Marguerite Bays was a 19th-century Swiss seamstress and mystic who lived in the canton of Fribourg. A member of the Secular Franciscan Order, she dedicated her life to prayer and serving the impoverished in her community. She is notably remembered for her mystical experiences, including the reception of the stigmata and periodic ecstatic raptures. Following her death in 1879, her reputation for holiness led to a formal recognition of her virtues, culminating in her canonization by Pope Francis in 2019.
