'Christianity is not to be considered as a single point or a narrow, repetitive line, but as a circle which provides form but within which there is freedom to move in terms of understanding and expression. Christianity is a circle with definite limits, limits which tend to be like twin cliffs. We find ourselves in danger of falling off on one side or on the other; that is, we have to be careful not to avoid one sort of doctrinal error by backing off into the opposite one.
We must ask God to help us, and we must hep each other, not to fall off the cliffs. There is room for discussion within each circle, but we must not forget that there is a circle to be in.'
Francis A Schaeffer, The Church Before the Watching World, p.93.
