For how shall we fill people with blind faith in the correctness of a doctrine, if we ourselves spread uncertainty and doubt by constant changes in its outward structure? ...Here, too, we can learn by the example of the Catholic Church. Though its doctrinal edifice, and in part quite superfluously, comes into collision with exact science and research, it is none the less unwilling to sacrifice so much as one little syllable of its dogmas... it is only such dogmas which lend to the whole body the character of a faith.
