and in communion with the Pope as the successor of St. Peter.⁸ These are called

sui iuris Churches, a Latin term meaning “of its own law”.⁸ This means that while they share the same essential faith and sacraments, they have their own distinct ways of living out that faith.

The Church that most people in the Western world think of as “the Catholic Church” is the largest of these 24 Churches: the Latin Church. It is governed by the Code of Canon Law and its primary liturgical tradition is the Roman Rite.¹² The other 23 Churches are known as the Eastern Catholic Churches.

What is a “Rite”?

A rite is much more than just the way Mass is celebrated. It is a whole “ecclesiastical tradition” that includes a unique liturgy, theology, spirituality, and canonical discipline.¹⁴ It is the unique cultural and historical expression of the one Catholic faith.¹⁵ Think of it as a particular family’s way of celebrating a holiday; the reason for the celebration is the same for all, but the specific songs, foods, and customs are unique to that family, expressing their shared joy in their own beautiful way.

There are six major parent rites in the Catholic Church: Latin, Byzantine, Alexandrian, Syriac, Armenian, and Chaldean.⁹ Several different sui iuris Churches may share the same rite. For example, the Ukrainian Catholic the Melkite Greek Catholic and the Romanian Greek Catholic Church are all distinct, self-governing Churches, but they all celebrate the liturgy according to the ancient and beautiful Byzantine Rite.⁸

This vast web of traditions reveals a powerful truth about the Church: its unity is symphonic, not monolithic. It does not demand that all believers conform to a single cultural expression. The Church’s true catholicity—its universality—is shown precisely in her ability to embrace and sanctify diverse cultural expressions of the one faith.¹⁹ She does not seek to destroy cultures but to baptize them, allowing the one faith to be expressed in a beautiful variety of ways. This stands in stark contrast to historical attempts by some other bodies to impose a rigid uniformity on all their members.¹⁶

Who Are the Eastern Catholic Churches?

Pope St. John Paul II famously said that for the Church to be whole, she must breathe with “both lungs”—East and West. The 23 Eastern Catholic Churches are this vital Eastern lung, a living testament to the ancient and diverse roots of our faith.⁸ They are ancient communities, many tracing their origins back to the Apostles themselves, who at various points in history restored the full communion with the Pope of Rome that had been broken by tragic schisms.²¹

Fully Catholic, Fully Eastern

It is essential to understand that these Churches are not “Roman Catholics who happen to be in the East.” They are fully and authentically Eastern in their traditions, theology, and law, and at the same time, fully and authentically Catholic.⁸ They have their own hierarchies, their own patriarchs and major archbishops, their own canon law (the

Code of Canons of the Eastern Churches, or CCEO), and their own rich spiritual patrimony, which they are called to cherish and preserve.¹⁰ A member of the Latin Church fulfills their Sunday obligation by attending the Divine Liturgy at an Eastern Catholic parish, and may receive Holy Communion there, because we are all members of the same Catholic communion.⁹

The existence of these Churches is not just a historical curiosity; it is a living model for the ultimate goal of Christian unity, especially with our Orthodox brothers and sisters. These Churches came into being through “reunions” where communities restored communion with Rome while retaining their own liturgical, canonical, and spiritual traditions.²¹ This historical process serves as a concrete, living proof that the model for reunion is not absorption into the Latin Rite, but unity in faith and communion while preserving legitimate and beautiful diversity. The Eastern Catholic Churches are a prophetic sign, a “bridge” between East and West, and a message of immense hope that the prayer of Christ for unity can be realized.

A Few Family Portraits

To appreciate this beautiful diversity, let us meet just a few of these sister Churches:

• The Maronite Church: This ancient with its heartland in the mountains of Lebanon, holds a unique place in the Catholic family. It asserts that it never broke communion with Rome, only that communication was cut off for centuries by political realities.²² Tracing its spiritual heritage to the 4th-century hermit St. Maron, it uses the West Syriac Rite and has played a central, defining role in the history and culture of Lebanon.²⁴
• The Ukrainian Greek Catholic Church: The largest of the Eastern Catholic Churches, with over 5.⁵ million faithful, the UGCC is a story of heroic faith.²⁸ Born from the Union of Brest in 1596, its history has been marked by brutal persecution, especially under the Soviet Union, which tried to liquidate the Church entirely.²⁹ Its re-emergence from the underground in 1989 was a powerful moment of resurrection for the entire Catholic communion. They follow the beautiful Byzantine Rite.²⁹
• The Syro-Malabar Church: This major Church in India traces its origins to the preaching of St. Thomas the Apostle himself, who is said to have arrived in 52 AD.³² It is a vibrant example of a faith that is deeply Indian in its culture, while being Syriac in its liturgy (using the East Syriac Rite) and fully Catholic in its communion.³² With over 4.⁵ million members, it has a growing presence around the world, including a diocese based in Chicago to serve the faithful in the United States.³⁴

What Are Movements Like Opus Dei and the Neocatechumenal Way?

It is a common point of confusion to see groups like Opus Dei or the Neocatechumenal Way as separate “types” or “sects” of Catholicism. They are not. They are spiritual families and itineraries of formation within the Catholic fully approved by the Holy See, and open to all the faithful who feel called to their particular path.¹³ The in her wisdom, recognizes that there is no “one size fits all” spirituality. The Holy Spirit provides different “charisms” and movements to meet the diverse spiritual needs of God’s people.

Opus Dei: Sanctifying Daily Work

Founded by the Spanish priest St. Josemaría Escrivá in 1928, the core message of Opus Dei (Latin for “Work of God”) is the “universal call to holiness”.³⁷ This is the beautiful truth that sanctity is not just for priests and nuns, but for everyone, and it can be achieved through one’s ordinary work and family life.³⁹ Opus Dei is a “personal prelature,” a unique canonical structure with its own bishop who guides the formation of its members, but these members remain faithful of their local dioceses and parishes.³⁷ Its central mission is to help laypeople see their jobs, hobbies, and family duties not as an obstacle to their relationship with God, but as the very path to union with Him.³⁹

The Neocatechumenal Way: A Post-Baptismal Journey

The Neocatechumenal Way began in the slums of Madrid, Spain, in 1964 as a powerful method to re-evangelize those who were baptized but not fully living their faith.³⁶ It is a “post-baptismal catechumenate,” an itinerary of formation that takes place in small communities within a parish.³⁶ Over a period of many years, members journey together, rediscovering the immense riches of their baptism and growing in faith, humility, and love.⁴² The Way is known for producing an abundance of vocations to the priesthood and for sending missionary families all over the world to plant the Church in de-Christianized areas.³⁶

The Catholic Charismatic Renewal: A Current of Grace

This powerful movement, which began at a student retreat in the United States in 1967, is often described as a “current of grace” that has swept through the Church.⁴³ It is not a single, unified organization but a diverse movement that emphasizes a personal and transformative experience of the Holy Spirit, often called the “baptism in the Holy Spirit”.⁴³ This is not a new sacrament, but an awakening of the graces already received in Baptism and Confirmation.⁴⁷ The Renewal encourages the joyful use of spiritual gifts (charisms) like healing, prophecy, and prayer in tongues for the building up of the Church and the glory of God.⁴³ It has been warmly encouraged by recent Popes as a sign of the Spirit’s life-giving action in our time.⁴³

What Is the Society of St. Pius X (SSPX) and Why Is Its Status “Irregular”?

The story of the Society of St. Pius X (SSPX) is one of the most painful internal struggles in the recent history of the Catholic Church. It is a story that should be approached with a gentle heart, recognizing it not as a tale of villains and heroes, but as a tragedy born of deep conviction and powerful fear during a time of great turmoil and confusion in the Church.

Origins in Post-Vatican II Turmoil

The SSPX was founded in 1970 by the French Archbishop Marcel Lefebvre, a respected missionary and churchman.⁴⁹ He and his followers were deeply concerned by the changes they saw in the Church following the Second Vatican Council (1962-65). They believed that some of the Council’s teachings, particularly on religious liberty, ecumenism (the relationship with other Christian denominations), and a concept called collegiality (the relationship between the Pope and the bishops), represented a dangerous break with unchanging Catholic Tradition.⁴⁹ They were also pained by the liturgical reform that produced the new Mass (the

Novus Ordo Missae) and were committed to preserving the traditional Latin Mass (the Tridentine Rite).⁵¹

The 1988 Consecrations and Excommunication

The breaking point came on June 30, 1988. Fearing that true Catholic Tradition would die out without bishops to ordain traditional priests, and after negotiations with the Vatican broke down, Archbishop Lefebvre consecrated four bishops without the permission of Pope John Paul II.⁵⁰ This was a direct and grave violation of canon law, which reserves the appointment of bishops to the Pope alone.⁵⁶ In his apostolic letter

Ecclesia Dei, Pope John Paul II declared that this disobedient act was schismatic in nature and that Archbishop Lefebvre and the four new bishops had incurred an automatic excommunication.⁵²

An “Irregular” Canonical Status

The situation today is complex and delicate. In 2009, Pope Benedict XVI, in a gesture of paternal mercy and with a deep desire to heal this wound, lifted the excommunications from the four bishops, hoping to open a clear path to full reconciliation.⁵⁰ But he clarified that this act of mercy did not solve the underlying doctrinal problems. Therefore, the SSPX remains in an “irregular canonical status”.⁴⁹ This means:

• They are not in formal schism in the same way as, for example, the Eastern Orthodox Churches. The Vatican has stated that “they are within the confines of the Church”.⁵⁹ They have never denied the authority of the Pope; they have only disobeyed it.
• Their priests are validly ordained, and their Masses are valid. But because the Society has no approved legal standing in the their ministry is considered illicit (unlawful).⁵⁶
• In a further act of powerful pastoral care, Pope Francis has granted all SSPX priests the faculty to hear confessions validly and has established a process for local bishops to authorize SSPX weddings. He did this for the spiritual good of the faithful who attend their chapels, so that they would not be deprived of the grace of these sacraments.⁵⁰

This situation reveals the heart of the Church acting not just as a lawgiver, but as a mother. While the SSPX remains in a state of objective disobedience, the Pope recognizes that hundreds of thousands of faithful souls attend their chapels.⁴⁹ To deny them access to valid forgiveness in confession or a valid marriage would be to punish the sheep for the choices of their shepherds. By granting these faculties, the Pope is making a pastoral provision that prioritizes the supreme law of the Church: the salvation of souls. It is a powerful act of mercy that keeps a bridge open for reconciliation, demonstrating that even amid deep disagreements, the Church’s primary concern is the spiritual well-being of every single person.

Why Did the Old Catholic and Polish National Catholic Churches Separate from Rome?

Not all separations from the See of Peter have the same cause. The stories of the Old Catholic and Polish National Catholic Churches show how different historical pressures—one theological and European, the other administrative and American—can lead to a tragic break in communion.

The Old Catholics and Papal Infallibility

The Old Catholic Church emerged from the dissent of a number of Catholics, primarily in Germany, Austria, and Switzerland, who could not in conscience accept the dogma of Papal Infallibility, which was defined at the First Vatican Council in 1870.⁶¹ Led by prominent theologians and historians, they sought to adhere to the faith as they believed it existed

before this definition, hence their chosen name “Old Catholic”.⁶¹ To ensure they had valid sacraments, they sought out and received episcopal consecration from the Jansenist Church of Holland, a small group that had separated from Rome in the 18th century but had preserved a valid line of bishops.⁶³

The Polish National Catholic Church and Parish Rights

The Polish National Catholic Church (PNCC) was born on American soil in 1897, not primarily over a doctrinal dispute, but over issues of governance, culture, and justice.⁶⁵ Polish immigrants, who had sacrificed greatly to build their own churches, felt marginalized and disrespected by a Church hierarchy in the United States that was dominated by Irish and German bishops.⁶⁸ They wanted to own their parish property, have a say in their administration, and ensure their Polish language and traditions were honored.⁶⁷ When their heartfelt pleas were denied, they formed an independent church under the leadership of a charismatic priest, Fr. Franciszek Hodur, who was later consecrated a bishop by the Old Catholics in Europe.⁶⁵

The different origins of these schisms highlight a crucial point. While some divisions arise from high-level theological debate, others can be born from a failure of pastoral sensitivity to the legitimate needs and cultural identity of the faithful on the ground. The story of the PNCC is a sobering lesson for the Church about the importance of inculturation and respecting the rights and heritage of all God’s people.

Pathways of Dialogue

The relationship with these groups is not frozen in time. While the main body of Old Catholic Churches in Europe (the Union of Utrecht) has adopted practices like the ordination of women, which creates a major new obstacle to reunion, the PNCC has not.⁶⁸ This has allowed for a more fruitful and hopeful dialogue between the PNCC and the Roman Catholic Church. This dialogue led to a “limited communion agreement” where, in certain grave circumstances and with proper disposition, their faithful may receive the sacraments of Penance, Eucharist, and Anointing of the Sick from Catholic ministers.⁶⁷ This is a beautiful sign of hope and a step toward healing a painful, century-old wound.

What Do Sedevacantists Believe?

Among those who have separated from the Sedevacantism is the most radical and extreme position. It represents a very small fringe of people who have taken their grievances to a sorrowful conclusion.⁷³ The name itself comes from the Latin phrase

sede vacante, which the Church uses to describe the period when the Chair of Peter is vacant between the death or resignation of one pope and the election of another.⁷³

The Core Belief: The Chair is Empty

Sedevacantists believe that this state of sede vacante has been ongoing for decades. Most hold that there has been no valid Pope since the death of Pope Pius XII in 1958.⁷³ They argue that the Popes who presided over and implemented the Second Vatican Council (St. John XXIII, St. Paul VI, and all their successors) publicly professed heresy and therefore automatically lost their office.⁷³

As a result, they reject the Second Vatican Council and all subsequent papal teaching as completely invalid. They believe the new rites for the Mass and the other sacraments are also invalid, and that the “Conciliar Church” is a new and false religion that has broken away from the true Catholic Church.⁷³ It is vital to understand that this is not a “branch” or “denomination” but a fringe belief held by a very small number of people, estimated to be in the tens of thousands worldwide.⁷³ They are distinct from the SSPX, which recognizes the validity of the recent Popes even while disobeying them.⁷⁹ These beliefs underscore the significant divisions within Christianity, particularly in the context of catholic and protestant differences. While the mainstream Catholic Church embraces the reforms of Vatican II as a means to engage with the modern world, those who reject it view these changes as a departure from authentic tradition. This schism highlights ongoing theological debates that continue to shape Christian identity and practice today. This rejection of the Second Vatican Council is rooted in a desire to preserve what they consider essential catholic beliefs and practices that have been compromised by modernizations. The divide between these groups and mainstream Catholicism illustrates how interpretations of doctrine can vary significantly, leading to distinct communities within the broader Christian landscape. As a result, ongoing discussions about tradition and reform remain pivotal in shaping the future of the faith. This situation also fuels a broader inquiry into the differences in identity and authority within Christianity, often encapsulated in discussions such as ‘roman catholic vs catholic explained.’ The contrasting views regarding Church authority and the interpretation of tradition continue to inform not only theological debates but also the personal faith journeys of many individuals. As these communities evolve, the question of how to reconcile tradition with contemporary understanding remains a significant challenge for many faithful.

Incompatible with the Catholic Faith

The Catholic Church teaches that this position is incompatible with the promises of Christ. Jesus promised that “the gates of hell would not prevail” against His Church (Matthew 16:18) and that He would be with it “all days, even to the consummation of the world” (Matthew 28:20).⁷⁷ The idea that the entire hierarchy of the Church—every bishop in the world—could fall into apostasy with no one noticing, and that the See of Peter could remain vacant for over 60 years, contradicts this divine promise of the Church’s indefectibility (her quality of lasting until the end of time).⁷⁷

The Sedevacantist position, born of a desire to protect tradition, tragically demonstrates the absolute necessity of a living, visible authority in the Church. Without the Pope, the rock of unity, there is no final arbiter to interpret tradition. This inevitably leads to further fragmentation, with different groups disagreeing on when the papacy was lost or even electing their own “popes”.⁷⁸ It is a sorrowful but powerful testament to the fact that the papacy is not an arbitrary power structure, but a gift from Christ Himself, essential for preserving the very unity and truth that all Catholics hold dear.

What Does “Full Communion” Truly Mean for a Believer?

Throughout our journey, we have used the term “full communion.” This is not just a technical or legal term; it is a description of a powerful spiritual reality. It means being fully united in the one family of God, sharing a common life that is nourished by the same faith and the same sacraments.⁶

The Three Bonds of Communion

The Catholic Church teaches that full communion requires unity in three essential areas 6:

1. Profession of Faith: We believe and profess the same essential truths of the faith, handed down from the Apostles.
2. Sacraments: We celebrate the same seven sacraments, which are the life-giving channels of God’s grace.
3. Pastoral Governance: We are united under the visible leadership of the Pope, the successor of St. Peter, and the bishops in communion with him.

When these three bonds are intact, we are in full communion. The ultimate meaning of this communion, But is not merely organizational. It is a participation in the very life of the Holy Trinity, a life that is offered to us through Christ in the sacraments. The institutional bonds of faith, sacraments, and governance are the visible, earthly structures that God has given us to safeguard this invisible, divine reality.

The Eucharist: The Heart of Communion

The most powerful and visible sign of our full communion is sharing together in the Holy Eucharist.⁶ The Eucharist is the “source and summit of the Church’s life”.⁸⁴ The Catechism teaches that the Eucharist makes the Church.⁸³ When we receive the one Body of Christ, we are drawn more deeply into unity with Him and with every other member of His Mystical Body across time and space.⁸³ To be able to approach the altar and receive the Eucharist in a Catholic church is the clearest and most joyful sign that you are in full communion with the Catholic Church.⁸²

This is why our divisions are so deeply painful. When we cannot share the Eucharist with other baptized Christians—whether they are Protestant, Orthodox, or part of a group in an irregular situation—we feel the sharp sting of our separation. It is a tangible sign that we are not yet fully one as Christ prayed we would be.² This is also why receiving communion in a church with which one is not in full communion is normally not permitted; it would be a false sign, an action that claims a unity that, tragically, does not yet fully exist.⁶ The goal of all our prayers and work for unity is to bring everyone to the one Eucharistic table, where we can all receive the “medicine of immortality” and a “pledge of the life to come”.⁸⁸

How Should We, as Faithful Christians, Respond to These Divisions?

Our journey through the many branches of our Catholic family can leave us with mixed feelings: deep gratitude for its richness and diversity, but also powerful sorrow for its fractures. Our first response, then, must be one of humility, recognizing that sin—our own and that of our ancestors—is at the root of these divisions. But this humility must be steeped in an unshakeable hope, trusting not in our own efforts, but in Christ’s prayer and the power of the Holy Spirit to heal His Body.²

The Path of Prayer and Penance

We are not helpless observers in this sacred work. The Second Vatican Council teaches that the task of restoring Christian unity “transcends human powers and gifts”.⁵ Therefore, our primary contribution must be spiritual. We are all called to:

• Pray Constantly: We must pray without ceasing for the unity of all Christians, joining our humble prayers to Christ’s own powerful prayer to the Father.
• Live Holier Lives: The Council states that a “conversion of heart” and personal holiness are the very “soul of the whole ecumenical movement”.² The more closely we are united to Christ in our own lives, the more we will be united to one another. A Church full of saints is a Church on the path to unity.

The Dialogue of Love and Truth

We must also engage with our separated brothers and sisters in a spirit of boundless charity. This begins with a “dialogue of love,” where we learn to see them not as adversaries or statistics, but as beloved members of God’s family. We must make an effort to know them, to understand their history and beliefs from their own perspective, and to collaborate with them in works of charity and in the pursuit of justice for the poor and vulnerable.⁵ This builds the trust that is necessary for the more difficult “dialogue of truth,” where we can honestly and gently discuss our differences in doctrine, always speaking the truth in love.

Finally, the path to unity is not to water down our own faith, but to live it more authentically and joyfully. For a Catholic, this means deepening our love for the Eucharist, our tender devotion to Mary and the and our faithful communion with the Pope and our local bishop. For our Eastern Catholic brethren, it means cherishing and living out the unique and ancient rites that are their precious inheritance.⁵ A vibrant, holy, and merciful Catholic Church is the greatest gift we can offer to the cause of Christian unity.

Conclusion: Awaiting the Fullness of the Kingdom

We are a pilgrim people, journeying together toward our heavenly home.⁹⁰ On this journey, we see the Church in her earthly reality: beautiful, diverse, holy, yet wounded and in constant need of healing and purification. We must not lose heart at the sight of her wounds. The unity of the Church is a divine gift from Christ that can never be destroyed. Our sacred task is to cherish this gift, to pray for its full and visible flowering, and to be humble instruments of reconciliation in our own families, parishes, and communities. We walk forward in faith, trusting that one day, at the end of time, the Lord’s prayer will be answered in its fullness, and all the just will be “gathered together with the Father in the universal Church”.⁸⁹ Then, every division will be healed, every tear will be wiped away, and we will all be one, as the Father, Son, and Holy Spirit are one. Amen.
