When a person thinks about change in his local church, he usually has a number of practical concerns on his mind (timing, type of change, people's acceptance, etc.). However, the most basic of these concerns is whether or not Christianity is subject to change.

Current patterns should not only allow but also encourage the basic ministry principles to operate.
