The primary aim of this thesis is to explore the biographies and theologies of non-normative Christians. Prioritising the importance of sharing life stories as a source for theology, this thesis mobilises self-produced narratives from three individuals. By exploring the lives of the protagonists, we see how biographies and beliefs are revisited and revised throughout individual life courses. Mobilising resistance and rupture as characteristics of queer theory, I engage in a process which breaks free from traditional research paradigms. Thus, the secondary aim of this work became the development of an 'undoing' methodology, which liberates the researcher and allows me to approach and analyse the life stories using intuitive, reflective and creative methods. My critical insights on these participant stories reveal that all theologies are fluid, thereby exposing the temporal nature, but not significance, of all theology. Theologising from the basis of experience is always subject to revision. The process of 'undoing' theology points to a belief system based on experience which can never be rigidly fixed. The thesis reveals how 'undoing' theology is characterised by contingency, temporality, fluidity, becoming and unbecoming as its key indicators.
