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. The photograph above is a microscopic view of the spice Myrrh, a symbol of the Christian religion and a representative of the valuable gifts the Magi brought to the baby Jesus in Bethlehem. As part of the lucrative spice trade, myrrh, a bitter gum tree resin and commodity, played an important role in sacrifices and other religious ceremonies.
