I was listening to local Catholic radio and someone said the largest apparition was when Marry appeared for several days to promote peace between Christians and Muslims and was seen by 3 million people. I totally missed what he said, where it was... any ideas?
The only thing I can think of is the apparitions in Egypt but Mary did not speak when she appeared there. https://www.thoughtco.com/virgin-marys-apparitions-assiut-egypt-124598 Maybe someone else has a better answer.
This is the one that I was actually thinking of. So I guess there was another set of apparitions in Egypt in the 2000's. Both appear similar no talking correct? The article that I posted focuses on the more recent one but mentions the earlier one briefly.
It was Zetiun in Egypt just about the time of the Six Day War between Israel and Egypt (and a lot of the rest of the Arab world). Mystical theologians call this kind of phenomenon a , 'Thoephany' (just as the miracle of the sun at Fatima was) and class it as the highest type of Mystical event because it is witnessed by many. I passed the Church in Cairo but could not get out to see it as we were on a tour bus. But it is a very striking Church. More like a Basilica. Among the many, many thousands of people who saw Our Lady was President Nasser of Egypt. It did much to ease interfaith tensions and probably saved the lives of thousands of Christians. You should watch the videos on utube they are marvellous.
