Constantine the Great and ChristianityDuring the reign of the Roman Emperor Constantine the Great (306–337 AD), Christianity began to transition to the dominant religion of the Roman Empire. Historians remain uncertain about Constantine's reasons for favoring Christianity, and theologians and historians have often argued about which form of early Christianity he subscribed to. There is no consensus among scholars as to whether he adopted his mother Helena's Christianity in his youth, or, as claimed by Eusebius of Caesarea, encouraged her to convert to the faith he had adopted.
Eusebius of NicomediaEusebius of Nicomedia (juːˈsiːbiəs; Εὐσέβιος; died 341) was an Arian priest who baptized Constantine the Great on his deathbed in 337. A fifth-century legend evolved that Pope Sylvester I was the one to baptize Constantine, but this is dismissed by scholars as a forgery 'to amend the historical memory of the Arian baptism that the emperor received at the end of his life, and instead to attribute an unequivocally orthodox baptism to him.' He was a bishop of Berytus (modern-day Beirut) in Phoenicia.
Edict of MilanThe Edict of Milan (Edictum Mediolanense; Διάταγμα τῶν Μεδιολάνων, Diatagma tōn Mediolanōn) was the February 313 AD agreement to treat Christians benevolently within the Roman Empire. Western Roman Emperor Constantine I and Emperor Licinius, who controlled the Balkans, met in Mediolanum (modern-day Milan) and, among other things, agreed to change policies towards Christians following the edict of toleration issued by Emperor Galerius two years earlier in Serdica.
PeshittaThe Peshitta (ܦܫܺܝܛܬܳܐ or ܦܫܝܼܛܬܵܐ ) is the standard version of the Bible for churches in the Syriac tradition, including the Maronite Church, the Chaldean Catholic Church, the Syriac Catholic Church, the Syriac Orthodox Church, the Malabar Independent Syrian Church (Thozhiyoor Church), the Syro-Malankara Catholic Church, the Assyrian Church of the East and the Syro-Malabar Church.
Chi RhoThe Chi Rho (☧, English pronunciation ˈkaɪ_ˈroʊ; also known as chrismon) is one of the earliest forms of Christogram, formed by superimposing the first two (capital) letters—chi and rho (ΧΡ)—of the Greek word ΧΡΙΣΤΟΣ (Christos) in such a way that the vertical stroke of the rho intersects the center of the chi. The Chi-Rho symbol was used by the Roman Emperor Constantine I (r. 306–337 AD) as part of a military standard (vexillum). Constantine's standard was known as the Labarum.
Paul of SamosataPaul of Samosata (Παῦλος ὁ Σαμοσατεύς, lived from 200 to 275 AD) was Bishop of Antioch from 260 to 268 and the originator of the Paulianist heresy named after him. He was a believer in monarchianism, a nontrinitarian doctrine; his teachings reflect adoptionism. Paul was born at Samosata into a family of humble origin. He was elected bishop of Antioch in 260. He held the civil office of Procurator ducenarius. His Monarchianist teachings aroused strong opposition in the church. He was also accused of corruption on a grand scale.
Easter letterThe Festal Letters or Easter Letters are a series of annual letters by which the Bishops of Alexandria, in conformity with a decision of the First Council of Nicaea, announced the date on which Easter was to be celebrated. The council chose Alexandria because of its famous school of astronomy, and the date of Easter depends on the spring equinox and the phases of the moon. The most famous of those letters are those authored by Athanasius, a collection of which was rediscovered in a Syriac translation in 1842.
Catechetical School of AntiochThe Catechetical School of Antioch was one of the two major centers of the study of biblical exegesis and theology during Late Antiquity; the other was the Catechetical School of Alexandria. This group was known by this name because the advocates of this tradition were based in the city of Antioch, one of the major cities of the ancient Roman Empire.
Chronicon PaschaleChronicon Paschale (the Paschal or Easter Chronicle), also called Chronicum Alexandrinum, Constantinopolitanum or Fasti Siculi, is the conventional name of a 7th-century Greek Christian chronicle of the world. Its name comes from its system of chronology based on the Christian paschal cycle; its Greek author named it Epitome of the ages from Adam the first man to the 20th year of the reign of the most August Heraclius. The 'Chronicon Paschale' follows earlier chronicles.
Syriac literatureSyriac literature is literature in the Syriac language. It is a tradition going back to the Late Antiquity. It is strongly associated with Syriac Christianity. In modern Syriac studies, and also within the wider field of Aramaic studies, the term Syriac literature is most commonly used as a shortened designation for Classical Syriac literature, that is written in Classical Syriac language, an old literary and liturgical language of Syriac Christianity.
