Tobias became blind. "The loss of his eye-sight," says St. Augustine, "was the occasion for the old man to receive an angelical physician" (Fourth Lesson).
St. Raphael, a name meaning "God heals", was sent by God to cure Tobias as He sent the angel who moved the water in the pool called Probatica (Gospel). He told the younger Tobias what remedy he was to use to restore his father's sight, accompanied and protected the young man on his journey, helped him to find a wife and warded off the wiles of the devil. "We praise with sentiments of veneration," the Church sings, "all the princes of heavenly court, but in a special manner the archangel Raphael, healer and faithful companion, who chained down the devil under his power. O Christ, King of all goodness, by giving us such a guardian, make it impossible for the enemy to do us harm " (Hymn).
" May the angel Raphael, physician of our salvation, help us from the heights of heaven, heal all diseases and guide our faltering steps towards the true life " (Hymn at Lauds).
Benedict XV extended his feast to the universal Church.
