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.
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.
Penal substitutionPenal substitution (sometimes, esp. in older writings, called forensic theory) is a theory of the atonement within Protestant Christian theology, which declares that Christ, voluntarily submitting to God the Father's plan, was punished (penalized) in the place of sinners (substitution), thus satisfying the demands of justice so God can justly forgive sins making us at one with God (atonement). It began with the German Reformation leader Martin Luther and continued to develop within the Calvinist tradition as a specific understanding of substitutionary atonement.
Anselm of CanterburyAnselm of Canterbury OSB (ˈænsɛlm; 1033/4–1109), also called Anselm of Aosta (Anselmo d'Aosta) after his birthplace and Anselm of Bec (Anselme du Bec) after his monastery, was an Italian Benedictine monk, abbot, philosopher and theologian of the Catholic Church, who held the office of Archbishop of Canterbury from 1093 to 1109. After his death, he was canonized as a saint; his feast day is 21 April. As archbishop, he defended the church's interests in England amid the Investiture Controversy.
Ransom theory of atonementThe ransom theory of atonement was a theory in Christian theology as to how the process of Atonement in Christianity had happened. It therefore accounted for the meaning and effect of the death of Jesus Christ. It was one of a number of historical theories, and was mostly popular between the 4th and 11th centuries, with little support in recent times. It originated in the early Church, particularly in the work of Origen.
Substitutionary atonementSubstitutionary atonement, also called vicarious atonement, is a central concept within Western Christian theology which asserts that Jesus died "for us", as propagated by the Western classic and objective paradigms of atonement in Christianity, which regard Jesus as dying as a substitute for others, instead of them.
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.
Justification (theology)In Christian theology, justification is the event or process by which sinners are made or declared to be righteous in the sight of God. The means of justification is an area of significant difference amongst the diverse theories of atonement defended within Roman Catholic, Eastern Orthodox, Oriental Orthodox and Protestant theologies. Justification is often seen as being the theological fault line that divided Roman Catholicism from the Lutheran and Reformed traditions of Protestantism during the Reformation.
SatanSatan, also known as the Devil, and sometimes also called Lucifer in Christianity, is an entity in Abrahamic religions that seduces humans into sin or falsehood. In Judaism, Satan is seen as an agent subservient to God, typically regarded as a metaphor for the yetzer hara, or "evil inclination". In Christianity and Islam, he is usually seen as a fallen angel or jinn who has rebelled against God, who nevertheless allows him temporary power over the fallen world and a host of demons.
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.
