Eastern Orthodox ChurchThe Eastern Orthodox Church, also called the Orthodox Church and officially the Orthodox Catholic Church, is the second-largest Christian church, with approximately 220 million baptized members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the head of the Catholic Church—the pope—but the Ecumenical Patriarch of Constantinople is recognized by them as primus inter pares ("first among equals").
ChristianityChristianity (ˌkrɪstɪˈænɪti) is an Abrahamic monotheistic religion based on the life and teachings of Jesus of Nazareth. It is the world's largest and most widespread religion with roughly 2.4 billion followers representing one-third of the global population. Its adherents, known as Christians, are estimated to make up a majority of the population in 157 countries and territories, and believe that Jesus is the Son of God, whose coming as the Messiah was prophesied in the Hebrew Bible (called the Old Testament in Christianity) and chronicled in the New Testament.
ProtestantismProtestantism is a branch of Christianity that follows the theological tenets of the Protestant Reformation, a movement that began in the 16th century with the goal of reforming the Catholic Church from perceived errors, abuses, and discrepancies. Protestantism emphasizes the Christian believer's justification by God in faith alone (sola fide) rather than by a combination of faith with good works as in Catholicism; the teaching that salvation comes by divine grace or "unmerited favor" only (sola gratia); the priesthood of all believers in the Church; and the sola scriptura ("scripture alone") that posits the Bible as the sole infallible source of authority for Christian faith and practice.
Catholic ChurchThe Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.3 billion baptized Catholics worldwide It is among the world's oldest and largest international institutions, and has played a prominent role in the history and development of Western civilization. The church consists of 24 sui iuris churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies located around the world.
Church of EnglandThe Church of England (C of E) is the established Christian church in England. It traces its history to the Christian church recorded as existing in the Roman province of Britain by the 3rd century and to the 6th-century Gregorian mission to Kent led by Augustine of Canterbury. Its adherents are called Anglicans. The English church renounced papal authority in 1534 when Henry VIII failed to secure a papal annulment of his marriage to Catherine of Aragon.
PopeThe pope (papa, from πάππας), also known as the supreme pontiff (pontifex maximus or summus pontifex), Roman pontiff (Romanus pontifex) or sovereign pontiff, is the bishop of Rome (or historically the patriarch of Rome), head of the worldwide Catholic Church, and has also served as the head of state or sovereign of the Papal States and later the Vatican City State since the eighth century.
Middle AgesIn the history of Europe, the Middle Ages or medieval period (also spelled mediæval or mediaeval) lasted approximately from the late 5th to the late 15th centuries, aligning with the post-classical period of global history. It began with the fall of the Western Roman Empire in 476 AD and ended with the fall of Constantinople in 1453 AD before transitioning into the Renaissance and then the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: antiquity, medieval, and modern.
MethodismMethodism, also called the Methodist movement, is a group of historically related denominations of Protestant Christianity whose origins, doctrine and practice derive from the life and teachings of John Wesley. George Whitefield and John's brother Charles Wesley were also significant early leaders in the movement. They were named Methodists for "the methodical way in which they carried out their Christian faith". Methodism originated as a revival movement within Anglicanism originating out of the Church of England in the 18th century and became a separate denomination after Wesley's death.
ClergyClergy are formal leaders within established religions. Their roles and functions vary in different religious traditions, but usually involve presiding over specific rituals and teaching their religion's doctrines and practices. Some of the terms used for individual clergy are clergyman, clergywoman, clergyperson, churchman, ecclesiastic, and cleric, while clerk in holy orders has a long history but is rarely used.
EucharistThe Eucharist (ˈjuːkərɪst, ; from evcharistía, thanksgiving), also known as Holy Communion, the Blessed Sacrament and the Lord's Supper is a Christian rite that is considered a sacrament in most churches, and as an ordinance in others. Christians believe that the rite was instituted by Jesus at the Last Supper, the night before his crucifixion, giving his disciples bread and wine. Passages in the New Testament state that he commanded them to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the blood of my covenant, which is poured out for many".
PriestA priest is a religious leader authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the 'priesthood', a term which also may apply to such persons collectively.
Eastern OrthodoxyEastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Roman Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones.
New TestamentThe New Testament (NT) is the second division of the Christian biblical canon. It discusses the teachings and person of Jesus, as well as events in first-century Christianity. The New Testament's background, the first division of the Christian Bible, is called the Old Testament, which is based primarily upon the Hebrew Bible; together they are regarded as sacred scripture by Christians. The New Testament is a collection of Christian texts originally written in the Koine Greek language, at different times by various authors.
Saint PeterSaint Peter (died between AD 64 and 68), also known as Peter the Apostle, Simon Peter, Simeon, Simon, or Cephas ( () 'rock'), was one of the Twelve Apostles of Jesus Christ and one of the first leaders of the early Christian Church. He appears repeatedly and prominently in all four New Testament gospels as well as the Acts of the Apostles. According to Christian tradition, Peter was crucified in Rome under Emperor Nero.
EvangelicalismEvangelicalism (ˌiːvænˈdʒɛlɪkəlɪzəm,ˌɛvæn-,-ən-), also called evangelical Christianity or evangelical Protestantism, is a worldwide interdenominational movement within Protestant Christianity that affirms the centrality of being "born again", in which an individual experiences personal conversion; the authority of the Bible as God's revelation to humanity; and spreading the Christian message. The word evangelical comes from the Greek (euangelion) word for "good news".
Paul the ApostlePaul (also named Saul of Tarsus; 5-64/65 AD), commonly known as Paul the Apostle and Saint Paul, was a Christian apostle who spread the teachings of Jesus in the first-century world. Generally regarded as one of the most important figures of the Apostolic Age, he founded several Christian communities in Asia Minor and Europe from the mid-40s to the mid-50s AD. The main source of information on Paul's life and works is the Acts of the Apostles book in the New Testament, with approximately half of its content documenting them.
CalvinismCalvinism, also sometimes called the Reformed tradition, Reformed Protestantism, Reformed Christianity, or simply Reformed, is a major branch of Protestantism that follows the Christian theological tradition and forms of Christian practice set down by John Calvin and other Reformation-era theologians. It emphasizes the sovereignty of God and the authority of the Bible. Calvinists broke from the Roman Catholic Church in the 16th century.
DioceseIn church governance, a diocese ˈdaisis or bishopric is the ecclesiastical district under the jurisdiction of a bishop. Bishops and civil government In the later organization of the Roman Empire, the increasingly subdivided provinces were administratively associated in a larger unit, the diocese (Latin dioecesis, from the Greek term διοίκησις, meaning "administration"). Christianity was given legal status in 313 with the Edict of Milan. Churches began to organize themselves into dioceses based on the civil dioceses, not on the larger regional imperial districts.
