Mary’s smile is a spring of living water. “He who believes in me”, says Jesus, “out of his heart shall flow rivers of living water” (Jn 7:38). Mary is the one who believed and, from her womb, rivers of living water have flowed forth to irrigate human history. The spring that Mary pointed out to Bernadette here in Lourdes is the humble sign of this spiritual reality. From her believing heart, from her maternal heart, flows living water which purifies and heals. (…) Mary is honoured with the title of Fons amoris, “fount of love”. From Mary’s heart, there springs up a gratuitous love which calls forth a response of filial love, called to ever greater refinement. Like every mother, and better than every mother, Mary is the teacher of love. That is why so many sick people come here to Lourdes, to quench their thirst at the “spring of love” and to let themselves be led to the sole source of salvation, her son Jesus the Saviour.
