A guardian angel is an angel believed to be assigned to protect and guide individuals, groups, or nations, a concept rooted in ancient traditions from Judaism to Christianity. The idea evolved through theological texts, such as Pseudo-Dionysius’s angelic hierarchy, and literary works exploring their role as spiritual guides.
Authors like Thomas Aquinas emphasized their protective function during life’s journey, while Albert A. Lings observed their presence even after sin, highlighting their lasting significance. From biblical references to mystical writings, the guardian angel connects theological doctrine with the human desire for divine companionship, reflecting a universal theme of direction and security across cultures and eras.
