The guardian angel, a timeless figure in the Christian tradition, is not a canonized saint, but a spiritual entity. Its veneration is rooted in the belief that God assigns each individual a protecting angel from birth, in charge of guiding him, inspiring him to good and defending him from dangers. This belief, already present in the Old Testament (Psalm 91.11: "For he will command his angels concerning you to guard you in all your ways"), developed in the New Testament and in patristic theology. The feast of the Guardian Angels is celebrated on October 2, as proof of the importance of these celestial figures in the lives of the faithful. They are seen as divine messengers, intercessors and silent companions on the earthly path, a symbol of protection, hope and the constant presence of God.
