"This is My blood of the covenant,
which is poured out for many for the forgiveness of sins."
Matthew 26: 28
"Jesus knowing that His hour was come, that He should pass out of this world to the Father: having loved His own who were in the world, He loved them unto the end."
John 13: 1-2
Introit from Mass of the Feast of the Eucharistic Heart of Jesus
"You shall draw waters with joy out of the Savior's fountain."
This is beautiful scripture passage Pope Pius XII uses to open his encyclical on the Sacred Heart of Jesus. Haurietis Aquas (You shall draw waters) - the Latin title - was published on May 15, 1956 in honor of the 100th Anniversary of the establishment of the Feast of the Sacred Heart by Pope Pius IX.
In this profound encyclical, the Holy Father Pius XII refutes various arguments against devotion to the Sacred Heart and explores both the Old and New Testament as grounds for this devotion. He also expounds upon what such a devotion means for our spiritual life, that devotion to the Heart of Jesus is to love the heart of God.
"Devotion to the Sacred Heart is our response to the love of God,
revealed in the human Heart of Our Lord Jesus Christ."
