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.
Christian theologyChristian theology is the theology of Christian belief and practice. Such study concentrates primarily upon the texts of the Old Testament and of the New Testament, as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument.
Latin ChurchThe Latin Church (Ecclesia Latina) is the largest autonomous (sui iuris) particular church within the Catholic Church, whose members constitute the vast majority of the 1.3 billion Christians in communion with the Pope in Rome. The Latin Church is one of 24 churches sui iuris in communion with the pope; the other 23 are referred to as the Eastern Catholic Churches, and have approximately 18 million members combined. The Latin Church is directly headed by the Pope in his role as the Bishop of Rome, whose cathedra as a bishop is located in the Archbasilica of Saint John Lateran in Rome, Italy.
Reformation_The Reformation The Reformation (alternatively named the Protestant Reformation, and the European Reformation) was a major movement in Western Christianity in 16th-century Europe that posed a religious and political challenge to the Catholic Church and in part, it also posed a challenge to papal authority. The Reformation marked the start of Protestantism and in the Western Church, the Latin Church, remained the Catholic Church. It is considered one of the events that signified the end of the Middle Ages and the beginning of the early modern period in Europe.
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.
TrinityThe Christian doctrine of the Trinity (Trinitas, from trinus 'threefold') is the central doctrine concerning the nature of God in most Christian churches, which defines one God existing in three , , consubstantial divine persons: God the Father, God the Son (Jesus Christ) and God the Holy Spirit, three distinct persons (hypostases) sharing one essence/substance/nature (homoousion) As the Fourth Lateran Council declared, it is the Father who s, the Son who is , and the Holy Spirit who proceeds.
God the FatherGod the Father is a title given to God in Christianity. In mainstream trinitarian Christianity, God the Father is regarded as the first person of the Trinity, followed by the second person, God the Son Jesus Christ, and the third person, God the Holy Spirit. Since the second century, Christian creeds included affirmation of belief in "God the Father (Almighty)", primarily in his capacity as "Father and creator of the universe".
Church FathersThe Church Fathers, Early Church Fathers, Christian Fathers, or Fathers of the Church were ancient and influential Christian theologians and writers who established the intellectual and doctrinal foundations of Christianity. The historical period in which they worked became known as the Patristic Era and spans approximately from the late 1st to mid-8th centuries, flourishing in particular during the 4th and 5th centuries, when Christianity was in the process of establishing itself as the state church of the Roman Empire.
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.
Athanasian CreedThe Athanasian Creed — also called the Pseudo-Athanasian Creed or Quicunque Vult (or Quicumque Vult), which is both its Latin name and its opening words, meaning "Whosoever wishes" — is a Christian statement of belief focused on Trinitarian doctrine and Christology. Used by Christian churches since the early sixth century, it was the first creed to explicitly state the equality of the three hypostases of the Trinity.
