Domestic Seminary

Year 6: What Is the Mass?

Age Range: 11-12 years (school Year 6)
Core Themes: Mass as sacrifice, liturgical participation, Eucharistic amazement, priesthood
Primary Sources:

SECTION A: Driving Questions

This year transforms Mass from obligation to encounter. Pre-teens are ready to understand the deep structure and cosmic significance of the liturgy, moving beyond mere attendance to active participation in Christ’s eternal offering.

SECTION B: Doctrinal Content

Question: Whether the Mass is truly the same sacrifice as Calvary?

Objection 1: It seems the Mass cannot be the same sacrifice as Calvary because Christ died once for all¹ and cannot die again.

Objection 2: Furthermore, a sacrifice requires suffering and death, but Christ in heaven can no longer suffer or die.

Objection 3: Moreover, if Calvary was sufficient, repeating it seems to imply it wasn’t enough.

On the contrary, at the Last Supper, Christ said “Do this in memory of me”², and the Church has always understood this as making present His one sacrifice.

I answer that the Mass is not a new sacrifice but the same sacrifice of Calvary made present in an unbloody manner. This is one of the deepest mysteries of our faith!

Think of it this way: Imagine you could travel back in time to be present at the most important moment in history. That’s what happens at Mass—except instead of us traveling back, that moment travels forward to us!

Here’s how it works:

It’s like watching a live event versus watching it on TV:

Reply to Objection 1: Christ doesn’t die again. The one death is made present. Like the sun is one but its light reaches many places, the one sacrifice reaches across all time.

Reply to Objection 2: The glorified Christ presents His once-for-all sacrifice eternally to the Father. The Mass connects us to this heavenly liturgy.

Reply to Objection 3: Calvary was completely sufficient! The Mass doesn’t add to it but applies its infinite merits to us here and now.

The Structure of Mass: Entering the Heavenly Liturgy

Question: Why does the Mass follow such a specific structure?

I answer that the Mass structure isn’t arbitrary but follows the pattern of heavenly worship and salvation history. Every Mass has two main parts that mirror our entire relationship with God:

1. LITURGY OF THE WORD: God Speaks to Us

This is like the Old Testament: God revealing Himself to His people

2. LITURGY OF THE EUCHARIST: We Offer and Receive

This is the New Testament: Christ offering Himself and us receiving Him

Every gesture has meaning:

The Eucharistic Prayer: Heart of the Mass

During the Eucharistic Prayer, heaven and earth meet:

1. Preface and Sanctus We join the angels singing “Holy, Holy, Holy”—we’re literally in God’s throne room!

2. Epiclesis (Calling Down the Spirit) The priest asks the Father to send the Holy Spirit to transform the gifts

3. Institution Narrative Christ speaks through the priest: “This is my body… This is my blood”

4. Mystery of Faith We proclaim the entire Gospel in one sentence

5. Anamnesis and Offering We remember (make present) Christ’s sacrifice and offer ourselves with Him

6. Intercessions We pray for the Church, living and dead—all connected in one Body

7. Doxology “Through Him, with Him, in Him”—we offer all glory to the Father

SECTION C: Thinking and Reflection Activities

📖 Scripture Meditation: The Road to Emmaus

Read: Luke 24:13-35

Picture It: You’re walking with the disciples, sad about Jesus’ death. A stranger joins you and explains Scripture. Then at dinner…

Think:

Connect: At Mass, we too meet Jesus in Word and Eucharist. Do we recognize Him?

Do: This Sunday, ask Jesus to open your eyes during the breaking of bread.

SECTION D: Integration With Life

🧍🏽 Real-World Moral Scenario

The Sunday Sports Dilemma

You made the travel soccer team—congratulations! But tournaments are on Sundays. The coach says, “Missing games means less playing time.” Your parents are torn. Options:

  1. Quit the team
  2. Skip Mass during soccer season
  3. Find Saturday evening Mass
  4. Talk to coach about arriving late

Deeper Questions:

Possible Solution: Saturday evening Mass + explain to coach that faith commitment actually makes you more disciplined. Some pro athletes do this!

Remember: We don’t go to Mass because we “have to” but because we “get to” participate in the most important event in the universe!

🛠 How to Respond When…

“Mass is boring!” “I understand it can seem that way sometimes! But imagine if you went to a concert in a language you didn’t understand—it might seem boring too. Mass is in a ‘language’ of symbols and rituals we need to learn. Also, ‘boring’ might mean you’re ready for deeper participation. Here’s what helps: 1) Follow along in a missal, 2) Offer each part for someone specific, 3) Look for one new detail each week, 4) Remember you’re at Calvary—the most dramatic event ever! The angels aren’t bored at Mass; they’re in awe. Ask the Holy Spirit to show you what they see.”

“Why can’t we have Mass in our living room?” “Great question! Technically, Mass CAN be celebrated anywhere in emergencies. But normally it’s in church because: 1) Sacred space helps us focus on sacred realities, 2) It gathers the whole community, not just friends, 3) The altar represents both the Last Supper table AND Calvary’s altar of sacrifice, 4) Churches are consecrated—set apart for God, 5) It connects us to centuries of Christians who worshipped in that place. Your living room is the ‘domestic church’ where family prayer happens, but Sunday Mass needs the whole Church family!”

“Why do we keep saying ‘Lord, have mercy’ if we’re already forgiven?” “Think of it like this: When you come in from playing outside, you wash your hands even if they’re not filthy. The Penitential Rite is like spiritual hand-washing—it prepares us for the holy things we’re about to do. Also, we’re acknowledging our constant need for God’s mercy, not earning it through repetition. It’s like saying ‘I love you’ to your parents—you don’t say it once and never again! Each Mass, we remember we’re sinners saved by grace, which keeps us humble and grateful.”

“My Protestant friend says Catholic Mass is unbiblical” “Actually, the Mass is SATURATED with Scripture! About 80% of the Mass comes directly from the Bible. The structure follows Jewish worship that Jesus knew. Every prayer has biblical roots. For example: ‘Lord, have mercy’ (Matthew 15:22), ‘Glory to God’ (Luke 2:14), ‘Holy, Holy, Holy’ (Isaiah 6:3), ‘Lamb of God’ (John 1:29). The Eucharistic Prayer closely follows ancient Jewish blessing prayers. Even vestments and incense are biblical (Exodus 28, Revelation 8). Your friend might not recognize it because Protestants often use different worship styles, but Catholic Mass is deeply biblical worship!”

🛑 What Not To Say

❌ “Just sit still and be quiet” ✅ Say: “Let’s participate actively in the prayers and responses”

❌ “Father’s homily was boring” ✅ Say: “What was one thing Father said that we can think about?”

❌ “We go to Mass because we have to” ✅ Say: “We go to Mass because we get to participate in heaven on earth”

❌ “That altar server did it wrong” ✅ Say: “Serving at Mass is hard; let’s pray for all who serve”

❌ “Hurry up, let’s beat traffic” ✅ Say: “Let’s thank Jesus for coming to us before we leave”
