The Guardian Angel, a central figure in the Christian faith, is not a canonized saint but a spiritual entity present since biblical origins. Its veneration is rooted in the Old Testament, where messenger and protector angels intervene in human affairs. In the New Testament, Jesus himself mentions the presence of guardian angels for the "little ones". Catholic doctrine, particularly from the Middle Ages, has developed the idea that each individual has an angel assigned by God to guide them, protect them from evil, and intercede for them. The feast of the Guardian Angels, celebrated on October 2nd, was established to honor this constant and loving presence in the life of every believer, emphasizing the role of these celestial beings as faithful companions on the spiritual path.
