The Catholic Mass is the main prayer Catholics share together, and it always follows the same four parts: the Introductory Rites, the Liturgy of the Word, the Liturgy of the Eucharist, and the Concluding Rites. If it's your first time, relax: you don't need to know the prayers ahead of time. Arrive a few minutes early, follow the people around you, and stay in your pew during Communion if you aren't receiving.
The four parts of the Catholic Mass
Some details change with the season of the year and the day of the week, but this order stays the same at any Sunday Mass in your parish. The two main parts are the Liturgy of the Word and the Liturgy of the Eucharist. The opening and the closing are shorter and frame them.
Introductory Rites
This is the opening. It brings everyone together and gets you ready to listen and to pray. The priest and ministers walk in while people sing, and the priest bows to the altar and kisses it. Then everyone makes the Sign of the Cross: “In the name of the Father, and of the Son, and of the Holy Spirit. Amen.”
The priest greets everyone, often with “The Lord be with you,” and you answer “And with your spirit.” Next comes the Penitential Act, a short moment where everyone admits their sins together and asks for God's mercy. It isn't the same as going to Confession. One common form begins “I confess to almighty God and to you, my brothers and sisters.” The Kyrie comes right after it or as part of it: “Lord, have mercy. Christ, have mercy. Lord, have mercy.”
On Sundays outside Advent and Lent, and on feast days, everyone sings or says the Gloria, which begins “Glory to God in the highest.” Then the priest says the opening prayer, called the Collect. It gathers everyone's intentions and sets the tone for that day's Mass.
Liturgy of the Word
Now everyone listens to the Bible. On Sundays you'll usually hear a first reading, a psalm with a short response that everyone repeats, a second reading, and the Gospel. After each of the first two readings, the reader says “The word of the Lord,” and you answer “Thanks be to God.”
Everyone stands for the Gospel, because it tells the life and teaching of Jesus. At the end, you'll hear “The Gospel of the Lord,” and you answer “Praise to you, Lord Jesus Christ.”
Then comes the homily. The priest or deacon explains the readings and helps everyone connect God's Word with daily life. On Sundays and on the biggest feast days, everyone then says the Creed together. It begins “I believe in one God.” This part ends with the Prayer of the Faithful, also called the Universal Prayer. These are short prayers for the Church, for public leaders, for people in need, and for the local community. In many parishes you answer each one with “Lord, hear our prayer.”
You don't need to know every response before your first visit. Listen, follow the people around you, and use the worship aid, the printed booklet or sheet, if the parish has one. If you'd like to get to know the Bible better, see our guide to choosing a Catholic Bible.
Liturgy of the Eucharist
This part starts as the altar is prepared. The bread and wine are brought to the front, and the priest prepares them for the Eucharistic Prayer. There's often a collection for the parish and its work with people in need. If you're visiting, you don't have to give anything.
The Eucharistic Prayer is the center of this part. The priest thanks God, asks the Holy Spirit to come, repeats the words and actions of Jesus at the Last Supper, and offers Jesus' sacrifice to the Father. You join in by praying quietly and with a few short answers, sung or said:
- Holy, Holy, Holy (the Sanctus): “Holy, Holy, Holy Lord God of hosts.”
- The Memorial Acclamation. One common form is “We proclaim your Death, O Lord, and profess your Resurrection until you come again.”
- The Great Amen. Everyone answers with a strong “Amen” at the end of the prayer.
Then comes the Communion Rite. Everyone prays the Lord's Prayer together: “Our Father, who art in heaven.” Next you share a sign of peace with the people around you, in the way that's usual in that parish. Many people simply say “Peace be with you.” Then everyone sings or says the Lamb of God: “Lamb of God, you take away the sins of the world, have mercy on us.” The priest receives Communion first. Then Catholics who are ready to receive come forward, usually those who have made their First Communion and have been to Confession if they need it.
Holy Communion is a sacrament and a sign of full unity in the Catholic faith. So if you're a Christian from another church, if you belong to another faith, or if you're a Catholic who isn't receiving that day, you can simply stay in your pew and pray. Everyone who comes is welcome to pray for unity and peace during this time.
After Communion there's a moment of silence or a song. Then the priest says the Prayer after Communion, asking that the sacrament bear fruit in everyone's life.
Concluding Rites
The ending is short. There may be parish announcements after the Prayer after Communion. Then the priest blesses everyone: “May almighty God bless you, the Father, and the Son, and the Holy Spirit,” and you answer “Amen.” The deacon or priest sends everyone out, for example with “Go forth, the Mass is ended,” and you answer “Thanks be to God.”
That sending out matters, because the Mass doesn't stay inside the church. You're sent to live what you just celebrated during the rest of the week: by praying, by serving and helping others, and by showing your faith in how you live.
What a first time visitor can do
You can go to a Catholic Mass even if you aren't Catholic. Arrive a few minutes early, sit where you can see and hear, and silence your phone. You can join in the spoken answers and the songs, or just listen quietly.
People stand, sit, and kneel at different moments. These postures are a way of paying attention, showing respect, and praying together. They can change a little from one country or diocese to another. If your health or mobility keeps you from standing or kneeling, that's okay. Follow everyone else when you can, and don't worry if you miss a move.
To get ready for your visit, use this simple plan:
- Check the parish website for the Mass time and language.
- Arrive early enough to find a seat without rushing.
- Follow the worship aid, or watch the people around you for the responses and postures.
- Notice the big moments: the readings, the Gospel (everyone stands), the Our Father, and Communion.
- During Communion, stay in your pew if you aren't receiving.
- Stay until the dismissal and the closing procession.
If you bring children, tell them church is a quiet place to pray. If your little one gets fussy, it's fine to step out for a moment and come back. Many parishes welcome families with young children and have accessible seating. If you need any accommodation, contact the parish before your visit.
What the Catholic Mass is
The Mass is more than a meeting, a class, or a private prayer. Catholics believe Jesus is truly present there, and in a unique way in the consecrated bread and wine. The word Eucharist means thanksgiving, and the whole Mass is a way of thanking God together: people listen, answer, sing, keep silence, and pray for the Church and the world.
The Eucharist is one of the seven sacraments of the Catholic Church, and Mass is where it is normally celebrated.
A simple way to follow the whole celebration
Remember four words: gather, listen, give thanks, and go.
- Gather. The Introductory Rites bring everyone together.
- Listen. The Liturgy of the Word is the time to listen to God's Word.
- Give thanks. The Liturgy of the Eucharist is the great thanksgiving, with Holy Communion.
- Go. The Concluding Rites send everyone out into the world.
You don't need to understand every prayer on your first visit. Start with these four parts, notice how the readings lead into the Eucharist, and let the responses and the moments of silence show you how Catholics pray together. If you'd like a way to pray on other days of the week, see our guide to praying the Rosary step by step.

Common questions about the Catholic Mass
What happens during a Catholic Mass?
Everyone gathers, listens to readings from the Bible, and prays together. Then the Eucharist is celebrated, and Catholics who are able and prepared receive Holy Communion. At the end, everyone is sent out to live the Gospel. Music, silence, gestures, and standing, sitting, or kneeling go along with each part.
What are the four parts of the Catholic Mass?
The four parts are the Introductory Rites, the Liturgy of the Word, the Liturgy of the Eucharist, and the Concluding Rites. The Church's official instructions also describe the Mass as two main parts, the Word and the Eucharist, with an opening and a closing around them.
Can a non Catholic attend Mass?
Yes. Catholic parishes welcome visitors to come and pray. If you aren't Catholic, you usually don't receive Holy Communion, because Communion is a sign of full unity in the Catholic faith. You can stay in your pew and pray while others go up to receive.
