Regarded politically, never was any measure devised to which the interest of France and the Emperor was more diametrically opposed. Napoleon nominally gained the city of Rome, which, without this step, it was in his power to occupy at any time; but he lost the support, and incurred the mortal hatred of the Catholic clergy, and of all whom they could influence. He unravelled his own web, and destroyed, by this unjust and rash usurpation, all the merit which he had obtained by the re-establishment of the Gallican Church. Before this period he had said of the French clergy, and certainly had some right to use the language, "I have re-established them, I maintain them--they will surely continue attached to me." But in innovating upon their religious creed, in despoiling the Church, and maltreating its visible Head, he had cut the sinews of the league which he had formed betwixt the Church and his own government. It is easy to see the mistaken grounds on which he reckoned. Himself an egotist, Napoleon supposed, that when he had ascertained and secured to any man, or body of men, their own direct advantage in the system which he desired should be adopted, the parties interested were debarred from objecting to any innovations which he might afterwards introduce into that system, providing their own interest was not affected. The priests and sincere Catholics of France, on the other hand, thought, and in conscience could not think otherwise, that the Concordat engaged the Emperor to the preservation of the Catholic Church, as, on the other hand, it engaged them to fealty towards Napoleon. When, therefore, by his unprovoked aggression against the Head of the Church, he had incurred the spiritual censure of excommunication, they held, by consequence, that all their engagements to him were dissolved by his own act. [Sidenote: PIUS THE SEVENTH.] The natural feelings of mankind acted also against the Emperor. The Pope, residing at Rome in the possession of temporal power and worldly splendour, was a far less interesting object to a devout imagination, than an old man hurried a prisoner from his capital, transported from place to place like a criminal, and at length detained in an obscure Italian town, under the control of the French police, and their instruments.[14]
