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.
IconAn icon () is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, and Catholic churches. They are not simply artworks; "an icon is a sacred image used in religious devotion". The most common subjects include Christ, Mary, saints and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most of the religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints.
God in ChristianityGod in Christianity is believed to be the eternal, supreme being who created and preserves all things. Christians believe in a monotheistic conception of God, which is both transcendent (wholly independent of, and removed from, the material universe) and immanent (involved in the material universe). Christian teachings on the transcendence, immanence, and involvement of God in the world and his love for humanity exclude the belief that God is of the same substance as the created universe (rejection of pantheism) but accept that God the Son assumed hypostatically united human nature, thus becoming man in a unique event known as "the Incarnation".
IdolatryIdolatry is the worship of a or "idol" as though it were God. In Abrahamic religions (namely Judaism, Samaritanism, Christianity, the Baháʼí Faith, and Islam) idolatry connotes the worship of something or someone other than the Abrahamic God as if it were God. In these monotheistic religions, idolatry has been considered as the "worship of false gods" and is forbidden by texts such as the Ten Commandments. Other monotheistic religions may apply similar rules.
NicaeaNicaea, Nicæa or Nicea (naɪ'si:ə , niːˈkae̯.a), also known as Nikaia (Νίκαια, Attic: nǐːkai̯a, Koine: ˈnikεa), was an ancient Greek city in the north-western Anatolian region of Bithynia that is primarily known as the site of the First and Second Councils of Nicaea (the first and seventh Ecumenical councils in the early history of the Christian Church), the Nicene Creed (which comes from the First Council), and as the capital city of the Empire of Nicaea following the Fourth Crusade in 1204, until the recapture of Constantinople by the Byzantines in 1261.
Ecumenical Patriarchate of ConstantinopleThe Ecumenical Patriarchate of Constantinople (Οἰκουμενικὸν Πατριαρχεῖον Κωνσταντινουπόλεως, ikumeniˈkon patriarˈçion konstandinuˈpoleos; Patriarchatus Oecumenicus Constantinopolitanus; Rum Ortodoks Patrikhanesi, İstanbul Ekümenik Patrikhanesi, "Roman Orthodox Patriarchate, Ecumenical Patriarchate") is one of the fifteen to seventeen autocephalous churches (or "jurisdictions") that together compose the Eastern Orthodox Church. It is headed by the Ecumenical Patriarch of Constantinople.
Quinisext CouncilThe Quinisext Council (Concilium Quinisextum; Penthékti Sýnodos), i.e., the Fifth-Sixth Council, often called the Council in Trullo, Trullan Council, or the Penthekte Synod, was a church council held in 692 at Constantinople under Justinian II. It is known as the "Council in Trullo" because, like the Sixth Ecumenical Council, it was held in a domed hall in the Imperial Palace (τρούλος [] meaning a cup or dome). Both the Fifth and the Sixth Ecumenical Councils had omitted to draw up disciplinary canons, and as this council was intended to complete both in this respect, it took the name of Quinisext.
Council of HieriaThe iconoclast Council of Hieria was a Christian council of 754 which viewed itself as ecumenical, but was later rejected by the Second Council of Nicaea (787) and by Catholic and Orthodox churches, since none of the five major patriarchs were represented in Hieria. However it is preferred over Second Nicea by some Protestants. The Council of Hieria was summoned by the Byzantine Emperor Constantine V in 754 in the palace of Hieria at Chalcedon.
Marian devotionsMarian devotions are external pious practices directed to the person of Mary, mother of God, by members of certain Christian traditions. They are performed in Catholicism, High Church Lutheranism, Anglo-Catholicism, Eastern Orthodoxy and Oriental Orthodoxy, but generally rejected in other Christian denominations. Such devotional prayers or may be accompanied by specific requests for Mary's intercession with God. There is significant diversity of form and structure in Marian devotions practiced by different groups of Christians.
IconodulismIconodulism (also iconoduly or iconodulia) designates the religious service to icons (kissing and honourable veneration, incense, and candlelight). The term comes from Neoclassical Greek εἰκονόδουλος (eikonodoulos) (from εἰκόνα – icon (image) + δοῦλος – servant), meaning "one who serves images (icons)". It is also referred to as iconophilism (also iconophily or iconophilia from εἰκόνα – icon (image) + φιλέω – love) designating a positive attitude towards the religious use of icons.
