Christianity: beliefs and teachings
The nature of God, the Trinity, creation, Jesus, salvation and the afterlife — the beliefs that every theme paper then applies.
Christians do not worship three gods. They worship one God known in three persons.
The important bits
What you need to know
- 1
Christians are monotheists. God is believed to be omnipotent, omnibenevolent, just, omniscient and eternal. The problem of evil (how a good, powerful God permits suffering) is the standing challenge to those attributes.
- 2
The Trinity: Father, Son and Holy Spirit as three persons, one God. Baptismal formula (Matthew 28:19) and the Nicene tradition guard this against both tritheism and the idea that Jesus was merely a prophet.
- 3
Creation: Genesis 1 (ordered days, humans in God’s image) and Genesis 2 (Adam from the soil, Eve from his side, Garden). Literal, liberal and theistic-evolution readings all appear in classrooms; the shared claim is that the universe is willed, not accidental, and that humans have a special status and duty.
- 4
Incarnation: Jesus is fully God and fully human (John 1:14). This underpins why his death can be more than a tragic execution.
- 5
Crucifixion, resurrection and ascension are a sequence: Jesus dies (atonement), is raised (victory over death, 1 Corinthians 15), and returns to the Father (promise of the Spirit and of judgement). Different churches weight the Cross as sacrifice, victory, or moral example.
- 6
Salvation is rescue from sin and death. Catholic emphasis often includes sacraments and cooperation with grace; many Protestants emphasise justification by faith. Grace means the initiative is God’s, not a wage the human earns.
- 7
Sin includes acts against God and neighbour; some traditions teach original sin (humanity wounded from the start). Forgiveness is possible because of the Cross and, for many, through repentance, baptism and a changed life.
- 8
Afterlife: bodily resurrection, judgement, heaven, and (in traditional teaching) hell. Some Christians are annihilationist or universalist; know the mainstream exam answers first, then a diversity sentence.
Quotations worth analysing
Short evidence. Real method.
“So God created mankind in his own image.”
Imago Dei is the Christian root of human dignity. It drives arguments about the sanctity of life, equality, and why murder and exploitation are theological as well as social wrongs.
“The Word became flesh and made his dwelling among us.”
Incarnation: God does not stay distant. Jesus’ humanity makes his suffering real; his divinity makes that suffering salvific in orthodox teaching.
“For God so loved the world that he gave his one and only Son.”
Links omnipotent love to the Cross. Use it in salvation, incarnation, and “God is omnibenevolent” questions rather than as a floating slogan.

Why the Trinity is not a maths fail
Year 10 jokes about 1+1+1=3 miss the doctrine. Christians claim one divine essence and three persons who are not three parts of a pie. The Father creates and sends, the Son is begotten and incarnate, the Spirit proceeds and gives life to the Church. Modalism (one God wearing three masks) and Arianism (Jesus as a junior creature) were rejected because they cannot carry worship of Jesus or the baptismal name. In a 5-mark “explain” question, give the formula, one biblical hook (Matthew 28:19 or the baptism of Jesus), and one reason it matters: prayer, Eucharist, and the claim that God is relational in himself, not lonely then needy for humans.

Atonement without one-word answers
“Jesus died for our sins” is true in Christian teaching and too thin for 12 marks. Churches tell that death differently. Penal substitution (common in evangelical Protestantism) says Jesus bears the penalty justice required. Christus Victor says the Cross breaks the power of sin, death and the devil. Moral-influence views say the Cross reveals love that should convert us. Catholic teaching holds a sacrificial and sacramental account bound to the Mass. You do not need every label, but you need two Christian ways and a reason a Christian might prefer one. Then tie it to resurrection: a dead Messiah with no rising is, for Paul, a failed gospel (1 Corinthians 15).

Creation, science and the exam’s real demand
GCSE is not a creationist rally. It asks whether Genesis and cosmology can coexist. Conservative Christians may read six days as history and see evolution as a threat to biblical authority. Others read Genesis as theology (who and why, not laboratory how) and accept the Big Bang and evolution as describing the secondary causes God uses. Catholic official teaching allows evolutionary theory if the soul is not reduced to matter. The smart 12-mark move is: both sides care about truth; they disagree whether scripture is a science text. Bring imago Dei back so the question stays about the value of humans, not a playground fight about dinosaurs.
See the idea in action
Question: explain two Christian beliefs about the afterlife. Belief 1: bodily resurrection, Jesus as “firstfruits” (1 Corinthians 15), so death is not the end of the person. Belief 2: judgement, with heaven as eternal life with God. Develop each with a teaching and a consequence (funerals, hope in suffering, moral seriousness). If the question asks for contrasting views, add a minority universalist hope that all are saved, and say why most exam-board mark schemes still expect heaven/hell as the main line.
Exam technique
Turn knowledge into marks
Always name the person of the Trinity you mean. “God died on the cross” will irritate some markers; “the Son became incarnate and was crucified” is precise.
Common mistakes
Do not give these marks away
- 01
Writing as if Christians are polytheists, or as if the Trinity is three gods who get along.
- 02
Stopping at “Jesus died for our sins” with no link to resurrection, grace or different atonement emphases.
- 03
Treating every Christian as a six-day literalist, or every Christian as uninterested in scripture.
What do Christians mean by the Trinity?
AThree separate gods who cooperate
BOne God in three persons: Father, Son and Holy Spirit
CThat Jesus was a prophet but not divine
DThat God only exists during church services
Show the answer
One God in three persons: Father, Son and Holy Spirit. Monotheism is preserved: one God. The three persons are not masks or parts. This is why Christians can pray to the Father, through the Son, in the Spirit without counting three deities.
Quick questions
If this is the bit you searched
Do all Christians interpret Genesis literally?
No. Some do. Many read it as a theological text about God, purpose and human dignity, and accept scientific accounts of how the universe and life developed. The exam wants that diversity named.
What is grace?
God’s free, undeserved help. In Protestant slogans, salvation is by grace through faith, not by collecting moral wages. Catholic teaching also calls grace essential, working through sacraments and a transformed life.
