A Polish nun whose apparitions of Jesus Christ inspired the Roman Catholic devotion to the Divine Mercy and earned her the title of 'Apostle of Divine Mercy'.
Saint Faustina Kowalska, born Helena Kowalska, was a Polish nun of the Congregation of the Sisters of Our Lady of Mercy. She is globally recognized for her visions of Jesus Christ and her revelations concerning Divine Mercy, which she documented in her diary, known as 'Divine Mercy in My Soul'. These revelations led to the establishment of the Divine Mercy devotion, including the image of Merciful Jesus, the Feast of Divine Mercy on the first Sunday after Easter, the Chaplet of Divine Mercy, and the Hour of Mercy (3:00 PM). Beatified in 1993 and canonized in 2000 by Pope John Paul II, she has become a central figure in contemporary Catholic spirituality.
