The broader theme of gender and Christian religion presupposes three definitions: of Christianity, of religion, and of gender. Probably none of these is as simple as it might first appear, but that of gender is perhaps the most critical for our theme. Although there are still some who would use the terms ‘gender’ and ‘sex’ interchangeably, there is a growing tendency to recognize an important distinction between gender – that is, femininity and masculinity, regarded as largely socially constructed – and sex, the biological distinction between male and female human beings. Gender is best considered as born out of interactions between men and women. This means that the gender roles which make up what we experience as masculinity and femininity cannot be defined by looking only at men or at women, although ideas about both can be gained from looking at one group or the other. That is why gender history is different from women’s history, and that is why both women’s history and gender history are essential enterprises. We need women’s history because we need to know where women were as well as where they were not.
