The Divine Institutes

Pleasure of the ears is received from the sweetness of voices and strains, which indeed is as productive of vice as that delight of the eyes of which we have spoken. For who would not deem him luxurious and worthless who should have scenic arts at his house? But it makes no difference whether you practice luxury alone at home, or with the people in the theatre. But we have already spoken of spectacles: there remains one thing which is to be overcome by us, that we be not captivated by those things which penetrate to the innermost perception. For all those things which are unconnected with words, that is, pleasant sounds of the air and of strings, may be easily disregarded, because they do not adhere to us, and cannot be written. But a well-composed poem, and a speech beguiling with its sweetness, captivate the minds of men, and impel them in what direction they please. Hence, when learned men have applied themselves to the religion of God, unless they have been instructed by some skilful teacher, they do not believe. For, being accustomed to sweet and polished speeches or poems, they despise the simple and common language of the sacred writings as mean. For they seek that which may soothe the senses. But whatever is pleasant to the ear effects persuasion, and while it delights fixes itself deeply within the breast. Is God, therefore, the contriver both of the mind, and of the voice, and of the tongue, unable to speak eloquently? Yea, rather, with the greatest foresight, He wished those things which are divine to be without adornment, that all might understand the things which He Himself spoke to all.

Therefore he who is anxious for the truth, who does not wish to deceive himself, must lay aside hurtful and injurious pleasures, which would bind the mind to themselves, as pleasant food does the body: true things must be preferred to false, eternal things to those which are of short duration, useful things to those which are pleasant. Let nothing be pleasing to the sight but that which you see to be done with piety and justice; let nothing be agreeable to the hearing but that which nourishes the soul and makes you a better man. And especially this sense ought not to be distorted to vice, since it is given to us for this purpose, that we might gain the knowledge of God. Therefore, if it be a pleasure to hear melodies and songs, let it be pleasant to sing and hear the praises of God. This is true pleasure, which is the attendant and companion of virtue. This is not frail and brief, as those which they desire, who, like cattle, are slaves to the body; but lasting, and affording delight without any intermission. And if any one shall pass its limits, and shall seek nothing else from pleasure but pleasure itself, he designs for himself death; for as there is perpetual life in virtue, so there is death in pleasure. For he who shall choose temporal things will be without things eternal; he who shall prefer earthly things will not have heavenly things.
