John Chrysostom
What profit is there from words you do not understand? And what am I saying, he continues, that this is unprofitable among us, and that only what is clear and intelligible to the hearers is profitable?
The same can be seen even in soulless musical instruments. If, for example, you blow into a flute or strike a harp without proper rhythm and harmony, but confusedly and at random, you will give pleasure to none of the hearers.
For even from inarticulate instruments a certain clarity is required. If you strike a harp or blow into a flute without skill, you will accomplish nothing.
If we require such clarity, order, and distinctness from soulless objects, and if we strive and labor to give great meaning to meaningless sounds, then much more is meaningfulness required from living and rational men, and from spiritual gifts.
