Both the Greek and Hebrew words expressing the concept "angel" means "messenger". Angels often fulfill this role in the texts of the Bible, but the authors it is often give this term a different meaning. Good and evil angels, messengers of God and the devil, converge in the decisive battle described in the Book of Revelation. Angels can be ordinary people, prophets, inspirers of good deeds, supernatural bearers of all kinds of news or mentors, and even impersonal forces, like the winds, cloud pillars, or fire that led the Israelites during their Exodus from Egypt. Plague and pestilence are called evil angels. St. Paul calls his illness "Satan's messenger." Many other phenomena, such as inspiration, sudden promptings, Providence, are also attributed to angels.
Invisible and immortal. According to the teachings of the Church, the angels — sexless-invisible spirits who are immortal from the day of their creation. There are many angels, which follows from the old Testament description of God — "the Lord of the host". They form a hierarchy of angels and archangels of all the host of heaven. The early Church clearly divided the nine types, or "orders," angels, Seraphim, cherubim, thrones, dominions, powers, principalities, archangels, angels.
Angels served as intermediaries between God and his people. The old Testament says that no one could see God and remain alive, so direct communication between the Almighty and man is often portrayed as communication with an angel. It was the angel that kept Abraham from sacrificing Isaac. Moses saw an angel in a burning Bush, though the voice of God was heard. An angel led the Israelites during their Exodus from Egypt. From time to time, the biblical angels look just like mortals until their true nature is revealed, like the angels who came to Lot before the horrific destruction of Sodom and Gomorrah.
Nameless perfume. Other angels are mentioned in Scripture, such as the spirit with the fiery sword, who blocked Adam's way back to Eden; cherub and Seraphim, depicted in the form of storm clouds and lightning, which reminds of the faith of the ancient Jews in the God of thunderstorms; the messenger of God, who miraculously rescued Peter from prison, in addition, the angels who appeared to Isaiah in his vision of heavenly judgment: "I Saw the Lord sitting on the throne high and exalted, and the edges of his robe filled the whole temple. Around Him stood the Seraphim; each one had six wings; with two he covered every face, and with two he covered his feet, and with two he flew".
Hosts of angels appear several times in the pages of the Bible. Thus, the choir of angels announced the birth of Christ. Archangel Michael commanded numerous heavenly host in battle with the forces of evil. The only angels in the old and New Testaments who have their own names are Michael and Gabriel, who brought Mary the news of the birth of Jesus. Most of the angels refused to identify themselves, reflecting the popular belief that revealing the name of the spirit diminishes power.
