Abstract
Issues surrounding transsexualism, especially when surgical operations have been performed to achieve the desired sex, can create serious problems for canon law. After an examination of how sex is determined, the author provides a clear explanation of transsexualism and then differentiates it from hermaphroditism, homosexuality, and transvestitism. Transsexualism’s effect on the liciety of marriage is analyzed, followed by an exploration of considerations regarding transsexualism and Holy Orders. Finally, transsexualism and the vowed religious life are examined. The author encourages those faced with such situations to pursue solutions that preserve, as well as possible, the good of the patient and their community, as well as the Church.
