St. Faustina Kowalska

Faustina Kowalska was a Polish religious sister whose spiritual diary became central to Catholic devotion to Divine Mercy. Born Helena in 1905, she spent much of her life doing ordinary domestic work.

Her family had limited means, and her formal schooling was brief. Before entering religious life, she worked in households to support herself and assist her parents. In 1925 she joined the Sisters of Our Lady of Mercy and received the name Maria Faustina.

Assignments in several convents included cooking, gardening, and receiving visitors at the door. Alongside these duties she recorded experiences she understood as encounters with Christ. Her diary connected trust in God's mercy with active mercy toward other people.

The image, chaplet, and other practices associated with Divine Mercy spread through this spiritual legacy. They belong to Catholic private revelation and devotion, not additional books of Scripture. Faustina died of tuberculosis in Kraków on October 5, 1938. Canonized in 2000, she is remembered for a message whose international reach contrasts with the limited public prominence of her own lifetime.
