​Christianity is the largest and longest established of the world religious traditions observed in the UK. Christians believe that there is one God who has been revealed as the Creator, Sustainer and Redeemer of all and they believe that God’s nature is revealed in the life, teaching, death and resurrection of Jesus of Nazareth. Christians believe in the incarnation (the birth of Jesus), that God fully identified with humanity. Christians believe that God’s healing and saving activity is fully demonstrated in the life and teaching of Jesus. In its various forms Christianity has shaped the past and present life of the British Isles including its legal structures and public institutions. This section includes both trinitarian Christian churches and churches that relate to or derive from Christianity.
