Huk, Romana. "“A Single Liturgy”: Fanny Howe’s The Wedding Dress." Christianity & Literature 58.4 (2009): 657-93. Huk looks at the way the poet Fanny Howe uses the thought of Edith Stein and Simone Weil to reflect on her conversion to Catholicism. Ultimately, there is not much discussion of Weil's thought itself; the essay concerns itself more with Howe's response to and comments on Weil's life, especially her struggle with the thought of conversion and her commitment to social and political activism in the face of perceived injustice.
