The notion that the church, the press, and the universities should serve the state is essentially a Communist notion. In a free society these institutions must be wholly free - which is to say that their function is to serve as checks upon the state.
What is held by the whole Church, and that not as instituted by Councils, but as a matter of invariable custom, is rightly held to have been handed down by authority.
The mere change of custom, even though it may be of advantage in some respects, unsettles men by reason of the novelty: therefore, if it brings no advantage, it does much harm by unprofitably disturbing the Church.
