The Most Sacred Heart of Jesus
“We therefore urge all Our children in Christ, both those who are already accustomed to drink the saving waters flowing from the Heart of the Redeemer and, more especially those who look on from a distance like hesitant spectators, to eagerly embrace this devotion. Let them carefully consider, as We have said, that it is a question of a devotion which has long been powerful in the Church and is solidly founded on the Gospel narrative. It received clear support from tradition and the sacred liturgy and has been frequently and generously praised by the Roman Pontiffs themselves. These were not satisfied with establishing a feast in honour of the most Sacred Heart of the Redeemer and extending it to the Universal Church; they were also responsible for the solemn acts of dedication which consecrated the whole human race to the same Sacred Heart.”
“When so many evils meet Our gaze - such as cause sharp conflict among individuals, families, nations and the whole world, particularly today more than at any other time - where are We to seek a remedy, venerable brethren?“
“Can a form of devotion surpassing that to the most Sacred Heart of Jesus be found, which corresponds better to the essential character of the Catholic faith, which is more capable of assisting the present-day needs of the Church and the human race?”
“What religious practice is more excellent, more attractive, more salutary than this, since the devotion in question is entirely directed towards the love of God itself?”
(Pius IX, Haurietis Aquas)
