The Guardian Angel, a central figure in the Christian faith, is not a canonized saint but a spiritual entity. Its veneration is rooted in the Old Testament, where angels appear as divine messengers and protectors. In the New Testament, Jesus himself speaks of angels watching over children. The belief in the Guardian Angel developed over the centuries, consolidating in the Middle Ages and finding expression in theology and popular devotion. Each person, according to tradition, is accompanied by an angel who guides them, protects them from temptation and leads them towards good. The feast of the Guardian Angels is celebrated on October 2, an opportunity to honor these invisible travel companions and thank them for their constant presence and intercession.
