Roman Catholic in origin, the Sacred Heart devotion emerged from Margaret Mary Alacoque’s experiences between 1673 and 1675, when she experienced visions of Jesus Christ. 

I could plainly see His heart, pierced and bleeding, yet there were flames, too, coming from it and a crown of thorns around it. He told me to behold His heart which so loved humanity. Then He seemed to take my very heart from me and place it there in His heart. In return He gave me back part of His flaming heart.
