2 No new events are these in the career of the Church militant. Jesus foretold them to His disciples. That she may teach men the truth and may guide them to eternal salvation, she must enter upon a daily war; and throughout the course of ages she has fought, even to martyrdom, rejoicing and glorifying herself in nothing more than in the occasion of signing her cause with her Founder's blood, the sure and certain pledge of the victory whereof she holds the promise. Nevertheless we must not conceal the profound sadness with which this necessity of constant war afflicts the righteous. It is indeed a cause of great sorrow that so many should be deterred and led astray by error and enmity to God; that so many should be indifferent to all forms of religion, and should finally become estranged from faith; that so many Catholics should be such in name only, and should pay to religion no honour or worship. And still sadder and more beset with anxieties grows the soul at the thought of the fruitful source of most manifold evils existing in the organisation of States that allow no place to the Church, and that oppose her championship of holy virtue. This is truly a terrible manifestation of the just vengeance of God, Who allows blindness of soul to darken upon the nations that forsake Him. These are evils that cry aloud, that cry of themselves with a daily increasing voice. It is absolutely necessary that the Catholic voice should also call to God with unwearied instance, "without ceasing;"(1) that the Faithful should pray not only in their own homes, but in public, gathered together under the sacred roof; that they should beseech urgently the all-foreseeing God to deliver the Church from evil men(2) and to bring back the troubled nations to good sense and reason, by the light and love of Christ.
