Christianity stems from the life, teachings, death, and resurrection of Jesus of Nazareth, which are narrated in the New Testament of the Bible. Millions of Christians worldwide re-enact an important episode in Jesus' life, the Last Supper, as a part of worship. Christianity encompasses both the Protestant and Catholic religions.
