Early Christianity: The movement and communities centered on Jesus that arose in the first century CE. The Catholic Church emerged from the diverse communities and traditions of early Christianity.
Papacy: The office and institutional authority of the pope, head of the Catholic Church. The papacy became the Church’s central office of leadership and a recurring source of conflict.
East–West Schism: The gradual separation between the Catholic Church in the West and the Eastern Orthodox churches, conventionally dated to 1054. The rupture ended a millennium of increasingly strained relations between eastern and western Christianity.
Protestant Reformation: A sixteenth-century movement that challenged papal authority and produced enduring Protestant churches. It prompted Catholic responses that reshaped doctrine, worship, and Church discipline.
Catholic social teaching: A body of Catholic principles addressing social, economic, and political life, including human dignity and solidarity. Its modern development connects Church history to debates about labor, poverty, and justice.
Paul the Apostle: An early Christian missionary and letter-writer whose work shaped the spread and theology of Christianity. His missions and letters helped establish communities beyond the Jewish world.
Ecumenical council: A gathering of bishops that addresses matters of doctrine, discipline, or Church governance across the Christian world. Councils formalized teachings and governance during major turning points.
Avignon Papacy: The period from 1309 to 1377 when popes resided in Avignon rather than Rome. The papacy’s residence in France weakened its standing and preceded a major leadership crisis.
Catholic missions: Organized efforts to spread Catholic Christianity through preaching, education, and church-building. Missionary activity expanded Catholic communities while entangling the Church with colonial power.
Liberation theology: A Christian theological movement that interprets faith through the struggle against poverty and oppression, especially in Latin America. It reflects the tensions between Catholic teaching, social inequality, and political change.
