Of the Church Hymns Instituted at Milan; Of the Ambrosian Persecution Raised by Justina; And of the Discovery of the Bodies of Two Martyrs
15 Not long had the Church of Milan begun to employ this kind of consolation and exhortation, the brethren singing together with great earnestness of voice and heart. For it was about a year, or not much more, since Justina, the mother of the boy-Emperor Valentinian, persecuted Your servant Ambrose in the interest of her heresy, to which she had been seduced by the Arians. The pious people kept guard in the church, prepared to die with their bishop, Your servant. There my mother, Your handmaid, bearing a chief part of those cares and watchings, lived in prayer. We, still unmelted by the heat of Your Spirit, were yet moved by the astonished and disturbed city. At this time it was instituted that, after the manner of the Eastern Church, hymns and psalms should be sung, lest the people should pine away in the tediousness of sorrow; which custom, retained from then till now, is imitated by many, yea, by almost all of Your congregations throughout the rest of the world.
16. Then Thou by a vision made known to Your renowned bishop 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. Thanks be to You, O my God. Whence and whither have You thus led my remembrance, that I should confess these things also unto You—great, though I, forgetful, had passed them over? And yet then, when the “savour” of Your “ointments” was so fragrant, did we not “run after You.” And so I did the more abundantly weep at the singing of Your hymns, formerly panting for You, and at last breathing in You, as far as the air can play in this house of grass.
