    Main Branches and Denominations of Christianity

    Christianity is not a single uniform institution. It includes many branches, traditions, and denominations. While the details are complex, three broad historical categories are often used for educational purposes.

    Roman Catholicism

    Roman Catholicism is one of the largest Christian traditions in the world. It emphasizes church tradition, sacraments, the authority of the pope, and a global institutional structure.

    Eastern Orthodoxy

    Eastern Orthodox Christianity includes ancient churches known for liturgical worship, theological continuity, and strong connections to early Christian traditions and regional patriarchates.

    Protestantism

    Protestantism includes many denominations that emerged from the Reformation and later movements. These include Lutheran, Reformed, Anglican, Baptist, Methodist, Pentecostal, and many independent churches.

    Within each of these broad categories, there is significant diversity in theology, worship style, church structure, and social engagement. Christianity is best understood as a global family of related traditions.

    Open Bible representing Christian sacred texts

    The Bible is the central sacred text of Christianity and is used in worship, teaching, and devotion.

    The Bible and Christian Sacred Texts

    The Bible is Christianity’s primary sacred text and is divided into the Old Testament and the New Testament. The Old Testament overlaps in important ways with the Hebrew scriptures, while the New Testament focuses on Jesus, the early church, letters to Christian communities, and apocalyptic writings.

    Christians engage the Bible in different ways depending on tradition. It may be read devotionally, interpreted in formal liturgy, studied academically, preached publicly, or memorized in personal practice. Questions of translation, interpretation, and authority have played an important role in Christian history.

    Christianity Around the World

    Christianity is practiced on every inhabited continent and has taken root in a wide variety of languages, cultures, and social settings. In some countries, Christian identity is closely connected to national history. In others, Christian communities exist as minorities alongside other religious traditions.

    Global Christianity today includes ancient churches, established denominations, rapidly growing evangelical and Pentecostal movements, migrant congregations, small rural communities, and urban megachurches. This global diversity means that the lived experience of Christianity can differ greatly from one place to another.
