Epiphanius of SalamisEpiphanius of Salamis (Ἐπιφάνιος; c. 310–320 – 403) was the bishop of Salamis, Cyprus, at the end of the 4th century. He is considered a saint and a Church Father by both the Eastern Orthodox and Catholic Churches. He gained a reputation as a strong defender of orthodoxy. He is best known for composing the Panarion, a compendium of eighty heresies, which included also pagan religions and philosophical systems.
HeresyHeresy is any belief or theory that is strongly at variance with established beliefs or customs, particularly the accepted beliefs or religious law of a religious organization. A heretic is a proponent of heresy. Heresy in Christianity, Judaism, and Islam has at times been met with censure ranging from excommunication to the death penalty. Heresy is distinct from apostasy, which is the explicit renunciation of one's religion, principles or cause; and from blasphemy, which is an impious utterance or action concerning God or sacred things.
ArianismArianism (Ἀρειανισμός, Areianismós) is a Christological doctrine first attributed to Arius (AD 256–336), a Christian presbyter from Alexandria, Egypt. Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before "time" by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time as time applies only to the creations of God.
Athanasius of AlexandriaAthanasius I of Alexandria (296–298 – 2 May 373), also called Athanasius the Great, Athanasius the Confessor, or, among Coptic Christians, Athanasius the Apostolic, was a church father and the 20th pope of Alexandria (as Athanasius I). His intermittent episcopacy spanned 45 years (8 June 328 – 2 May 373), of which over 17 encompassed five exiles, when he was replaced on the order of four different Roman emperors. Athanasius was a Christian theologian, a Church Father, the chief defender of Trinitarianism against Arianism, and a noted Egyptian Christian leader of the fourth century.
SocinianismSocinianism (səˈsɪniənɪzəm) is a Nontrinitarian Christian belief system developed and co-founded during the Protestant Reformation by the Italian Renaissance humanists and theologians Lelio Sozzini (Latin: Laelius Socinus) and Fausto Sozzini (Latin: Faustus Socinus), uncle and nephew, respectively. It was developed among the Polish Brethren in the Polish Reformed Church between the 16th and 17th centuries, and embraced by the Unitarian Church of Transylvania during the same period.
DonatismDonatism was a Christian sect leading to a schism in the Church, in the region of the Church of Carthage, from the fourth to the sixth centuries. Donatists argued that Christian clergy must be faultless for their ministry to be effective and their prayers and sacraments to be valid. Donatism had its roots in the long-established Christian community of the Roman province Africa Proconsularis (present-day Tunisia, the northeast of Algeria, and the western coast of Libya) and Mauretania Tingitana (roughly with the northern part of present-day Morocco), in the persecutions of Christians under Diocletian.
AmbroseAmbrose of Milan (Aurelius Ambrosius; 339 - 4 April 397), venerated as Saint Ambrose, was a theologian and statesman who served as Bishop of Milan from 374 to 397. He expressed himself prominently as a public figure, fiercely promoting Roman Christianity against Arianism and paganism. He left a substantial collection of writings, of which the best known include the ethical commentary De officiis ministrorum (377–391), and the exegetical Exameron (386–390).
Book burningBook burning is the deliberate destruction by fire of books or other written materials, usually carried out in a public context. The burning of books represents an element of censorship and usually proceeds from a cultural, religious, or political opposition to the materials in question. Book burning can be an act of contempt for the book's contents or author, intended to draw wider public attention to this opinion, or conceal the information contained in the text from being made public, such as diaries or ledgers.
Arian controversyThe Arian controversy was a series of Christian disputes about the nature of Christ that began with a dispute between Arius and Athanasius of Alexandria, two Christian theologians from Alexandria, Egypt. The most important of these controversies concerned the relationship between the substance of God the Father and the substance of His Son. Emperor Constantine, through the Council of Nicaea in 325, attempted to unite Christianity and establish a single, imperially approved version of the faith.
OusiaOusia (ˈuːziə,_ˈuːsiə,_ˈuːʒə,_ˈuːʃə; οὐσία) is a philosophical and theological term, originally used in ancient Greek philosophy, then later in Christian theology. It was used by various ancient Greek philosophers, like Plato and Aristotle, as a primary designation for philosophical concepts of essence or substance. In contemporary philosophy, it is analogous to English concepts of being and ontic. In Christian theology, the concept of θεία ουσία (divine essence) is one of the most important doctrinal concepts, central to the development of trinitarian doctrine.
