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.
Brethren of the Free SpiritThe Brethren of the Free Spirit were adherents of a loose set of beliefs deemed heretical by the Catholic Church but held (or at least believed to be held) by some Christians, especially in the Low Countries, Germany, France, Bohemia, and Northern Italy between the thirteenth and fifteenth centuries. The movement was first identified in the late thirteenth century. It was not a single movement or school of thought, and it caused great unease among Church leaders at the time. Adherents were also called Free Spirits.
AtheismAtheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists. The first individuals to identify themselves as atheists lived in the 18th century during the Age of Enlightenment.
Papal infallibilityPapal infallibility is a dogma of the Catholic Church which states that, in virtue of the promise of Jesus to Peter, the Pope when he speaks ex cathedra is preserved from the possibility of error on doctrine "initially given to the apostolic Church and handed down in Scripture and tradition". It does not mean that the pope cannot sin or otherwise err in most situations. This doctrine, defined dogmatically at the First Vatican Council of 1869–1870 in the document Pastor aeternus, is claimed to have existed in medieval theology and to have been the majority opinion at the time of the Counter-Reformation.
Medieval InquisitionThe Medieval Inquisition was a series of Inquisitions (Catholic Church bodies charged with suppressing heresy) from around 1184, including the Episcopal Inquisition (1184–1230s) and later the Papal Inquisition (1230s). The Medieval Inquisition was established in response to movements considered apostate or heretical to Roman Catholicism, in particular Catharism and Waldensians in Southern France and Northern Italy. These were the first movements of many inquisitions that would follow.
Catholic theologyCatholic 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. Major teachings of the Catholic Church discussed in the early councils of the church are summarized in various creeds, especially the Nicene (Nicene-Constantinopolitan) Creed and the Apostles' Creed.
MonothelitismMonothelitism, or monotheletism (from monothelētismós), is a theological doctrine in Christianity, that holds Christ as having only one will. The doctrine is thus contrary to dyothelitism, a Christological doctrine that holds Christ as having two wills (divine and human). Historically, monothelitism was closely related to monoenergism, a theological doctrine that holds Jesus Christ as having only one Energeia/Nature. Both doctrines were at the center of Christological disputes during the 7th century.
History of ChristianityThe history of Christianity concerns the Christian religion, Christian countries, and the Christians with their various denominations, from the 1st century to the present. Christianity originated with the ministry of Jesus, a Jewish teacher and healer who proclaimed the imminent Kingdom of God and was crucified AD 30–33 in Jerusalem in the Roman province of Judea. His followers believe that, according to the Gospels, he was the Son of God and that he died for the forgiveness of sins and was raised from the dead and exalted by God, and will return soon at the inception of God's kingdom.
Christian views on sinIn Christianity, 'sin' is an immoral act considered to be a transgression of divine law. The doctrine of sin is central to the Christian faith, since its basic message is about redemption in Christ. Hamartiology, a branch of Christian theology which is the study of sin, describes sin as an act of offence against God by despising his persons and Christian biblical law, and by injuring others. Christian hamartiology is closely related to concepts of natural law, moral theology and Christian ethics.
First seven ecumenical councilsIn the history of Christianity, the first seven ecumenical councils include the following: the First Council of Nicaea in 325, the First Council of Constantinople in 381, the Council of Ephesus in 431, the Council of Chalcedon in 451, the Second Council of Constantinople in 553, the Third Council of Constantinople from 680–681 and finally, the Second Council of Nicaea in 787. All of the seven councils were convened in modern-day Turkey. These seven events represented an attempt by Church leaders to reach an orthodox consensus, restore peace and develop a unified Christendom.
