Catholicity in the context of "Evangelical Catholic"

Eastern Orthodox theology is the theology particular to the Eastern Orthodox Church. It is characterized by monotheistic Trinitarianism, belief in the Incarnation of the divine Logos or only-begotten Son of God, cataphatic theology with apophatic theology, a hermeneutic defined by a sacred Tradition, a catholic ecclesiology, a theology of the person, and a principally recapitulative and therapeutic soteriology.

The expression "one true church" refers to an ecclesiological position asserting that Jesus gave his authority in the Great Commission solely to a particular visible Christian institutional church—what is commonly called a denomination. This view is maintained by the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox communion, the Assyrian Church of the East, the Ancient Church of the East, and the Lutheran churches, as well as certain Baptists. Each of them maintains that their own specific institutional church (denomination) exclusively represents the one and only original church. The claim to the title of the "one true church" relates to the first of the Four Marks of the Church mentioned in the Nicene Creed: "one, holy, catholic, and apostolic church". As such, it also relates to claims of both catholicity and apostolic succession: asserting inheritance of the spiritual, ecclesiastical and sacramental authority and responsibility that Jesus Christ gave to the apostles.

The concept of schism somewhat moderates the competing claims between some churches—one can potentially repair schism, since they are striving for the same goal. For example, the Catholic and Eastern Orthodox churches each regard the other as schismatic and at very least heterodox, if not heretical, yet both have held dialogues and even partaken in Councils in attempts to resolve the division that exists between them.

High church Lutheranism is a movement that began in 20th-century Europe and emphasizes worship practices and doctrines that emphasize the sacraments and liturgy, along with a robust devotional life. In the more general usage of the term, it describes the general high church characteristics of Lutheranism in Nordic and Baltic countries such as Sweden, Finland, Estonia and Latvia. The mentioned countries have more markedly preserved pre-Reformation, Catholic traditions and eschewed Reformed theology. From the earliest part of its development, Lutheranism as a whole has employed elaborate liturgies and ornate sacred art. Lutheranism has viewed its faith and practice as "deeply and fundamentally catholic". It is closely related to the concept of Evangelical Catholicism, which emphasizes the catholicity of Lutheranism.

The Malankara Mar Thoma Syrian Church, often shortened to Mar Thoma Church, and known also as the Reformed Syrian Church and the Mar Thoma Syrian Church of Malabar, is an autonomous Oriental Protestant Christian church based in Kerala, India. While continuing many of the Syriac high church practices, the church is Protestant in its theology and doctrines. It employs a reformed variant of the West Syriac Rite Divine Liturgy of Saint James, translated to Malayalam.

The Mar Thoma Church sees itself as continuation of the Saint Thomas Christians, a community traditionally believed to have been founded in the first century by Thomas the Apostle, who is known as Mar Thoma (Saint Thomas) in Syriac, and describes itself as "Apostolic in origin, Universal in nature, Biblical in faith, Evangelical in principle, Ecumenical in outlook, Oriental in worship, Democratic in function, and Episcopal in character".

The Church of Ireland (Irish: Eaglais na hÉireann, pronounced [ˈaɡlˠəʃ n̪ˠə ˈheːɾʲən̪ˠ]; Ulster-Scots: Kirk o Airlann, [kɪrk ə ˈerlən(d)]) is a Christian church in Ireland, and an autonomous member church of the Anglican Communion. It is organised on an all-Ireland basis and is the second-largest Christian church on the island after the Roman Catholic Church. Like other Anglican churches, it has retained elements of pre-Reformation practice, notably its episcopal polity, while rejecting the primacy of the pope.

In theological and liturgical matters, it incorporates many principles of the Reformation, particularly those of the English Reformation, but self-identifies as being both Reformed and Catholic, in that it sees itself as the inheritor of a continuous tradition going back to the founding of Christianity in Ireland. As with other members of the global Anglican Communion, individual parishes accommodate differing approaches to the level of ritual and formality, variously referred to as High and Low Church.

The independent sacramental movement (ISM) is a loose collection of individuals and Christian denominations that are not part of the historic sacramental Christian denominations embodying catholicity (such as the Catholic Church, Eastern Orthodox Church, the Scandinavian Lutheran churches and Anglican churches) and yet continue to practice the historic sacramental rites independently.

The term was used in 2005 by John Plummer, in The Many Paths of the Independent Sacramental Movement, and was used earlier, in 2002, by Richard Smoley in his Inner Christianity.
