First seven ecumenical councilsIn the history of Christianity, the first seven ecumenical councils include the following: the First Council of Nicaea in 325, the First Council of Constantinople in 381, the Council of Ephesus in 431, the Council of Chalcedon in 451, the Second Council of Constantinople in 553, the Third Council of Constantinople from 680–681 and finally, the Second Council of Nicaea in 787. All of the seven councils were convened in modern-day Turkey. These seven events represented an attempt by Church leaders to reach an orthodox consensus, restore peace and develop a unified Christendom.
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.
Calendar of saintsThe calendar of saints is the traditional Christian method of organizing a liturgical year by associating each day with one or more saints and referring to the day as the feast day or feast of said saint. The word "feast" in this context does not mean "a large meal, typically a celebratory one", but instead "an annual religious celebration, a day dedicated to a particular saint". The system arose from the early Christian custom of commemorating each martyr annually on the date of their death, or birth into heaven, a date therefore referred to in Latin as the martyr's dies natalis ('day of birth').
Biblical studiesBiblical studies is the academic application of a set of diverse disciplines to the study of the Bible (the Old Testament and New Testament). For its theory and methods, the field draws on disciplines ranging from ancient history, historical criticism, philology, theology, textual criticism, literary criticism, historical backgrounds, mythology, and comparative religion. Many secular as well as religious universities and colleges offer courses in biblical studies, usually in departments of religious studies, theology, Judaic studies, history, or comparative literature.
Synoptic GospelsThe gospels of Matthew, Mark, and Luke are referred to as the synoptic Gospels because they include many of the same stories, often in a similar sequence and in similar or sometimes identical wording. They stand in contrast to John, whose content is largely distinct. The term synoptic (synopticus; συνοπτικός) comes via Latin from the Greek σύνοψις, synopsis, i.e. "(a) seeing all together, synopsis"; the sense of the word in English, the one specifically applied to these three gospels, of "giving an account of the events from the same point of view or under the same general aspect" is a modern one.
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.
Clement of AlexandriaTitus Flavius Clemens, also known as Clement of Alexandria (Κλήμης ὁ Ἀλεξανδρεύς; 150 – 215 AD), was a Christian theologian and philosopher who taught at the Catechetical School of Alexandria. Among his pupils were Origen and Alexander of Jerusalem. A convert to Christianity, he was an educated man who was familiar with classical Greek philosophy and literature. As his three major works demonstrate, Clement was influenced by Hellenistic philosophy to a greater extent than any other Christian thinker of his time, and in particular, by Plato and the Stoics.
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.
ExegesisExegesis (ˌɛksɪˈdʒiːsɪs ; from the Greek ἐξήγησις, from ἐξηγεῖσθαι, "to lead out") is a critical explanation or interpretation of a text. The term is traditionally applied to the interpretation of Biblical works. In modern usage, exegesis can involve critical interpretations of virtually any text, including not just religious texts but also philosophy, literature, or virtually any other genre of writing. The phrase Biblical exegesis can be used to distinguish studies of the Bible from other critical textual explanations.
HomoiousianHomoiousios (ὁμοιούσιος from ὅμοιος, hómoios, "similar" and οὐσία, ousía, "essence, being") is a Christian theological term, coined in the 4th century to identify a distinct group of Christian theologians who held the belief that God the Son was of a similar, but not identical, essence (or substance) with God the Father. It is often claimed that Homoiousianism arose as an attempt to reconcile two opposing teachings, namely, Homoousianism and Homoianism: Homoousios is a keyword in the Nicene Creed of the year 325 and means "same substance.
