St. Faustina Kowalska was a Polish nun and mystic who received visions of Jesus Christ and was entrusted with spreading the Divine Mercy devotion. Her diary, Divine Mercy in My Soul, details her encounters with Christ and His message of mercy for the world. She was canonized by Pope John Paul II in 2000 and is known as the Apostle of Divine Mercy.
St. Maria Faustina Kowalska was born on August 25, 1905, in Głogowiec, Poland, into a poor but devout Catholic family. From an early age, she felt a strong call to religious life. At 20, she joined the Congregation of the Sisters of Our Lady of Mercy, dedicating herself to a life of prayer and service.
In 1931, she experienced a vision of Jesus Christ, who appeared to her wearing a white robe with rays of red and white light emanating from His heart. He instructed her to paint an image of what she saw, with the words "Jesus, I trust in You." This image became the foundation of the Divine Mercy devotion, emphasizing God's boundless love and mercy for all sinners.
Throughout her life, St. Faustina had numerous mystical experiences, including visions, messages from Jesus, and prophetic insights. She recorded these in her diary, Divine Mercy in My Soul, which has since become one of the most important spiritual texts of modern Catholicism.
Jesus also gave her the Divine Mercy Chaplet, a prayer meant to be recited, especially at 3:00 PM, the hour of Christ’s death, as a plea for mercy upon the world. Through her efforts, the Feast of Divine Mercy was later established on the first Sunday after Easter, fulfilling Christ’s request.
Despite suffering from tuberculosis and enduring severe physical and spiritual trials, she remained faithful to her mission. She died on October 5, 1938, at the age of 33, offering her sufferings for the salvation of souls.
She was canonized by Pope John Paul II on April 30, 2000, making her the first saint of the new millennium. Today, her legacy continues to inspire millions through the Divine Mercy devotion, the Chaplet, and the Feast of Divine Mercy.
