T. David Gordon gives eight reasons he thinks contemporary worship music will die away very soon. Not that it should die away (even though yes, it should), but that it will die away by virtue of its very nature.
Here are his reasons:
1. CWM hymns not only were/are comparatively poor; they had to be.
2. Early on in the CWM movement, many groups began setting traditional hymn-lyrics to contemporary melodies and/or instrumentation.
3. As a result, the better contemporary hymns (e.g. “How Deep the Father’s Love,” “In Christ Alone”) have been over-used to the point that we have become weary of them.
4. It is no longer a competitive advantage to have part or all of a service in a contemporary idiom; probably well over half the churches now do so, so we have reached what Malcolm Gladwell calls the “Tipping Point.”
5. As with all novelties, once the novelty wears off, what is left often seems somewhat empty.
6. Thankfully, my own generation is beginning to die. While ostensibly created “for the young people,” the driving force behind CWM was always my own Sixties generation of anti-adult, anti-establishment, rebellious Woodstockers and Jesus freaks.
7. CWM is ordinarily accompanied by Praise Teams, and these have frequently (but by no means always) been problematic.
8. We cannot evade or avoid the “holy catholic church” of the Apostles’ Creed forever.
