Angels? What exactly are they

   First off let me start by saying Archangel Rafael will not be discussed since I have never read the appocryphal/deutercononical books and theirfore dont have a theological opinion on this matter and I am not going to comment on what I know but on what God has already revealed to me. To start off Arch Angels are high ranked angel who is in charge of other angels.

  Gabriel is well knowan an angel who typically serves as a messenger sent from God to certain people. From Wikipedia "The Gospel of Luke, Gabriel appeared to Zecharias, and to the virgin Mary foretelling the births of John the Baptist and Jesus, respectively (Luke 1:11–38). In the Book of Daniel, he is referred to as "the man Gabriel", while in the Book of Luke, Gabriel is referred to as "an angel of the Lord" (Luke 1:11). Now Michael is known more as a warrior- from Wikipedia "Michael is mentioned three times in the Book of Daniel, once as a "great prince who stands up for the children of your people". In the book of Revalation we are told that Michael shall be the leader of God's army against that of Satan. where during the war in heaven he defeats Satan. The Epistle of Jude Michael is specifically referred to as an "archangel".

  Regular angels are often charecterised as messengers of God (which they are). It is a source of debate whether they have wings and whether their phyiscal or strictly spiritual beings, however this is of no great theological importance. Angels are creatures of good, spirits of love, and messengers of the savior Jesus Christ (well except for the fallen ones). Diffrent angels are considered to have diffrent roles that they are used for. And although angels have greater knowledge than men, they are not omniscient, as Matthew 24:36 points out. Also we are told that after we are redeemed and saved in heaven we will be above angels (which some have suggested is one of the Reasons lucifer rebelled against God.

  While their is no direct connection to quote end quote Guardian Angels in the bible, we do see that at least some angels take on a similar wrole to what is often considered a guardian angel. While the term guardian angel doesnt exist within the bible, for all intesive purposes some angels basically have the same role as Pslam 91 tells us make it clear that angels do watch over us and that angels are extremely interested in us believers. Mathew 18:10 Jesus: "Beware that you don't look down on any of these little ones. For I tell you that in heaven their angels are always in the presence of my heavenly Father."....  so basically for all intesive purpose children have guardian angels just not in terms of that particular word.

Hope this helps, God Bless.
