The Heart is simply an organ of our bodies, a vital organ, but nevertheless just an organ. But the heart, to man, is also a symbol:
And when a heart is presented to us as wounded, it is a symbol of love to the point of suffering, to the point of self sacrifice.
The devotion to the Sacred Heart, therefore, is not a devotion to the bodily organ but a devotion to Jesus’s love for us. It is not an affective devotion, the devotion of a detached, distant admirer (like a devotee gazing at a painting of his favourite artist in an art gallery); it is not a devotion of sentiment. It is nothing other than the devotion by which we make Jesus' effective love possible for us; the devotion which allows us to be loved by Our Lord Jesus Christ.
For we must understand that love does not exist in its true sense without communication, without a mutual will to the perfection of the other. One-sided love does not exist. Just as God cannot make the absurd possible, such as creating a square circle, God cannot love us with His divine love, cannot elevate us to participate in His Divinity without our reciprical love of Him.
When Our Lord died on the Cross, He completed our OBJECTIVE REDEMPTION, He died for all men. But for this redemption to be effective in us (our SUBJECTIVE REDEMPTION), in order that we win the prize, the crown for which we were made, we must love Our Lord voluntarily, freely, mutually.
My dear breathren, the devotion the Sacred Heart is an opening of the floodgates of Divine Love. It is through this devotion that we place a hand on the crown of Glory which is to LOVE GOD AS HE LOVES HIMSELF.
If you have not already done so, enthrone the Sacred Heart in your homes. Make a novena to the Sacred Heart during the month of June, and if you have not too many prayers at the end of your family rosary, make an short daily act of consecration to the Sacred Heart.
Finally, during this Mass, join your heart to Jesus’ living Heart in the Blessed Sacrament. Ask, through the Immaculate Heart of Mary that like her heart our hearts may be dilated by the treasures that pour forth the Heart of Her Divine Son.
