Christianity, major religion stemming from the life, teachings, and death of Jesus of Nazareth (the Christ, or the Anointed One of God) in the 1st century CE. It has become the largest of the world’s religions and, geographically, the most widely diffused of all faiths. It has a constituency of more than two billion believers. Its largest groups are the Roman Catholic Church, the Eastern Orthodox churches, and the Protestant churches. The Oriental Orthodox churches constitute one of the oldest branches of the tradition but had been out of contact with Western Christianity and Eastern Orthodoxy from the middle of the 5th century until the late 20th century because of a dispute over Christology (the doctrine of Jesus Christ’s nature and significance). Significant movements within the broader Christian world and sometimes transcending denominational boundaries are Pentecostalism, Charismatic Christianity, Evangelicalism, and fundamentalism. In addition, there are numerous independent churches throughout the world.
