This paper aims to analyze the female characters of Muriel Spark from the viewpoint of religiosity. Unlike Graham Greene or Evelyn Waugh, Spark hardly uses religious theme in overt form, but rather in such an "economic" way that common readers easily miss it. An ardent admirer of Cardinal John Henry Newman and herself a Roman Catholic convert from Anglicanism, she states that she felt released from the oppressive stress of being a writer by her conversion. Her view of the novel changes as well. She started writing novels, utilizing them as a form in which to explore the ultimate religious meaning of human relationship or lack of it. She is always more interested in the spiritual status than the superficial social activities of her characters. Although she never openly claimed herself to be a feminist, Spark can be considered one in that she chose to edit the letters of Mary Shelley as well as those of Emily Bronte¨. Besides, most of her main characters are female. She stages not only women who attain self-discovery, maturity and dignity to encounter the Other and "transcendental" sensibility but also women of extreme egotism and blind selfishness who can never recognize or allow the otherness of the Other into their view of the world. This paper categorizes Spark`s female characters into four types: the woman of self recognition in personal hardship, the woman imitating God, the woman of transcendental vision of divine Providence, and the woman of narrow-mindedness who falls victim to her own selfishness. January Marlow of Robinson, Jean Brodie of The Prime of Miss Jean Brodie, Dame Lettie Colston. Charmien and Jean Taylor of Memento Mori aptly represent the four different types of Spark`s female characters.
