Christianity is the religion with the most followers in the world; almost a third of the world’s population are Christians.

Like Jews and Muslims, Christians believe in just one God who created the world and all that is in it.

Christians follow the teachings of Jesus Christ, a preacher and healer who lived in the Middle East more than 2000 years ago. Christians believe that Jesus was the Son of God, sent down to earth to save people by dying on the cross and taking the punishment for their sins. It is through looking at Jesus’s life and example that Christians believe they can learn what God is like.

Did you know?

Christians celebrate Jesus’s birth every year on 25th December – Christmas Day – but no one knows exactly when he was born. The first Christians did not celebrate Jesus’s birth.

At the age of 30, Jesus travelled all over his country teaching others about God, encouraging people to love and respect each other. He became known for healing sick people and performing miracles; perhaps the most famous was when he was said to have fed five thousand people with just five loaves and two fish! Jesus always attracted large crowds of people whenever he came to talk and he told many stories to teach people about God, but the religious leaders of the time did not like what he had to say.

Christians think that God can be seen in three ways, which is known as the Holy Trinity:

  • God the Father, who created and cares for the world and everything in it.
  • God the Son, who came down to earth as Jesus.
  • God the Holy Spirit, which symbolises God’s power living within Christians.

The Bible is the holy book of Christians. The Christian Bible contains the Old Testament and the New Testament. The Old Testament contains the same books as the Jewish Bible (although Christians have a different view of what is written down) and was written before Jesus’s birth. The New Testament contains stories about Jesus written by people who met him or had heard of him.

Sunday is a time when most Christians meet to worship God, whether in a church, a hall or someone's house.

A church can be big, small, old, new, plain or highly decorated. You will find that the floor plan of many churches is in the shape of a cross.

Church services usually include prayers, hymns and readings from the Bible.

Christians believe that praying to God allows them to say sorry for the things they have done wrong and thank you for their blessings, to pray for other people (for example, for healing) and to pray for his help and strength for themselves. Christians believe that God wants them to be like Jesus Christ and carry on the good work he did in the world.

All Christians share common beliefs but there are different branches of Christianity. These include:

  • The Church of England (the officially established Christian church in England)
  • The Roman Catholic Church (which is headed by the Pope)
  • Baptists
  • Methodists
  • Presbyterians
  • Quakers

  • The Eucharist

  • Cologne Cathedral seen from the air (showing the cross-shaped structure)

Christians believe that Jesus was the son of God. He was born to Jewish parents, Mary and Joseph, in Bethlehem in Roman-occupied Judea. This all happened over 2000 years ago.

The reason we celebrate Christmas is because Christians celebrate Jesus’s birth on 25 December, although his exact birthday is not really known. It is thought that Christians chose the darkest and coldest time of year to highlight the ‘light’ Jesus brought to the world.

There is very little written about Jesus as a child, but at the age of 30 he travelled for three years teaching people about God and healing the sick. Wherever Jesus went, people came to listen to him and to ask for his help. He seemed to have a special interest in the sick and the poor.

Jesus chose 12 men to travel with him and be his special companions; they became knows as his disciples.

Jesus went to Jerusalem with his disciples during the Jewish Passover festival. It was there that he was arrested and sentenced to death. Jesus’s crime was calling himself the Son of God, he was thought to be treating God’s name with disrespect. This is known as blasphemy.

Jesus shared a final meal with his disciples where he tried to warn them about what was going to happen to him. This became known as The Last Supper. Jesus shared around bread and wine; the bread was to symbolise his body and the wine his blood.

Jesus was crucified, which meant he was nailed to a wooden cross and left to die. The cross is a very important Christian symbol: it reminds Christians of how and why Jesus died.

Jesus was buried in a tomb but three days later, the tomb was found empty. This is known as the resurrection, which means Jesus had risen from the dead. Jesus is believed to have appeared before his disciples before finally going up to heaven to be reunited with God. His journey into heaven is known as the ascension.

Christians believe that Jesus sacrificed or gave up his own life in order to save all those who followed and believed in him. By dying on the cross, he took the ‘punishment’ people deserve for the things they have done wrong and made them pure and blameless in the eyes of God.

It is through looking at Jesus’s life and example that Christians believe they can learn what God is like.

Christians believe that God is kind and loving and is always ready to forgive people for doing wrong as long as they are truly sorry and promise to follow God. It is the belief of many Christians that when they die, they will go to heaven to be with God and Jesus.

The Eucharist is the main religious ritual in many churches. The word means thanksgiving and during the service bread and wine are shared, just as they were in the Last Supper.

People are welcomed into the Christian faith by a baptism ceremony, sometimes when they are a baby (a time to promise God that the baby will be brought up as a Christian) and sometimes when they are an adult (and make the promises for themselves).

The two main Christian festivals are Easter and Christmas. Christmas is when Christians celebrate the birth of Jesus. Easter marks the death and resurrection of Jesus and is the most important Christian festival.
