KS3 Religious Studies — Christianity Study Pack

Year group: 7–9 | Subject: Religious Studies / RE | Curriculum area: World Religions


Overview

Christianity is the world's largest religion, with over two billion followers across every continent. It grew from the life and teachings of Jesus of Nazareth, a Jewish teacher who lived in first-century Palestine. Christians believe Jesus was not only a great moral teacher but the Son of God — the second person of the Trinity — who died on the cross and rose from the dead, offering salvation to humanity. Christianity is remarkable for its diversity: it encompasses grand cathedrals and simple chapels, ancient rituals and contemporary praise worship, and communities ranging from rural England to urban Nigeria to South Korea. Despite this diversity, most Christians share core convictions about God, Jesus, the Bible, prayer, and the call to love others.

This study pack explores what Christians believe, how they worship, what their key texts and festivals are, and how their faith shapes ethical decision-making in everyday life. It also helps you understand the differences between denominations while recognising the shared foundations that unite Christians worldwide.


1. Core Beliefs and Teachings

1.1 Belief in God: The Trinity

Christians believe in one God — this is called monotheism. However, Christianity teaches a distinctive understanding of God as a Trinity: three persons in one God.

         GOD
        /    \
       /      \
  Father ——— Holy Spirit
       \      /
        \    /
          Son
        (Jesus)

All three are fully God; God is one.
  • God the Father: the creator of the universe; loving, just, and all-powerful
  • God the Son (Jesus Christ): God taking human form (the incarnation); teacher, healer, saviour
  • God the Holy Spirit: God's presence and power active in the world and in believers today

The Trinity is central to Christian worship. Christians baptise "in the name of the Father, Son and Holy Spirit" and say the Nicene Creed, which describes each person of the Trinity.

Pronunciation guide: Trinity = TRIN-ih-tee | Incarnation = in-kar-NAY-shun

1.2 Jesus: Son of God, Messiah, Teacher, Saviour

Christians believe Jesus was both fully human and fully divine — a mystery at the heart of their faith. Key events in Jesus's life include:

Event Meaning for Christians
Birth (Christmas) God enters human history; incarnation
Teaching and miracles Jesus reveals God's character and kingdom
Crucifixion Jesus dies to take the punishment for human sin; atonement
Resurrection (Easter) Jesus rises from death; death is conquered; salvation is real
Ascension Jesus returns to the Father; the Church is commissioned
Pentecost The Holy Spirit comes to empower the Church

Christians believe Jesus is the Messiah (Hebrew: anointed one / Christ in Greek) — the one promised in the Jewish scriptures who would restore the relationship between humanity and God.

1.3 Sin, Salvation and Grace

  • Sin: actions, attitudes or failures that break the relationship with God and others; Christians believe all humans fall short (Romans 3:23)
  • Salvation: being rescued from the consequences of sin and restored to a right relationship with God
  • Grace: God's undeserved love and gift; Christians believe salvation is a gift from God, not something earned
  • Forgiveness: central to Christian ethics — believers are called to forgive others as God forgives them

1.4 The Bible

The Bible is the sacred scripture of Christianity. It is not one book but a library of 66 books (Protestant) written over many centuries.

Section Contents
Old Testament (Hebrew Bible) Law, history, poetry (Psalms), prophecy — shared with Judaism
New Testament Four Gospels, Acts, Letters (epistles), Revelation
  • Gospels: accounts of Jesus's life and teaching (Matthew, Mark, Luke, John)
  • Parables: short stories Jesus used to teach about God and right living
  • Letters (epistles): teaching letters to early Christian communities, e.g. Paul's letters

Christians approach the Bible in different ways — some interpret it literally, others see much of it as symbolic or poetic while still inspired by God.


2. Worship and Practices

2.1 Prayer

Prayer is central to Christian life — speaking to and listening to God. Christians pray privately and collectively.

The Lord's Prayer (paraphrased in modern English):

Our Father in heaven, may your name be honoured. May your kingdom come, your will be done on earth as it is in heaven. Give us today what we need. Forgive us as we forgive others. Lead us away from temptation and deliver us from evil. The kingdom, power and glory are yours forever.

This prayer, taught by Jesus, covers praise, petition, forgiveness, and trust in God.

2.2 Church Services

A typical Sunday worship service might include:

  1. Singing hymns or worship songs
  2. Prayers (spoken aloud or in silence)
  3. Bible reading
  4. Sermon (a talk explaining and applying the Bible)
  5. Eucharist / Holy Communion / Mass (depending on denomination)
  6. Blessing and sending out

2.3 Sacraments

Sacraments are rituals that Christians believe convey God's grace. The two most widely accepted are:

Sacrament What it is Denominational variation
Baptism Water ritual marking entry into the Christian community Infants or adults; immersion or sprinkling
Eucharist (also: Holy Communion, Mass, Lord's Supper) Bread and wine remembering Jesus's death Catholics: transubstantiation; Protestants: various views

Catholics and Orthodox Christians recognise additional sacraments (confirmation, marriage, ordination, anointing of the sick, reconciliation/confession).

2.4 Denomination Comparison Grid

Feature Roman Catholic Eastern Orthodox Anglican Baptist
Leader Pope Patriarch Archbishop of Canterbury Local congregation
Eucharist view Bread/wine become body/blood (transubstantiation) Similar to Catholic Range of views Memorial only
Baptism Infant and adult Infant (immersion) Infant and adult Adults only (full immersion)
Worship style Formal liturgy, Latin or vernacular Formal liturgy, chanting Formal to informal Informal, preaching-centred
Saints Venerated; Mary highly honoured Venerated; Mary highly honoured Some commemoration Less emphasis
Scripture Bible + Tradition + Magisterium Bible + Holy Tradition Bible + tradition Bible only (sola scriptura)

3. Church: Building and Community

The word "church" has two meanings:

  1. A building used for worship — ranging from grand cathedrals like York Minster to simple meeting rooms
  2. The community of believers — all Christians everywhere, known as the "Body of Christ"
TYPICAL CHURCH LAYOUT (Protestant):
+—————————————————————————————+
|  Entrance / Narthex          |
|                               |
|   [Pews]   [Pews]            |
|   [Pews]   [Pews]            |  Nave
|   [Pews]   [Pews]            |
|                               |
|        [Pulpit]               |  Chancel
|        [Lectern]              |
|        [Altar/Table]          |
|                               |
+—————————————————————————————+

Key features:
- Font (near entrance): baptism
- Pulpit: preaching
- Lectern: Bible reading
- Altar/Table: Eucharist
- Cross or crucifix: central symbol
- Stained glass: Bible stories depicted

Clergy and laity: ordained ministers (priests, vicars, pastors) lead worship and pastoral care; the laity (all non-ordained members) serve through volunteering, giving, and outreach.


4. Key Texts and Source Extracts

Source Extract 1 — The Greatest Commandment

A teacher asked Jesus, "What is the most important commandment?" Jesus replied: "Love the Lord your God with all your heart, soul, mind and strength. The second is this: love your neighbour as yourself. There is no commandment greater than these." (Based on Mark 12:28–31)

Interpretation task: What does this teach about what Christians believe matters most in life? How might it influence a Christian's daily choices?

Source Extract 2 — The Good Samaritan (Parable Summary)

Jesus told a story of a man beaten and left on the road. A priest passed by, then a Temple official — both crossed to the other side. But a Samaritan (considered an outsider) stopped, bandaged his wounds, took him to an inn, and paid for his care. Jesus asked, "Which of these three was a neighbour?" The answer: the one who showed mercy. (Based on Luke 10:25–37)

Interpretation task: Why do you think Jesus used someone considered an outsider as the hero? What does this say about who counts as a "neighbour"?

Source Extract 3 — The Beatitudes (from the Sermon on the Mount)

"Blessed are the poor in spirit, for theirs is the kingdom of heaven. Blessed are those who mourn, for they will be comforted. Blessed are the peacemakers, for they will be called children of God. Blessed are those who hunger and thirst for justice, for they will be filled." (Based on Matthew 5:3–10)

Inference question: What values does Jesus seem to prioritise according to the Beatitudes? How might these surprise people who expect religion to be about following rules?

Source Extract 4 — The Resurrection

Early on Sunday morning, some women went to the tomb where Jesus had been buried. The stone had been rolled away. An angel said: "He is not here. He has risen, just as he said." They ran to tell the disciples, filled with fear and great joy. (Based on Matthew 28:1–8)

Discussion: Why do you think the resurrection is considered the most important event in the Christian story? What difference does it make if it happened?

Scenario — The Food Bank

St Andrew's Church opened its doors every Thursday morning. Volunteers sorted tinned food, fresh produce and basic toiletries. "We're not doing this to get people to church," said one volunteer. "We do it because Jesus told us to look after those who have nothing. It's that simple." The food bank served 200 families a week.

Ethical reasoning: How does this scenario show the connection between Christian belief and ethical action? Which teaching of Jesus does it reflect most clearly?


5. Christian Festivals and Calendar

CHRISTIAN YEAR TIMELINE:
|
|—— ADVENT (4 weeks before Christmas: waiting, preparation)
|
|—— CHRISTMAS (25 Dec): Birth of Jesus; incarnation
|
|—— EPIPHANY (6 Jan): Visit of the Magi; Jesus revealed to the nations
|
|—— ORDINARY TIME (weeks of teaching and growth)
|
|—— LENT (40 days before Easter: fasting, reflection, repentance)
|
|—— HOLY WEEK (Palm Sunday → Maundy Thursday → Good Friday)
|
|—— EASTER SUNDAY (resurrection): most important Christian festival
|
|—— ASCENSION (40 days after Easter)
|
|—— PENTECOST (50 days after Easter): coming of Holy Spirit
|
Festival Time of year Key meaning
Advent November/December Waiting and preparation for Jesus
Christmas 25 December Incarnation: God becomes human
Lent 40 days before Easter Fasting, reflection, turning back to God
Good Friday 2 days before Easter Crucifixion; death of Jesus
Easter Sunday Spring (varies) Resurrection; central Christian festival
Pentecost 50 days after Easter Holy Spirit; birth of the Church

Common misconception: Easter is not mainly about eggs and chocolate — these are cultural additions. The religious meaning is the resurrection of Jesus from the dead, which Christians consider the foundation of their faith.


6. Christian Symbols

Symbol Meaning
Cross Jesus's crucifixion and resurrection; central Christian symbol
Crucifix A cross with Jesus depicted on it; emphasises the sacrifice
Fish (Ichthys) Early Christian secret symbol; Greek letters stand for "Jesus Christ, Son of God, Saviour"
Candles The light of Christ in the world
Bread and wine Eucharist; the body and blood of Christ
Water Baptism; cleansing from sin; new life
Dove Holy Spirit; peace

7. Christian Ethics

7.1 Key Ethical Teachings

Christians base their ethics on:

  • The Bible: especially Jesus's teachings (Sermon on the Mount, parables)
  • The example of Jesus: especially his compassion, service, and sacrifice
  • The Church's tradition and guidance (different denominations vary here)
  • Conscience: the inner sense of right and wrong, guided by the Holy Spirit
  • Reason: thinking carefully about moral situations

7.2 Agape Love

Agape (Greek: AH-gah-pay) is the selfless, unconditional love Christians believe God shows to humanity and that Christians are called to show to others. It goes beyond feelings — it is a choice to seek the good of others regardless of how you feel.

7.3 Ethical Application Table

Ethical situation How Christian teaching may apply Example
Poverty Serve the poor; food banks; fair trade; Tearfund Matthew 25: "whatever you did for the least of these..."
Forgiveness Required even when hard; mirrors God's forgiveness Lord's Prayer; story of the Prodigal Son
Conflict Seek peace; some support just war; some are pacifists "Blessed are the peacemakers"
Injustice Speak up; campaign for fairness Christian Aid; Martin Luther King Jr
Environment God's creation; stewards of the earth Genesis 1–2; Eco-Church movement

9. Common Misconceptions

Misconception Correction
All Christians worship in exactly the same way Christianity has enormous diversity — a Catholic Mass and a Pentecostal praise service look very different, yet both are genuine Christian worship
The Trinity means Christians believe in three separate gods No: Christians believe in one God who is three persons — a mystery, not a contradiction. The Trinity is one God in three distinct relationships
The Bible is one book written at one time by one person The Bible is a library of 66 books, written over roughly 1,500 years by many different authors in different genres
Christianity is mainly European or British Christianity originated in the Middle East. Today it has more followers in Africa, Latin America and Asia than in Europe
A church is just a building "Church" means the community of believers. The earliest Christians met in homes. The building is a venue, not the Church itself
Easter is mainly about eggs and chocolate These are cultural additions. Easter celebrates the resurrection of Jesus, which Christians consider the most important event in history
All Christians interpret every moral issue identically Christians disagree on many ethical questions — they hold a range of views on war, capital punishment, social issues, and politics, all informed by their shared faith

  1. What is the name given to Jesus's followers in the New Testament? (Disciples / Apostles)
  2. Name one sacrament accepted by most Christian denominations. (Baptism or Eucharist)
  3. What does the term "denomination" mean in Christianity? (A branch or tradition within Christianity)

4-Mark Questions

Question: Explain two ways in which belief in the resurrection may influence how Christians live their lives.

Model answer:

Firstly, Christians who believe in the resurrection may face death and suffering with hope rather than despair. Because they believe Jesus conquered death, they trust that their own lives do not end permanently at death. This may give them courage when facing illness, bereavement or persecution.

Secondly, belief in the resurrection may motivate Christians to serve others sacrificially, just as Jesus gave his life for others. They may volunteer in food banks, campaign against injustice, or support people in need, believing that following Jesus's example is the right response to what he did for them.


Question: Explain two differences in how Christians from different denominations practise baptism.

Model answer:

One difference is the age at which baptism is performed. Catholics and Anglicans often baptise infants, believing this brings the child into the Christian community and forgives original sin. Baptists, however, only baptise adults or older teenagers who can make their own commitment to follow Jesus.

A second difference is the method. Anglicans and Catholics typically sprinkle water on the person's head, while Baptist churches practise full immersion — the person is fully submerged in water. Baptists believe this better symbolises dying to an old life and rising to a new one, echoing Jesus's death and resurrection.


Extended Writing Questions

Question: "The most important Christian belief is the resurrection." How far do you agree?

Points to consider:

  • The resurrection is unique to Christianity and different from all other faiths
  • Paul wrote "if Christ has not been raised, your faith is useless" (1 Corinthians 15)
  • Without resurrection, there is no salvation or hope beyond death
  • However, some may argue the Trinity defines Christianity's understanding of God
  • Others might prioritise the incarnation — God entering human experience
  • Some may say Jesus's ethical teachings (love your neighbour) are most important for daily life

Model answer structure (for students to build on):

Some people would agree that the resurrection is the most important Christian belief because... [give 2 reasons with evidence]

However, others might argue that... [give alternative view with evidence]

On balance, I think... [state a judgement supported by reasoning]


Source Interpretation

Source: "We gather every Sunday not because we have to, but because we want to — to remember what Jesus did, to thank God, to be together, and to be sent back out to love the world better. The bread and wine help us feel close to Jesus even though he isn't here physically." (Primary school teacher, Church of England)

Questions:

  1. Identify two reasons this person gives for attending church. (To remember Jesus; to thank God; to be with others; to be sent out to love — any two)
  2. What does the bread and wine represent to this person? (They help feel close to Jesus; a memorial of his death)
  3. Suggest how a Catholic and a Baptist might see the bread and wine differently. (Catholic: bread and wine become the actual body and blood of Jesus; Baptist: they are symbols of remembrance only)
