This study explores the connections between gender and sexual identity and Christian sacramental theology and practices in the light of contemporary debates around these issues in the churches. It approaches the sacraments from the perspective of Queer theory and theology drawing upon the work of two contemporary Christian mystics who have claimed to observe the inner workings of the sacraments. In this way Elizabeth Stuart shows how, from a Christian perspective, identity may be forged in the liturgical space between worlds and what the implications of such an understanding may be for contemporary discussion around these issues within Western Christianity.
