For a doctrine that is actually right in its main features it is less dangerous to retain a formulation which may no longer be quite adequate instead of trying to improve it and thereby allowing a fundamental principle of the movement, which had hitherto been considered as solid as granite, to become the subject of a general discussion which may have unfortunate consequences. This is particularly to be avoided as long as a movement is still fighting for victory. For would it be possible to inspire people with blind faith in the truth of a doctrine if doubt and uncertainty are encouraged by continual alterations in its external formulation?
