In Book X of Confessions, Augustine probes the matter of the pleasures of the senses. He does not want to allow his senses to control him, whether it is sight or sound. He recognizes that when his senses refuse to take "second place," there can be a problem. This applies to what he hears, including Church music. He is concerned that the music will overtake the message. He is concerned that he will love the music more than he will love the content. He leans to approval of the matter, but still is cautious:
So I waver between the danger that lies in gratifying the sense and the benefits, which as I know from experience, can aaccrue from singing. Without committing myself to an irrevocable opinion, I am inclined to approvae of the custom of singing in church, in order that by indulging the ears weaker spirits may be inspired with feelings of devotion. Yet when I find the singing itself more moving than the truth which it conveys, I confess thiat this is a grievous sin, and at those times I would prefer not to hear the singer.
The issue of music in Church is not a new one. While Augustine struggled with the temptation to let his senses take control and seek more the music that the content, we today experience something similar with being tempted to be more caught up in the presentation of the music than the content. Augustine was concerned that his senses not be in control. Have we ever thought of our response to worship music in such terms? It is possible to really be caught up in a song, thinking it is really powerful, but in reality, it is only the music we are drawn to. Writing good worship music is the marriage of a singable, pleasing melody with rich words. We have a lot of church music today that have great melodies and appalling words.
Augustine considers it a "grievous sin" when the song is more important than the truth. That's a strong statement. There are some songs I have sung in church which musically, are pleasing to the ear, but promote terrible doctrine. Would I be willing to consider that sin?
It's interesting to see that even back then, music was an issue in church.
