Allegory of the Holy Eucharist by Miguel Cabrera, 1750 pd

"Out of devotion to the Holy Eucharist and the Passion of Christ grew the devotion to the Sacred heart of Jesus with its feast and that of the S. Priesthood of Christ (Octave of Corpus Christi), and the more recent feast (1921) of the Eucharistic Heart of Jesus on the Thursday following the third Sunday after Easter. (American Ecclesiastical Review V 68, 1923 page 470)

"This devotion does not substantially differ from the ordinary devotion to the Sacred Heart. It merely emphasizes the act of supreme love of the Heart in bestowing the gift of the Holy Eucharist upon us." The Raccolta

On 9 November 1921, Pope Benedict XV instituted the feast of the Eucharistic Heart of Jesus to be celebrated on the Thursday within the Octave of the Sacred Heart with a Proper Mass and Office. The feast continues to be celebrated in some places. In instituting the feast, Pope Benedict XV wrote:  "The chief reason of this feast is to commemorate the love of Our Lord Jesus Christ in the mystery of the Eucharist. By this means the Church wishes more and more to excite the faithful to approach this sacred mystery with confidence, and to inflame their hearts with that divine charity which consumed the Sacred Heart of Jesus when in His infinite love He instituted the Most Holy Eucharist, wherein the Divine Heart guards and loves them by living with them, as they live and abide in Him. For in the sacrament of the Holy Eucharist He offers and gives Himself to us as victim, companion, nourishment, viaticum, and pledge of our future glory."  The Raccolta

"122. It is likewise Our most fervent desire that all who profess themselves Christians and are seriously engaged in the effort to establish the kingdom of Christ on earth will consider the practice of devotion to the Heart of Jesus as the source and symbol of unity, salvation and peace. Let no one think, however, that by such a practice anything is taken from the other forms of piety with which Christian people, under the guidance of the Church, have honored the divine Redeemer. Quite the opposite. Fervent devotional practice towards the Heart of Jesus will beyond all doubt foster and advance devotion to the Holy Cross in particular, and love for the Most Holy Sacrament of the Altar. We can even assert - as the revelations made by Jesus Christ to St. Gertrude and to St. Margaret Mary clearly show - that no one really ever has a proper understanding of Christ crucified to whom the inner mysteries of His Heart have not been made known. Nor will it be easy to understand the strength of the love which moved Christ to give Himself to us as our spiritual food save by fostering in a special way the devotion to the Eucharistic Heart of Jesus, the purpose of which is - to use the words of Our predecessor of happy memory, Leo XIII - "to call to mind the act of supreme love whereby our Redeemer, pouring forth all the treasures of His Heart in order to remain with us till the end of time, instituted the adorable Sacrament of the Eucharist."(122) For "not the least part of the revelation of that Heart is the Eucharist, which He gave to us out of the great charity of His own Heart."(123). (Encyclical Haurietis Aquas Pope Pius XII May 15, 1956).
