29 Accordingly, it has become the practice and determination under this condition of public polity (now so much admired by many) either to forbid the action of the Church altogether, or to keep her in check and bondage to the State. Public enactments are in great measure framed with this design. The drawing up of laws, the administration of State affairs, the godless education of youth, the spoliation and suppression of religious orders, the overthrow of the temporal power of the Roman Pontiff, all alike aim to this one end-to paralyse the action of Christian institutions, to cramp to the utmost the freedom of the Catholic Church, and to curtail her ever single prerogative.
