Abstract: In the Netherlands, religions are often positioned as opposite to secular ideals of women’s freedom. While women’s emancipation supposedly grants women their autonomy, religions are suspected of reaffirming gender inequality. In this religion-versus-emancipation dilemma, questions of the body are pertinent, since traditional religions are framed as restricting and regulating women’s bodies. Questions about modesty, sexual relations, clothing and food preparations often come up in such debates. There seems to be a particular tension for women who convert to religions that are often regarded as ‘gender conservative’, and this chapter sheds light on that field of tension. This expands the field of women’s conversion – which has typically focused on Islamic women – by employing a comparative analysis of interviews and participant observation with Jewish, Christian and Muslim Dutch women converts. Joining a religion that one was not raised in is a process of ethical self-fashioning through training and disciplining of both the body and mind. Converts have to learn how to eat, how to pray, how to dress and how to have sex in such a way that it permits them to give shape to their religious subjectivity and pious desires. What I found is that performing authenticity is a central and embodied characteristic of modern-day conversion stories in the ‘age of authenticity’. This performance is often played out through the sexual and gendered body and religious subject transformations were closely related to sexual self-fashioning. In order to understand these links between conversion, sexuality and the body, I focus on experiences and ideas about virginity and marriage, menstruation and homosexuality. In this chapter, I aim to show that sexual embodiments and ethics cannot be understood as either religious or secular, but rather as a new form of religious subjectivity within Europe as a space where authenticity has become the most important mode for selfhood.
