Belief in angels is not limited to Christian traditions. The Christians inherited Jewish understandings of angels, which in turn may have been partly inherited from the Egyptians. Angels to Christians represented the spirit of love and messengers of the Spirit of God in Jesus the Christ

The angels are represented throughout the Christian Bible as a body of spiritual beings intermediate between God and men: “You have made him (man) a little less than the angels …” (Psalms 8:4-5). Some Christians believe that angels are created beings, and use the following passage as evidence: “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 …” (Psalms 148:2-5; Colossians 1:16). The Fourth Lateran Council (1215) declared that the angels were created beings. The Council’s decree Firmiter credimus (issued against the Albigenses) declared both that angels were created and that men were created after them. The First Vatican Council (1869) repeated this declaration in Dei Filius, the “Dogmatic constitution on the Catholic faith”. Of note is that the Bible describes the function of angels as “messengers” and does not indicate when the creation of angels occurred.

Adherents of The Church of Jesus Christ of Latter-day Saints (generally referred to as “Mormons”) view angels as the messengers of God. They are sent to mankind to deliver messages, minister to humanity, teach doctrines of salvation, call mankind to repentance, give priesthood keys, save individuals in perilous times, and guide humankind. –Wikipedia
