Dilexit Nos: On the Human and Divine Love of the Heart of Jesus Christ
125 When Saint Claude de La Colombière learned of the experiences of Saint Margaret Mary, he immediately undertook her defence and began to spread word of the apparitions. Saint Claude played a special role in developing the understanding of devotion to the Sacred Heart and its meaning in the light of the Gospel.
