Pius IX. seemed to throw in his lot definitely with the revolution when, on the 19th of March, he too granted a Constitution, having previously formed a lay ministry, which included Marco Minghetti and Count Pasolini, under the presidency of Cardinal Antonelli, who thus makes his first appearance as Liberal Premier. That the Roman Constitution was an unworkable attempt to reconcile lay and ecclesiastical pretensions, that the proposed Chamber of Deputies, which was not to make laws affecting education, religious corporations, the registration of births and marriages; or to confer civil rights on non-catholics, or to touch the privileges and immunities of the clergy, might have suited Cloud-cuckoo-town, but would not suit the solid earth, were facts easy to recognise, but no one had time to pause and consider. It was sufficient to hear Pius proclaim that in the wind which was uprooting oaks and cedars might be clearly distinguished the Voice of the Lord. Such utterances, mingled with blessings on Italy, brought balm to patriotic souls. The Liberals had no fear that the Pope would veto the participation of his troops in the national war, for they were blind to the complications with which a fighting Pope would find himself embarrassed in the middle of the nineteenth century. But the other party discerned these complications from the first, and knew what use to make of them.
The powers of reaction had only to catch hold of a perfectly modern sentiment, the doctrine that ecclesiastics should be men of peace, in order to dissipate the myth of a Pope liberator. It was beside the question that, from the moment he accepted such a doctrine, the Pope condemned the institution of prince-bishoprics, of which he represented the last survival. Nor was it material that, if he adopted it, consistency should have made him carry it to its logical consequence of non-resistance. By aid of this theory of a peaceful Pontiff, with the threat, in reserve, of a schism, Austria felt confident that she could avoid the enormous moral inconvenience of a Pope in arms against her.
Either, however, the full force of the influence which caused Pius IX. to draw back was not brought to bear till somewhat late in the day, or the part acted by him during the months of March and April can be hardly acquitted of dissimulation. War preparations were continued, with the warm co-operation of the Cardinal President of the Council, and when General Durando started for the frontier with 17,000 men, he would have been a bold man who had said openly in Rome that they were intended not to fight.
