Christianity revolves around core beliefs about salvation, Jesus Christ, and... Show more

Sin is anything that separates humans from God, and Christians believe we all have original sin - a built-in tendency to do wrong inherited from Adam and Eve. This might sound heavy, but Christianity offers hope through Jesus.
Salvation means being saved from sin and its consequences. Christians believe this happens through grace (God's free gift) and faith in Jesus. There's debate about whether good works are also needed - some say faith alone is enough (Ephesians 2:8), whilst others argue "faith by itself, if not accompanied by action, is dead" (James 2:17).
Atonement is how Jesus fixed the broken relationship between God and humanity. By dying on the cross, Jesus took on all human sins and paid the debt for them. His death and resurrection made eternal life possible for everyone who believes.
Remember: Jesus said "I am the way and the truth and the life. No one comes to the Father except through me" (John 14:6) - this shows how central Jesus is to Christian salvation.
When Christians die, they believe they'll face judgement based on their faith in Jesus and how they lived. The Parable of the Sheep and Goats teaches that serving others is like serving Jesus himself.
Heaven is eternal happiness in God's presence, whilst Hell is eternal suffering without God. Christians disagree about who gets into heaven - some say only Christians, others include good people from other religions, and some say only baptised Christians.
Catholics believe in Purgatory, where souls are cleansed before entering heaven. All Christians believe in resurrection - that they'll get new bodies for eternal life, though they debate whether this happens immediately after death or when Jesus returns to Earth.

The Holy Trinity is one of Christianity's most important beliefs - that God exists as three persons (Father, Son, Holy Spirit) who are all God but not each other. It's mind-bending but central to Christian faith, as stated in the Nicene Creed.
The Incarnation means God became human in Jesus. "The word became flesh and made his dwelling among us" (John 1:14). This made God relatable whilst remaining fully divine - Jesus was 100% God and 100% human simultaneously.
Jesus's crucifixion wasn't just an execution - it was God experiencing human pain and death. After three days, Jesus resurrected and spent 40 days with his disciples before ascending to heaven, promising they'd continue his work.
Key Point: The resurrection proves that death isn't the end and gives Christians confidence they'll have an afterlife too.
Christians believe in one God (monotheism) with four main characteristics: omnipotent , omniscient , omnibenevolent , and omnipresent (everywhere). God is also transcendent - beyond our physical world.
Creation happened when God made everything in six days and rested on the seventh. "Let there be light and there was light" shows God's power through words alone. The Holy Spirit was active during creation, "hovering over the waters."
However, Mackie's inconsistent triad challenges these beliefs - if God is all-powerful, all-knowing, and all-loving, why does evil exist? This remains a major theological question Christians wrestle with.
Christians trust in God as creator and believe everything God made was originally good - suffering entered through human sin, not God's design.
