Christian theology

===Angelology===
{{Main|Heavenly host|Christian angelic hierarchy}}
Most descriptions of angels in the Bible describe them in military terms. For example, in terms such as encampment ([http://www.bible.org/netbible/gen32.htm Gen.32:1–2]), command structure ([http://bible.org/netbible/psa91.htm Ps.91:11–12]; [http://bible.org/netbible/mat13.htm Matt.13:41]; [http://bible.org/netbible/index.htm?rev7.htm Rev.7:2]), and combat ([http://bible.org/netbible/index.htm?jdg5.htm Jdg.5:20]; [http://bible.org/netbible/index.htm?job19.htm Job 19:12]; [http://bible.org/netbible/index.htm?rev12.htm Rev.12:7]).

Its specific hierarchy differs slightly from the [[Christian angelic hierarchy|Hierarchy of Angels]] as it surrounds more military services, whereas the Hierarchy of angels is a division of angels into non-military services to God.

====Members of the heavenly host====
{{Main|Cherub}}
Cherubim are depicted as accompanying God's chariot-throne ([http://bible.org/netbible/psa80.htm Ps.80:1]). {{bibleverse||Exodus|25:18–22}} refers to two Cherub statues placed on top of the [[Ark of the Covenant]], the two cherubim are usually interpreted as guarding the throne of God. Other guard-like duties include being posted in locations such as the gates of Eden ([http://bible.org/netbible/gen3.htm Gen.3:24]). Cherubim were mythological winged bulls or other beasts that were part of ancient Near Eastern traditions.<ref>{{cite encyclopedia |url=https://books.google.com/books?id=P9sYIRXZZ2MC |encyclopedia=Eerdmans Dictionary of the Bible |first1=David Noel |last1=Freedman |first2=Allen C. |last2=Myers |first3=Astrid B. |last3=Beck |publisher=Wm.

{{Main|Archangel}}
This angelic designation might be given to angels of various ranks. An example would be [[Raphael (archangel)|Raphael]] who is ranked variously as a Seraph, Cherub, and Archangel .<ref>{{Cite book|last = Davidson |first = Gustav | orig-year = 1967 | year = 1994 | title = A Dictionary of Fallen Angels, Including the Fallen Angels | publisher = Macmillan, Inc. | location = New York, NY | isbn = 978-0-02-907052-9 }}</ref> This is usually a result of conflicting schemes of hierarchies of angels.

{{Main|Angel}}
It is not known how many angels there are but one figure given in [http://bible.org/netbible/rev5.htm Revelation 5:11] for the number of "many angels in a circle around the throne, as well as the living creatures and the elders" was "ten thousand times ten thousand", which would be 100 million.

====Demonology: Fallen angels====

{{Main|Christian demonology|Demon|Fallen angel}}
In most of [[Christianity]], a fallen angel is an [[angel]] who has been [[exile]]d or banished from [[Heaven]]. Often such banishment is a punishment for disobeying or rebelling against [[God]] (see [[War in Heaven]]). The best-known fallen angel is [[Lucifer]]. Lucifer is a name frequently given to [[Satan]] in [[Christianity|Christian]] belief. This usage stems from a particular interpretation, as a reference to a fallen angel, of a passage in the [[Bible]] ({{Bibleverse||Isaiah|14:3–20|ESV}}) that speaks of someone who is given the name of "Day Star" or "Morning Star" (in [[Latin]], ''Lucifer'') as fallen from heaven. The [[Greek Language|Greek]] etymological synonym of Lucifer, Φωσφόρος (''Phosphoros'', "light-bearer").<ref>{{Cite web|url=http://scripturetext.com/2_peter/1-19.htm |title=ScriptureText.com |publisher=ScriptureText.com |access-date=2010-08-08}}</ref><ref>{{Cite web|url=http://www.etymonline.com/index.php?term=phosphorous |title=Etymonline.com |publisher=Etymonline.com |access-date=2010-08-08}}</ref> is used of the morning star in {{Bibleverse|2|Peter|1:19|ESV}} and elsewhere with no reference to Satan. But Satan is called Lucifer in many writings later than the Bible, notably in Milton's ''[[Paradise Lost]]'' (7.131–134, among others), because, according to Milton, Satan was "brighter once amidst the host of Angels, than that star the stars among."

Allegedly, fallen angels are those which have committed one of the seven deadly sins. Therefore, are banished from heaven and suffer in hell for all eternity. Demons from hell would punish the fallen angel by ripping out their wings as a sign of insignificance and low rank.
