Christianity in the 1st centuryChristianity in the 1st century covers the formative history of Christianity from the start of the ministry of Jesus (27–29 AD) to the death of the last of the Twelve Apostles (100) and is thus also known as the Apostolic Age. Early Christianity developed out of the eschatological ministry of Jesus. Subsequent to Jesus' death, his earliest followers formed an apocalyptic messianic Jewish sect during the late Second Temple period of the 1st century.
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.
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.
EbionitesEbionites (Ebiōnaîoi, derived from Hebrew אֶבְיוֹנִים (or אֶבְיוֹנִם), ʾEḇyōnīm, meaning 'the poor' or 'poor ones') as a term refers to a Jewish Christian sect, which viewed poverty as a blessing, that existed during the early centuries of the Common Era. The Ebionites embraced an adoptionist Christology, thus understanding Jesus of Nazareth as a mere man who, by virtue of his righteousness in following the Law of Moses, was chosen by God to be the messianic "prophet like Moses".
Mani (prophet)Mani (in Middle Persian: 𐭌𐭀𐭍𐭉/𐭬𐭠𐭭𐭩/𐮋𐮀𐮌𐮈/𐬨𐬁𐬥𐬌/𐫖𐫀𐫗𐫏 Māni, New Persian: Māni, Chinese: Móní, Syriac Mānī, Greek Μάνης, Latin Manes; also Μανιχαῖος, Latin Manichaeus, from Syriac ܡܐܢܝ ܚܝܐ Mānī ḥayyā "Living Mani", April AD 216–2 March AD 274 or 26 February AD 277) was an Iranian prophet and the founder of Manichaeism, a religion most prevalent in late antiquity. Mani was born in or near Seleucia-Ctesiphon (south of modern Baghdad) in Mesopotamia, at the time part of the Parthian Empire.
Nazarene (sect)The Nazarenes (or Nazoreans; Greek: Ναζωραῖοι, Nazōraioi) were an early Jewish Christian sect in first-century Judaism. The first use of the term is found in the Acts of the Apostles () of the New Testament, where Paul the Apostle is accused of being a ringleader of the sect of the Nazarenes ("πρωτοστάτην τε τῆς τῶν Ναζωραίων αἱρέσεως") before the Roman procurator Antonius Felix at Caesarea Maritima by Tertullus. At that time, the term simply designated followers of Jesus of Nazareth, as the Hebrew term (nôṣrî), and the Arabic term نَصْرَانِي (naṣrānī), still do.
MandaeansMandaeans (المندائيون al-Mandāʾiyyūn), also known as Mandaean Sabians (الصابئة المندائيون al-Ṣābiʾa al-Mandāʾiyyūn) or simply as Sabians (الصابئة al-Ṣābiʾa), are an ethnoreligious group who are followers of Mandaeism. They believe that John the Baptist was the final and most important prophet. They may have been among the earliest religious groups to practice baptism, as well as among the earliest adherents of Gnosticism, a belief system of which they are the last surviving representatives today.
GnosticismGnosticism (from Ancient Greek: γνωστικός, romanized: gnōstikós, Koine Greek: [ɣnostiˈkos], 'having knowledge') is a collection of religious ideas and systems that coalesced in the late 1st century AD among Jewish and early Christian sects. These various groups emphasized personal spiritual knowledge (gnosis) above the proto-orthodox teachings, traditions, and authority of religious institutions. Gnostic cosmogony generally presents a distinction between a supreme, hidden God and a malevolent lesser divinity (sometimes associated with the God of the Hebrew Bible) who is responsible for creating the material universe.
