"In our opinion nothing so clearly proves the assistance of the Holy Spirit and the necessity for a ruling power in the bosom of the Church as this law of harmonious development. It would seem that those who reject the idea of such a power are obliged either to ignore all that is done by that power and to raise up an entirely new Church, or to take the illogical and insincere method of adopting for their own a part only of the Church's institutions and rejecting the rest."
