What are Christianity's holy books?

The Bible (also known as the Holy Bible) is the Christian holy book. It is divided into the Old and New Testaments. Parts of the writing contained in the Old Testament are also sacred to Jewish and Muslim people.

Types of Christian Faith

There are different branches of Christianity because some Christians worship in different ways. Click on the links below to find out more about the different branches of Christianity.

What is the Holy Trinity?

The Trinity is a central concept of Christianity. It is the idea that God is one but exists in three different ‘persons’ - God the Father, the Son and the Holy Spirit - and that these three persons form a unity.

What is Christianity?

Christianity is the world's biggest religion, with about 2.2 billion followers worldwide. It is based on the teachings of Jesus Christ, who Christians believe to be the Son of God. Jesus was born in Bethlehem in the Middle East over 2,000 years ago. 

Christians believe there is only one God, but that he is revealed in three different forms:

  • God the Father
  • God the Son (Jesus)
  • The Holy Spirit

Christians believe that God sent Jesus to live as a human being in order to save humanity from the consequences of its sins - the bad things humanity had chosen to do which had separated them from God. Christians believe that through the death and resurrection of Jesus this broken relationship with God is restored.

Who is the founder of Christianity?

Jesus Christ, who was born 2000 years ago in Bethlehem, is the founder of Christianity. Nearly all that is known about Jesus comes from the Bible, in the four Gospels of the New Testament. According to the Bible, Jesus Christ is the Son of God. He came to earth to teach about love and fellowship. He represents the person that all Christians must strive to be. Jesus lived for 33 years before being crucified by the Romans  around A.D. 30 in Jerusalem. Christians believe that Jesus rose from the dead and appeared to his disciples (followers) to show everyone that there is another life with one, eternal, loving God.

Where do Christians worship?

Christians meet to worship together in a church. Depending on the number of people that are in a community, the churches come in different sizes. Small churches are called chapels. A catheral is a very big church and is usually run by a Bishop.

Christian Festivals

There are two major holidays celebrated by Christians around the world:

Easter is the most important festival in the Christian calendar. It celebrates Jesus rising from the dead on Easter Sunday, three days after he was executed by crucifixion on Good Friday. The date of Easter Sunday varies from year to year. It is celebrated on the first Sunday after the full moon, on or after 21 March. For Christians, Easter eggs are used as a symbol for the resurrection of Jesus because an egg is a symbol of new life. 

Christmas is celebrated each year on 25 December to mark the birth of Jesus. Christians celebrate Christmas by carol singing and retelling the story of Jesus's birth in nativity plays. Some Christians start Christmas Day with a midnight mass or communion service. Families and friends will get together to have Christmas dinners eating traditional foods such as turkey, mince pies and Christmas puddings.
