What is the author's style in The Long Loneliness: The Autobiography of Dorothy Day by Dorothy Day?

Dorothy Day was an early twentieth century traditional Catholic. She was also deeply attracted to radical social activism. Her religious leanings began in early childhood and her discussion of religion and Catholicism in particular pervade the book. She also indirectly makes arguments for her faith, such as discussing the value of liturgy, the attractiveness of a supernaturalist approach to human suffering and vice, and a strong theological foundation for loving the poor and avoiding excessive materialism. She is never anti-Protestant, but speaks as if it is clear that the Roman Catholic Church is the one true church.
