Today, the Church celebrates the Feast of the Sacred Heart of Jesus and tomorrow, the Feast of the Immaculate Heart of Mary (Friday, June 11 and Saturday, June 12, 2021). Devotion to both the Sacred Heart and the Immaculate Heart is encouraged three times in the Fatima message.
First, in the spring of 1916, the Angel of Peace spoke these words to the three children of Fatima: “The Hearts of Jesus and Mary are attentive to the voice of your supplications.”
Again in the summer of 1916, the Angel says: “The Holy Hearts of Jesus and Mary have merciful designs for you.”
Finally, in the fall of 1916, the angel dictates a prayer to the children which in part says: “And I draw upon the infinite merits of the Sacred Heart of Jesus and the Immaculate Heart of Mary that You might convert poor sinners.”
In addition, on several occasions, Jesus told Sister Lucia that He desired adoration of both hearts.
