The Guardian Angel, a central figure in the Christian faith, is not a "saint" in the traditional sense of a canonized person, but rather a spiritual entity. Its veneration is rooted in the biblical belief that God assigns each individual a guardian angel, a celestial messenger tasked with guiding, defending and interceding for man. This belief, already present in the Old Testament (Psalm 91.11-12), is strengthened in the New Testament with the words of Jesus (Matthew 18.10). The Catholic Church celebrates the feast of Guardian Angels on October 2, recognizing their fundamental role in the spiritual life of the faithful. They are seen as silent and powerful companions, witnesses of our existence and intercessors with God, a bridge between the divine and the human.
