Today Christianity is considered the world's largest religious faith, with around 2.2 billion followers. But Christianity is by no means a monolithic faith. Instead Christians are divided into a variety of denominations and sects-Roman or orthodox, Catholic or Protestant, Evangelical or Pentecostal, to name a few examples. All Christian sects share a belief in the divinity of Jesus Christ, who Christians believe came to Earth to redeem humanity. This book provides the history of Christianity, and explains how the current divisions in the faith occurred. It also provides information about the beliefs shared by most Christians, details the major sects, and explores festivals and holy days. The Major World Religions series provides information about six of the most important religious faiths practiced around the world. More than 75 percent of the world's population-over 5.2 billion people-observes the tenets of one of these six religions. Each book in the series describes the important beliefs of a particular religion, along with information about its history, practices, and rituals.
