History of the devotion
Early devotion
Historically, the devotion to the Sacred Heart is an outgrowth of devotion to what is believed to be Christ's sacred humanity.During the first ten centuries of Christianity, there is nothing to indicate that any worship was rendered to the wounded Heart of Jesus.
The revival of religious life and the zealous activity of Bernard of Clairvaux and Francis of Assisi in the twelfth and thirteenth centuries, together with the enthusiasm of the Crusaders returning from the Holy Land, gave a rise to devotion to the Passion of Jesus Christ and particularly to practices in honour of the Sacred Wounds.
Devotion to the Sacred Heart developed out of the devotion to the Holy Wounds, in particular to the Sacred Wound in the side of Jesus. The first indications of devotion to the Sacred Heart are found in the eleventh and twelfth centuries in the fervent atmosphere of the Benedictine or Cistercian monasteries.
It is impossible to say with certainty what were its first texts or who were its first devotees.
Bernard of Clairvaux (d. 1153) said that the piercing of Christ's side revealed his goodness and the charity of his heart for humanity. The earliest known hymn to the Sacred Heart, "Summi Regis Cor Aveto", is believed to have been written by the Norbertine Herman Joseph (d. 1241) of Cologne, Germany. The hymn begins: "I hail Thee kingly Heart most high."
From the 13th to the 16th centuries, the devotion was propagated but it did not seem to have been embellished. It was everywhere practised by individuals and by different religious congregations, such as the Franciscans, Dominicans, and Carthusians. Among the Franciscans the devotion to the Sacred Heart of Jesus has its champions in Bonaventure (d. 1274) in his Vitis Mystica ("Mystic Vine") and John de la Verna.[11] Bonaventure wrote: "Who is there who would not love this wounded heart? Who would not love in return Him, who loves so much?"[12] It was, nevertheless, a private, individual devotion of the mystical order. Nothing of a general movement had been inaugurated, except for similarities found in the devotion to the Five Holy Wounds by the Franciscans, in which the wound in Jesus's heart figured most prominently.
Bonaventure's Opusculum 3, Lignum vitae (a part from which is the reading for the Divine Office on the Solemnity of the Sacred Heart) refers to the heart as the fountain from which God's love poured into one's life:
Take thought now, redeemed man, and consider how great and worthy is he who hangs on the cross for you. His death brings the dead to life, but at his passing heaven and earth are plunged into mourning and hard rocks are split asunder. It was a divine decree that permitted one of the soldiers to open his sacred side with a lance.
This was done so that the Church might be formed from the side of Christ as he slept the sleep of death on the cross, and so that the Scripture might be fulfilled: 'They shall look on him whom they pierced'. The blood and water, which poured out at that moment, were the price of our salvation.
Flowing from the secret abyss of our Lord's heart as from a fountain, this stream gave the sacraments of the Church the power to confer the life of grace, while for those already living in Christ it became a spring of living water welling up to life everlasting.
