The Roman Catholic Church has in recent decades sent mixed signals with regard to discrimination based on sexual identity. On the one hand, official documents have condemned violence and verbal abuse directed at persons of different sexual orientation; on the other hand, the Church has approved and lobbied for certain types of discrimination: in housing and employment, for example, and also with regard to marriage or civil unions. Sexual Diversity and Catholicism focuses specifically on Roman Catholic magisterial teachings on sexual diversity. It also wrestles with explicitly Roman Catholic views of the relationship among various sources of moral wisdom (between Church teachings, the Bible, philosophy, science and experience) and how their interplay might contribute to the further development of Church teaching. It addresses the issue of sexual diversity and its legitimate expression under the headings Interpreting Church Teachings, Interpreting the Bible, Interpreting Secular Disciplines, and Interpreting Human Experience.
