DoxologyA doxology (Ancient Greek: δοξολογία doxologia, from δόξα, doxa 'glory' and -λογία, -logia 'saying') is a short hymn of praises to God in various forms of Christian worship, often added to the end of canticles, psalms, and hymns. The tradition derives from a similar practice in the Jewish synagogue, where some version of the Kaddish serves to terminate each section of the service. Among Christian traditions a doxology is typically an expression of praise sung to the Holy Trinity: the Father, the Son, and the Holy Spirit.
New CovenantThe New Covenant (Hebrew beˈʁit χaˈdaʃah; Koine Greek διαθήκη καινή diathḗkē kainḗ ðiaˈθici ceˈni) is a biblical interpretation which was originally derived from a phrase which is contained in the Book of Jeremiah (Jeremiah 31:31–34), in the Hebrew Bible (or the Old Testament of the Christian Bible). Generally, Christians believe that the promised New Covenant was instituted at the Last Supper as part of the Eucharist, which, in the Gospel of John, includes the New Commandment.
Original sin'Original sin' is the Christian doctrine that holds that humans, through the fact of birth, inherit a tainted nature with a proclivity to sinful conduct in need of regeneration. The biblical basis for the belief is generally found in Genesis 3 (the story of the expulsion of Adam and Eve from the Garden of Eden), in a line in Psalm 51:5 ("I was brought forth in iniquity, and in sin did my mother conceive me"), and in Paul's Epistle to the Romans, 5:12-21 ("Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned").
Eastern ChristianityEastern Christianity comprises Christian traditions and church families that originally developed during classical and late antiquity in Western Asia, Asia Minor, Eastern Europe, Southeastern Europe, the Caucasus, Northeast Africa, the Fertile Crescent and the Malabar coast of South Asia, and ephemerally parts of Persia, Central Asia and the Far East. The term does not describe a single communion or religious denomination.
Hypostatic unionHypostatic union (from the Greek: ὑπόστασις hypóstasis, "person, subsistence") is a technical term in Christian theology employed in mainstream Christology to describe the union of Christ's humanity and divinity in one hypostasis, or individual personhood. The most basic explanation for the hypostatic union is Jesus Christ being both fully God and fully man. He is both perfectly divine and perfectly human and has two complete and distinct natures at once.
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.
Biblical inspirationBiblical inspiration is the doctrine in Christian theology that the human writers and canonizers of the Bible were led by God with the result that their writings may be designated in some sense the word of God. This belief is traditionally associated with concepts of the biblical infallibility and the internal consistency of the Bible. At 2 Tim 3:16 (NRSV), it is written: "All scripture is inspired by God [theopneustos] and is useful for teaching".
UnitarianismUnitarianism () is a Nontrinitarian branch of Christianity. Unitarian Christians affirm the unitary nature of God as the singular and unique creator of the universe, believe that Jesus Christ was inspired by God in his moral teachings and that he is the savior of humankind, but he is not comparable or equal to God himself. Unitarianism was established in order to restore "primitive Christianity before [what Unitarians saw as] later corruptions setting in"; Likewise, Unitarian Christians generally reject the doctrine of original sin.
Son of GodHistorically, many rulers have assumed titles such as the son of God, the son of a god or the son of heaven. The term "son of God" is used in the Hebrew Bible as another way to refer to humans who have a special relationship with God. In Exodus, the nation of Israel is called God's firstborn son. Solomon is also called "son of God". Angels, just and pious men, and the kings of Israel are all called "sons of God." In the New Testament of the Christian Bible, "Son of God" is applied to Jesus on many occasions.
Four Horsemen of the ApocalypseThe Four Horsemen of the Apocalypse are figures in the Book of Revelation in the New Testament of the Bible, a piece of apocalypse literature written by John of Patmos. They are not specifically identified there but subsequent commentary often identifies them as personifications of Death, Famine, War, and Conquest. Revelation 6 tells of a book or scroll in God's right hand that is sealed with seven seals. The Lamb of God/Lion of Judah opens the first four of the seven seals, which summons four beings that ride out on white, red, black, and green horses.
