Feast of The Eucharistic Heart of Jesus (Thursday after the Sacred Heart)

One of the shortest lived Feasts in history. Instituted by Pope Benedict XV in 1921, it fell victim to Bugnini's Deforms of 1954.

From A Catholic Life

By Matthew Plese, TOP

On this date, we celebrate the Feast of The Eucharistic Heart of Jesus, which occurs on the Thursday within the traditional Octave of the Sacred Heart.

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 and by some communities, notably by the Redemptorists who maintain it in their Proper Calendar. 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.

Prayer to the Eucharistic Heart of Jesus

Eucharistic Heart of Jesus,/gracious companion of our exile,/I adore Thee.

Eucharistic Heart of Jesus,/lonely Heart,/humiliated Heart,/abandoned Heart,/forgotten Heart,/despised Heart,/ outraged Heart,/Heart ignored by men,/Heart which loves our own hearts;/Heart pleading for our love,/Heart so patient in waiting for us,/Heart so eager  to listen to our prayers,/Heart so anxious for our requests,/Heart, unending source of new graces,/Heart so silent, yet desiring to speak to souls,/Heart, welcome refuge of the hidden life,/Heart, teacher of the secrets of union with God,/Heart of Him Who sleeps but watches always,/Eucharistic Heart of Jesus, have mercy on us.

Jesus Victim,/I desire to comfort Thee;/I unite myself to Thee;/I offer myself in union with Thee.

I regard myself as nothing in Thy Presence./I long to forget myself in order to think only of Thee,/
to be despised and forgotten for love of Thee./I have no desire to be understood or loved by anyone but Thee.

I will keep silent in order to listen to Thee,/and I will abandon myself in order to lose myself in Thee.

Grant that I may thus satisfy Thy thirst for my salvation,/Thy burning thirst for my holiness,/and that once purified I may give Thee a sincere and pure love./I am anxious not to tire Thee further with waiting:/take me, I hand myself over to Thee./I give Thee all my actions,/my mind to be enlightened,/my heart to be directed,/my will to be stabilized,/my wretchedness to be relieved,/my soul and body to be nourished by Thee.

Eucharistic Heart of my Saviour,/Whose Blood is the life of my soul,/may I myself cease to live and Thou alone live in me. Amen.

(Indulgence 500 days. Brief, February 6, 1899, Leo XIII; Sacred Penitentiary Apostolic, November 8, 1934).

Collect:

O Lord Jesus Christ, who hast poured forth the riches of Thy love for men in instituting the Sacrament of the Eucharist: help us, we beseech Thee, to love Thy most loving Heart and ever make worthy use of so great a Sacrament: 

Who livest and reignest with the Father and the Holy Ghost God, world without end.

℟. Amen.
