7 Another Psalm which was read says: “Who is like the Lord our God, Who dwells on high, and regards lowly things in heaven and in the earth?” The Lord regarded indeed lowly things when He revealed to His Church the relics of the holy martyrs lying hidden under the unnoted turf, whose souls were in heaven, their bodies in the earth: “raising the poor out of the dust, and lifting the needy from the mire,” and you see how He has “set them with the princes of His people.” Whom are we to esteem as the princes of the people but the holy martyrs? Among whose number Protasius and Gervasius long unknown are now enrolled, who have caused the Church of Milan, barren of martyrs hitherto, now as the mother of many children, to rejoice in the distinctions and instances of her own sufferings.
