At age 14, she understood her vocation was to pray for priests, to be "an apostle to apostles". In September 1890, at her canonical examination before she professed her religious vows, she was asked why she had come to Carmel. She answered "I came to save souls, and especially to pray for priests". Throughout her life she prayed fervently for priests, and she corresponded with and prayed for a young priest, Adolphe Roulland, and a young seminarian, Maurice Bellière. She wrote to her sister "Our mission as Carmelites is to form evangelical workers who will save thousands of souls whose mothers we shall be."
