49. The delights of the ear drew and held me much more powerfully, but thou didst unbind and liberate me. In those melodies which thy words inspire when sung with a sweet and trained voice, I still find repose; yet not so as to cling to them, but always so as to be able to free myself as I wish. But it is because of the words which are their life that they gain entry into me and strive for a place of proper honor in my heart; and I can hardly assign them a fitting one. Sometimes, I seem to myself to give them more respect than is fitting, when I see that our minds are more devoutly and earnestly inflamed in piety by the holy words when they are sung than when they are not. And I recognize that all the diverse affections of our spirits have their appropriate measures in the voice and song, to which they are stimulated by I know not what secret correlation. But the pleasures of my flesh--to which the mind ought never to be surrendered nor by them enervated--often beguile me while physical sense does not attend on reason, to follow her patiently, but having once gained entry to help the reason, it strives to run on before her and be her leader. Thus in these things I sin unknowingly, but I come to know it afterward.
50. On the other hand, when I avoid very earnestly this kind of deception, I err out of too great austerity. Sometimes I go to the point of wishing that all the melodies of the pleasant songs to which David's Psalter is adapted should be banished both from my ears and from those of the Church itself. In this mood, the safer way seemed to me the one I remember was once related to me concerning Athanasius, bishop of Alexandria, who required the readers of the psalm to use so slight an inflection of the voice that it was more like speaking than singing.
However, when I call to mind the tears I shed at the songs of thy Church at the outset of my recovered faith, and how even now I am moved, not by the singing but by what is sung (when they are sung with a clear and skillfully modulated voice), I then come to acknowledge the great utility of this custom. Thus I vacillate between dangerous pleasure and healthful exercise. I am inclined--though I pronounce no irrevocable opinion on the subject--to approve of the use of singing in the church, so that by the delights of the ear the weaker minds may be stimulated to a devotional mood. Yet when it happens that I am more moved by the singing than by what is sung, I confess myself to have sinned wickedly, and then I would rather not have heard the singing. See now what a condition I am in! Weep with me, and weep for me, those of you who can so control your inward feelings that good results always come forth. As for you who do not act this way at all, such things do not concern you. But do thou, O Lord, my God, give ear; look and see, and have mercy upon me; and heal me--thou, in whose sight I am become an enigma to myself; this itself is my weakness.
