OrigenOrigen of Alexandria ( 185 – 253), also known as Origen Adamantius, was an early Christian scholar, ascetic, and theologian who was born and spent the first half of his career in Alexandria. He was a prolific writer who wrote roughly 2,000 treatises in multiple branches of theology, including textual criticism, biblical exegesis and hermeneutics, homiletics, and spirituality. He was one of the most influential and controversial figures in early Christian theology, apologetics, and asceticism.
MandaeismMandaeism (Classical Mandaic: mandaiia; Arabic: المندائيّة al-Mandāʾiyya), sometimes also known as Nasoraeanism or Sabianism, is a Gnostic, monotheistic and ethnic religion. Its adherents, the Mandaeans, revere Adam, Abel, Seth, Enos, Noah, Shem, Aram, and especially John the Baptist. Mandaeans consider Adam, Seth, Noah, Shem and John the Baptist prophets, with Adam being the founder of the religion and John being the greatest and final prophet. The Mandaeans speak an Eastern Aramaic language known as Mandaic.
AdoptionismAdoptionism, also called dynamic monarchianism, is an early Christian nontrinitarian theological doctrine, subsequently revived in various forms, which holds that Jesus was adopted as the Son of God at his baptism, his resurrection, or his ascension. How common adoptionist views were among early Christians is debated, but it appears to have been most popular in the first, second, and third centuries. Some scholars see adoptionism as the belief of the earliest followers of Jesus, based on the epistles of Paul and other early literature.
Nag Hammadi libraryThe Nag Hammadi library (also known as the "Chenoboskion Manuscripts" and the "Gnostic Gospels") is a collection of early Christian and Gnostic texts discovered near the Upper Egyptian town of Nag Hammadi in 1945. Thirteen leather-bound papyrus codices buried in a sealed jar were found by a local farmer named Muhammed al-Samman. The writings in these codices comprise 52 mostly Gnostic treatises, but they also include three works belonging to the Corpus Hermeticum and a partial translation/alteration of Plato's Republic.
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.
IrenaeusIrenaeus (ɪrɪˈneɪəs; Εἰρηναῖος Eirēnaios; 130-202 AD) was a Greek bishop noted for his role in guiding and expanding Christian communities in the southern regions of present-day France and, more widely, for the development of Christian theology by combating heterodox or Gnostic interpretations of Scripture as heresy and defining proto-orthodoxy. Originating from Smyrna, he had seen and heard the preaching of Polycarp, who in turn was said to have heard John the Evangelist, and thus was the last-known living connection with the Apostles.
MonotheismMonotheism is the belief that there is only one deity, an all-supreme being that is universally referred to as God. A distinction may be made between exclusive monotheism, in which the one God is a singular existence, and both inclusive and pluriform monotheism, in which multiple gods or godly forms are recognized, but each are postulated as extensions of the same God.
CatharismCatharism was a Christian dualist or Gnostic movement between the 12th and 14th centuries which thrived in Southern Europe, particularly in northern Italy and southern France. Followers were described as Cathars and referred to themselves as Good Christians; in modern times, they are mainly remembered for a prolonged period of mutual conflict and religious persecution - sometimes regarded as genocide - by the Catholic Church which deemed Catharism a heretical sect.
Dualism in cosmologyDualism in cosmology or dualistic cosmology is the moral or spiritual belief that two fundamental concepts exist, which often oppose each other. It is an umbrella term that covers a diversity of views from various religions, including both traditional religions and scriptural religions. Moral dualism is the belief of the great complement of, or conflict between, the benevolent and the malevolent. It simply implies that there are two moral opposites at work, independent of any interpretation of what might be "moral" and independent of how these may be represented.
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.
