Best reference book on the Messages from the Sacred Heart of Jesus Christ and the Blessed Virgin Mary to Berthe Petit on the Devotion to the Sorrowful and Immaculate Heart of Mary, along with a detailed biography of the messenger, Berthe Petit. Jesus states, The hearts of men must be changed. This will only be realized through the devotion known, developed, preached and counseled everywhere...Recourse to my Mother under the title I wish for her universally, is the last help I shall give before the end of time...My Mother has acquired from her Heart the title of 'Sorrowful' by sharing generously in all the sufferings of My Heart and My Body from the crib to the cross...The title of 'Sorrowful' belongs therefore to the Heart of My Mother, and more than any other, this title is dear to Her because it springs from the union of her Heart with Mine in the redemption of humanity. Many black and white photographs. Imprimatur; Nihil Obstat.
