After a look at the Madeleva Manifesto and noting that its emphasis on equality, dignity and justice echos the ideas of Catherine, the author examines Catherine's 14th-century life and ministry. She then uses that as a mirror through which to explore "three interrelated aspects of the source and authority of the works of faithful women in every age: 1) the authority of vocation, 2) the authority of wisdom and 3) the authority of compassion".
Hilkert believes that as we ponder what it means for women to speak with the authority of the Spirit, "Catherine's words and witness can offer insight and challenge".
