The prayers of the Novena for the Poor Souls in Purgatory, penned by the great Doctor of the Church, St. Alphonsus Liguori, stand as a profound expression of the Catholic understanding of the Communion of Saints, the expiatory nature of Christ's sufferings, and the urgent need to offer prayers for the souls in Purgatory. Through this novena, we enter into the mysteries of Christ's Passion, invoking His redemptive suffering to obtain mercy for the Holy Souls who are undergoing purification.
 
In the meditations by Father Scott Haynes, which accompany each day of the novena, we contemplate the theological significance of the prayers of St. Alphonsus and draw from the wisdom of the saints and Church Fathers to deepen our understanding of this spiritual work of mercy.
