Q10
How does the 1950s setting affect St. Agatha's story?
The 1950s setting is crucial to St. Agatha because it establishes the social constraints that make Mary vulnerable. As a pregnant, homeless woman in 1957, her options were extremely limited. The era's strict religious authority and gendered expectations created institutions like the convent that could operate with little oversight. The donor system and social rituals of the time also show how the convent maintains its power through wealthy supporters.
