Teacher Notes: Unit 1, How Theology Works
Why this unit comes first
Unit 1 gives students the tools for everything else: where Catholic teaching comes from, who has authority to teach it, what faith is, and how to tell dogma from opinion. Students who skip it tend to treat every statement in later units as equally certain, or equally optional.
The unit is more abstract than the rest of the course. Keep it concrete by returning often to one or two worked examples. The Trinity at Nicaea and the Immaculate Conception in 1854 serve well across all five lessons.
By the end of the unit, students should be able to:
- explain the difference between natural knowledge of God and supernatural revelation;
- describe how Scripture, Tradition and the Magisterium relate;
- state when the Pope and bishops teach infallibly, and when they do not;
- distinguish divine faith from human trust and from feeling;
- define a dogma and use the four theological notes to label a teaching.

Lesson by lesson
1.1 What is revelation?
Goal: students can explain why revelation is needed even though reason can know God.
Discussion questions:
- If a friend wanted you to know what they really think of you, could you work it out just by watching them? What would you need them to do? (This leads into revelation as God speaking, not just God being observed.)
- Why might God choose to reveal truths that reason could have found anyway?
Misconceptions to watch for:
- “Private revelations are part of the faith.” Students with a devotion to Fatima or Divine Mercy may be surprised. Make clear that the Church approves such revelations as worthy of belief and helpful, without making them binding.
- “Revelation means God dictated the Bible.” This is addressed in Lesson 1.2; flag it here.
1.2 Scripture and Tradition
Goal: students can explain why Catholics hold both Scripture and Tradition, using the canon as an example.
Discussion questions:
- Before the New Testament was written, how did the first Christians know what to believe?
- Can you prove from the Bible alone which books belong in the Bible?
Misconceptions to watch for:
- “Tradition means old customs.” Use the capital-T, small-t distinction early.
- “Catholics aren’t supposed to read the Bible.” Some students will have heard this; correct it directly.
- “Inerrancy means everything is literal.” Point ahead to Unit 4 on Genesis.
Sensitivity: some students will have Protestant family members or friends. Present the Catholic position as an argument to be understood, not as a put-down of other Christians, who share the Scriptures and much of the Tradition.
1.3 The Magisterium
Goal: students can state the conditions for an infallible teaching and give examples of what is not infallible.
Discussion questions:
- Why might Christ have given his Church living teachers instead of only a book?
- How is infallibility different from being always right about everything?
Misconceptions to watch for:
- “Infallible means sinless.” This is the most common confusion.
- “Everything the Pope says is infallible”, or its mirror image, “Catholics only have to accept infallible teachings.” Lesson 1.5 deals with the second; mention it here.
1.4 Faith
Goal: students can define faith and explain how it differs from feeling, guessing, and human trust.
Discussion questions:
- List ten things you believe on someone else’s word. Is that unreasonable?
- Can someone be certain of something they cannot see?
Misconceptions to watch for:
- “Faith is believing without evidence.” Distinguish the evidence that it is reasonable to believe (the motives of credibility) from evidence that shows the mystery itself (which we do not have).
- “If I have doubts, I’ve lost my faith.” Use Newman’s distinction between difficulties and doubts. Some students will be relieved by this; handle it pastorally.
1.5 Dogma and how sure we are
Goal: students can define a dogma, explain development without reversal, and label teachings with the four notes.
Discussion questions:
- Is a tree in winter the same tree as in summer? How is that like doctrine?
- Can you think of something the Church has changed? Was it a dogma?
Activity: the sorting exercise. Give students ten statements to label de fide, certain, common teaching, opinion, or not Church teaching. The list of de fide teachings and its last section, on things often mistaken for dogma, supply plenty of material. Expect disagreement; the discussion is the point.
Misconceptions to watch for:
- “The Church changes with the times.” Separate dogma from discipline.
- “If it isn’t infallible, I don’t have to accept it.” Introduce the three levels of assent from the 1989 Profession of Faith.
Answer key
The answers to every Check your understanding question appear on the lesson pages, hidden behind Show answer. If you set them as written work, ask students to answer before opening the answers.
Lesson 1.1: (1) Reason from created things; supernatural revelation. (2) So all can know it easily, firmly and without error. (3) A truth we could not discover and cannot fully comprehend; the Trinity or the Incarnation. (4) Public revelation is complete; no private revelation binds Catholics. (5) In Christ God speaks through his own Son, and can say nothing greater.
Lesson 1.2: (1) Written books and unwritten traditions. (2) 2 Thessalonians 2:15 or 2 Timothy 2:2. (3) The Bible does not list its own books; the canon is known through the Church’s reception. (4) No; the human authors were true authors, with their own styles and literary forms. (5) Tradition hands on revelation and cannot change; traditions are changeable customs.
Lesson 1.3: (1) “Teacher”; the Pope and the bishops in communion with him. (2) As shepherd of all Christians, with supreme authority, defining faith or morals, to be held by the whole Church. (3) The Spirit guards and explains what the apostles handed on; he does not reveal new doctrine. (4) Not ex cathedra, and not faith or morals. (5) Extraordinary: solemn definitions such as Nicaea or 1854. Ordinary: everyday teaching, infallible when bishops worldwide agree on something as definitive.
Lesson 1.4: (1) Believing what God has revealed because of his authority, by grace. (2) Human faith rests on a human witness and natural powers; divine faith rests on God and needs grace. (3) Grace moves the will, which freely inclines the mind; the evidence does not force assent. (4) Signs that make belief reasonable, without proving the mysteries or producing faith by themselves. (5) Difficulties are not doubts.
Lesson 1.5: (1) Revealed by God, and proposed by the Church as revealed. (2) Growth like a body from childhood to age: same person, same meaning. (3) A new word expressing what was always believed. (4) De fide; common teaching; opinion. (5) Some truths are more central; none can be dropped.
