According to Christian tradition, every one of us has a Guardian angel, who accompanies us from the moment we’re born until the moment of our death, and stays at our side at every moment of our life. The idea of a spirit, of a supernatural entity that follows and supervises every human being, was already present in other religions and in Greek philosophy. In the Old Testament, we can read that God is surrounded by a genuine court of heavenly figures who worship Him and perform actions in His name. Even in these ancient books, there are frequent references to angels sent by God as protectors of people and individuals, as well as messengers. In the Gospel, Jesus invites us to respect even the smallest and humble, in a reference to their angels, who watch over them from heaven and contemplate the face of God at every moment.
