Here is an excellent case in point.
Thou by a vision made known to Your renowned bishop [St. Ambrose – RdP] the spot where lay the bodies of Gervasius and Protasius, the martyrs (whom You had in Your secret storehouse preserved uncorrupted for so many years), whence You might at the fitting time produce them to repress the feminine but royal fury. For when they were revealed and dug up and with due honour transferred to the Ambrosian Basilica, not only they who were troubled with unclean spirits (the devils confessing themselves) were healed, but a certain man also, who had been blind many years, a well-known citizen of that city, having asked and been told the reason of the people's tumultuous joy, rushed forth, asking his guide to lead him there. Arrived there, he begged to be permitted to touch with his handkerchief the bier of Your saints, whose death is precious in Your sight. When he had done this, and put it to his eyes, they were immediately opened. Thence did the fame spread; thence did Your praises burn—shine; thence was the mind of that enemy, though not yet enlarged to the wholeness of believing, restrained from the fury of persecuting. [Confessions IX.7, emphasis added]
St. Augustine’s respect for the relics of the holy martyrs was that of a Catholic.
