Next Thursday evening I will have a lecture about Garabandal in our town in Germany. After a short introduction about the events, first I will show the film "The Message of Garabandal" and after a break the second film "Garabandal - The Eyewitnesses". I believe there will be many questions about Garabandal after these two films. Among the visitors will be some critics. A young woman, who soon will go in a convent, told me a few days earlier : "I can’t believe in Garabandal, because the Blessed Mother promised to the American Joey Lomangino, that he would get back his eyelight on the day of the miracle. But now he died. He has neither got back his eyes, nor has the miracle entered. What should I answer? Can someone give me help? What prophecies have already been fulfilled concerning Garabandal?
If you go to the thread 'Garabandal News', there is tons of information there on Garabandal and if you have any queries ask Glenn there as he is the expert on all things related to Garabandal.
I am not even half as experienced as others here about Garabandal but I read a good explanation for some of what you are looking for in the following article, http://garabandal.weebly.com/#/members/, best wishes to you! As for prophecies being fulfilled maybe you should go on to the Garabandal News thread and see if someone there can direct you. Off the top of my head, the seer's denial, the roads being built, the ban lifted on mass being said there, of course the little miracle (the Eucharist) - verify these with Glenn on the other thread also.
I think the 'Little Miracle of the Host' is perhaps the biggest prophesied event that has already occurred in Garabandal. You can read all about it at: http://www.ourlady.ca/eucharist/miraclestroy.htm And you can view the miracle as it was captured on a few frames from a cine camera here:
