Translated and edited by Péronne-Marie Thibert, V. H. M. Introduction by Jo Ann Kay McNamara. A remarkable letter describing how the Visitation Sisters at Lyons escaped from France during the French Revolution, taking with them their most precious relic, the actual heart of Francis de Sales. The Introduction by the author of Sisters in Arms: Catholic Nuns through Two Millennia, highlights the significance of the letter in its historical context and S. Péronne Marie situates it and its author, Mother Marie-Jéronyme Vérot, in Visitation history.
