In the year 1794, Holy Thursday fell on April 17th. The Poor Clares of Lyons were in prison during the French Revolution. The nuns implored a priest to leave them a consecrated host in a bag. He did so, and they hung the bag on a nail in the wall, and thus were able to have the Lord with them all night. One of the Sisters, Sister Mary Colette, set herself in such a way as to screen the Blessed Sacrament from observation in case of a surprise. Nothing, though, troubled their vigil.
