Paradigm Shift is a theological apologetic for his methodology and conclusions. Both are necessary for church development, and both poles are implied in the New Testament concept of ekklesia. Each of these poles stimulates the other. Problems development when one pole is emphasized over the other and thus becomes defining. There is danger to the left and to the right.
Balance is the key.
There are times when I find myself disagreeing with Schwarz. A local church needs a clear identity. Although a 'both-and' position may be right from a wider point of view, this does not usually apply on the level of the local church. Furthermore, there are times when I feel he overstates his case. To repeat the main point briefly institutions can and should be passed on.
