Teacher Notes: Unit 10, The Sacraments
Why this unit matters
Students have received several sacraments and studied their rites, but often without the doctrine behind them. Many think of the sacraments as ceremonies that mark stages of life, rather than as Christ acting now. The unit gives them that doctrine, with two full lessons on the Eucharist, the “source and summit” of the Christian life.
Make the philosophy course’s lessons on substance and accident a prerequisite for 10.3. Without that distinction, transubstantiation sounds either magical or merely symbolic.
By the end of the unit, students should be able to:
- define a sacrament and explain ex opere operato, matter and form, and character;
- explain the effects of Baptism, why infants are baptised, and what the Church says about the unbaptised;
- explain the Real Presence from John 6, the early Church, and substance and accident;
- explain how the Mass is the one sacrifice of the Cross made present;
- explain the doctrine behind Penance, Anointing, Orders and Matrimony, including the difference between annulment and divorce.

Lesson 10.5 covers four sacraments and may need two periods.
Lesson by lesson
10.1 What is a sacrament?
Goal: students can explain how a sacrament differs from an ordinary sign, and what ex opere operato means.
Discussion questions:
- What is the difference between a photo of a hug and a hug? Which is more like a sacrament?
- Why might God use physical things to give spiritual gifts?
Misconceptions to watch for:
- “Sacraments work like magic.” They are Christ’s gift, received in faith; disposition affects their fruit.
- “A sinful priest’s sacraments don’t count.” Augustine’s answer to the Donatists.
10.2 Baptism and Confirmation
Goal: students can explain the effects of Baptism and the reasons for infant baptism.
Discussion questions:
- What other good things do parents give children before they can choose them? Is grace different?
- What did your Confirmation give you? What does the lesson say it gives?
Pastoral note. Some students or families may have lost a baby before baptism, through miscarriage, stillbirth or early death. Present CCC 1261 and the hope the Church expresses with great gentleness, and do not present limbo as Church teaching. Some parishes have funeral rites for children who die before baptism.
Misconceptions to watch for:
- “Unbaptised babies go to limbo.” A hypothesis, not teaching.
- “Confirmation is when you choose to be Catholic.” It is above all a gift of the Spirit.
10.3 The Real Presence
Goal: students can explain transubstantiation using substance and accident.
Activity: read John 6:51–69 aloud. Ask students to track how the crowd reacts and how Jesus responds each time. End with Peter’s answer: “Lord, to whom shall we go?”
Discussion questions:
- If Jesus meant his words only symbolically, why did he let disciples walk away?
- If the bread still looks and tastes like bread, what has changed?
Misconceptions to watch for:
- “It’s a symbol.”
- “The bread changes chemically.” Accidents remain.
- “Breaking the host breaks Christ.” The whole Christ is in every part.
Note: surveys suggest many Catholics do not know or accept the Church’s teaching on the Real Presence. Teach it confidently and clearly.
10.4 The Mass as sacrifice
Goal: students can explain how the Mass is the one sacrifice of the Cross made present, not repeated.
Discussion questions:
- What is the difference between remembering an event and taking part in it? Think of Passover.
- What do you offer at Mass?
Misconceptions to watch for:
- “The priest kills Jesus again.” The Mass is unbloody; Christ dies no more.
- “The Mass is just a meal” or “just a sacrifice”. It is both, and a memorial.
10.5 Healing and service
Goal: students can explain the scriptural basis and effects of the four sacraments of healing and service.
Discussion questions:
- Why might it help a person to say their sins aloud and hear “I absolve you”?
- What does Jesus mean by going back to “the beginning” when he talks about marriage?
Pastoral note. Some students will have divorced parents. Present indissolubility and annulment accurately but gently, without implying judgement on any family. Moral questions about marriage belong to moral theology and are outside this course.
Misconceptions to watch for:
- “I can just confess to God.” God can forgive anyone who repents, but Christ gave the Church the sacrament as the ordinary way.
- “The Anointing is only for the dying.”
- “An annulment is a Catholic divorce.”
Answer key
The answers to every Check your understanding question also appear on the lesson pages behind Show answer, and are left off printed handouts.
Lesson 10.1: (1) A visible sign, instituted by Christ, that gives the grace it signifies. (2) By the rite itself, by Christ’s power. (3) Christ baptises whoever the minister is; validity depends on Christ. (4) Baptism: water and the Trinitarian formula. Eucharist: bread and wine and the words of consecration. (5) Valid: really happens. Fruitful: bears its effect, depending on disposition.
Lesson 10.2: (1) Any three of: forgiveness, new birth, membership in the Church, character. (2) Household baptisms in Acts; Origen; the Apostolic Tradition. (3) Blood: dying for Christ unbaptised. Desire: wanting baptism but dying first. (4) Entrusted to God’s mercy with hope; limbo is not teaching. (5) Completes baptismal grace, gives the Spirit, strengthens for witness.
Lesson 10.3: (1) True, real, substantial presence; transubstantiation; only appearances remain. (2) Jesus repeated his words and let disciples leave. (3) The substance changes; the accidents remain. (4) Science measures accidents, which do not change. (5) Yes; the whole Christ is in each form and every part.
Lesson 10.4: (1) Same victim and offerer; different manner, bloody and unbloody. (2) It makes the one sacrifice present; it does not add another. (3) A memorial makes a past saving event present, as Passover does the Exodus. (4) The Didache; Augustine. (5) All the faithful offer Christ and themselves with him.
Lesson 10.5: (1) John 20:22–23; forgiving or retaining requires knowing the sins. (2) Contrition, confession, satisfaction. (3) The seriously ill and elderly; strength, union with Christ’s suffering, forgiveness, sometimes healing. (4) Bishop, priest, deacon. (5) Divorce claims to dissolve a marriage; nullity finds there never was a valid one.
