Hymnbooks as theology

Incidentally, we should note here the importance of Christian hymns and songs as means of making doctrinal statements memorable and accessible to congregations. The hymnbooks of the Christian church are often its most important and most memorable statements of doctrine.—Alister McGrath, Theology: The Basics (2nd ed.), 92

And that, unfortunately given the lack of theology in most current songs, is still true. Would that more choruses and spiritual songs had more than just a pop theology to them! Or that people would rediscover the hymns.

Actually, I think it would be great if the entertainment version of "singing" would disappear and congregations could rediscover the joy of singing. It's good for the soul.
