Catholicity
Concept of universal Christian faith and church unity.
Catholicity (from Ancient Greek: καθολικός, romanized: katholikós, meaning 'general', 'universal') is a concept pertaining to beliefs and practices widely accepted by numerous Christian denominations, most notably those that describe themselves as catholic in accordance with the Four Marks of the Church as expressed in the Nicene Creed. The term signifies that in the Church the wholeness of the Christian faith, full and complete, is proclaimed to all people without excluding any part of the faith or any class or group. An early definition was summarized in the Vincentian Canon: 'what has been believed everywhere, always, and by all.'

Lore & Background
Catholicity is distinct from the capitalized word Catholic, which refers specifically to the Catholic Church, often the Roman Catholic Church, used especially in ecumenical contexts. Though the community led by the pope in Rome is known as the Catholic Church, the traits of catholicity are also ascribed to denominations such as the Eastern Orthodox Church, the Oriental Orthodox Church, and the Assyrian Church of the East. It also occurs in the language of churches that split from the Roman Catholic Church, like Lutheranism and Anglicanism, as well as Independent Catholicism and Old Catholicism.
Reader's Guide
The concept of catholicity has been central to Christian self-identity and ecumenical dialogue, serving as a marker of continuity with the early church founded by Jesus Christ. Major schisms—such as those following the Councils of Ephesus (431) and Chalcedon (451), the East–West Schism (1054), and the Protestant Reformation—have each involved disputes over which groups authentically embody catholicity. The theory of Pentarchy and the role of the bishop of Rome as 'first among equals' illustrate early organizational structures. In modern contexts, catholicity is invoked by diverse denominations to claim apostolic faith and universal scope, while the capitalized term Catholicism specifically denotes the communion of churches in union with the pope. The term remains contested, with different groups emphasizing varying attributes such as sacraments, episcopal polity, apostolic succession, and liturgical worship.
