The term "Western Christianity" does not have a direct reference in the Bible, as the concept primarily emerged in the context of historical, cultural, and theological developments after the biblical texts were written. However, Western Christianity generally refers to the branch of Christianity that developed in Western Europe, characterized by certain theological emphases, liturgical practices, and ecclesiastical structures, particularly after the Great Schism in 1054 which divided Christianity into Western (Roman Catholic) and Eastern (Orthodox) branches.In biblical terms, the foundation for what would later influence Western Christianity can be found in the New Testament, particularly in the missionary activities of Paul, who is often seen as a pivotal figure in spreading the gospel to Gentile (non-Jewish) communities across the Roman Empire, including regions that would become part of Western Europe (Acts 13-28). The teachings found in the Epistles, such as those to the Romans and Corinthians, shaped early Western theological thought. Over the centuries, the interpretation and application of these biblical teachings evolved, leading to distinct expressions of faith that characterize Western Christianity today, including the development of doctrines such as original sin, the nature of salvation, and the authority of the Church, which were articulated by church fathers and later theologians such as Augustine and Aquinas.
