Faustina Kowalska
1905 — 1938
A Polish nun with only three years of formal education, Helena Kowalska entered the Congregation of the Sisters of Our Lady of Mercy in 1925 and became Sister Maria Faustina. Beginning in 1931 she recorded visions of Christ in her Diary, which gave the Church the Divine Mercy image, the Chaplet, and the feast day. Beatified in 1993 and canonized by John Paul II on April 30, 2000, she was the first saint he named of the new millennium.
