The Prayer of the Servant of God Prosper Guéranger for the Protection of Poland

From Dom Prosper Guéranger's Liturgical Year:

Enjoy thy well-earned rest in heaven, O Casimir! Neither the world with all its riches, nor the court with all its pleasures, could distract thy heart from the eternal joys it alone coveted and loved. Thy life was short, but full of merit. The remembrance of heaven made thee forget the earth. God yielded to the impatience of thy desire to be with him, and took thee speedily from among men. Thy life, though most innocent, was one of penance, for knowing the evil tendencies of corrupt nature, thou hadst a dread of a life of comfort. When shall we be made to understand that penance is a debt we owe to God, a debt of expiation for the sins we have committed against him? Thou didst prefer death to sin; get us a fear of sin, that greatest of all the evils that can befall us, because it is an evil which strikes at God himself. Pray for us during this holy Season, which is intended as a preparation for penance; impress our minds with the truths now put before us. The Christian world is honoring thee today; repay its homage by thy blessing. Poland, thy fatherland, is in mourning; comfort her. She was once the bulwark of the Church, and kept back the invasion of schism, heresy, and infidelity; and now she is crushed by tyrants, who seek to rob her of her faith; pray for her that she may be freed from her oppressors, and, by regaining her ancient zeal for the faith, be preserved from the apostasy into which her enemies are seeking to drive her.
