Parchment and Pen offers some detailed analysis of Bevere’s work. His conclusion:
I want to wind this up by saying that while I find Bevere’s position as taken particularly in the early portion of Under Cover utterly problematic on many levels, and truly dangerous to the spiritual health of the church, in the latter part of the book he tries to qualify some of the positions he has taken early in the book. The problem I see is the qualifications, which are well stated and carefully articulated, cut against the larger broad brush strokes that he has painted from the beginning.
As I said earlier, much of what he says is good. But the framework he uses is one that is the cyanide in the Kool-Aid. While he may not go down this path himself, working out the implicit presuppositions of his teaching, I don’t have to be a prophet to foresee that his followers will. And when they do they will unleash a new torrent of spiritual abuse that effectively undermines the freedom produced by the gospel and enslaves God’s children in chains of bondage. In so doing they will come under the same curse that Paul pronounced upon those who were adding to the gospel Paul proclaimed to the Galatian church.
What I found particularly heartening are his final comments about how Covering Theology adds to the gospel and puts people under a curse.
