Origins & Early Life

The Catholic Church (Latin: Ecclesia Catholica), also called the Roman Catholic Church (Latin: Ecclesia Catholica Romana), is the largest Christian church, with an estimated 1.28 to 1.41 billion baptized members worldwide as of 2026. It consists of 24 autonomous (sui iuris) churches. The largest one of these churches is the Latin Church. In addition to it, there are 23 smaller Eastern Catholic Churches. Together, the Latin Church and the Eastern Catholic churches are organized into nearly 3,500 dioceses and eparchies governed by bishops.

Career & Major Achievements

Throughout history, the church has had a large role in the development of Western civilization. Catholic communities are present worldwide through missions, immigration, and conversions. The majority of Catholics live in the Global South, reflecting rapid demographic growth in Africa, Asia, and Latin America, as well as secularization in parts of Europe and North America. Catholic doctrine is rooted in the Nicene Creed and holds that the church is the "one, holy, catholic and apostolic Church" founded by Jesus Christ. It teaches that bishops are the successors of the apostles and that the pope—the bishop of Rome—is the successor of Saint Peter the Apostle, entrusted with a unique and primary pastoral role.

Enduring Legacy & Impact

Leo XIV is the current pope, serving as the head of the church; the Diocese of Rome forms his local jurisdiction, while the Holy See serves as the church's central governing authority through the Roman Curia. Apostolic teaching is understood to be transmitted through Scripture and sacred tradition, interpreted by the magisterium, the church's teaching authority. Catholic liturgical life includes the Roman Rite, other rites of the Latin Church, and the liturgical traditions of the Eastern Catholic Churches. Religious orders, monastic communities, and lay movements contribute to a wide range of theological and devotional expressions within Catholicism globally. Among the church's seven sacraments, the Eucharist is seen as the source and summit of the Christian life and is celebrated in the Mass.
