The insincerity of any proposed attachment to the American republic by popes or priests, is attested by the very occurrence of the Southern rebellion. Had the pope and priests been opposed to it a Catholic rebel would scarcely have been known; and had not the Catholics North and South been in favor of the rebellion, it could not have taken place. That singular and unnecessary intestine collision, in which the South gained nothing but disgrace, the North nothing but depopulation and empoverishment, and at the mystery of which leading secessionists were so much puzzled that they declared it to be the effects of a general lunacy, was nevertheless in perfect harmony with the profound and masterly policy of the Roman See, which comprehends in its toils the events of ages, and from the first projection of a plot to its final consummation, shapes every intervening circumstance to the fulfilment of its grand design. The Catholics North supported the cause of the Union, and the Catholics South the cause of the rebellion with votes, money and men; the rebellion, therefore, was not contrary to the teachings of the church. The depopulation of the native element of the North, the influx of foreign Catholics, the creation of an oppressive national debt, the demoralization consequent on civil war, the engenderment of civil antipathies, and the supplanting of colored servants by white Catholic servants, were all known prospective results of the rebellion; were all in harmony with the papal designs; and to realize which the Catholics of the North, and the Catholics of the South were stimulated by their priests to meet each in deadly conflict. But dismemberment could not possibly have been intended by the secret projectors of the rebellion. It was an impracticable idea. The geography of the country interposed to its success an insurmountable obstacle. It was also inconsistent with the papal designs. But monarchy was not an impracticable idea. It encountered no difficulty in the country's geography. It was in harmony with the policy of the Roman See. The Catholic blood which was poured out in such torrents in the civil conflicts was not intended to effect dismemberment, but to create the elements conducive to the establishment of a monarchial government. Shortly after the close of the rebellion this soil, hallowed by the blood, and consecrated by the sepulture of millions of freemen, Catholic as well as non-Catholic, was attempted to be desecrated by the establishment of presses for openly advocating that execrable treason; and it has been asserted by the leaders of the late rebellion, that the civil war is not at an end; but that it will again break out, and then the battle field will not be the South, but every State, city and village in the Union. Perhaps they mean to intimate that it will be a repetition of the massacre on St. Bartholomew's eve.
