St. Margaret Mary Alacoque, Apostle of the Sacred Heart of Jesus, received the unique favor of being visited by Our Lord Himself, who asked her to spread devotion to His Most Sacred Heart. This she most humbly did, once she had received the permission and approbation of her superiors, especially her spiritual director and confessor, St. Claude La Columbiere.

For all Catholic men and women, families and young people troubled by the many afflictions of modern life here is the greatest source of spiritual and temporal help, graces and blessings for those who truly love the Sacred Heart of Our Lord, Jesus Christ, and practice His requested Devotion with the essential prayers and acts including the "First Friday's". The Nine "First Fridays" must be made in honor of His Sacred Heart on nine consecutive months, and communion must be received.
