Born in 1905, the third of ten children, she was baptized as Helena in the Church of St. Casimir in the little village of Świnice Warckie, located in the Polish provincial seat of Lodz.
She worked as a housekeeper before joining the Congregation of the Sisters of Our Lady of Mercy in 1925, taking the name of Sr. Maria Faustina, and then working as a cook, gardener and porter in three of their houses.
In addition to carrying out her work faithfully, serving the needs of the sisters and the local people, Sister Faustina also had a deeply spiritual interior life, which included receiving revelations mystically from the Lord Jesus, which she recorded in her diary at the request of Christ and of her confessors.
At a time when some Catholics tended to view God as a judge so strict that they might be tempted to despair about the possibility of being forgiven, it was through His revelations to St. Faustina that Jesus chose to emphasize His mercy and forgiveness for sins, as long as they were acknowledged and confessed.
In one of His revelations, our Lord said to St. Faustina, “I do not want to punish aching mankind, but I desire to heal it, pressing it to my merciful heart.” The familiar image of the Divine Mercy, revealed to St. Faustina, shows two rays emanating from Christ’s heart, which symbolize the blood and water poured out after Jesus’ death, representing the healing and sanctifying graces, especially of Baptism and the Eucharist, that flow from the Sacred Heart of Jesus toward mankind.
St. Maria Faustina died of tuberculosis in Krakow, Poland, on October 5, 1938. She was beatified in 1993 by Pope St. John Paul II and he canonized her seven years later.
O GOD who didst endue thy holy Virgin Saint Faustina Kowalska, with grace to witness a holy life: grant that we, after her example and aided by her prayers, may be found ready when the Bridegroom cometh, and enter with him to the marriage feast; through the same Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
