These two plaques in St. Pierre's Cathedral state that it was in this chapel that Therese attended Mass and Vespers on Sunday until she entered Carmel. Here, in July 1887, while closing her missal, she saw a holy card protrude from the edge in such a way that only the wounded hand of the Crucified was visible, and she understood her vocation to gather up this Precious Blood and "pour it out on souls."
