Margaret Anna Cusack, the founder of the Sisters of St. Joseph of Peace, was bold, courageous and visionary. She dedicated her life to fighting social injustice, especially toward the poor and woman and children. In 1884, she founded the Sisters of St. Joseph of Peace, a religious order whose members still actively live her founding charism of peace through justice. Based on Cusack's many books, biographies, letters and other research, Dorothy Vidulich, herself a Sister of St. Joseph of Peace, has written a concise study of Cusack's life. In particular, she has focused on Cusack's courage to confront the discrimination and injustice promulgated by society and a patriarchal church, which ultimately forced her to leave the religious order she had founded for it to be saved.
