When Did the Catholic Church Begin? Who Founded It?

When did the Catholic Church begin?

Not in the fourth century. Not with Constantine. Not at the Council of Nicaea.

If we are going to answer the question historically and biblically, we have to start where Christianity itself starts: with Jesus Christ and the apostles.

Jesus did not write a book and tell future Christians to figure everything out for themselves. He gathered disciples, chose twelve apostles, gave them authority, appointed Peter to a unique role among them, promised to build His Church, and sent the Holy Spirit to guide it.

That is where the Catholic Church says its history begins. The question is not when the word Catholic eventually became a common name for the Church. The question is much more fundamental:

What Church did Jesus Christ actually establish?

Jesus Said He Would Build His Church

Jesus did not say, “I will leave behind a collection of writings and someday Christians can establish churches based upon how they interpret them.”

He said:

“You are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. I will give you the keys to the kingdom of heaven.”

— Matthew 16:18–19

Notice what Christ Himself establishes.

• There is a Church.
• There is identifiable leadership.
• There is authority.
• There are the keys of the kingdom.

And there is a promise that the powers of death will not overcome what He establishes. Matthew's Gospel explicitly records Christ giving Peter the keys and the authority to bind and loose. That is a very different picture from Christianity as thousands of independent congregations and individuals deciding for themselves what Scripture means. This is why the question of authority in Christianity matters so much. Before arguing about Mary, the Eucharist, baptism, confession, salvation, or any other doctrine, we first have to answer a simpler question:

Who did Christ authorize to teach Christianity?

When Did the Catholic Church Begin?

The Catholic answer is straightforward:

Jesus Christ founded the Church during His earthly ministry and entrusted it to His apostles.

After His Resurrection, Christ did something remarkable. He appeared to the apostles and said:

“As the Father has sent me, so I send you.”

Then Scripture tells us:

“He breathed on them and said to them, ‘Receive the holy Spirit.’”

— John 20:21–22

He immediately connected that commission with the authority to forgive and retain sins.

That wasn't a group of people creating their own religious organization. Christ was commissioning men He had personally chosen and giving them spiritual authority to continue His mission. John places this giving of the Spirit on Easter evening.

And then came Pentecost.

Pentecost: The Birthday of the Church

Pentecost is traditionally regarded as the birthday of the Church. The apostles were gathered together when the Holy Spirit descended upon them. They were filled with the Spirit and began proclaiming the Gospel. Peter stood before the crowd and preached Christ publicly. People responded, were baptized, and the Christian community exploded into public view.

Acts 2 does not describe people getting together and deciding to start Christianity.

It describes the Church Christ had already established being empowered by the Holy Spirit and sent into the world. The Church therefore speaks of Pentecost as her birth or public manifestation.

Think about what we already have by the opening chapters of Acts:

• Jesus Christ.
• Peter.
• The apostles.
• Teaching authority.
• Baptism.
• The forgiveness of sins.
• The Eucharistic breaking of bread.
• A visible community.
• The Holy Spirit guiding and empowering that community.

That is Christianity before there was a New Testament collection and centuries before Constantine was born. So when someone claims that the Catholic Church was invented hundreds of years later, we should ask a very simple question: What exactly do they think this Church in Acts was?

Did Constantine Start the Catholic Church?

This is one of the most persistent claims made against Catholicism: “Constantine created the Catholic Church.”

There is an obvious historical problem with that argument.

Constantine convened the Council of Nicaea in A.D. 325. But who attended Nicaea?

Christian bishops.

• There were already bishops.
• There were already priests and deacons.
• There were already Christian communities spread throughout the ancient world.
• There was already a recognized body of Christian doctrine.
• There were already disputes over how that inherited faith should be understood.

The Council of Nicaea was an assembly of Christian bishops addressing a major controversy concerning the identity of Christ. You cannot invent a Church by calling together bishops of a Church that already exists. Constantine did not create Christianity at Nicaea. He walked into a Christian world that had already existed for nearly three centuries. In Catholics Are Wrong, Says Who? I show how the Council of Nicaea actually offers solid proof that the Catholic church is the one holy and apostolic church founded by Christ himself.

And those centuries included brutal persecution of Christians who were willing to die for a Church supposedly not yet invented.

Who Founded the Catholic Church?

Age alone does not prove that a Church is true. The point is much more specific. Every Christian community has an identifiable history. When we trace Lutheranism backward, we eventually reach Luther. Trace Methodism backward and we reach Wesley. Trace Mormonism backward and we reach Joseph Smith. But when the Catholic Church traces its bishops, sacraments, teaching authority, and apostolic succession backward, its claim leads beyond Constantine, beyond Nicaea, and through the early Church to the apostles themselves. That is the claim that has to be answered.

This is where the issue becomes uncomfortable for some Christians. Ask who founded Lutheranism and history points you to the Reformation. Ask when Methodism emerged, and history takes you to the eighteenth century. Ask when modern Pentecostalism arose and you arrive in the twentieth century. But when Catholics are asked who founded their Church, the Catholic claim is not a medieval pope, Constantine, or some theologian in the fourth century. The answer is: Jesus Christ. And Catholicism claims continuity not merely through a set of ideas but through the apostolic Church itself: bishops succeeding bishops, the sacraments being celebrated, the Gospel being preached, and the faith being handed from one generation to the next. That claim can certainly be challenged. But it cannot simply be dismissed by saying, “The Catholic Church didn't exist until Constantine.” The New Testament itself forces us further back.

If someone believes the Catholic Church somehow ceased to be Christ's Church, another question immediately follows: When did that happen? Where is the historical moment when the Church Christ established disappeared, and where did Christ authorize someone centuries later to start another one?

The Name Came Later. The Church Did Not.

Someone may respond: “But the Bible never calls it the Roman Catholic Church.” True. The Bible doesn't use the word Trinity either. That does not mean Father, Son, and Holy Spirit were invented when Christians eventually adopted a theological word to describe what they already believed.

Names develop. Terminology becomes more precise. Institutions acquire descriptive titles as historical circumstances require them.

The real question is not:

“When did Christians begin using this exact English name?”

The real question is:

“Can the Catholic Church trace what it is back to the Church established by Jesus and governed by His apostles?”

That is the question worth debating.

Follow the Church Backward

Start with the Catholic Church today and move backward. Before the Protestant Reformation, it is there. Before the Middle Ages, it is there. Before Constantine, Christians are already worshiping, baptizing, celebrating the Eucharist, appointing bishops, defending doctrine, suffering martyrdom, and preserving the faith received from those before them.

Continue backward, and eventually you arrive at Acts. Keep going, and you arrive at the apostles. And standing at the beginning is Jesus Christ saying:

“I will build my Church.”

That is why the Catholic claim is so difficult to escape. Catholicism is not claiming to have discovered the original Church.

It is claiming to be that Church in historical continuity.

You may disagree with that claim. But if you are going to say Catholics are wrong, there is another question you eventually have to answer:

Says Who?

Every disagreement about Christianity eventually becomes a disagreement about authority. If two sincere Christians read the same Bible and reach opposite conclusions, citing another verse doesn't necessarily solve the problem. Someone still has to answer: Who has the authority to determine what Christianity actually teaches? That is the question at the heart of my book Catholics Are Wrong… Says Who?.

Instead of trying to win hundreds of separate arguments about Catholic doctrines, the book goes underneath them and addresses the question that comes first: Who did Jesus authorize to speak for His Church?

And once that question is answered, many of the arguments that seem so complicated become remarkably simple.
