While many believe that they are the same thing, angels and cherubim do not appear to be synonymous. Within the same books in the Bible both beings are referred to with specific purpose. Angels, on the one hand, are spirits, just as you and I are spirits. These spirits have either not yet received a body (such as Michael, the archangel who later became the first man, Adam) or have already lived and passed on to the next life. Some examples of this are Noah, who was later the angel Gabriel, and Moroni, who ushered in the restoration of the gospel with the Book of Mormon. Angels are also referred to as “men of God” in the Old Testament, such as the angels who saved Lot in Sodom and the angels who informed Abraham of his upcoming parenthood. Contrary to popular believe, angels do not have wings. These beings could not have been mistaken by some as men had they large feathery wings protruding from their shoulder blades.
On the other hand, we have cherubim. Each time they are mentioned, so are their one or more sets of wings. Cherubim were sculpted on the arc of the covenant (with wings) at the direction of the Lord. Cherubim appear in the book of Revelation, singing praises to the Lord (also with wings). It was cherubim who were placed to guard the tree of life in the Garden of Eden with a flaming sword. These beings appear to be separate entities.
One final note on angels. Some might ask where all this information leaves us on the subject of guardian angels. While there is no scriptural mention that individuals have specific angels assigned to them to watch over and protect them, the scriptures do tell us that God’s angels will bear us up, lest we dash our foot against a stone. It is a belief among some, including myself, that our guardian angels are the spirits of our deceased loved ones or our future descendants. There is not much officially written by any church on this subject. You must look into your own heart and discover what is true.
