Through the years I've read a good few books on progressive theology—on both sides of the issues. (And there are many!) An interesting book worth reading is Wildfire: How Progressive Theology is Impacting the Church. The author is Daren Overstreet (Tampa, FL).

It’s unsettling when you don’t quite know what it is or why it’s happening. This book identifies a major cause of that shift and why it is occurring, making it a must-read for all who care about the future of God’s church.

Note: Although based originally on atheistic and even communist premises, Critical Theory, criticized in Wildfire, can be a useful tool for examining the structures of society.

Overstreet's approach to racial issues may be questionable, although on other topics he has much to offer. May these issues never become divisive in our fellowship.
