Early ChristianityEarly Christianity, or Paleochristianity, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians. Early Christianity contains the Apostolic age and is followed by, and substantially overlaps with, the Patristic era.
Church of the EastThe Church of the East ( ʿĒḏtā d-Maḏenḥā) or the East Syriac Church, also called the Church of Seleucia-Ctesiphon, the Persian Church, the Assyrian Church, the Babylonian Church or the Nestorian Church, was an Eastern Christian church of the East Syriac Rite, based in Mesopotamia. It was one of three major branches of Eastern Christianity that arose from the Christological controversies of the 5th and 6th centuries, alongside the Oriental Orthodox Churches and the Chalcedonian Church.
EdessaEdessa (ɪˈdɛsə, ; Édessa) was an ancient city (polis) in Upper Mesopotamia, founded during the Hellenistic period by King Seleucus I Nicator (305-281), founder of the Seleucid Empire. It later became capital of the Kingdom of Osroene, and continued as capital of the Roman province of Osroene. In Late Antiquity, it became a prominent center of Christian learning and seat of the Catechetical School of Edessa. During the Crusades, it was the capital of the County of Edessa.
NusaybinNusaybin (nuˈsajbin), historically known as Nisibis (Nísibis) or Nesbin, is a city and the seat of the Nusaybin District of the Mardin Province in Turkey. The city is populated by Kurds of different tribal affiliation and had a population of 84,445 in 2021. Nusaybin is separated from the larger Kurdish-majority city of Qamishli by the Syria–Turkey border. The city is at the foot of the Mount Izla escarpment at the southern edge of the Tur Abdin hills, standing on the banks of the Jaghjagh River (Çağçağ), the ancient Mygdonius (Μυγδόνιος).
Syriac Orthodox ChurchThe Syriac Orthodox Church (ʿIdto Sūryoyto Trīṣath Shubḥo; الكنيسة السريانية الأرثوذكسية, സുറിയാനി ഓർത്തഡോക്സ് സഭ), also known as West Syriac Church or West Syrian Church, officially known as the Syriac Orthodox Patriarchate of Antioch and All the East, and informally as the Jacobite Church, is an Oriental Orthodox church that branched from the Church of Antioch. The bishop of Antioch, known as the patriarch, heads the church and possesses apostolic succession through Saint Peter (Šemʿōn Kēp̄ā), according to sacred tradition.
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.
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.
PatristicsPatristics or patrology is the study of the early Christian writers who are designated Church Fathers. The names derive from the combined forms of Latin pater and Greek patḗr (father). The period of the Church Fathers, commonly called the Patristic era, is generally considered to run from the end of New Testament times or end of the Apostolic Age (AD 100) to either AD 451 (the date of the Council of Chalcedon) or to the Second Council of Nicaea in 787.
Syriac languageThe Syriac language (ˈsɪriæk; / Leššānā Sūryāyā, Leshono Suryoyo), also known as Syriac Aramaic (Syrian Aramaic, Syro-Aramaic) and Classical Syriac ܠܫܢܐ ܥܬܝܩܐ (in its literary and liturgical form), is an Aramaic dialect that emerged during the first century AD from a local Aramaic dialect that was spoken in the ancient region of Osroene, centered in the city of Edessa. During the Early Christian period, it became the main literary language of various Aramaic-speaking Christian communities in the historical region of Ancient Syria and throughout the Near East.
Saint PeterSaint Peter (died between AD 64 and 68), also known as Peter the Apostle, Simon Peter, Simeon, Simon, or Cephas ( () 'rock'), was one of the Twelve Apostles of Jesus Christ and one of the first leaders of the early Christian Church. He appears repeatedly and prominently in all four New Testament gospels as well as the Acts of the Apostles. According to Christian tradition, Peter was crucified in Rome under Emperor Nero.
