This powerful collection sets out to be “orthodox and affirming”, and navigates this space with courage and aplomb. The authors demonstrate the richness of the Roman Catholic tradition in ways recognizable to practicing Catholics, and highlight how the tradition might offer new and valuable insights that ring true with trans people’s lives and self-conceptions. Driven by the principle of grace (sometimes hand in hand with righteous rage), the authors show that building peaceful constructive conversations about gender diversity cannot mean eliding or glossing over areas of real difference and disagreement. Through bringing together previously-published material and new original pieces, by both trans and cis scholars, the volume gets readers right up to date with discussions of trans identity informed by Catholic doctrine, teaching, and pastoral practice. It will be of great service in elevating the level of discourse on trans identity and Christianity.
