All 8 steps in Becoming Catholic You’re on step 2
Jerusalem, the day of Pentecost
Jesus’ friends are packed into one house.4 Out of nowhere there’s a sound from heaven, “like the rushing of a mighty wind,” and it fills the place.5
Something like flames settles on each one of them.6 By the end of the day, about three thousand people have been baptized: not a bad first day.7
And then they do something that surprises a lot of us today. They don’t all go home and follow Jesus in their own way.

An unbroken handing-on
From the apostles to your bishop
Your parish priest isn’t freelancing. There’s a line of hands laid on heads that goes back to the people who ate with Jesus.
- Jesus chooses the Twelve
He makes them a lasting college, with Peter at its head.34
- Peter, the rock
Christ gives Simon alone the keys.30
- The apostles appoint successors
So the mission wouldn’t die with them.35
- Bishops today
The bishops succeed the apostles; the Pope succeeds Peter.12
01The question
Why not just me and Jesus?
Maybe you’ve heard it, or said it: “I love Jesus. I just don’t need a Church.” Honest question. So here’s what those first three thousand actually did.
“They continued steadfastly in the apostles’ teaching and fellowship, in the breaking of bread, and prayer.”
Teaching. Meals. Prayer. Together. Day one.
This wasn’t a fan club that formed after He left: Jesus Himself started it.1 And he gave it a shape, starting with the Twelve, with Peter at their head.2
Then, on a road outside Damascus, Jesus makes the point Himself. One sentence.
02The turn
“Why do you persecute me?”
A man named Saul is headed to Damascus with arrest warrants, hunting Christians.14 Near the city, a light from heaven flashes all around him.15
“He fell on the earth, and heard a voice saying to him, ‘Saul, Saul, why do you persecute me?’ He said, ‘Who are you, Lord?’ The Lord said, ‘I am Jesus, whom you are persecuting.”
Listen closely. Not “why are you persecuting my followers.” Me. Mess with them, you’re messing with him.
That same Saul (you know him as Paul)17 later writes to the Christians in Corinth: “you are the body of Christ.”3 And Christ “is the head of the body, the Church.” So you can’t really love the head and ignore the body.18
“When one member suffers, all the members suffer with it. When one member is honored, all the members rejoice with it. Now you are the body of Christ, and members individually.”
So what kind of body is it? Catholics answer in four words every Sunday.
03The four words
One, holy, catholic, apostolic
In the Creed, said at every Sunday Mass, the Church is called one, holy, catholic and apostolic.2021
One: one source, one founder, one soul, namely God, Christ and the Holy Spirit.22
Holy: not because the people are, but because Christ gave Himself up for her to make her holy.23
Catholic: it means “universal”, so everybody’s invited, the whole human race.2425
Apostolic: built on the apostles, with bishops carrying their mission forward as their successors.2612
And the Pope, as Peter’s successor, is “the perpetual and visible source and foundation of the unity” of the bishops and everyone else. Christ gave Peter that job; it got passed on.13
Holy? You might be thinking about the headlines right now. Fair. Keep reading.
04The honest part
Holy, and full of sinners
The Church has never claimed to be a club for perfect people. She calls herself “at once holy and always in need of purification.” Basically: a hospital, not a museum.27
“All members of the Church, including her ministers, must acknowledge that they are sinners.” Priests, bishops, you, me: in everyone, “the weeds of sin will still be mixed with the good wheat of the Gospel until the end of time.”27
If Catholics have hurt you, that matters. You don’t have to pretend it didn’t happen, and you can take this as slowly as you need. A good priest will want to hear about it. Really.
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 grandma. A coach. A friend in college. A stranger, maybe.
The Catechism nails it: “No one can believe alone, just as no one can live alone.” Somebody handed faith to you, and someday you’ll hand it to somebody else.28
That’s why the Church calls herself a mother: her faith was there before yours, gave birth to it, and keeps feeding it.29
On Pentecost, three thousand people found out they belonged to something way bigger than themselves. There’s still room. Plenty.
Your move
Try this, this week
- Read Acts 2:42-47. Notice what the first Christians did together.
- Visit a parish once, just to look. Sit at the back. Nobody will ask you to do anything.
- Name the people who passed faith to you. A grandparent, a friend, a teacher.
- 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.
If this is hard
If you’ve been hurt by the Church or by Catholics, that matters, and you don’t have to pretend otherwise. You can take this slowly. A good priest will want to hear about it, privately and without judgment.
Three questions people ask
Can’t I just follow Jesus on my own?
Answered on video by Fr. Mike Schmitz · Full answer page
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?
Answered on video by Ascension Presents · Full answer page
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?
Answered on video by Catholic Answers · Full answer page
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, don’t 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.
