Christianity: Key Beliefs

Christians believe in one God who is the creator and sustainer of everything that exists. Three attributes are central to Christian understanding of God's nature:

Attribute	Meaning	Biblical basis
Omnipotent	All-powerful; can do anything that is logically possible	Genesis 1 — God creates the universe by speaking it into existence
Loving	Agape — unconditional, self-giving love	1 John 4:8 — "God is love"
Just	Righteous judge; evil is ultimately punished, good rewarded	Psalms — God as defender of the poor and upholder of justice

The problem of evil and suffering arises from holding all three attributes simultaneously: if God is omnipotent, God could prevent evil; if God is loving, God would want to; yet evil exists. Different Christian responses include:

• Free will defence: God grants humans freedom; suffering results from misuse of that freedom (moral evil). God allows this because love cannot be coerced.
• Soul-making theodicy: suffering enables spiritual growth and the development of virtues (natural evil). The world is not meant to be comfortable but a place of moral development.
• Accepting mystery: some suffering remains inexplicable; Christians are called to trust God's purposes even when they cannot understand them (the Book of Job).

No single response to the problem of evil is universally accepted by all Christians, and the question remains a serious challenge to theistic belief.

Christians believe in one God who exists as three persons: Father, Son and Holy Spirit. This is the doctrine of the Trinity.

The Trinity is not three gods (polytheism) nor three modes of one God (modalism): each person is distinct, yet the three are one in essence, will and being. The doctrine was formally defined at the Council of Nicaea (325 CE) and expressed in the Nicene Creed.

The three persons and their roles:

Person	Role	Key association
Father	Creator and sustainer; eternal source	"Our Father in heaven" (Lord's Prayer)
Son	Incarnate in Jesus; redeemer	John 3:16 — God so loved the world he gave his Son
Holy Spirit	Comforter, guide, sanctifier; present in the Church and believers	Acts 2 — descent at Pentecost

The Father, Son and Holy Spirit are co-equal and co-eternal — no person is subordinate to another. Christians worship one God, not three. The Trinity is described as a "mystery" — something that can be believed and experienced but not fully comprehended by human reason.

Different denominations emphasise different aspects: Orthodox Christianity stresses the eternal procession of persons; Protestant Christianity typically focuses on the personal relationship with God the Father through Christ.

Christian belief in creation draws on two key biblical passages:

"In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made." — John 1:1–3

"In the beginning God created the heavens and the earth. Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. And God said, 'Let there be light,' and there was light." — Genesis 1:1–3

Together these passages identify the Word (Logos — understood by Christians as the pre-incarnate Son) and the Spirit as active in creation alongside the Father.

Contrasting Christian interpretations:

View	Description	Who holds it
Literal creationism	Genesis 1 describes six 24-hour days of creation; the earth is relatively young	Some Evangelical and Fundamentalist Christians
Day-age creationism	"Days" in Genesis 1 represent long ages; compatible with an old earth	Many Conservative Christians
Theistic evolution	God created through the process of evolution; Genesis conveys theological truth, not scientific mechanism	Many mainstream Protestant and Catholic Christians
Liberal / allegorical	Genesis 1 is poetry expressing God as creator; scientific accounts of origins are not in conflict with faith	Many Liberal Christians

What all views share: God is the ultimate origin of everything; creation is good and reflects God's wisdom; humanity has a special relationship with God as image-bearers (imago Dei).

Christian belief in life after death is grounded in the resurrection of Jesus, understood as the model and guarantee of believers' own resurrection.

Resurrection: Christians believe the body will be raised at the end of time — not as the physical body is now, but transformed. This contrasts with the Greek idea of the immortality of the soul (the soul escaping the body). Most Christians believe in the resurrection of the body, though interpretations of what this means vary.

Judgement: At death — or at the end of time (eschatological judgement) — each person faces divine judgement. Actions, faith, and responses to others are assessed. Matthew 25 (the Sheep and Goats) presents judgement based on how people treated the hungry, the stranger, the sick.

Heaven: The eternal presence of God — described in different ways: a place, a state, a relationship. Revelation 21 describes a new creation, the New Jerusalem, where God dwells with humanity and "he will wipe every tear from their eyes."

Hell: Separation from God — either eternal conscious suffering (traditional view) or annihilation (conditionalism). Some Christians (universalists) believe all will ultimately be reconciled to God.

Different Christians hold different views about the nature of heaven and hell. What is consistent is the belief that how one lives in this life matters for eternity.

The resurrection of Jesus is the foundation: if Christ is risen, Paul argues in 1 Corinthians 15, then the dead will also be raised.

Incarnation Christians believe that the eternal Son of God became fully human in Jesus of Nazareth — fully God and fully human, two natures in one person. This belief is called the Incarnation (incarnatus — "made flesh"). John 1:14: "The Word became flesh and made his dwelling among us." Jesus' birth to the Virgin Mary, announced by the angel Gabriel, is described in Luke 1–2 and Matthew 1. The Incarnation means that God enters human experience — suffering, temptation, death — from the inside.

Crucifixion Jesus was executed by crucifixion under the Roman governor Pontius Pilate, around 30 CE. Christians believe this was not merely a tragic execution but the means by which God dealt with sin. The cross stands at the centre of Christian faith.

Resurrection Three days after his death, Jesus rose bodily from the dead — the empty tomb and appearances to his disciples are described in all four Gospels. The resurrection is the vindication of Jesus' life and teaching and the foundation of Christian hope.

Ascension Forty days after the resurrection, Jesus ascended into heaven and was seated at the right hand of the Father (Acts 1; the Apostles' Creed). This marks the completion of his earthly mission and his return to divine glory.

These four events form the core of Christian belief and are confessed in the creeds recited by Christians across denominations.

Sin Sin is any thought, word or action that falls short of God's standards — a turning away from God and toward the self or created things instead. Christians distinguish between:

• Original sin: the belief (associated especially with Augustine and Catholic/Protestant traditions) that the sin of Adam and Eve introduced a condition of disordered desire and separation from God that affects all humanity. Human beings are born into a state of fallenness, not moral perfection.
• Actual sin: specific choices and actions that fall short of God's will.

Salvation Christians believe salvation — being saved from sin, its consequences and eternal separation from God — comes through Jesus Christ. Three means are emphasised in the spec:

Means	Description
Law	The moral law (commandments) shows what God requires and reveals human inability to achieve it alone
Grace	God's unmerited favour — salvation as gift, not earned (Ephesians 2:8–9: "it is by grace you have been saved, through faith")
Spirit	The Holy Spirit transforms believers from within, making them capable of living as God intends

Atonement — how Christ's death deals with sin — has been interpreted in different ways:

• Substitution/penal substitution: Christ takes the punishment that humanity deserves (common in Evangelical Protestantism)
• Moral influence: Christ's death demonstrates God's love and draws humans to repentance (common in Liberal Christianity)
• Christus Victor: Christ defeats the powers of sin, death and evil through the cross and resurrection (common in Orthodox Christianity)

1. Describing the Trinity as three separate gods

The Trinity is one God in three persons — not three gods. This distinction is foundational. A 6-mark answer should use precise language: "Christians believe in one God who exists as three persons."

2. Confusing creation texts

John 1:1–3 focuses on the Word (Logos); Genesis 1:1–3 focuses on God speaking and the Spirit hovering. Both are required for questions on Christian beliefs about creation. Citing only Genesis misses the Johannine perspective.

3. Treating resurrection and immortality of the soul as the same

Christian belief emphasises bodily resurrection — the body is raised and transformed, not discarded. "The soul goes to heaven when you die" is closer to Greek philosophy than mainstream Christian doctrine, though views vary across denominations.

4. Using only one view on salvation/atonement

A 12-mark question on salvation or atonement requires at least two contrasting Christian views — not just one tradition's account. Substitution, moral influence and Christus Victor are the three main models to know.

5. Forgetting original sin is contested

Original sin is held by Catholic and many Protestant traditions but is interpreted differently across denominations — some Liberal Christians understand it metaphorically rather than as a literal inherited condition. A strong 12-mark answer acknowledges this diversity.
