Get the information you need on the topic of Christianity. According to the Pew Research Center, as of 2015, Christianity is the world religion with the most followers globally. Christianity is one of three primary monotheistic faiths, a religion that believes in one God, along with Judaism and Islam.

There are three primary branches of Christianity: Eastern Orthodox Christianity, Roman Catholicism, and Protestantism. There are many denominations, or subgroups, within these branches, including Baptist, Methodism, Lutheranism, Calvinism, Pentecostalism, Anglicanism, Presbyterianism, and Adventism. Christians can also be grouped more broadly across denominations according to their style of worship or focus of their beliefs. For example, the term evangelicals describes Christians who focus on the importance of a salvation experience (sometimes referred to as being “born again” or “being saved”) and spreading the gospel to non-Christians.

Christianity began in the first century CE when followers of the Jewish teacher known as Jesus of Nazareth, in the area of present-day Israel, began to teach that Jesus was the Christ, or Messiah. Jesus’ disciples preached that he was the one described in the books of prophecy as the Son of God who would die to atone for the sins of the world.

The foundational belief of Christianity is that Jesus Christ was crucified and then rose from the dead three days later, an event commemorated in the observance of Easter. The Christian Bible—which is a collection of ancient Hebrew writings, Jesus’ teachings as compiled by his disciples, and letters written by church leaders known as apostles to various early churches and individuals—is the source of Christian beliefs.

A wide range of materials are available, whether one is seeking to research Christian history and the historical Jesus or discover modern guides to living the faith. Scholars, Bible study members, people considering a role in ministry, and students of religious studies will benefit from the material offered. Those who want to learn more about Catholic, Protestant, and Eastern Orthodox traditions will find relevant texts for historical study. Followers of Christ who are looking for information on subject areas such as discipleship and prayer will find resources to enhance their personal spiritual enrichment.

Gale offers a wealth of sources that explore topics including the New Testament, the Reformation, the Church Fathers, Christian life, and the diversity of World Christianity. Many will recognize such varied figures as Flavius Josephus, Athanasius, John Wesley, Watchman Nee, Origen, and Polycarp. Users will find scholarly journals, monographs, eBooks, peer-reviewed articles, and primary sources on a vast array of subjects within the study of the Christian tradition.

Christian groups, like those from other faiths, are leveraging modern tools to reach their followers. The COVID-19 pandemic has elevated the role of databases not only for educational purposes but also for religious expression. Church services, sermons, and devotions have moved online and are becoming more common across denominations. Ministering to the community, taking part in biblical studies, and holding prayer groups can all take place on the internet.

  • Flawed Church, Faithful God: A Reformed Ecclesiology for the Real World

    Flawed Church, Faithful God: A Reformed Ecclesiology for the Real World

    Wm. B. Eerdmans Publishing Company   |   2018   |   ISBN-13: 9781467450638

    How can we reconcile the ideal church described by theology with the broken church that we see in the world? This book argues that the church's true identity is known somewhere in the tension between the two. It revisits familiar ecclesiological concepts—people of God, the body of Christ, the communion of the Holy Spirit—but rather than focusing on theological abstractions or worldly cynicism, it carefully evaluates the church in its scriptural, historical, theological, and social contexts. Both sociologically honest and theologically discerning, this title offers a constructive Reformed, yet ecumenical ecclesiology for the real world.

  • Remembrance, Communion, and Hope: Rediscovering the Gospel at the Lord's Table

    Remembrance, Communion, and Hope: Rediscovering the Gospel at the Lord's Table

    Wm. B. Eerdmans Publishing Company   |   2018   |   ISBN-13: 9781467449403

    In this book, the author shows how a renewed theology and practice of the Lord's Supper can lead Christians to rediscover the full richness and depth of the gospel. With an eye for helping congregations move beyond common reductions of the gospel, he develops a vibrant, biblical, and distinctly Reformed sacramental theology and explores how it might apply within a variety of church contexts, from Baptist to Presbyterian, nondenominational to Anglican.

  • Sacred Sense: Discovering the Wonder of God's Word and World

    Sacred Sense: Discovering the Wonder of God's Word and World

    Wm. B. Eerdmans Publishing Company   |   2019   |   ISBN-13: 9781467452601

    How can we make sense of violence in the Bible? Joshua commands the people of Israel to wipe out everyone in the promised land of Canaan, while Jesus commands God's people to love their enemies. How are we to interpret biblical passages on violence when it is sanctioned at one point and condemned at another? This book presents a new framework, solidly rooted in the authority of scripture, for understanding the paradox of God's participation in violence. It shows how the historical narrative of the Bible offers multiple canonical pictures for faithful Christian engagement with the violent systems of the world.
