In these approved apparitions under the title of Our Lady, Queen of the Universe, the Blessed Virgin began appearing in 1937 in Heede, Germany to four girls. According to the International Marian Research Institute at the University of Dayton:
“The Heede apparition appears to be a follow up on the Fatima event and promotes its message (it is deplored that mankind had ignored the Fatima messages). Apparitions of other holy persons are reported (Jesus himself and the “angel of justice”). … The seers were reportedly told of a coming “minor judgment.” It was only after wonderful cures occurred that the parish priests and other clergy supported the seers… The bishop of Osnabrück at the time the apparitions commenced, appointed a new parish priest who declared that there are “undeniable proofs of the seriousness and authenticity of these manifestations.”” [1]https://udayton.edu/imri/mary/h/heede-apparitions.php
Later, in 1945, Jesus appeared to the same seers with His own revelations, exhorting obedience to the earlier messages of His mother, and adding [2]http://www.therealpresence.org/eucharst/misc/BVM/146_HEEDE_140x96.pdf:
I am coming! I am at the door! My love has planned this action before the creation of the world… The world lies in dense darkness. This generation would deserve to be wiped out; but I wish to show Myself merciful… I am coming Myself and I will manifest My will… The things that will come shall surpass by far what happened. The Mother of God, My mother, and the Angels will take part in it. Hell by now believes itself certain of victory, but I will take it away… I am coming, and with Me, peace shall come. I will build my Kingdom with a small number of elect. This Kingdom will come suddenly, sooner than what one thinks. I will make My light shine, which to some will be blessing and to others darkness. Humanity will recognize My love and My power.

Through what became The Spiritual Diary, Jesus and Mary taught Elizabeth, and they continue to instruct the faithful in the divine art of suffering for the salvation of souls. Tasks are assigned for each day of the week, which involve prayer, fasting, and night vigils, with beautiful promises attached to them, laced with special graces for priests and the souls in purgatory. In their messages, Jesus and Mary say that The Flame of Love of the Immaculate Heart of Mary is the greatest grace given to mankind since the Incarnation. And in the not-so-distant future, her flame will engulf the entire world.

Thirdly, the messages have frequently been accompanied by visible phenomena, photographic evidence found in In Cammino con Maria, which cannot be the fruit of subjective imagination, notably the presence of the stigmata on Giselle’s body and and the appearance of crosses or religious texts in blood on Gisella’s arms.

of the saints. It wasn’t until she became a “Daughter of Mary” that the nightmares finally ceased at the age of eleven. In the following year, Jesus began to speak interiorly to her especially after receiving Holy Communion. When she was thirteen, He appeared to her in a vision that she witnessed from the balcony of her home. There, in the street below, she saw a crowd and armed soldiers leading three prisoners; she recognized Jesus as one of them. When He arrived beneath her balcony, He raised his head and cried out: “Soul, help Me!” Deeply moved, Luisa offered herself from that day on as a victim soul in expiation for the sins of mankind.
immobile, rigid-like state that appeared almost as if she were dead. It was only when a priest made the sign of the Cross over her body that Luisa regained her faculties. This remarkable mystical state persisted until her death in 1947—followed by a funeral that was no little affair. During that period in her life, she suffered no physical illness (until she succumbed to pneumonia at the end) and she never experienced bedsores, despite being confined to her little bed for sixty-four years.
