Old Catholicism vs. Roman Catholicism: What’s the Difference?

 

By Dr. h.c. Miracle Gabriel-Ooc
When people hear the word Catholic, their minds always go straight to Roman Catholic. But Catholicity has never been limited to one jurisdiction. For centuries, the Catholic Church has been expressed in many sees—Jerusalem, Antioch, Alexandria, Constantinople, and yes, Rome. Old Catholicism is one of those expressions.

So, what’s the difference between Old Catholicism and Roman Catholicism? Let’s break it down:

1. Shared Foundations

Both Old Catholics and Roman Catholics believe in the same essentials of the Christian faith:

The Trinity: Father, Son, and Holy Spirit.

The divinity and humanity of Jesus Christ.

The seven sacraments (Baptism, Eucharist, Confirmation, Reconciliation, Matrimony, Holy Orders, and Anointing of the Sick).

Apostolic Succession refers to the continuous transmission of episcopal authority, passed down through generations of bishops, reaching back to the apostles themselves.

They profess the same Creed.

2. Where They Differ

The main differences are in governance and certain doctrines that developed in Rome:

Papal Authority: Old Catholics honor the Bishop of Rome as a historic patriarch, but they do not recognize universal jurisdiction or papal infallibility (declared in 1870). For Old Catholics, the Church’s leadership is collegial, modeled after the apostles who shared authority.

Local Autonomy: Old Catholic Churches are self-governing (autocephalous). Each jurisdiction manages its own affairs while staying true to the apostolic faith.

Openness in Practice: Many Old Catholic jurisdictions have adapted pastoral practices like vernacular liturgy earlier than Rome, optional celibacy for clergy, and a strong emphasis on ecumenism and unity with other Christian bodies.

3. Not “Older,” But “True to the Old”

The term “Old Catholic” doesn’t mean outdated or older than Rome. It means they hold fast to the ancient, undivided Catholic faith—St. Vincent of Lérins, writing in the 5th century, described authentic doctrine as that which has been universally held, across all times and by all the faithful.

4. Recognition

Even the Roman Catholic Church acknowledges that Old Catholic Orders and Sacraments are valid. In Dominus Iesus (2000), signed by then-Cardinal Joseph Ratzinger (later Pope Benedict XVI), Rome recognized Old Catholic Churches with apostolic succession and valid Eucharist as “true particular Churches.”

But here’s the key: "our validity doesn’t come from Rome’s recognition—it comes from Christ Himself, the Head of the Church" Bishop Obiano would say citing 1 Corinthians 3:11.

Old Catholicism and Roman Catholicism are not enemies but brothers. They share one Lord, one faith, and one baptism (Ephesians 4:5). Their differences don’t erase their common foundation in Christ.

Many folks do ask me, "If you're not under the Pope, what makes you Catholic?" This is a fair question. The answer goes back to the early Church. For the first thousand years, Christianity had five major centers (Sees)—Rome, Constantinople, Alexandria, Antioch, and Jerusalem. Each had its own traditions and leadership, yet all were united in the same faith. The Old Catholic movement seeks to return to that earlier model of the Church—where local churches have freedom while maintaining apostolic faith.

Let me share something from my own experience. When I first encountered Old Catholicism, I was surprised to see how familiar everything felt. The Mass looked almost identical to what I knew. The priest wore similar vestments, we knelt at the same parts, and the Eucharist felt just as sacred. The big differences weren't in the worship itself, but in how the church was organized and some pastoral approaches.

For example, in many Old Catholic communities, priests can marry and even their bishops. There is no compulsory celibate life. This was what surprised me at first that I asked myself, “Really?” I never knew that such would ever be seen in Catholic Church. Well, let’s not forget that Roman Catholic is just a branch of the Catholic Church—a tree (Catholic Church) with many branches (Old Catholic, Orthodox Christians, Roman Catholic, etc). This isn't something new—it's actually the ancient practice. In the early Church, many apostles and bishops were married men. Saint Peter himself had a mother-in-law, as we read in the Gospels. The rule of celibacy for priests developed gradually in the Western church over centuries. Old Catholics maintain that whether a priest is married or celibate doesn't affect his ability to celebrate valid sacraments or disqualify him from being raised to the Sacred Orders.

Another area where people notice differences is in language. Many Old Catholic churches were using local languages in Mass long before the Roman Catholic Church introduced vernacular liturgy after Vatican II. When I attended my first Old Catholic Mass in my own language—Igbo, I was struck by how much more engaged the congregation was. People understood every word and participated actively. It reminded me of what Saint Paul the Apostle wrote about speaking in words people can understand.

But don't think Old Catholicism is just about being more flexible. There's a deep commitment to tradition here. The seven sacraments are celebrated with the same seriousness. The apostolic succession—the unbroken line of bishops going back to the apostles—is carefully maintained. The Eucharist is still seen as the true Body and Blood of Christ, not just a symbol. Nothing has changed and nothing will ever change. Same tradition, same practice, same worship same sacraments , same faith and above all—the same Lord and Savior.

I remember asking Bishop Obiano about these differences. He told me, "We're like branches on the same tree. We grow in different directions, but our roots are the same." This has stayed with me. The divisions between Christians should sadden us, but they don't have to make us enemies.

In Charismatic Old Catholic Church, I've seen how Old Catholicism appeals to people who love Catholic tradition but want a more local approach to church governance. We still have bishops, priests, and deacons. We still celebrate the same liturgical year—Advent, Christmas, Lent, Easter. We still honor the saints and believe in the communion of saints. What changes is how decisions are made—more locally, with more input from clergy, laypeople together, and above all—upholding the early teachings of the early Church.

This way of being Catholic has a long history. After the First Vatican Council in 1870, many German, Swiss, and Dutch Catholics couldn't accept the new doctrine of papal infallibility. They formed what we now call the Old Catholic Churches. But this wasn't starting something new—it was continuing what they believed was the ancient Catholic faith without what they saw as later additions.

Today, Old Catholic churches exist worldwide, including here in Africa. As Bishop Obiano often says, "Our catholicity isn't measured by our connection to Rome, but by our faithfulness to Christ and the apostles' teaching." This doesn't mean we don't respect the Pope—we see him as an important Christian leader, just not as having universal jurisdiction over every Christian.

What matters most is what unites us—the same creeds, the same sacraments, the same Scriptures, and above all, the same Lord. As Saint Augustine said, "In essentials, unity; in non-essentials, liberty; in all things, charity." This wisdom guides the Old Catholic approach to being part of Christ's one, holy, catholic and apostolic Church.

So when you hear “Old Catholic,” don’t think “rival” or “breakaway.” Think of a branch of the one Catholic Church, faithfully carrying the apostolic faith—beyond Rome, yet united in Christ.
