If you want a good summary on why fighting the culture wars is a bad idea (and a corollary: why theonomy failed to change anything), I recommend Leithart’s The Kingdom and the Power. (This is before he went full FV, and P&R published it, so it is safe).
We can even find a Covenanter angle to this if we want to: Reforming worship.
This might even give content to the utterly meaningless statement by Calvinists today: “Reformed and Always Reforming.” I ask young turk Calvinists what that statement means and I usually get something along the lines of “Publishing a new tract on the 5 Points.” “Always Reforming,” no matter how often it is abused, connotes “motion” and movement; not repeating the same stuff over and over.
Start singing the psalms in worship.
Have a denomination sponsor a critical evaluation of the Red Trinity hymnal.
For those in the South, start looking for Baptistic elements in your service and ask why they are there.
For those in the North, stop imitating Redeemer Presbyterian models.
There you go: in one minute I have given four concrete reasons for “Reformed and Always Reforming.” Publishing a new tract on TULIP won’t revitalize your church. Reforming worship will.
