Mystics of the Church founded by Jesus.

Sister Consolata Betrone was born in Saluzzo, Italy on April 6, 1903, and was named Pierina Betrone.
Here as seen below is a little leaflet in my possession, with permission to reprint.
RE: – Words spoke by Jesus to Sister M, Consolata a Capuchin Nun.
“Think, One act of love can determine eternal happiness for a soul. Therefore, be careful never to omit one ‘JESUS, MARY I love you, save souls: Lose no time every act of love is a soul.”

Words of Our Lady: “Only in paradise will you realize the value and the fruitfulness of saving souls. The act of love is especially meritorious as one of reparation.”

“One JESUS, MARY, I LOVE YOU, SAVE SOULS atones for thousands of blasphemies.”

Put together all virtuous acts of today that you can perform, and put them beside a day uninterrupted in acts of love, and I will take the love-filled day in preference to anything else you have done or offered Me. JESUS, MARY, I LOVE YOU, SAVE SOULS: Herewith you offer Me everything.”

“Remain true to this act of love, and renew it from hour to hour, and I will grant you everything, Consolata.”
“Consolata, I will lead you to all eights of love and suffering, but always repeat: JESUS, MARY, I LOVE YOU, SAVE SOULS: Nothing more.”
“I prefer one act of love to all other prayers. JESUS, MARY, I LOVE YOU, SAVE SOULS” includes all the souls in purgatory, as those in the militant Church, the guilty and the innocent, the dying, the godless, etc. Fear not: On the day you die, you will have reached the summit and finished your last act of love that Jesus wised from you, when He called you as a Victim of Love.”
Jesus wills to save the world, but the world must return to Jesus. There is only one way.
