Life and Doctrine of Saint Catherine of Genoa

Caterina Fieschi Adorno (1447–1510) wrote nothing herself. The Vita mirabile e dottrina santa, printed in Genoa in 1551, four decades after her death, is the work of the circle that gathered around her in her last years: her confessor Cattaneo Marabotto, who began directing her in 1499, and her disciple Ettore Vernazza, the Genoese notary and founder of hospitals for the incurable. They recorded her sayings, her account of her conversion, and her teaching, and from that material the book was assembled. It contains three parts: a narrative of her life, the Treatise on Purgatory, and the Spiritual Dialogue between the soul, the body, self-love, and the spirit. Behind it stands a woman married at sixteen to a dissolute nobleman, who after ten years of misery was overwhelmed by the love of God in a single moment in March 1473 while kneeling for confession, and who then spent the rest of her life nursing the sick at the Pammatone hospital, eventually governing it, without ever entering a religious order.

The doctrine is a doctrine of pure love. Catherine's governing word is that God is love and nothing but love, and that the soul's whole task is to let that love burn away everything in it that is not God. She speaks with unusual violence about self-love, which she calls the root of all misery, and with unusual tenderness about the soul's hunger for union. The Treatise on Purgatory is her most original contribution. Purgatory, as she describes it, is not a sentence imposed from outside but something the soul chooses. Seeing clearly at death both the beauty of God and the rust still clinging to it, the soul throws itself into the purifying fire as a lover rushes toward the beloved, and its suffering and its joy are the same thing: the pain of impediment and the delight of being drawn. She insists that no suffering in this world or the next can compare with the pain of a soul that sees God and cannot yet reach him, and that no joy can compare with the contentment of being purified. The Dialogue dramatizes the same combat within a single person, the spirit gradually subduing body and self-love until the soul is wholly surrendered.

The book shaped Catholic teaching on purgatory for centuries and drew readers far beyond Italy. Friedrich von Hügel built his Mystical Element of Religion around her, and his critical study established that the 1551 text is a layered compilation rather than a single hand's work. Benedict XVI devoted a general audience to her in 2011, holding up her life as the union of mystical fire with service to the sick poor.

Who should read this: those who want a lay, married, hospital-working mystic rather than a cloistered one, and anyone whose picture of purgatory is only punishment. It is not for readers seeking a tidy biography or a systematic theology; the text is uneven, repetitive, and ecstatic, and it rewards slow rereading rather than a single pass.
