Gibson’s movie begins in the garden of Gethsemane, with the disciples sleeping as Jesus prays for guidance and stomps on a snake that tempts him to avoid his destiny. There are other horrors: a screeching creature that resembles a berserk monkey , demonic children who might have wandered in from “The Exorcist,” a bird that plucks out the eyes of crucified men , the gargoyle-like members of King Herod’s court,. . .

Emmerich began having supernatural visions very early in her life
A few years ago, as Mel Gibson was rediscovering and renewing his Catholic faith, Mel Gibson purchased a library of hundreds of books from a closed nunnery. Mel claims as he was reaching for a book on the library shelf a supernatural intervention caused another book to “miraculously” drop into his hands. And that “miracle” book, not the Bible, not the Gospels, is the inspiration of The Passion . 
The book was The Dolorous Passion of Our Lord Jesus Christ according to the Meditations of Anne Catherine Emmerich. Gibson claims like “magic” this book opened up a new world. “‘ Amazing images ,’ he said. ‘She supplied me with stuff I never would have thought of”.
According to her biographers, the last 12 years of Anne’s life she ate no food except the bread and wine of the Holy Eucharist
Anne was born on the feast of the Virgin Mary’s own nativity: e a nun of the Augustinian Order at Dulmen.
By the age of four she prayed for three hours daily while being physically visited by her guardian angel. Even at that early age people around her described a “mysterious power that emanated from her.”
Emmerich was found frequently practicing the occult art of levitation. Many times when she entered a room, she was clearly seen levitating above the ground. She also practiced the occult art of astral projection, claiming to “bilocate” to various places. Astral Projection is the physic ability when the soul leaves the physical body and travels beyond space and time. During her mystic astral projections, she claims to have watched the actual execution of King Louis XVI, and visited Marie Antoinette, queen of France, in prison. Some times these astral projection trips actually took her into purgatory to view the tortured souls in purgatory. Of course, the Bible does not teach purgatory. Emmerich experienced about every satanic supernatural and occult practices known.
Emmerich also bore the actual, physical wounds of Jesus Christ, called the Catholic mystic stigmata, where the actual wounds of Christ supernaturally appear on the hands, feet and head. According to supposedly verified medical reports, her supernatural stigmata wounds were half an inch in size and found in her hands, feet, side, head and bled profusely, especially on Fridays (the Catholic’s erroneous day of the crucifixion). At times the blood flowed so heavy from the supernatural stigmata wounds, the blood would completely soak the bandages and freely flow on the ground. According to various sources, this was all verified by medical dined Emmerich said, “There can be no question of imposture in this case. The wounds speak for themselves, at least to a man of science. To ascribe them to natural causes such as imagination, induction, analogy, or similar causes, is simply impossible.”
Emmerich experienced common occurrences of supernatural visions. During these visions she claims to have “seen” the creation of Heaven, the fall of the angels, the creation of the earth, paradise and many other such scenes. During these demonic visions she also claims to have “seen” the actual crucifixion of Jesus Christ take place. Anne wrote a book titled, The Dolorous Passion of Our Lord Jesus Christ from these visions. And according to Mel Gibson, these demonic crucifixion visions, called the Dolorous Passion, became the “supernatural imposed” script and inspiration for The Passion – not the Gospels. This was the book that “supernaturally” fell into his hands that became the script and inspiration for The Passion .
