The Sisters of the Visitation wish to be especially faithful to the mission they have recieved to love and bring others to love the Sacred Heart. As St. Margaret Mary has written; "Although this treasure of love is a good everyone can claim and to which everyone has a right, it has hitherto been little known and now is especially given to the Daughters of the Visitation because they are called to honor His hidden life. Having been revealed to them, they are to make it known and share it with others"
*From The Holy Constitutions of the Order of the Visitation of Holy Mary
"St. Francis de Sales, during his life, made his abode in the Sacred Heart of Jesus, in which his repose was never interrupted by the most distracting occupations.
"Moses, by conversing familiarly with God, became the meekest of men, and our amiable Saint, by his intimate union with the divine Heart of Jesus, aquired in the most eminent degree, the two virtues of this Adorable Heart, by the practice of these two virtues, which are the foundation of the rules of the Daughter if the Visitation; and as the different orders, which are in the Church, are designed to honor some particular virtue of the Son of God, so that of the Visitation is established to render continual homage to the Sacred Heart of Jesus in His hidden and annihilated life. God was pleased to make this manifest by choosing St. Margaret Mary Alacoque (a religious of the Visitation), who died n 1690, to make known His will about the establishment of a feast in honor of His Adorable Heart, and to extend this devotion.
" 'Behold,' said our Divine Savior to her, 'this Heart which has loved man to such excess, that it has exhausted and consumed itself to testify His Love to him.' At another time, our Lord assured her that He took a singular complacency in seeing the interior sentiments of His Heart and His Love honored under the figure of a heart, and that He wished it to be exposed in public, in order that it might touch the insensible hearts of men. He promised, at the same time, that He would abundantly shed the treasures of grace, with which His Heart was filled, into the hearts of those who would honor it; and that wherever this image should be exposed to be particularly honored, there would He bestow every kind of blessing. Saint Margaret Mary asserts that she knows of no exercise of piety in the spiritual life better caculated to raise, in a short time, a soul to the highest state of sanctity, or to make it relish the true delight which is found in the service of God, than the devotion to the Sacred Heart of Jesus."
