I've frequently come across objections to pietism in Reformed theologies (and also Lutheran; for example W. Pannenberg said something like, "There is one thing I am certainly not; I am certainly not a pietist.") Mostly, however, they're just that: objections, not systematic discussions of the problems of pietism.
Can anyone please point me to orthodox Protestant writers tackling this subject systematically? I'm mostly interested in the theological and practical issues, not so much historical ones with the original movement. I'm posting here in the Reformed forum as I already have a ton of Reformed theologies in my Logos library and would like to start from there...
Thanks in advance!
