For almost fifty years, through her tireless service to the poor and her courageous witness for peace, Dorothy Day offered an example of the gospel in action. Now the publication of her diaries, previously sealed for twenty-five years after her death, offers a uniquely intimate portrait of her struggles and concerns. Beginning in 1934 and ending in 1980, these diaries reflect her response to the vast changes in America, the Church, and the wider world. Day experienced most of the great social movements of her time but, as these diaries reveal, even while she labored for a transformed world, she simultaneously remained grounded in everyday human life: the demands of her extended Catholic worker family; her struggles to be more patient and charitable; the discipline of prayer and worship that structured her days; her efforts to find God in all the tasks and encounters of daily life. A story of faithful striving for holiness and the radical transformation of the world, Day’s life challenges readers to imagine what it would be like to live as if the gospels were true.
