Dorothy Day was founder of the Catholic Worker Movement in the 1930s. Day was not raised with any particular religious conviction. She occasionally attended services in an Episcopalian Church, but lost her faith as a teenager and young adult. Day was very concerned with the social order, and strongly felt that changes needed to be made, which she promoted through journalism. Day's conversion to Catholicism occurred while she was working in New York. After her conversion, she founded the Catholic Worker Newspaper, which evolved into the most influential movement of Catholic social teaching.
