Apostolic succession is the method whereby the ministry of the Christian Church is considered by some Christian denominations to be derived from the apostles by a continuous succession, which has usually been associated with a claim that the succession is through a series of bishops. Those of the Catholic, Eastern Orthodox, Scandinavian Lutheran, Anglican, Oriental Orthodox, Church of the East, Hussite, Moravian, and Old Catholic traditions maintain that "a bishop cannot have regular or valid orders unless he has been consecrated in this apostolic succession". These traditions do not always consider the episcopal consecrations of all of the other traditions as valid.
A creed, also known as a confession of faith, a symbol, or a statement of faith, is a statement of the shared beliefs of a community which summarize its core tenets.
The word catholic comes from the Greek phrase καθόλου 'on the whole, according to the whole, in general', and is a combination of the Greek words κατά 'about' and ὅλος 'whole'. The first known use of "Catholic" was by the church father Saint Ignatius of Antioch in his Letter to the Smyrnaeans. In the context of Christian ecclesiology, it has a rich history and several usages.
An episcopal polity is a hierarchical form of church governance in which the chief local authorities are called bishops. The word "bishop" here is derived via the British Latin and Vulgar Latin term *ebiscopus/*biscopus, from the Ancient Greek ἐπίσκοπος epískopos meaning "overseer". It is the structure used by many of the major Christian Churches and denominations, such as the Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East, Anabaptist, Lutheran, and Anglican churches or denominations, and other churches founded independently from these lineages. Many Methodist denominations have a form of episcopal polity known as connexionalism.
The Nicene Creed, also called the Creed of Constantinople, is the defining statement of belief of Nicene Christianity and in those Christian denominations that adhere to it.
Sola scriptura is a Christian theological doctrine held by most Protestant Christian denominations, in particular the Lutheran and Reformed traditions, that posits the Bible as the sole infallible source of authority for Christian faith and practice. The Catholic Church considers it heresy and generally the Orthodox churches consider it to be contrary to the phronema of the Church.
In ecclesiology, the Christian Church is what different Christian denominations conceive of as being the true body of Christians or the original institution established by Jesus Christ. "Christian Church" has also been used in academia as a synonym for Christianity, despite the fact that it is composed of multiple churches or denominations, many of which hold a doctrinal claim of being the one true church to the exclusion of the others.
A Christian denomination is a distinct religious body within Christianity that comprises all church congregations of the same kind, identifiable by traits such as a name, particular history, organization, leadership, theological doctrine, worship style and, sometimes, a founder. It is a secular and neutral term, generally used to denote any established Christian church. Unlike a cult or sect, a denomination is usually seen as part of the Christian religious mainstream. Most Christian denominations refer to themselves as churches, whereas some newer ones tend to interchangeably use the terms churches, assemblies, fellowships, etc. Divisions between one group and another are defined by authority and doctrine; issues such as the nature of Jesus, the authority of apostolic succession, biblical hermeneutics, theology, ecclesiology, eschatology, and papal primacy may separate one denomination from another. Groups of denominations—often sharing broadly similar beliefs, practices, and historical ties—are sometimes known as "branches of Christianity". These branches differ in many ways, especially through differences in practices and belief.
Christian tradition is a collection of traditions consisting of practices or beliefs associated with Christianity. Many churches have traditional practices, such as particular patterns of worship or rites, that developed over time. Deviations from such patterns are sometimes considered unacceptable by followers, or are regarded as heretical. There are certain Christian traditions that are practiced throughout the liturgical year, such as praying a daily devotional during Advent, erecting a nativity scene during Christmastide, chalking the door on Epiphany Day, fasting during Lent, waving palms on Palm Sunday, eating easter eggs during Eastertide, and decorating the church in red on Pentecost.
Confessional Lutheranism is a name used by Lutherans to designate those who believe in the doctrines taught in the Book of Concord of 1580 in their entirety. Confessional Lutherans maintain that faithfulness to the Book of Concord, which is a summary of the teachings found in Scripture, requires attention to how that faith is actually being preached, taught, and put into practice. Confessional Lutherans believe that this is a vital part of their identity as Lutherans.
Sacred tradition, also called holy tradition or apostolic tradition, is a theological term used in Christian theology. According to this theological position, sacred Tradition and Scripture form one deposit, so sacred Tradition is a foundation of the doctrinal and spiritual authority of Christianity and of the Bible. Thus, the Bible must be interpreted within the context of sacred Tradition and within the community of the denomination. The denominations that ascribe to this position are the Catholic, Eastern Orthodox, and Oriental Orthodox churches, and the Assyrian churches.
The term Evangelical Catholic is used in Lutheranism, alongside the terms Augsburg Catholic or Augustana Catholic, with those calling themselves Evangelical Catholic Lutherans or Lutherans of Evangelical Catholic churchmanship stressing the catholicity of historic Lutheranism in liturgy, beliefs, practices, and doctrines. Evangelical Catholics teach that Lutheranism at its core "is deeply and fundamentally catholic". The majority of Evangelical Catholic Lutheran clergy and parishes are members of mainstream Lutheran denominations.
Catholicity is a concept pertaining to beliefs and practices that are widely accepted by numerous Christian denominations, most notably by those Christian denominations that describe themselves as catholic in accordance with the Four Marks of the Church, as expressed in the Nicene Creed formulated at the First Council of Constantinople in 381: "[I believe] in one, holy, catholic, and apostolic Church." The English adjective catholic is derived from the Ancient Greek adjective καθολικός, meaning "general", "universal". Thus, "catholic" means that in the Church the wholeness of the Christian faith, full and complete, all-embracing, and with nothing lacking, is proclaimed to all people without excluding any part of the faith or any class or group of people. An early definition for what is "catholic" was summarized in what is known as the Vincentian Canon in the 5th century Commonitory: "what has been believed everywhere, always, and by all."
Anglican doctrine is the body of Christian teachings used to guide the religious and moral practices of Anglicanism.
Catholic theology is the understanding of Catholic doctrine or teachings, and results from the studies of theologians. It is based on canonical scripture, and sacred tradition, as interpreted authoritatively by the magisterium of the Catholic Church. This article serves as an introduction to various topics in Catholic theology, with links to where fuller coverage is found.
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, the Christian Churches/Churches of Christ, the Latter Day Saint movement, the Churches of Christ, 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.
Confirmation in the Lutheran Church is a public profession of faith prepared for by long and careful instruction. In English, it may also be referred to as "affirmation of baptism", and is a mature and public reaffirmation of the faith which "marks the completion of the congregation's program of confirmation ministry".
Lutheranism is a major branch of Protestantism that identifies primarily with the theology of Martin Luther, the 16th-century German monk and reformer whose efforts to reform the theology and practices of the Catholic Church launched the Reformation in 1517. Lutheranism subsequently became the state religion of many parts of Northern Europe, starting with Prussia in 1525.
Criticism of Protestantism covers critiques and questions raised about Protestantism, the Christian denominations which arose out of the Protestant Reformation. While critics may praise some aspects of Protestantism which are not unique to the various forms of Protestantism, Protestantism is faced with criticism mainly from the Catholic Church and the Eastern Orthodox Church, although Protestant denominations have also engaged in self-critique and criticized one another. According to both the Catholic Church and Eastern Orthodoxy, many major, foundational Protestant doctrines have been officially declared heretical.
