The observance of Lent is the very badge of the Christian warfare. By it we prove ourselves not to be enemies of the cross of Christ. By it we avert the scourges of divine justice. By it we gain strength against the prince of darkness, for it shields us with heavenly help. Should mankind grow remiss in their observance of Lent, it would be a detriment to God's glory, a disgrace to the Catholic religion, and a danger to Christian souls. Neither can it be doubted that such negligence would become the source of misery to the world, of public calamity, and of private woe.
