Christian churches are made up of many different denominations and beliefs. The basis of all Christian churches is that Jesus is the son of God, God having become man on earth, and our saviour. Christian churches teach the Bible - both the Old Testament and the New Testament as the living word of God. The three largest groups of Christian church denominations are the Roman Catholic Church, Eastern Orthodox churches, and the various denominations of Protestantism.
