This saint confirmed several dogmas of the Catholic Faith by the force of wonderful miracles, "the real presence of Jesus Christ in the most Holy Eucharist, the forgiveness of sins in the sacrament of Penance, the sufferings of hell, the glories of the blessed in heaven, the Divine Providence in our spiritual as well as temporal necessities, and the intercession of the saints. By this is seen the divine mercy in the amendment of sinners, the justice of God in punishing the wicked, and the wonderful effects of the omnipotent wisdom and goodness of God toward sinners." - Preface
