“Behold the Heart which has so loved men that it has spared nothing, even to exhausting and consuming Itself, in order to testify Its love; and in return, I receive from the greater part only ingratitude, by their irreverence and sacrilege, and by the coldness and contempt they have for Me in the Eucharist. But what I feel most keenly is that it is hearts which are consecrated to Me that treat Me thus. Therefore, I ask of you that the Friday after the Octave of Corpus Christi be set apart for a special Feast to honour My Heart, by communicating on that day, and making to It a solemn act in order to make amends for the indignities which It has endured during the time It has been exposed on the altars. I promise you that My Heart will expand Itself to shed in abundance the influence of Its Divine Love upon those who shall thus honour It, and cause It to be honoured.”
-Revelation of Our Lord to St. Margaret Mary Alacoque
