"Dorothy Day regarded Elizabeth Gurley Flynn, for instance, who had joined the U.S. Communist Party in 1937, as "my sister in the deep sense of the word." Flynn, Day wrote, "always did what the laity is nowadays urged to do. She felt a responsibility to do all in her power in defense of the poor, to protect them gainst injustice and destitution" (Long Loneliness, 145-146)."
