On 15 May 1956 and on the 100th anniversary of the establishment of the Feast of the Sacred Heart of Jesus, Pius XII issued the encyclical Haurietis Aquas (You will draw water).

Pius XII used this encyclical to encourage greater devotion to the Heart of Jesus both because it is united to the “Person of the Incarnate Son of God Himself” and because it is a sign of the love of Jesus for all people. Pius XII also stressed that devotion to the Sacred Heart is for all people and designed to encourage growth in faith today.

Both John Paul II and Benedict XVI have referred to this encyclical in their own encouragement of a greater love of the Sacred Heart.
