Angels

The core concept of an angel is that of a spiritual or supernatural being,  often depicted as a messenger of a divine power or a messenger sent to convey a divine message or perform a specific task on behalf of a higher power, and are often seen as serving the will of God, with specific types like Archangels, Cherubim, and Seraphim having different duties and roles In some traditions, such as Catholic theology, angels are organized into different ranks or orders based on their proximity to God or their specific responsibilities. 

The term originates from the Hebrew and Greek words mal'akh, meaning "messenger" or "one who is sent," and is the root word for "angel." Angels feature prominently in many religions, particularly the Abrahamic faiths—Judaism, Christianity, and Islam —where they are believed to serve God, deliver messages, provide guidance, and protect humanity. They are generally considered to be non-physical or spiritual entities. However, they can sometimes appear in human or other physical forms, such as Divine beings that appear to people in material form, looking like handsome or beautiful people. In Islam, angels are seen as beings of light, created for specific tasks, possessing no ill intentions, and remaining pure. The term "earth angel" is a contemporary concept that refers to individuals with a strong, innate desire to help others, spread compassion, and bring light and love to the world.
