Haurietis aquas (Latin: "You will draw waters") is a landmark encyclical of Pope Pius XII. Written on May 15, 1956, it was attached to the 100th anniversary of the establishment of the feast of the Sacred Heart of Jesus by Pope Pius IX. The title is derived from Isaiah 12:3, a verse which alludes to the abundance of the supernatural graces which flow from the heart of Christ. Haurietis aquas made the whole Church, and not merely the Jesuits, recognize the Sacred Heart as an important dimension of Christian spirituality.
