Christianity is the largest world religion, with over 1 billion followers worldwide. There are more than 6 million practising Christians in the UK, and a total of 35 million people in Britain consider themselves to be Christians.
This religion originated in Palestine two thousand years ago and is based on the teachings and life of Jesus Christ. The 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.
The New Testament explains how God sent his only son, Jesus Christ, to restore the broken relationship between human kind and God which had been caused by man's wrong doing. Jesus was executed on a cross as a criminal by the Romans, and according to Christian teaching afterwards rose from the dead before ascending to heaven.
Christians worship in churches and their leaders are known as priests or ministers. Christians believe that God is revealed in three different forms: the Father, Son and Holy Spirit. Christians model themselves on the life and teachings of Jesus Christ. For instance, many churches hold a service called Communion, or Eucharist, in which bread and wine are shared together, just as Jesus did with his followers before his death.
The most important Christian festivals are: Lent, Easter and Christmas. As a result of differing interpretations of Christian scripture, different denominations have sprung up, including the Church of England, the Roman Catholic Church, the Eastern Orthodox Church and many others.
