Is there anybody, who don't have heard anything about angels till now? If someone was not brought up in contact to religion, he knows them, the angels. But what does it mean exactly?The word 'angel' means messenger, because they take gods will to the human beings, and this in many religions. Angels aren't described in the New and Old Testament, their appearance and nature are not specified, unless they appear the human beings in the shape of human beings.You may read something about their appearance in the Book of Revelation.
In the New Testament unlike the Old Testament angels are described deprecative. Paulus tells that human beings stay above the angels. Although it came to worships of angels (angelolatry) and the theory of angels (angelology) was advanced.
Today some human beings don't beliefe in angels anymore. After biblical texts were researched most exactly, angels became myths of the Bible and lost their function for a lot of human beings, apart for those who saw angels themselves.If humans are near to death, they often see angels. They send them messages of God, which affect their life rigorous: they see the world in another wise and another reality, whereby they can master their crisises. But this meetings are incapable of proof all times.
Angels are disposed in a hierarchy. At the bottom you find the messengers which takes Gods messages to human beings, and the guardian angels.At the top there are angels which are convened at Gods throne and praise him. In the Bible they are described as creatures with bodies of lions or wings of eagles, and sometimes with lots of eyes. This images show the glory in heaven and a multiplicity of species.
Angels are Gods Creation and his servants, therefore they shouldn't be adored but respected and esteemed.
Definition out of a lexicon
Angel (Latin angelus; Greek aggelos; from the Hebrew for 'one going' or 'one sent'; messenger). The word is used in Hebrew to denote indifferently either a divine or human messenger. The Septuagint renders it by aggelos which also has both significations. The Latin version, however, distinguishes the divine or spirit-messenger from the human, rendering the original in the one case by angelus and in the other by legatus or more generally by nuntius. In a few passages the Latin version is misleading, the word angelus being used where nuntius would have better expressed the meaning, e.g. Isaiah 18:2; 33:3, 6.
The angels are represented throughout the Bible as a body of spiritual beings intermediate between God and men: 'You have made him (man) a little less than the angels' (Psalm 8:6). They, equally with man, are created beings; 'praise ye Him, all His angels: praise ye Him, all His hosts . . . for He spoke and they were made. He commanded and they were created' (Psalm 148:2, 5: Colossians 1:16, 17). That the angels were created was laid down in the Fourth Lateran Council (1215). The decree 'Firmiter' against the Albigenses declared both the fact that they were created and that men were created after them. This decree was repeated by the Vatican Council, 'Dei Filius'. We mention it here because the words: 'He that liveth for ever created all things together' (Ecclesiasticus 18:1) have been held to prove a simultaneous creation of all things; but it is generally conceded that 'together' (simul) may here mean 'equally', in the sense that all things were 'alike' created. They are spirits; the writer of the Epistle to the Hebrews says: 'Are they not all ministering spirits, sent to minister to them who shall receive the inheritance of salvation?' (Heb. i, 14).
About angels in the Bible
Angels appear in the Bible from the beginning to the end, from the Book of Genesis to the Book of Revelation. The Bible is our best source of knowledge about angels - for example, Psalms 91:11, Matthew 18:10 and Acts 12:15 indicate humans have guardian angels. Angels announce the birth of Jesus to the shepherds [Luke 2:14], minister to Christ after his temptation in the desert [Matthew 4:11], comforted Jesus in his agony in the garden [Luke 22:43], and appear to announce his resurrection from the dead [John 20:12] . According to Jesus, the angels of little ones continually behold the face of the Father [Matthew 18:10]; angels will come with Him on the Day of Judgement [Matthew 24:31], and the angels will separate the wicked from the just on the last day [Matthew 13:49], although they do not know the day of Judgement[Mark 13:32]; and the children of the resurrection will be equal to the angels [Luke 20:34]. Thomas Aquinas was a great medieval theologian, and is known as the 'Angelic Doctor' for his extensive writings on angels in his book, the Summa Theologica. The word 'angelos' in Greek means messenger. Angels are purely spiritual beings that do God's will [Psalms 103:20, Matthew 26:53]. He points out that sometimes angels take human form, as seen in the three men who appear to Abraham in the Book of Genesis, the two angels who appeared to Lot before the destruction of Sodom and Gomorrah, or Raphael appearing in human form to Tobias. Thomas Aquinas believed that angels, being spiritual beings, influence mankind by illuminating one's mind with an idea. Michael is one of the leading angels, and is considered 'Prince' of the heavenly hosts, and the Guardian Angel of Persia [Daniel 10:13]. He is the only one in the Bible referred to as an Archangel [Jude 1:9], and serves a major role in Chapter 12 of the Book of Revelation. The angel Gabriel first appears in a vision to Daniel [Daniel 8:16], but is best known for the Annunciation to Mary that she would be the Mother of Jesus [Luke 1:26-38]. The Book of Tobit names Raphael as 'one of the seven who stand before the Lord.'Thomas Aquinas, quoting Scripture, the Apostle Paul and Dionysius, an Athenian converted by Paul [Acts 17:34], names 9 orders of angels in 3 groups: the highest hierarchy being next to God, Seraphim [Isaiah 6:2], Cherubim [Genesis 3:24, Ezekiel 10:1-22], and Thrones [Colossians 1:16]; the middle hierarchy involved in government, Dominions [Colossians 1:16], Virtues [1 Peter 3:22], and Powers [Col 1:16]; and the third hierarchy involved in work, Principalities [Col 1:16], Archangels [1 Thessalonians 4:16], and Angels.
