An angel is a pure spirit created by God. The Old Testament theology included the belief in angels: the name applied to certain spiritual beings or intelligences of heavenly residence, employed by God as the ministers of His will.
Are Angels ambassadors sent from God to guide us, protect us or bring messages from heaven? The word angel comes from the Greek word "angelos" which means messenger. The Bible says that God has appointed many angels to those who love God and call to Him, "Psalms 91:11 For He shall give His angels charge over you, To keep you in all your ways." The bible refers to different types of angels, with varying duties such as ugides, protectors, messengers and angels of the Lord, or as Cherubim, Seraphim, or Archangels, and not to be worshipped for they are "creatures" Col. 2:18; Rev. 19:10; 22:9.
The meanings of angels, their appearance and purposes vary throughout history and the world. Artists have given us their visions of angels as winged creatures, usually beautiful figures that are glowing, shining, floating, in human form or as a voice. Saints as well as everyday people tell about being visited by or helped by angels
In the bible, angels have appeared as messengers, guides, and healers. They also make up the celestial court. "And I beheld and I heard the voice of many angels round about the throne, and the number of them was thousands of thousands." - St. John, the Evangelist. Angels are even recorded in the Koran, "You shall see the angels circling around the throne, giving glory to their Lord".
The world's great literature and art tell us about many angel characters - some we're familiar with and some obscure to us now. Yet, the common thread that weaves amongst the legends and the lore is the undeniable influence that angels have had upon nearly every culture and religion known to man
Types of Angels
There are different types of angels depicted in the bible that have varying degrees of divine missions, different names and descriptions. First of all they are said to be with God
Angels are found throughout the Old Testament and also in the New Testament, though less often. Origen, one of the earliest biblical scholars living at the time of the first Century, recognized the notion of Guardian Angels. St. Jerome told us that each of us is given a Guardian Angel at birth, and St. Thomas concurred with this belief. The Old Testament was not explicit on a personal Guardian Angel but there was a belief that guardian angels put people under their protection
Angels of the Lord" "As he considered this, he fell asleep, and an angel of the Lord appeared to him in a dream. "Joseph, son of David," the angel said, "do not be afraid to go ahead with your marriage to Mary. For the child within her has been conceived by the Holy Spirit. When Joseph woke up, he did what the angel of the Lord commanded. He brought Mary home to be his wife." Matthew 1:20-24
Dionysius, a 5th or 6th century writer gives us the hierarchical order of the angels. The first group is the seraphim, cherubim and thrones. The word seraphim (singular is saraph) is taken from the fiery imagery often associated with the Presence of God-- Ezek. 1:27. Cherubim are represented as guardians with many wings. Thrones have been depicted wearing stoles and kneeling before God
Seraphim stood above Him, each having six wings; with two he covered his face, and with two he covered his feet, and with two he flew" . Isaiah 6:2
So He drove out the man; and placed at the east of the garden of Eden Cherubim, and a flaming sword which turned every way, to keep the way of the tree of life". Gen. 3:24
The 2nd group is composed of dominations, virtues and powers. Each group is associated with specific symbols. The dominations held scepters and wore crowns. The virtues are shown with flasks of perfume, trumpets, and rays of lightening. The powers are depicted wielding flaming swords
