Teacher Notes: Unit 9, The Church
Why this unit matters
Many students see the Church as an institution they belong to, rather than as something they believe in. Some feel the gap between the Church’s claims and its failures very sharply, especially after the abuse crisis. This unit presents the Church as part of the content of the faith: founded by Christ, his Body, holy in its source though full of sinners, and the way salvation reaches the world.
Lesson 9.4 is the hardest in the course. It is flagged in the guide for teachers, and has extra guidance below.
By the end of the unit, students should be able to:
- show from Scripture that Christ intended a community with a structure;
- explain the Church as both visible society and Mystical Body;
- explain the scriptural basis for Peter’s primacy and the early evidence for Rome’s authority;
- explain the relationship between the Pope and the bishops;
- name and explain the four marks, and explain how a Church of sinners can be holy;
- explain “outside the Church no salvation” accurately, avoiding both rigorism and indifference.

Lesson by lesson
9.1 Founded by Christ
Goal: students can show that Christ intended a Church, and explain the Church as both visible and invisible.
Discussion questions:
- Is it possible to follow Jesus without the Church? What would be lost?
- Why do you think Christ asked Saul “why do you persecute me?” rather than “my followers”?
Misconceptions to watch for:
- “The Church is the priests and bishops.” Every baptised person is a member.
- “The Church was invented after Jesus by Paul or Constantine.” Use the stages table.
9.2 Peter and the bishops
Goal: students can explain the keys passage and the early evidence for Rome’s authority.
Activity: read Isaiah 22:20–22 and Matthew 16:18–19 side by side. Ask students to list the parallels.
Discussion questions:
- Why would a Church meant to last until the end of time need an office that continues, not just one man?
- What is the difference between a bishop as a vicar of Christ and a bishop as the Pope’s branch manager?
Ecumenical note. Protestants usually read “this rock” as Peter’s faith or Christ himself, and the Orthodox accept a primacy of honour. Present the Catholic reading as an argument, and mention John Paul II’s invitation in Ut Unum Sint.
Misconceptions to watch for:
- “The Pope is always holy / always right.” Distinguish the office from the person, and infallibility from impeccability.
- “The Pope can change any teaching.” He is bound by the deposit of faith.
9.3 One, holy, catholic and apostolic
Goal: students can explain the four marks and how a Church of sinners is holy.
The abuse crisis. Students may raise it, and they should be able to. Acknowledge it honestly: these were grave crimes and betrayals, made worse by cover-ups. Do not minimise them or change the subject. The lesson’s point is that the Church’s holiness comes from Christ and the sacraments, not from its members’ record, and that sin in the Church is a betrayal of that holiness, not proof it was never there. If a student discloses personal harm, follow your school’s safeguarding procedures. The Apologetics section on Catholic Treasury has a fuller treatment of the crisis.
Discussion questions:
- Can something be holy if the people in it are not? Think of a hospital full of sick people.
- What do you share with Christians of other churches? What separates you?
Misconceptions to watch for:
- “Other Christians aren’t really Christians.” They are joined to Christ by Baptism.
- “‘Subsists in’ means the Catholic Church is just one church among many.” It means the Church of Christ is fully present in the Catholic Church.
9.4 “Outside the Church no salvation”
Goal: students can explain the teaching accurately, avoiding both “everyone else is damned” and “it doesn’t matter what you believe”.
How to teach it. State the teaching honestly first, then explain it. Avoid two mistakes: softening it until it means nothing, and presenting it as a verdict on the student’s non-Catholic friends and family. The positive rephrasing in CCC 846 (“all salvation comes from Christ through his Church”) and the situations table are the heart of the lesson.
Pastoral note. Many students have parents, grandparents or friends who are not Catholic, or not Christian. Make clear that the Church does not teach that such people are lost, and that judgement belongs to God, who wills all to be saved. Equally, do not imply that faith in Christ is unimportant.
Discussion questions:
- Why did St Cyprian first use this phrase? Does knowing the context change how you hear it?
- If people can be saved without knowing Christ, why would anyone become a missionary?
Misconceptions to watch for:
- “The Church changed its teaching at Vatican II.” The 1949 letter on the Feeney case predates the Council.
- “All religions are equally valid.” The Church rejects this too.
- “Being Catholic guarantees salvation.” Lumen Gentium 14: not without charity.
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 9.1: (1) Christ himself founded it. (2) Any two of: the Twelve; Peter as rock; “tell it to the Church”; the Eucharist; Pentecost. (3) Christ identifies the Church with himself. (4) Like Christ’s two natures in one Person: one reality, human and divine. (5) People of God, Body of Christ, Temple of the Holy Spirit.
Lesson 9.2: (1) Christ gave Peter a primacy of jurisdiction, and the Bishop of Rome succeeds him with full, supreme, universal power. (2) Any three of: Matthew 16:18–19; Luke 22:32; John 21:15–17; Matthew 10:2; Acts 1 and 15. (3) The chief steward holds the keys and governs in the king’s name, in a continuing office. (4) Clement’s letter to Corinth (about 96); Irenaeus’s list of Roman bishops (about 180). (5) No; they succeed the apostles, govern with their own authority, and form a college with the Pope.
Lesson 9.3: (1) One, holy, catholic, apostolic, as described in the table. (2) Holy in source, means, goal and saints, though always needing purification. (3) Fully present in the Catholic Church, with elements found outside. (4) The Church on earth is a mix of saints and sinners. (5) Its spread, holiness, fruitfulness, unity and stability.
Lesson 9.4: (1) All salvation comes from Christ through his Church. (2) Those who know the Church is necessary and refuse it. (3) A warning against leaving for a breakaway group. (4) Feeney taught all non-Catholics are damned; Rome rejected it in 1949. (5) The fullness of the means of salvation is in Christ and his Church, and people have a right to know him.
