Why a Church?

Why not just me and Jesus? The first Christians had an answer.

The Church teaches that Jesus himself founded the Church and gave it a shape, with the Twelve and Peter at its head.12 Scripture calls it his body.3

Journeys / Becoming Catholic / Step 2 of 6

Jerusalem, the day of Pentecost

The friends of Jesus are all together in one house.4 Suddenly there is a sound from heaven, “as of a mighty wind coming,” and it fills the whole house.5

Something like tongues of fire appears and rests on each one of them.6 By the end of that day, about three thousand people have been baptized.7

And then they do something many people today find surprising. They do not each go home and follow Jesus in their own way.

01The question

Why not just me and Jesus?

You may have heard it, or said it: “I love Jesus. I just don’t need a Church.” It is a fair question. Here is what those first three thousand did.

“And they were persevering in the doctrine of the apostles and in the communication of the breaking of bread and in prayers.”

Acts 2:428

Teaching. Meals. Prayer. Together. From the very first day.

The Church teaches that Jesus himself began this community.1 He gave it a shape, beginning with the choice of the Twelve, with Peter as their head.2

Then, on a road outside Damascus, Jesus made the point himself. In one sentence.

02The turn

“Why persecutest thou me?”

A man named Saul is on his way to Damascus with letters from the high priest, to arrest any followers of Jesus he can find.14 Near the city, a light from heaven flashes around him.15

“And falling on the ground, he heard a voice saying to him: Saul, Saul, why persecutest thou me? Who said: Who art thou, Lord? And he: I am Jesus whom thou persecutest. It is hard for thee to kick against the goad.”

Acts 9:4-516

Listen to the words. Not “why are you persecuting my followers.” Me. Hurt them, and you hurt him.

Saul, also called Paul,17 later wrote to Christians in Corinth: “you are the body of Christ.”3 The Church teaches that Christ “is the head of the body, the Church.”18

“And if one member suffer any thing, all the members suffer with it: or if one member glory, all the members rejoice with it. Now you are the body of Christ and members of member.”

1 Corinthians 12:26-2719

So what kind of body is it? Every Sunday, Catholics answer in four words.

03The four words

One, holy, catholic, apostolic

In the Creed, the short statement of faith said at Mass, the Church is professed to be one, holy, catholic and apostolic.2021

<b>One</b>, because it has one source, one founder and one soul: God, Christ and the Holy Spirit.22

<b>Holy</b>, because Christ gave himself up for her, to make her holy.23

<b>Catholic</b>, a word that means “universal”: the Church is sent to the whole human race.2425

<b>Apostolic</b>, because it is built on the apostles, and the bishops carry on their mission as their successors.2612

The Pope, as Peter’s successor, is “the perpetual and visible source and foundation of the unity” of the bishops and of all the faithful.13

Holy? You may be thinking of the headlines. That is fair. Keep reading.

04The honest part

Holy, and full of sinners

The Church does not claim to be a club of perfect people. It calls itself “at once holy and always in need of purification.”27

“All members of the Church, including her ministers, must acknowledge that they are sinners.” In everyone, “the weeds of sin will still be mixed with the good wheat of the Gospel until the end of time.”27

If you have been hurt by Catholics, that matters. You do not have to pretend otherwise, and you can take all of this slowly. A good priest will want to hear it.

Which brings it back to you, and to whoever first told you about Jesus.

05The ending

No one believes alone

Think of the first person who showed you something of Jesus. A grandparent. A friend. A teacher. A stranger, maybe.

The Catechism puts it simply: “No one can believe alone, just as no one can live alone.” The believer has received faith from others and should hand it on to others.28

That is why the Church calls herself a mother: her faith comes before ours, gives birth to it, and keeps feeding it.29

On Pentecost, three thousand people found they belonged to something bigger than themselves. There is still room.

Your move

Try this, this week

  1. Read Acts 2:42-47. Notice what the first Christians did together.
  2. Visit a parish once, just to look. Sit at the back. Nobody will ask you to do anything.
  3. Name the people who passed faith to you. A grandparent, a friend, a teacher.
  4. Say what hurts, if something does. A good priest will want to hear it.

You’ll need

  • A Bible, open to Matthew 16 and Acts 2.
  • An honest question about the Church, if you have one.

Remember No one comes to faith alone.

Optional: watch a short film

Video: Can’t I Go Straight to Jesus? Do I Need the Catholic Church? [Fr. Mike Weighs In], Ascension Presents (Ascension). Link checked 4 October 2026. Loads from YouTube (privacy-enhanced mode) only when you press play. Watch on YouTube

What this video covers (summarized from the publisher’s description, not a transcript): Fr. Mike Schmitz takes up the objection that “the middleman is a lie”: if Jesus is the one mediator, why have an institutional Church? He also offers guidance for anyone frustrated by the human and sinful side of the Church.

What the Church teaches on this: The Church teaches that all her members, including her ministers, must acknowledge that they are sinners, and that she is at once holy and always in need of purification. CCC 827

Videos come from faithful Catholic teachers. Where a video and this page differ in wording, the Catechism and Scripture cited here are the authority.

If this is hard

If you have been hurt by the Church or by Catholics, that matters, and you do not have to pretend otherwise. You can take this slowly. A good priest will want to hear about it, privately and without judgment.

How to talk to a priest

Two questions people ask

Can’t I just follow Jesus on my own?

The Church teaches that faith is a personal act, but not an isolated one: “No one can believe alone, just as no one can live alone.”28 The Catechism calls believing an ecclesial act, because the Church’s faith precedes, engenders, supports and nourishes our own.29

Why does the Church have a Pope?

The Catechism teaches that the Lord made Simon, whom he named Peter, the “rock” of his Church and gave him the keys.3031 The Pope, Bishop of Rome and Peter’s successor, is the perpetual and visible source and foundation of unity for the bishops and the whole company of the faithful.13

Does the Church say people outside it cannot be saved?

The Church teaches that all salvation comes from Christ the Head through the Church which is his Body.32 It also teaches that those who, through no fault of their own, do not know the Gospel of Christ or his Church, but seek God with a sincere heart and, moved by grace, try to do his will as they know it through their conscience, may achieve eternal salvation.33

Only one thing to do

Your one next step

Step inside a Catholic church once this week, just to look. Many are open during the day. Sit at the back for five minutes. Nobody will ask you anything.

Find a church near you

Step 2 of 6 · Becoming Catholic

Jesus touched the sick and broke bread with his friends. Does he still meet people in ways they can see and hold?
