Definition of guardian angel

The concept of guardian angels dates back to ancient civilizations, where they were believed to be spirit beings that protected and guided individuals. However, the specific phrase "guardian angel" is thought to have originated from Christian theology. In the Bible, there is no explicit mention of angels being assigned to individuals as personal protectors. However, the concept of angels serving as divine messengers or ministers can be found in both the Old and New Testaments. It was during the Middle Ages, when the Catholic Church promoted the worship of angels, that the idea of personal guardians gained popularity. Saint Thomas Aquinas, a prominent medieval theologian, wrote that each person has a guardian angel assigned to them at birth, with the duty of watching over and guiding them. The official explanation of the Catholic Church's teachings regarding the subject can be found in the Catechism, where it is stated that "from its origin until death, human life is surrounded by their [angel's] watchful care and intercession." The Greek Orthodox Church and some Protestant denominations also believe in the concept of guardian angels. In the Orthodox tradition, they are called "guardian spirits", while some Protestant denominations adopt varying terminology like "ministering spirits" or "watchful angels". In short, the phrase "guardian angel" as used today in Christian religious context refers to a heavenly being assigned to watch over and protect a particular person.
