The guardian angel, a central figure in the Christian faith, is not a canonized saint, but rather a theological concept deeply rooted in Scripture and tradition. Their veneration is based on the belief that God assigns each individual a guardian angel, a heavenly messenger tasked with guiding, protecting, and interceding for us. This belief, present since the Old Testament (Psalm 91:11-12), developed in the New Testament with references by Jesus himself (Matthew 18:10). The feast of the Guardian Angels, celebrated on October 2nd, was established to honor these celestial spirits and recognize their essential role in the lives of the faithful. Devotion to the guardian angel is an invitation to cultivate a personal relationship with one's divine protector, trusting in their guidance and unconditional love.
