“"And I heard the sound of their wings, as the sound of many waters." In sacred speech, peoples are customarily designated by waters. Hence it is said through John: "The waters are peoples." Peoples are designated by waters for this reason: because in life they have sound from the tumult of the flesh, and daily they flow away through the course of mortality. As we have now often said, the wings of the living creatures are the virtues of the saints. What then does it mean that the prophet hears the sound of wings as the sound of many waters, except that by the mercy of almighty God those wings of virtues, which formerly sounded in few saints, now also, with preaching spread abroad, resound in the conversion of many peoples? For when the Lord was incarnate, suffered, and rose again, the winged living creatures were few, because those who desired heavenly things and raised themselves on high by the wings of virtues were very rare. But after the preaching of his divinity was spread throughout the world, how many little ones, how many older persons, how many strong youths, how many weak ones, how many converted sinners, how many aged virgins fly to heavenly things through faith, through hope, through love—who is able to tell, who to estimate? Behold, the sound of wings, which formerly was in few living creatures, now resounds among peoples, now the wings of virtues lift the multitude of the world to heavenly desire. Well therefore is it said: "And I heard the sound of their wings, as the sound of many waters," because, as we said before, that sound of virtues which was made in God's ear formerly from few saints was afterward multiplied from many waters, that is, from innumerable peoples.”
